Bosch Professional 2608595498 Selfcut Speed Flat Drill Bit, Hex Shank, 32mm x 152mm, Blue

These bits make drilling a breeze. I drill hundreds of holes a week with these bits and they just plow through ! Last ages and hardly ever blunt ( mind the nails though haha )

I was working blind cutting through a joist that was set way back in a timbered ceiling. Only access to ceiling cavity was from my garage. Bosch tool located and cut through heavyweight joist in around ten minutes

These are a mixed bag. The spades are sharp and the flared ends leave a great finish on the edge of the hole. The hex shank is a great fit for either an impact driver or battery drill. What I didn’t appreciate is that the pilot guide has quite a course thread, and this drags the bit into the wood very rapidly compared to how I usually feed in. You can get away with this for softwood, but it’s too aggressive for hardwood or composites. On a battery drill you will get better results flipping the gearbox over to your lowest speed/highest torque. Normally I run spade bits flat out so the draft blows away the chips. So not what I’m used to, but not a disaster so far.

Work really well especially if used at a slower speed. Stay sharp for ages as well.

I swear by these very easy cut pulls itself through with no effort

Item photo doesn’t match description, very misleading.

Brilliant spade bits. Strong and even able to use in impact driver

very good wood bits for drilling though joists - from electrician
