مجموعة مثاقب، 19 قطعة، قياس متري، فولاذ كوبالت

Finally a drill set that covers every size I actually reach for, from tiny 1mm precision holes up to the common 10mm ones. The cobalt steel coating cuts through mild steel noticeably faster than my old high-speed bits. This gives me exactly the right bit for each job without having to improvise.

Wasn’t sure I needed a full 1mm to 10mm spread, but having every size in that range in one indexed case has saved me so much hunting. The 6.5mm bit chewed through a steel bracket without wandering, and the cobalt finish hasn’t shown a single chip after a dozen holes.

The cobalt steel bit through 5mm stainless like butter, no burning or wandering like my old HSS set. Having exact metric sizes from 1 to 10mm means I don't have to guess with fractions anymore.
