Benjamin Forstner was indeed born in Pennsylvania and migrated to Salem, Ore. at the end of the Civil War. By trade, he was a gunsmith. Boring and rifling gun barrels, he came up with a bit design (patented in 1874) that still carries his name. Forstner used the leading factories in New England to commercially produce his invention. One was the Colt Patent Fire Arms Co. of Hartford, CT.

[@lilolmecj]

I am so pleased with your comment. For two weeks I have been trying to think of the name Forstner! I was trying to describe them to hubby, for using on the lathe to hollow out vases etc. . And if I remembered to stop and pull out my set, while in the shop I could check. I had been pulling things together for years and years in my quest for turning wood. We got our lathe set up about 10 days ago! So exciting.

Benjamin Forstner (25 March 1834 - 27 February 1897), was an American gunsmith, inventor, and dry goods merchant. In 1886, Forstner patented the Forstner bit. The bit was revolutionary as it did not feature the lead screw (which Forstner called the "gimlet-point") or the cutting lips of more conventional wood boring bits, and thus proved especially useful to gunsmiths and high-end woodworkers. The spade bit is most commonly used in construction to drill fast rough holes through studs and joists for routing wires and tubing. It blows through the soft would very fast, and you don't care how clean the holes is just for routing.

[@reeceguisse17]

Forstner bitts changed my life! the attribute you didn't make much of, but was shown is the shape of the bottom of the hole. The center has a small divot and the outside edge has a small groove, but the rest is flat and smooth. This was GREAT news for me because I imbed T-Nuts in resin castings. With just a pick and a little sandpaper, I can get a very clean hole that centers and levels the T-Nut - something that the great honking divot and grooves of a spade bit made difficult.

[@TheHackettMan]

This is what I bought my set - wanted to countersink bolts and nuts for some planters, so forstner made that easy. Honestly didn't know I was buying something so special, but I love the bits.

[@NoName-zn1sb]

[@chris_wicksteed]

Old-timey augur bits, like the one Adam shows, potentially cut the cleanest holes in wood. They have two spurs around the edge that cut the wood fibres in advance of scraping the material out.

[@luthiermatt]

It was bugging me that he did not mention the spurs or the pilot screw that pulls the bit. Love my bit n brace setup.

Something I loved about having had wood and metal shop in school was getting to work with several types of drill bits. Our final project in wood shop was the little race cars powered by a CO2 cartridge And we used a forstner bit to drill the cavity for the cylinder

[@CaraesNaur]

Exactly, shop class is invaluable. I too did the CO2 cars in shop class. In junior high, no less. High school seniors are barely allowed to look at pictures of power tools nowadays. Which is very likely why it perplexed me very much to hear Adam say Forstner bits are obscure. Less well known than spade bits, sure, but nowhere near qualifying for a Buzzfeed clickbait list.

Over the years as a DIY homeowner I've had to approach a lot of projects requiring drilling. Early on my wife needed holes in the bottom of her planters. Plastics not a problem there you go! But eventually and she did bring me a ceramic planter??? It required a glass drill bit. And later trying to organize all of my Woodworking magazines in a 3 ring binder I required a paper punch drill bit. And when I installed hinges on my gates I needed a hinge drill bit. Coinciding with the gate build I had to drill a 3/4" hole into concrete with a masonry bit. I also had to use a step drill bit to modify a light fixture I was putting up. And of course while I was building my deck I used an 1-1/2" forstner drill bit to recess the hole so that the flat washer lock washer and nut could reach the bolt coming from the other side. Alongside the other drill bits Adam talked about that's a lot of specialty used drill bits. Who'd a thunk? Thanks for putting this up Adam!

[@jeffsimpson9232]

One important thing you left out about that auger is that the little screw-threaded tip (sometimes called the snail) draws the bit through the work. This means you don't have to apply any force in the direction of the bore, you just need to turn the brace. Longer throw braces (they go up to 14 inches AFAIK) make this really easy even in very hard woods.

It's more suited for novice to intermediate, rather than the more experienced user. 360 pages. About 80 pages devoted to identifying tools. That includes the drill bits Adam covered plus, a few more. There's a Hardware section, including types of nails, screws, bolts, fasteners and, many other fixtures. It covers materials and, the use of tools to work with those material. Clamping, soldering, sharpening... Heaps of home and garden projects. It's a very good resource for figuring out what you may need for a job. ..or, building a wish list.

