20-Piece Cobalt Drill Bit Set

This 20-piece set supplies 3/32 inch cobalt drill bits made from M35 high-speed steel with 5% cobalt content. The bits target users who drill hardened metal, stainless steel, cast iron, plastic, PVC board and wood. A plastic storage case keeps the pieces organised.

Upgrade From Standard HSS Bits

The M35 cobalt alloy is harder than conventional high-speed steel, so it resists wear when cutting tough alloys that dull ordinary bits quickly. The jump is worth it when you regularly drill stainless steel or hardened steel and need longer edge life between sharpenings.

Straightforward Jobber-Length Install

The 135-degree split point centres itself on hard surfaces and reduces walking, so the bit starts where you place it without a centre punch. The main risk is snapping the small 3/32 inch diameter if you apply excessive side load or run the drill at too high a speed without lubrication.

Questions about this item

What size plastic case holds the 20 cobalt bits?

The set ships in a plastic storage case sized for 20 pieces of 3/32" diameter bits.

How do I start a hole without the bit walking on hardened steel?

Use the 135° split-point tip; press firmly at low speed to engage the self-centering geometry before increasing RPM.

When should I replace a bit from this M35 set?

Replace when the cutting edges show visible rounding or when drilling force increases noticeably on stainless steel or cast iron.
