🔩 Optimized High-Speed Flex Bellhanger Bit Review

I have a lot of long flexible drill bits. This bit is fine, it needed sharpening to work properly. It also lacks lateral play, making it almost impossible to control the drill. But I sanded the gap a bit and sharpened the tip and now it cuts pretty well. Shaft flex is good and has enough power to cut through nails and even deck screws. Few drill bits can go through a deck screw. But the sharpness and geometry of the tool differed from the most preferred long flexible drills.

. The 1/2" spiral portion of the drill stayed sharp for the 80+" Cherry wood I drilled. But because it has such a small flex shaft I would only use it to widen the smaller straight hole pilot, otherwise it will follow the grain of the wood and deviate. If you have a situation that doesn't require a straight hole, that's fine. If you want a straight hole, I would look for a long drill bit with the shank slightly smaller than the twist bit portion.

Drilled 13 holes in 2" to 6" thick jaw without much trouble, although hooked 6" jaw a few times (4 pins). ) and since I've already gone through a bolt I can't move it to widen the hole so it takes a forward/backward movement to get through. I then attempted to drill a hole in the 10" thick maple wood, for which it didn't stick well and ended up breaking, see photo, and I had to split the wood to get the drill head out. so heavy but when you look at the break it's clear it's glued and not welded
