Set of metric HSS drills, TiN coated, 1,5 – 10mm.
Unusual grind, with a point angle around 140 degrees, facetted clearance angle and precise web-thinned point.
I've drilled black mild and silver steels with the 4mm. size, and it worked well with low thrust required and even curls of swarf from both flutes. The lip looked the same after as before, and the plating was still there.
As far as I can see, a decent small set of drills for £3.99.
