Fed up with waiting for an extra long series 8mm HSS drill bit, on a whim I bought a Bosch Multipurpose bit from S'fix as I was passing:

Well impressed with it going through timber, in fact pretty effortless and little break out on the reverse side. Never trusted anything "multipurpose" before but it's great. Still wondering HTF something that looks like a masonry bit can drill through wood!

I still wonder how the cheap tile drills that have a flat chissel like blade can actually drill a perfect round hole so effortlessly in ceramic tiles.

I'm on my second set of those - they had them recently reduced from £11 to £5 for a set of 4. http://www.screwfix....-set-4pcs/95958

First set lasted 3 years and the only thing they didn't like was reinforced concrete lintels..!!!

Solid bit of kit and made life very easy

Those pointy, bullet shaped flat things? I've got a couple of sets up to about 10mm. Always very satisfying seeing them go first through the glaze then like butter through the tile. Never cracked a tile yet.

Tungsten Carbide tipped tools are pretty impressive if they are sharp. I discovered by accident that a TCT wood working router bit will machine cast iron.

If only they would make them a decent length. The times I want to drill different materials is when drilling a timber framed wall, and I end up blatting through the wooden bit with a masonry drill. I'm talking of needing a set 10mm and above 400mm long.
