Tapered drill bits
Great product. The only drill bit I use when pre-drilling for screws. Makes for a very secure fastening. These are secured directly into my drill chuck not with the driver. Works well.

I love it. Use almost every day. Wouldn’t be without it.
Great product for pre drilling at angles or end of boards so the board doesn’t split.

Perfect replacement
The tapered Inst bits are very sharp and work well but are brittle so occasionally you can break the tip off one. If it is not too much missing you can grind a point back on to it but I needed a new one and this works perfectly.

Its all I will ever use
This is all I have used for the past 10 years and there is nothing else in my opinion that comes close to help u set a screw without splitting the wood when setting a screw.

Will these replace the bit in the avenger pro set ?
Ian P on Aug 24, 2016
Does the taper go the length of the bit? If not, how far?
Howard M on Jul 16, 2017
BEST ANSWER: The taper extends the length of the cutting portion of the bit. The smooth shank is not tapered.
What size is countersink for #10 or #12 screw?
Jan N on Aug 12, 2019
BEST ANSWER: Measure the out side diameter of the screw then match to the counter sink diameter
is there a flat spot on the shank to keep it from turning?
