DeWalt 4mm Extreme 2 HSS Drill Bit Pack of 2 is rated 4.2 out of 5 by 34.
Rated 5 out of 5 by from Essential I have used these drill bits to fix into metal lintels. Still on the original after fitting 100 venetian blinds and still going strong. Typical Dewalt quality :-)

Rated 1 out of 5 by from Blunt... I bought these to drill through my steel lintels for hanging blinds! After 6 holes of light pressure whilst drilling on a low speed the bit is blunt and now useless? Blunt after 6 holes isn't very good i feel, onto the 2nd bit and i still have 21 holes to drill, i don't think it's going to end well?

Rated 5 out of 5 by from Excellent drill bits. Bought these bits mainly for drilling through aluminium. They perform flawlessly - like a knife through butter.

Bought these for when we put our new metal shed roof on, having to drill into a seriously heay box section i didnt have faith in the self drilling tek screws so used a 4mm drill bit for a pilot hole, drilled through like a knife through hot butter, great stuff and still have life in them now

Rated 5 out of 5 by from Great product I would highly recommend these drill bits. I had been trying to drill through some metal with cheap bits that kept snapping. I bought these and sailed through the metal with ease and without any bits getting snapped.

Rated 5 out of 5 by from They are the best Drills These are the best drills for cutting holes through wood into sheet steel, Would have been better if Chelmsford Branch had completed my Order online. Had to make 2 trips which pushed up the cost regards PFG

Rated 5 out of 5 by from very impressed, talk about a drill bit ! normally when drilling cast iron or unistrut, i snap 4mm bits like anything. Not these Dewalt ones, still using my first bit, others go blunt, not these. very impressed...