Well... I know these professional builders that were really succesful, and appreciated for both prices and quality at the same time. They once told me they bought the cheapest brand of cement blenders in bulk, and threw them away after each project instead of cleaning them, because that would cost them more time and money than it was worth cleaning them...

[@akareject]

From Wikipedia: Benjamin Forstner (25 March 1834 - 27 February 1897), was an American gunsmith, inventor, and dry goods merchant. In 1886, Forstner patented the Forstner bit. The bit was revolutionary as it did not feature the lead screw (which Forstner called the "gimlet-point") or the cutting lips of more conventional wood boring bits, and thus proved especially useful to gunsmiths and high-end woodworkers. The bit was unsurpassed in drilling a smooth-sided hole with a flat bottom. It was also better than Russell Jennings twist bits for boring at an angle and not following the grain of the wood. Forstner eventually made arrangements for the manufacturing and sale of his bit with two Connecticut firms: Colt's Manufacturing Company of Hartford, and Bridgeport Gun Implement Company, successors to Union Metallic Cartridge Company. The Forstner bit continues to be manufactured, although it has evolved into a split-ring design. Also, modern Forstner bits normally feature a (non-screw) lead point (AKA "center spur"), unlike Forstner's original, although rim-guided bits are still available from some manufacturers.

[@peterjf7723]

Thanks for that information, I had never thought to look up the origin of Forster bits.

[@tapwetugeye]

[@jobney]

I learned about and used Forstner bits in middle school woodshop (about 1989-1991). As an adult, I was a little surprised to not see a whole aisle of them in the big box HW stores.

[@petergriffin4629]

I have a great drill bit story to share here. My dad is a tool maker and engineer by trait. He used to work with a local racer and motorcycle tuner. One time they were trying to drill holes in the flyweight of a crankshaft to in order rebalance the crankshaft with tungsten. The purpose of this was to increase inertia, because the bike was too sharp on throttle response, while decreasing the overall weight. However, the crankshaft was hardened on it's outer layer and they just couldn't get through that hardened layer with anything in their machine shop. So finally they just drove to the hardware store and bought an ordinary drill for concrete drilling and with that and a lot of cooling liquid they go through. The reason obviously being that super hard plate inserted into the tip of a drill like that.

[@sjmww1235]

Linemen use the auger bits to drill mounting holes for transformers in wood poles. Either in hydraulic or electric drills

[@sixstringedthing]

I ran into Forstner bits a year or two ago when I built a pinball machine... they're great for putting flipper buttons into ply. Great thing about them is you can drill half way into the wood with a larger bit then finish it with a smaller bit and it'll still centre itself due to the brad centre and you end up with a stepped hole - for when you want the smaller hole to fit the flipper button, and the larger hole to recess the nut that keeps it in place.

[@theJmanStriketh]

Me too! Auger bits are boss for lower speed drilling, and the spurs leave a nice finish across the grain. If you use a brace you can relatively accurately get depths by counting turns. And the old ones aren't that expensive online or from the right thrift store/antique mall. I think they just don't fit into Adam's main style of work as well as Forstners do (metal machine shop, quick drill chucking, lots of different materials, larger holes, etc.).

For anyone else who has never read the manual for a DeWalt keyless chuck like Adam is using, they are designed to lock only once you rotate them slightly backwards. So turn the chuck clockwise until it seems fully tight, then rotate it backwards a couple of degrees and you will feel a click as it locks. A spinning drill bit will no longer cause the chuck to unlock and the bit to fly out.

But, these programs over time, have been removed from the school system. Thankfully, you mentioned kiwico. Now, I can share things I learned growing up, that my boys haven't. And thank you for reminding me that I must have a set of Forstner-Drill-Bits, or my life won't be complete. Like a combination of a hole-saw, a speedbore bit, and a spade bit all in one.! Makes a hole-saw just hugely inaccurate and archaic by comparison. Found a set on Amazon for $30.00.! YES!

[@MrPDawes]

The Matrix is working. Just got to the end of this video when Amazon delivered my wood working drill bits. Perfect timing.

In woodworking, the thing I've seen most people just not have any awareness of is the process of milling lumber. People seem quite significantly keyed in to the home depot, dimensional lumber process, more than the raw sawmill lumber style that hardwoods are more typically found in.

