Extra dlouhé kuželové vrtáky do dřeva

Needed to run wiring through a 10-inch stud wall and my old bits barely made it halfway. These extra-long tapered ones reached all the way through with no wobble, and the conical tip started cleanly without wandering on the surface.

I've burned through plenty of standard bits trying to reach deep spots in framing timbers, and these extra-long ones finally get the job done without swapping out mid-hole. The taper keeps the cut clean and steady even at full depth, and they haven't wandered a millimeter. Just wish I'd bought them

The conical taper really bites into the wood right from the start, so I didn't have to fight the bit to keep it centered. Got through a thick oak beam in one clean pass, no wobble at the end. These are staying in my main kit.
