High-Performance Cobalt Drill Bit

This TiAlN-coated cobalt steel drill bit is built for high-speed screw-machine drilling in hard metals. The parabolic flute design improves chip evacuation and coolant flow during deep-hole work. A 135-degree notched point prevents walking and ensures accurate starts in tough alloys.

Who This Suits And Who Should Look Elsewhere

Machinists drilling chilled cast iron, high-speed steel, or stainless steel will benefit from the rigidity and heat resistance. Buyers who need a multi-piece set or bits for soft materials like wood or plastic should choose a different style.

Critical Specification For Fit

The fractional size is 13/32 inch with a matching 13/32 inch shank diameter. Overall length measures 3-5/16 inches and flute length is 1-15/16 inches. Verify these dimensions against your tool holder and hole-depth requirements before purchase.

Questions about this item

How deep can the 13/32 inch drill go before the 1-15/16 flute length limits chip removal?

The flute length of 1-15/16 inches sets the practical depth limit for continuous chip evacuation in deep-hole drilling.

Does the TiAlN coating on the cobalt steel reduce heat buildup when running all day in stainless steel?

The TiAlN finish on the cobalt steel drill improves heat resistance and tool life during sustained high-speed drilling in tough alloys.

What shank size must my drill chuck accept to hold this 13/32 inch bit?

The shank diameter is 13/32 inch, so a chuck that grips at least that size is required.
