I would rather have a square for use in regular tap wrench if I decided to hand tap. The shanks are nice and long. and it looks like a quality tap. But I can buy the highest quality long reach metal taps for much less.

I use soft wax when tapping wood. it helps avoid tearing the fibers, and seems to cut them better. But yes, metal against wood will eventually wear down. Crappy metal threads more so then smooth threads, so the quality of the screw makes a difference. I have been doing threads for years w/ no problems. I find it easier than inserts which I find to lift a dimple around the insert too many times. Even when pushing down hard in a drill press to keep the insert in straight and manually tapping it by hand in the drill press (belt off). I still use inserts too, so no hard rules. -- Jeff --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Threaded inserts are, well, threaded into the wood, after all.

A bolt and or screw does not thread well into soft woods or plywood and last with repeated assembly and disassembles. I buy these things 20~50 at a time in lengths up to 1.25" long and they receive, in my case, 5/16" bolts. And FWIW I have never had one fail. I used 8 inserts and 8, 5/16"bolts to hold a commercial airplane display together. This display is used all around the world and is disassembled and reassembled for each convention that it is used at. I have been told that this display had been taken apart and reassembled about once a month for the past 4 years. Naturally if you use the wrong part for a particular application it is likely to fail. By the same token if I had simply threaded the display with a tap and not use a threaded insert and bolted it together it would not have held up with 50 plus cycles. |

I want to say acme. Wood tap/die units for brush instruments - shop
brooms - are tapered. Metal threads are typically to fine for wood. Some of the x8 or x4 are not far off. Inserts fit into hard wood in a specific threaded hole.
