FTG USA Wood Countersink Drill Bit Set Maximum Torque, 10, 12 with Woodworking HSS Tapered Bits Secured with Pin and Hex Wrench (1/8" Allen Key) 5 Piece taper bits (without Depth Stop Collar)

The best I’ve found

Arrived safely, but when I tested it on hardwood, it got pretty hot. Which might be an indication of it getting dull faster

De verdad me gustaron mucho. Las brocas están muy bien afiladas y la pieza para el avellanado hace un excelente trabajo. Me gustó la posibilidad de recorrer la pieza grande a lo largo de la broca para ajustar la perforación al tornillo lo mejor posible. Al principio tuve la impresión de que las brocas eran demasiado gruesas, ya que usas cualquier broca del kit se entiende por qué. El vástago hexagonal de ajuste rápido funciona súper bien con llaves de impacto pero es demasiado ruido, prefiero usar el taladro. Estoy muy satisfecho con el producto.

They drill very well and screws grab nicely in the tapered pilot hole. Excellent product

Nice bits for drilling and countersinking at the same time. The tapered drill produces a hole that uses the whole screw to grab wood, not just the upper sides, and with the drill shaft engaged in the wood, the countersink hole doesn't chatter and looks great. The adjustability of the countersink head also allows for different length screws, but really short screws can be a problem - long screws just require drilling deeper with a longer bit after starting the hole. Extremely useful item, a real time saver, and seem to work well in pine, plywood, and MDF. Haven't tried them in hardwood yet, but don't anticipate any problems there, just clear the chips more often. I took a scrap piece of 2x4 and drilled holes to store the bits - use one size up, so the #6 drills a hole for the #4 bit, etc. They hold nicely and are easily accessible.

Sawthese on the wood whisperer ordered them, what a dream to work with the design is great.