[@absalomdraconis]

I'd say that's understandable, given that "raw" boards just aren't as casually available as the "cleaned up" pine that normally gets used for home improvement stuff.

[@AxGryndr]

It's because the cost of getting into milling lumber is substantial. A quality planner and jointer runs on 220v which most homes are not prewired for. Depending on the location of your panel, running the wire is expensive. Additionally, you panel may not support any extra load. As you can see, the cost can quickly run away from what most DIYers can afford.

[@RadicalEdwardStudios]

@@AxGryndr The home gamer stuff is all 110v 15a compatible. Hardly high end stuff, but it exists and it works for low frequency usage.

[@AxGryndr]

@@RadicalEdwardStudios You are right, you can get a lunch box planner, like a Dewalt 733/4, that runs on 110v however they present a number of issues (snipe, underpowered, limited capacity, slow feed rate, etc). For someone that is running that small of amount of board feet, the price tag of the planner usually is fairly high compared to the cost of paying for S4S lumber at a big box store.

[@RadicalEdwardStudios]

@@AxGryndr There isn't always sufficient selection at box stores. That's the main reason people haven't given up on hardwood suppliers.

I just watched Adam talk about his tool and bits for 25 minutes.

[@ironwood1621]

Benjamin Forstner was born in Pennsylvania but migrated to Salem, Ore., in 1865, where he was a gunsmith until 1889. His knowledge of metallurgy, boring and rifling helped him develop the bit that was originally called the "Forstner Flange Bit" or the "Webfoot Auger." He patented his bit design in 1874

[@MrYukon2010]

One of the best (if not the best) introductions to drill bits I've encountered on YT.

[@Games_and_Music]

3:08 The Toolshed's version of a MAC-10, i love it! haha

[@ABH313]

Adam think you should start watching Project Farm. He has tested a lot of different products that you use. Like drill bits, tools, glues, and other everyday problem solving products

[@RataStuey]

25 minutes but Adam is such a great communicator of science and tools that this felt like 5 minutes

[@andrewstambaugh8030]

It's very worth mentioning that *stepper bits can save you from a really bad wrist sprain* when drilling metal, especially multiple layers of thick gauge springy sheet metal. The progressive and more circularly-supported stepper bits self support (= force not through you) and don't allow a sudden deep punch through. A regular twist drill is very inclined to punch through instead of cutting the last little bit of material and will suddenly twist the drill fast and hard. I as well as quite a few people I know have sprained our wrists this way. And I'm not talking about reckless people. I've done metal fabrication all my life, and knowing it was risky, was being really careful with a bit I thought was borderline size-wise. That was a 1-step learning process for me, when simply switching to a stepper bit would have saved me from missing several weeks of perfect motorcycle riding weather and I was lucky with no permanent ligament damage. If you are concerned about cutting speed, the tighter bits cut faster, while the wider style cut slower with less stick through.

[@MathMeansMore]

Adam you forgot about hole saws - the most underrated drill bit :(

[@GardensAndGames]

He did a separate video a while back about annular cutters, which are very cool.

[@konradzinner2255]

Please do a remake of the Camera-Stabilizer (possibly plus a vest or sth. to take the weight of your hand). Great Video!

[@bas8116]

I totally get your love for the forstner bits. I bought my first a couple of years ago to drill holes for fittings I had made from steel pipe ends that needed to be fitted into oak furniture I was building. It turned a job I was struggling with into something truly enjoyable. I agree with the cheap ones being fine, I have a set and none get used regularly but its great to have all the sizes available. I find the lower priced ones perform just as well, where they lack is in durability. I got a bit more expensive one in a size I use all the time. they are also great for fitting hinges.

[@rickybobby7276]

SDS masonry core drill bit is by far the coolest drill bit I’ve ever used.

[@thomasng6870]

@15:32 - that moment when I realized his tattoo is a ruler.

[@cemafor1006]

"It might be peculiar to have a favorite drill bit" Nah, Forstner bits are my favorite too

[@moonrazk]

I knew right away it'd be forstners, I've never even used them and they're my favorite.

[@barbnoren]

that's because we all know what's what

[@clemmcguinness1087]

This should be required viewing for anyone doing any tech class!

