Bosch Flat Wood Drill Bit Hex Shank 25 x 152mm
Good product from Bosch. Hardwearing and eager to work its way through tough wood.

Have been using plain basic flat bits for some years, NEVER again after using this flat bit went straight through wood, plasterboard etc... Like butter. Never going back to plain old vanilla bits again.

The packaging claims this cuts 10x faster - which is ridiculous, its more like 20x faster!
The screw tip really draws the bit through whatever you are cutting.
The "exit side" of the cut is extremely neat, you'd be hard pressed to see which side it was drilled from.
The only downside is my Hitachi 18v 1.5 battery drill runs out of torque at times.

These bits are insane!
I have a couple of these bits and they really are insane! They're like a bloody piranha! As soon as they touch the wood, they're chewing through it in seconds.
I actually have to hold the drill back.
As an example of how efficient these are, I cut a 25mm hole though an old 10cm thick floor joist with a normal flat bit and it took ages, burnt and lost it's edge. Another hole with this new bit took 15 seconds and barely generated any heat at all.
I have a 40mm on also and it's just as good.
