Nice bits...
These are good replacement bits... a bit brittle should you hit a screw or something, but the ones I had lasted quite a few years of moderate to heavy use during boat building.

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.
