Drill sets in metric sizes
Although imperial drill bit sizes are the most common in the USA there will be applications which require metric drill bit sizes.
We have two metric drill bit sets for drilling harder metals.
19 piece set
Our 19 piece cobalt drill bit set comes in a sturdy plastic box. Sizes range from 1mm to 10mm increasing in 0.5mm intervals.
If you need to be able to drill various hard metals this is probably the best drill bit set for you.
At 5% cobalt these bits will drill hard metals including stainless steel.
Drilling hardened steel
Watch this video of our metric kobalt drill bits in action. Here they easily drill through a hardened bolt. Note the slow drill speed and the use of a cutting paste.
