Rated 3 out of 5 by from not all of these perform well I purchased a full set of sizes of these to save space in toolbox. I can see HUGE variation in performance and reliability in these drill bits. I used 8mm and 10mm A LOT, and also to drill in lots of different materials. As a matter of fact I bought two 8mm "just in case" and approx a year later I'm still using the first bit. HOWEVER... (now to talk about the bad side) The smaller size bits, ESPECIALLY 4mm (hence I'm writing review via this particular bit size) are worse than bad... They are BAD bad... Today I wrecked yet another of these drill bits, used a brand new bit, and I drilled 6, that is SIX holes, in approx 4mm thick ALUMINIUM... And obviously I've taken extra precautions having so bad experience with these over past year, drill in slow mode, material firmly resting on chunk of wood, etc... Summary: - brand new 4mm drill bit - 6 holes to drill - 4mm thick aluminium With each hole I could clearly notice bits of tungsten carbide (or at least I think there are TC tipped???) tip cracking away... I'd gladly post pics, however I can't see option in my browser to add pics into the review. Overall, drill bits @ 4mm are lacking a lot, I'd score them 1 on 1-10 scale. 4mm+ to 6mm I'd say 2 or 3 on 1-10 scale. Ending with 8-10mm bits with 10score, can't fault these! I love the idea and "theoretical" performance of these drill bits, and I'd love to keep just one drill bit of each size in my toolbox to use in ANY situation, however Bosch needs to improve on these. Simple as. Idea is great, but manufacturing technology is just simply not there yet...

Rated 5 out of 5 by from Exceptional Best drill bits by far. They drill through almost anything and you don't need to change bits. Tiles, brick, 'steel, plastic, wood. YOU NAME IT.

Rated 5 out of 5 by from Bomb Proof......... HI, I bought one of these to replace a very basic one I had which managed to drill 4 4mm holes in concrete steps. After the fourth hole it was gubbed. I went to Screwfix and got the Bosch Multi-Purpose 4mm, sadly they only had one at the time, but hey, I didn't need to worry as it dealt with the other 33 holes I needed to drill in the concrete steps as if a knife through butter. I was plating concrete steps with decking boards to match up to the wooden deck steps leading on to them, so this drill bit was also able to drill through the deck board with ease also. Just wish I could afford a full set of them, they are brilliant, and highly recommended. Ian
