As I was installing a class 3 Hitch on my Kia Sorento I discovered the four threaded holes in the bottom of the frame rail were bunged up from rust. One trip to Ace hardware to buy a n M10 by 1.25 thread pitch tap, a tap handle and cutting oil saved the day. I followed the instructions this gentleman proposed. In between tapping the individual holes I used brake cleaner to clean off all the shavings on the tap before using it for the next hole. The supplied hardware now has attached my hitch to the frame because of this video and my purchases from Ace hardware. Thank you Hagerty for uploading this informative video.

[@autka_me]

Just my two cents on the subject, that I've learned the hard way over the years: - T-handle if you can fit it in is best way to drive the tap for two major reasons: it's easier to see if it goes straight and it's harder to break the tap because you don't apply side force like with ratchet. - It's handy to have some kind of small machinist square to check if you starting straight. Especially for thread that will go deep into the element and you don't have/cannot use drill press with spring loaded tap center. - And as much as power-taping seems appealing because it's fast and almost effortless - sometimes it's the fastest way to spend next two days trying to get broken tap out ;)

@@dougrobinson8602 haha Been doin it for a little bit. A chisel and hammer can save you if you’re really careful and have the time. Really careful.

[@dougrobinson8602]

I use a drill press for tapping whenever I can. My tip is if you have a cheap belt-driven press, pull the belt off, and turn the drill press with the belt pulley above the drill chuck. That way, you can back the tap and feel if the tap is taking too much torque to turn. Don't forget to unplug that drill press before you touch the belt or pulleys. Always,always, always wear goggles or a face shield when tapping. When a tap shatters, it will throw tiny and sharp shards of extremely hard metal. Nice video with great explanations of thread dimensions.

[@madeleinesutherland1623]

Ha! I'm in the lab construction business rather than the car business, and this video was very helpful information! You never know how many ways the content you put on KZbin can be useful.

[@LloydGM]

Perfect for amateurs like myself: clear, short but detailed, and to the point. I really appreciate the great advice you worked in, too. Many thanks! PS I especially appreciate talking about threads at the beginning. That helps we who want to learn more than just how-to steps. /cheer

[@MrTexasDan]

Great how-to! A couple of tips from an ex-machinist: 1) Like Davin says - chamfer your holes, preferably out to just over the major diameter of the thread. This makes for a clean finished look, and prevents sharp threads above the surface which will pull out. 2) In a drill press, instead of center punching, use a "center drill" to start the hole before drilling. This bit will locate the hole, and provide the chamfer in one operation.

[@davidrandall271]

This is going to sound grumpy, but it seems there just isn't a lot of knowledge here. Let's be clear...you use a spot drill for pre-drilling, not a centre drill. A centre drill is used for putting a centre in for turning between centres on a lathe, it is bad engineering practice to use a centre drill for a drill. Also these dies here are die nuts, only suitable for reclaiming threads as the rake angle is typically negative. Split dies are used for cutting thread.

[@MrTexasDan]

@@davidrandall271 Yes, of course you are correct, it does sound grumpy.

[@4thGloryMonday]

heres a tip for tightening a drill chuck when the bit spins in the chuck, tighten chuck in all three holes then back to the one u started with

[@johnmilner7603]

I always tighten 2 hole and that works for me.

[@allogan8152]

Also, don't bottom the bit into the chuck. Put the chuck grips on the end of the drill bit, 1/4" or so. When they heat-treat the bit in the factory they hold by the end so the metal there is left softer and the grips will grip better.

[@richm.1583]

[@kar4tube]

Thank you! Very thorough and extremely helpful. Seems I've always had a working knowledge of basic tapping concepts and steps, but needed a deeper level of detail for my current challenge. I'll be putting your guidance to work on a BMW differential cover plate bolt hole. Was just checking the torque specs on the cover plate earlier this month and discovered one of the bolts was spinning freely. Turns out at some point in the car's history someone had half-assed a helicoil on the hole in question. So, I'm in the process of conducting a thorough thread repair - properly! 👍🏼

[@directorgtr]

Love the straight forward teaching approach. Well done and I've subscribed.

[@PMD_Bill]

I use a center tool in the chuck and use that to line up the tap in a tap handle and hold it straight. I have never thought to put the tap directly in the chuck of the drill press, but I'm going to have to try your way. :) Also, at most hardware stores you can buy the drill and tap packaged together.

[@zsozso411]

One thing I’d like to add is that the best drill bits I’ve ever come across are cobalt drill bits, they cut through metal with ease and rarely break. I use German made HSS Cobalt drill bits but you can buy Irwin ones on line as well or whatever as long as it’s cobalt.

[@ronfox5519]

True. And get them- at least the smaller diameters -in screw machine length split point. Another great option is sheetmetal bits, particularly as pilot drills or hole starters. The double enders are a better value.

[@KrautSpaceMagic]

i drill and tap holes all day every single day for trucks that cost twice as much as most peoples homes, here are my 2c on this specific video -always pilot drill your holes with a 1/16" or 1/8" drill bit, your holes walk a lot more than you think -try to use a chamfer bit instead of a deburring tool, it creates a more consistent and clean edge -T handles suck to start a thread straight and they always slightly gall the first few threads on the way in or out while trying to align itself -electric drills are actually very good to tap holes with, it has enough height and vision over the drill bit and tap to see how straight you are. and with a nice tighten on the drill chuck the tap will often spin in place without cutting before it breaks the tap. -mechanically rigid tap setups (like those sockets that run off the square drive) you should be VERY gentle with, the moment you start putting torque on it in a setup like that, thats when taps break -you can NEVER have enough lube, ever -clean your tap after every single hole

As a Tool and Die Maker and have tapped many thousands of holes I can add a bit (get it, a Bit lol). I like that you mentioned pre-drilling. Many drills don't cut an on-size hole as the chisel tip might not be well/poorly sharpened. If you pre drill, the hole's size will be more accurate. Also, have a look at spiral-point taps for through holes, and spiral flute for blind (you can use spiral point for bind but you have to pick out the swarf) . I tap all of the time with hand drills and drill press and never stop on the way in. Run it in and run it out. I hope this helps.

On the drill press you can also just turn the chuck by hand. Great video by the way.

[@mv4ago]

That's exactly how I do it. Start the tap in the drill press turning the chuck by hand, this keeps the tap perpendicular to the workpiece, then finish off with a hand-held tap wrench either T bar or chuck type. I started tapping holes 47 years ago and I've probably broken about 10 taps in all that time.

[@friguy4444]

Thank you I learned some good things from this video!! A great tip to have had in this would be that if you're tapping on a cylinder head or something where you don't want the shavings to get into the engine or someplace while you're tapping to use some thick grease on the tap and around the tap to catch the shavings so they can be removed before they fall or fly into the engine or area you need to keep them out of. It works!

[@spaceoddity2485]

Yes, good tip. I have heard of that before. The grease from the suspension grease gun is good.

[@ickess]

I have done everything in my power to remove a stripped Allen bolt from the engine on my motorcycle. I am anticipating having to drill the head off to remove the component. Then hopefully be able to grab the rest of the bolt with pliers and slowly back it out, but anticipating also deadbolt, possibly snapping and they having to your truly and tap it very helpful.

Thank you for the clear demo on how to drive the tap. I bought the taps, they didn't have the handle, it didn't occur to me a drill can be used until I saw you do it. And the hardware store sells each tap separately and no indication what drill bit to use for a chosen tap. I guess it's trial and error at first until I learn what to use with what.
