There's actually a 4th variation on these bits which has to do with the inside cutters. And because this particular innovation deals with the problem of heat that you referenced, its worth mentioning. The bit design I'm referring to has straight outside cutters (not saw-tooth) but has the inside cutters segmented with small gaps. These are found on the Colt Maxicut Forster bits. It sounds like a minor change, but the difference is heat build up is astounding. The Colt's are by far the best Forstner bits I have used.

[@nkosiakinlabi3135]

It seems these are no longer available as no one has them in stock

[@cmpoirot1]

To answer your question about twist drills, the biggest thing that you need to know before you drill is your material and your tolerance. For metals, there are situations where a standard twist drill will not give you the hole type that you want such as, sheet metal, and narrow tolerance holes. In sheet metal, regular twist drills will produce an oversize triangular hole. For tight tolerances >.005'' (depending on hole size and rigidity of drilling fixture) it can be better to drill slightly undersize and ream to final dimension. Reamers are better for this because they are designed to remove less material, so they can be made more rigid and will generally have a more refined cutter geometry. However, when drilling in wood there are very few situations where you would need to hold that kind of tolerance, so a standard 118* HSS twist drill will do the job in most every situation

TY for the discount. just picked them up! i had purchased a set from harbor freight years ago. i wasnt sure if i really needed a set of forester bits as a woodworker and i figured that set would get me by pretty cheaply. at the time i had no idea what was going to be involved in a half hand tool and half power tool set up. tldr is i found out very quickly that i would need quality tools and a lot of them!! thank you so much for making that easier. and a special bit of advice to anyone just starting out....always buy quality tools the first time. cheap tools are frustrating and you will almost always have to replace them anyway.

Forstner bits...my #1 woodworking friend/discovery in past 4 years. I have found that anything under about 12--14 mm diameter needs frequent lifting out and clearing otherwise the wood powder binds and jams the bit..great fun working out a way to extract it...... btw..the mediaeval torture thing..( it must have a real name)... apart from being lethal if not tightened up and fingers kept well clear....I use it to cut out wheels in 10--15mm plywood....going 2/3 way through and turning over for reasonable clean cuts. ......from NZ

[@tomalealso]

i used high speed drills on my wood projects only because I did not know any better, yes they tend to wander too much to make good clean holes. I used paddle bits and I knew about forstner bits but I didn't know about the small ones since the only ones i have ever seen was used by plumbers during rough in. I now have a set of forstner bits and a set of brad point bits for holes too small for forstner bits. I have a set of hole saw bits too but mostly use them for construction applications and not fine woodworking.

Been a woodworker as a hobby for 3 years, and bought some very cheap forstner bits from Amazon, they're not very good, they actually suck, been waiting to find some good bits for a reasonable price and I just couldn't say no.

Hey thanks for the realistic way you present your tutorials. it makes it so much easier for me being a relatively new comer to fine woodworking. Great store too.

[@labrat7357]

Thanks for the video. One important thing you did not mention about forstener bits and keeping heat to a minimum is having the correct peripheral speed for the most efficient cutting and least heat buildup.. I have seen very expensive bits ruined by inexperienced users not adjusting the drill press to a speed that is slow enough to suit the bit diameter and in a set like yours the smallest bits may cut best at 700- 800 RPM where as the the big 2" bit may need to be run at speeds as low as 120 rpm.. It can be a hassle changing the speed on the drill press for a couple of holes but it will extend the life of your expensive tools and prevent wood burning. All the best.

Normal twist drills make slightly triangular holes because the bit wants to dance around in the hole. Brad point bits are much better because the center point registers the bit and keeps it centered. I have never seen this be an issue in woodworking, but have seen it cause issues in tool and die making where precision is essential.

[@katzmosestools]

Great info thank you

[@timothyball3144]

[@niekgalle948]

Drill bits often cut triangular holes. By drilling a smaller diameter first and finishing with a bigger drill sometimes solves this issue. HSS drills are flexible compared to carbide drills that are not flexible and tend to shatter alot quicker if your part isn't fixtured.

[@chrisjordan4210]

No, drill bits don't drill round holes there is always some eccentricity. There is an old engineering series of videos from MIT by Erik Vaaler where he describes why there is no machine capable of drilling a truly circular hole, but I don't think it should worry us woodworkers - hell the stuff moves all over the place as soon as you go near it!

[@MrConminer]

Just go look at wood after work out and it bends because of the changed moisture content in the air 😂

[@andylevine4018]

solid carbide Split point drills will make round holes if properly chucked in a collet and the workpiece is held securely.

[@mikecurtin9831]

Regular drill bits don't cut round holes in metal, either. They also usually cut a few thousandths of an inch oversize, which they share with Forstner bits. When working in wood, the sizes are usually close enough. When you need a really round, precise-diameter hole (I'm talking less than .001" tolerance), you drill slightly under-sized and follow with the appropriate reamer. Best accuracy, for position, size, and roundness is a boring head.

[@carterscustomrods]

Great video. Just found you today... and... well.... it feels like home.

[@ericdeguilo1181]

Just got my apron!! She’s a beaut Clark

[@timothyball3144]

I have often drilled "triangular" holes in thinner metal when drilling by hand or in a drill press when the material isn't clamped down. I think there is relative movement between the bit and material that causes it but I have not figured out why it's triangular. Don't know about wood.

[@broken_font1881]

I just drilled three holes into a sheetmetal fan cage yesterday because the motor mount screw had teared out. After drilling the holes I noticed that the holes were pentagon shaped and I was mildly surprised. Doesn't matter though I just hammered in three threaded insert rivits and called it done 😎👍🏻

[@thenationdecides7404]

I think that’s where the centre of he drill isn’t securely located (say your pilot hole is too big) and so it essentially just bounces around. Maybe...

