Ruko Step drill HSS, Size 12, 6,0 - 32,0 mm

Step drill made of high-performance high-speed steel. Ideal for steel, cast iron, non-ferrous and light metals.

The deep ground and spiral flute offers absolute smoothness and high cutting performance. In particular, non-breaking chips are cleanly removed as with a twist drill. This reduces the formation of built-up edges and cold welding
on the cutting edges. The taper facilitates retraction when drilling through sheet metal.
