Precision Cobalt Set

The Sabre Tools CO116 provides five identical 1/16 inch cobalt drill bits built from M35 alloy for professional metalwork. Split-point tips prevent walking and accelerate penetration in hard materials. This set targets machinists and maintenance crews who repeatedly drill the same small diameter in tough alloys.

Upgrade From Standard HSS

The M35 cobalt construction replaces general-purpose high-speed steel bits when heat and abrasion wear out cutting edges too quickly. Cobalt retains hardness at higher temperatures, so the step up pays off in stainless steel, cast iron and titanium alloy where standard bits dull fast. Buyers who only drill soft steel or wood will not see the benefit.

Five-Piece Redundancy

Five bits of the same size give enough spares for a full production run or a multi-day job without re-sharpening. The 1/16 inch diameter handles pilot holes and fine clearance work in metal, hard plastics and wood. It runs out when the application demands larger diameters, deeper reach or a broader assortment of sizes in one package.

Questions about this item

What size drill chuck is needed for the 1/16 inch shank on these CO116 bits?

The 1/16 inch shank fits any standard drill chuck that accepts 1/16 inch or smaller bits, including common 3/8 inch and 1/2 inch keyless or keyed chucks.

How do I start a hole with the split-point tip without the bit walking on stainless steel?

Apply firm, steady pressure at low speed; the split-point tip on the M35 cobalt bits self-centres so you do not need a centre punch — just let the tip bite before increasing RPM.

When should I replace a bit from this 5-piece set?

Replace a bit when the cutting edges no longer produce clean chips in steel or cast iron, or when the split-point tip shows visible rounding after repeated resharpening.
