Drill Bit Set for Hard Metals

This Olympia Tools set contains 10 cobalt drill bits with a 135 degree tip made from M35 high-speed steel. The jobber length twist design suits hard metal, stainless steel, cast iron, wood and plastic. A sturdy plastic case provides storage and carrying convenience.

Suits Repetitive Drilling Tasks

The uniform hardness allows repeated sharpening without damaging the cutting edge, ideal for workshops needing long-lasting bits. Builders requiring a wider range of diameters or larger set counts such as 13, 15, 21, 29 or 115 pieces should look at other options.

Simple Chuck Installation

The straight shank fits standard drill chucks and prevents walking for precise positioning. Users must ensure the chuck is tightened securely to avoid slippage during high-torque applications on tough alloys.

Questions about this item

What chuck size do I need for the 1/8 inch shank on these M35 cobalt bits?

A standard three-jaw chuck that opens to at least 1/8 inch will hold the straight shank securely.

Will the 135 degree tip cut cleanly in the cast iron and stainless steel I already drill with high-speed steel bits?

The M35 alloy with 5 percent cobalt resists heat better than standard HSS, so it stays sharp longer in hard metals.

How can I confirm the bits are performing as intended after the first few holes?

Look for quick penetration with light pressure, minimal walking at the start, and chips clearing cleanly from the flutes.
