Cobalt Drill Bit 4mm (2 Pack) is rated 4.4 out of 5 by 62.
Rated 1 out of 5 by from Use for metal only Needed a solid 13mm drill in a hurry couldnt get a wood drill. Drilled into a piece of timber. Tip snappes off within seconds. Was told these drills are purely for metal and should be used with lubricant. Was given a refund. Thanks toolstation for not quibbling.

Rated 5 out of 5 by from Excellent and stay sharp if used properly I used these drill bits to drill across the heads of some high tensile steel bolts so that they could take lock wire. Us them only in a proper pillar drill and on the SLOWEST speed setting. If you try to drill quickly, the drill's cutting edges will skid rather than cut into the steel; they will overheat and go blunt. Used properly they work very well.

Rated 5 out of 5 by from Great value I didn't expect much from these and they are so cheap but I drilled about 10 holes through 15mm steel at full speed to check the durability and they are still as sharp as when I started

Rated 1 out of 5 by from Didnt work! Bought it this morning. Used it on 5mm thick steel for 10 minutes and all it did was make a shallow dome. I then tried a 5mm hss drill bit i had and it went straight through! Taking it back for a refund and will try the 13mm bosch one from another big supplier up the road for half the price.

Rated 5 out of 5 by from Good value sturdy drill bit Was having problems drilling through hard steel with normal SDS drill bits so bought this and it did the job perfectly, no problems at all.
