30-PIECE DRILL SET 3/32” SHANK Ordinarily, drill head size & shank size match. The problem is that micro-motor tools, Dremels & flex-shaft handpiece collets accept standard sizes.

A typical 3/32” collet only accepts a 3/32” drill. So unless you need a 3/32” hole you are out of luck. Finally, a mini drill set that fits standard 3/32” collets! Tough HSS steel & precision twist bit grinding hold up to wood, mild steel, stone. Set includes 30-precision made HSS steel mini twist drills, 2-each of: .5mm – 2.3mm (2-each of: .5mm, .6mm, .7mm, .8mm, .9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2mm, 2.3mm).
