Cobalt Drill Bit 6.5mm (1 Pack) is rated 4.4 out of 5 by 70.
Rated 5 out of 5 by from Slow & steady: Cobalt is better cutting that HSS Cut like butter through 10mm steel. Managed 4 holes successfully because we cut too fast. The next lasted longer and enabled us to completed the job. Slow sped, oil and a hole punch are vital. Good price and readily available!

Rated 5 out of 5 by from Great on Stainless steel Bought these to drill through 3mm stainless steel. Had previously dulled 3 or 4 HSS bits to drill one hole so tried these. Went through the SS in no time with one bit. Great price compared to other DIY stores.

Rated 5 out of 5 by from Wish I found these sooner After 3 days trying to drill 1 hole through 1 inch thick steel and about ten drill bits I came across this cobalt bit did the next ten holes I needed done in about 12 minutes fantastic

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
