Type of drill to get?

[oscar21]

Using an impact for joist drilling is best when using the Bosch blue self pulling spade bits.
It's noisy yes, but almost effortless.

I've tried those bosch bits but once the threaded bit goes blunt on the end (which is quite quick) the bit is useless. I use the Dewalt extreme bits which cut just as quick but can be re-sharpened a good few times if you have a bench grinder in the van.

I have the Bosch screw in flat bits too… Used them with a brand new dewalt combi…. 7 holes, and the drill went up in a puff of smoke.
Got a replacement, no quibble.


Reading back the thread, there was a few suggestions for an impact…. Don’t!
Then you won’t be tempted to use it for tightening up mcb terminals!

Bought a set of those Dewalt extreme flat bits for about £11 in a Toolstation offer. Can't fault them as spade bits go.

I like that we can call them that, without fear of reprimand!

Spade?

How do you confuse a plumber?

Show him three spades and tell him to take his pick.