[@channelsixtyseven067]

Hello Adam, I was strengthening some IKEA cabinets with extra bolts. I used shallow cap-head inhex bolts so I could inlay them into the chipboard. The on thing capable of doing that, was the brace & bit. So I had a 60 year old brace, used a modern hex-drive chuck, in the brace chuck and a modern hex-drive Forstner Bit for cutting the hole. It produced a perfect, flat inlay for the cap head bolt to fit. _Nothing else_ would have worked. A brace and a Forstner Bit is one of the most under-rated tool combinations out there. It is almost impossible to get good quality Metric auger bits.

[@masone4718]

The predecessor to the spade bit (and auger bit) would more likely be the centre bit (the kind used in a brace)

[@gregculverwell]

They make a much nicer hole. I inherited a few from my grandfather.

[@DrYmath]

Hey Adam, I do a lot of work with electricians and the spade bit you mentioned does make a mess but its great at drilling a lot of holes quick, which comes in handy! The good ones have a threaded "point" to them, to help pull the spade into the cut.

[@AxGryndr]

I don't like the threaded tips because they pull into the material and can act as a wedge splitting it instead of drilling all the way through.

[@TroIIingThemSoftly]

Already knew all this stuff but somehow still sat through the entire 25-minute video. Adam has a knack for making just about anything interesting.

[@donaldevans5752]

Adam teaches as well as entertains , brilliant video , thank you Adam .

[@workingclassless84]

I've found freud forstner bits to be the best lower cost option. Also, learn how to sharpen your forstner bits you'll get years of life out of them.

[@chrisforgan731]

thats goes for any cutting tool

[@hhowell1990]

the first drill you were holding would likely be a chisel point twist drill

[@1pcfred]

It depends on the grind whether a twist drill has a chisel point, or not. You can split the points on twist drills and then they do not have a chisel. So just call them twist drills. Because that's what they are.

[@GadgetflashMinecraft]

Is jobber not the term he was looking for

[@ericspants]

I actually just bought a set of forestner bits a week ago and I LOVE THEM! Brad point bits are my second favorite bits for precision work. PREACH !!

[@Florkl]

I’m sure 3D printing wasn’t a thing (or at least was a much less accessible thing) when Jamie made his statement about making, but that is why I find additive manufacturing so fascinating. You’re able to leave voids in places that would be inaccessible if you were trying to remove them from a solid object. To say nothing of waste reduction.

[@PureRushXevus]

"deep *drive" ahaaa I see what you did there :p I was wanting to get a step-drill the other day for making holes, but a pretty basic one was like 30-40$ here in a local store.. surprisingly expensive, when an entire set from 1-14mm can be as cheap as 10-15$

[@RacerX-124]

I've been machining quite a while and had never seen nor heard of a Forstner drill. I'm going to add some to my box! I was hoping you'd talk a bit about TX drills too, I've been a huge fan of those lately.

[@mattsnyder4754]

You inadvertently described my preferred tool buying strategy. If you need it once, borrow it. If you need it twice, buy the cheap one. If you wear out the cheap one, you can feel good about buying the nice one, because it’s clear you use it frequently

[@mraymo1977]

Spade bits are great for rough construction work. Like when you have to run wire in the walls and you need a hole in your studs. Forstner bits are great for work where you need a very precise hole for a project.

[@JaccovanSchaik]

"That thing that I just did? Don't ever do that."

[@HotForgeChaos]

Do as I say not as I do

[@ponsaravanan]

I never had anyone explained that simpler to the point and very informative. needless to say Subsribed.

[@Jezee213]

Love Foresters man, so great, clean, and accurate! That gimbal is a work of art Adam, love it!!

[@johnm840]

Thought you were going to say split point and then Jobber. Nice review.

[@danielbender4327]

Adam, you didn’t mention the other awesome thing about Forstener bits…maybe because it’s too obvious? Flat. Bottom. Holes. I myself only learned about these bits because I needed to make counterbores in a wood project, and had no idea what tool I was looking for. Luckily, the fellow at HD did, and I can now say that I have seen the light.

[@d1663m]

My dad was a machinist for most of his life. He introduced me to forstner bits. They really are amazing things.

[@keeganpenney169]

Gotta say this is the most educational video for anyone I've ever seen come from Adam This is legit discovery channel content
