1/16 Inch Cobalt Drill Bit Set

This set contains twenty jobber length twist drill bits made from M35 cobalt high speed steel with five percent cobalt content. It is designed for machinists and fabricators who need to drill precise holes in hard metals such as stainless steel and cast iron. The bits are manufactured to ANSI B94-11M standards and supplied in a plastic case for organisation.

M35 Cobalt Alloy Capacity and Headroom

The five percent cobalt alloy increases hardness and heat resistance, extending bit life when drilling tough materials. The 135 degree split point improves cutting speed and self-centering while preventing walking on the workpiece. Bits will dull faster if run without coolant or at excessive speeds, and the small diameter offers limited strength for very thick stock.

Straight Shank Fit for Drill Press Use

Each bit features a straight shank compatible with standard three jaw chucks and collets. A drill press is strongly recommended for stability when drilling thick metal to avoid breakage. The plastic case keeps the twenty pieces organised and protects the cutting edges during transport and storage.

Questions about this item

Will the 1/16 inch cobalt bits fit the straight chuck on my older corded drill?

Yes, the straight shank fits any drill chuck that accepts 1/16 inch bits, corded or cordless.

How can I confirm the 135 degree split point is centring correctly on stainless steel?

The bit should start cutting immediately without walking; a clean, round 1/16 inch hole with minimal burr shows it is working.

Does the plastic case hold all 20 pieces and is anything else needed to start drilling cast iron?

The case contains all 20 cobalt bits; you only need a drill, coolant and a stable workpiece or drill press.