[@gordonmckenzie2982]

I was schooled that after drilling through metal one should use a reamer to accurately size and make the drilled hole round - when required for a bearing or alignment use. The theory was that each flute of the drill would grab intermittently so that the drill would pivot on the end of the flute rather than pivot on the point of the drill. In this manner the drill would tend to transcribe a shape based on the number of flutes + 1 rather than being perfectly round. The more slender the drill the greater the affect.

[@broken_font1881]

@@gordonmckenzie2982 that's a nice explanation as to why this occurs. Luckily for me the operation didn't have to be perfect :D

[@bret_Lambky]

Regular 2 fluted drill bits have a tendency to not always provide a perfectly reamed diameter hole. An option would be a core drill. Four flutes precision ground! I have always been pretty successful using those!

[@stevemitchell1265]

I would encourage you to look up the patent that Benjamin Forstner filed. It gives claims, one of which was a bit that would follow it's own hole even if you were drilling a partial-diameter hole--and stay straight. Before that there were augers that have 1 tip per flute scoring the wood ahead of the planing cut that removes the majority of the material. he added a gimlet point instead of the screw point used on augers as well. As a toolmaker, I have used about every variation of these bits manufactured today, and whenever you vary from his original design of a "knife" like ring scoring the material in front of the planing edge, you lose on the feature of being able to drill a partial hole, and/or the feature of drilling a long straight hold (such as in the manufacture of buttstocks for rifles, which is the reason he came up with the design in the first place). Any variation such as mulit-spur bits, wavy rims, even tapered rims to reduce heat or increase manufacturability, compromise the features of the patent and should find their own name instead of naming them after a man who invented something different than what they are making. I also take exception to your statement that the spurs and the planing edges are the same length. They are not. Forstner bits have the knife edge that scores the wood about .006" to .010" ahead of the planing blades to prevent tear-out that occurs when they are not that way. These bits create a lot of heat both from the slicing of the knife edge rim and the outside diameter being a straight wall that is essentially rubbing the holes sides while cutting. Therefore they have to be run slower than a fluted drill bit. Then heat is much less a problem. Your video of them running looks way too fast and I would bet you get a lot of heat that way. I didn't write this to attack you or your video, I just want to point out some important things about these bits and their use.

[@ThisTall]

I just bought a $200 14pc forstener bit set from LeeValley I’m SO disappointed with. They had 3-4 cheaper sets but I opted for the best. The scoring blades are so proud of the cutting blades they take to much pressure to use by hand. They’re drill press only.

If, as the CMT website says, these bits are normal tool steel, they will be very vulnerable to damage from the inevitable heat build-up that comes with the wider (>1/2") diameter bits. You buy a relatively inexpensive set like these and end up replacing them one at a time. You can learn this lesson, or skip it by paying the price (about 2x more) to get Forstner bits made of high speed steel.

Jonathan Katz-Moses I had purchased a set of Irwin Forstner bits but have been hesitant to use them for 2 reasons, well questions really. 1. I noticed a considerable amount of "wobble" on my drill press and the resulting hole was far from round. Is that something I can fix by lowering the speed of the drill? Which kind of leads into 2. Should I be using a low speed for forstner bits? PS the apron is awesome will be sending the photos to your social media as requested.

I'm a super novice woodwork enthusiast. How novice you ask? Well my "workshop" has the most basic work bench (left from my grandpa who was a metal worker) with a a metal worker's wise. As far as tools go I'm a proud owner of battery powered drill, some twist drill bits and a set of chisels (probably dull). Of course there are screwdrivers, hammers and wrenches... And given that my shop is super small, a table saw is out of the question, as is the planer. Now I'm eyeing a compound miter saw so I can for the first time in my life cut a piece of wood straight. Oh yes, I have no orbital or track sanders or a router.. These will come with time since they don't take up too much space.. But what scares me the most is the fact that I have to learn from tutorials and YT videos and there's really not a lot of content for a novice like me. I would rather have somebody by my side and teach me the basics but it is what it is... Anyway, I have a lot of money and time to spend to reach a level where I could create stuff I would be pleased with.. The first project I'm gonna start working on soon is the basic mount for drills and angle grinders, together with a place for various drill bits.. The next project (that's still in my mind and far away from becoming a real thing) would be some kind of a stand or a holder for my knife collection.. My God, how will that turn out I'm scared to think off..

A hole that is not round? 1. Improperly sharpened drill bit as in the point is off center or one edge is ground at a slightly different angle than the other. 2. Bent drill bit. 3. Loose or wobbly chuck. But an old helpful hint taught to me by a machinist is to drill your hole with the next size smaller drill bit then switch to the one you want and use it to chase out the hole.

[@thomassutrina7469]

Hand sharpen brand new drills that have never been sharpened by eye. Can actually do a very good accurate job if you do it often enough. When the box of drills has 1/8 that are bran new you get good at it. The center edge is perpendicular to the axis. It is where the two edges that are sharpened meet. It is not a centering feature which is why drills wander without a center punch diameter larger then this flat. You can see the drill wiggle the flat meeting point of the two edges is not centered on the drill. Your cutting at two edges 180 degrees apart so if the angle of the cutting edges are not the same but they are centered the drill will still wiggle since the force on one edge is different then the other. Wood adds another dimension since wood has grain. The force need to cut with an edge of a plane or chisel changes with the relationship with the grain. A drill has a cutting edge and experiences the same change grain relationship. The more force downward result in greater twist forces from the two cutting edges and if uneven will bend the drill. So to cut a round hole go slow until the wood helps resist bending of the drill.
