Your cart is empty.Bosch Hex Shank Screw Pilot Bits drill precise, clean pilot holes in wood, plastic and composite materials. Used for fast countersinking and counterboring in one operation, these pilot bits drill countersink pilot holes for flush screws. The drill bits are replaceable. The screw pilot bits provide adjustable countersink depth with an Allen® wrench. The hex shanks are designed for reduced slippage, and the shanks fit corded and cordless drills. Ideal for drill press use.

I picked up these bits for a particular project with poplar that needed a countersink. Admittedly, this is the first countersink bit I've worked with. Worked with very little resistance and made a perfectly sized hole for my #8 screws. There was a little bit of cleanup needed around the hole before paint but otherwise, worked nicely. I can't speak to how well these will hold up or in harder woods but for an occasional project or someone just getting started, they work well. I only wish that they'd include a storage case but at this price, it's hard to complain.

Overall I think Bosch does a good job with their products and these work well but be careful with them. Was using the #6 bit to countersink some screws into a pressure treated 4x4 to make a circular saw jig for joinery and the bit broke working on the second hole. I figured that’s what I get for using it on a big piece of pressure treated lumber. The real frustration I’ve had has been after replacing the bit it doesn’t want to adjust or work the same as when it was bosch’s bit. Overall cool piece.

Solid construction, buts were tight upon arrival so no issues there. Worked great for the average DIY kinda guy like myself, though I'm sure there are higher quality bits out there, I feel like these are great for the price!

I had finally worn out my 40+ year old drill/countersink bits and picked these up. They are working great, and appear that they may well last longer than I will.

Haven't worked extensively with them and only ever having used the smallest on my job (carpentry), this saves me having to swap from a pre drill size but to a countersink size bit.Also compared to a regular countersink size bit (¼" / âµ/16 or so) it doesn't result in tearout around the holes. This is with both soft and hard woods, pine to teak. 4 stats for longevity because well I've only had them for so long.

Works well. I used two of the bits quite extensively, and they so far hold their sharpness well.

bits are sharp enough but collar doesn't stay on (even when I over tighten). would probably not purchase again

Aguanto las perforaciones y excelente material y excelente filo y no se rompió la broca como los dewalt.
