Large Steel Drill Bits Reduced Shank or ‘Blacksmith’ Bits

Ruko’s German large steel drill bits are commonly known as ‘Blacksmith’ bits.

These large steel drill bits should be used at much slower speeds than smaller bits. If using on metals always use a cutting paste or spray to provide cooling and lubrication to the bit.

For use on processed iron, steel, aluminium, plastic, wood, copper, and other metal materials.

Using high-quality, high-speed steel, hardened through special treatment.
