Solid Carbide Drill Bit 1/8

This solid carbide drill bit from Drill America is built for precise drilling in abrasive and high-temperature applications. The uncoated bright finish and 118 degree point geometry suit materials such as cast iron, non-ferrous alloys, high-silicon aluminum, copper, plastics, bronze, hard rubber and plexiglass. It is intended for users who need dimensional accuracy and tool life in demanding production or maintenance tasks.

Best for abrasive and high-heat materials

Machinists and fabricators working with cast iron, composites or hardened plastics will benefit from the carbide construction and rigid round shank. The bit is not suited for general-purpose wood or soft-steel drilling where a high-speed steel twist drill would be more economical and less brittle. Buyers needing coated tools for extended wear in ferrous metals should consider alternative styles.

Straightforward round-shank mounting

The plain round shank fits standard drill chucks and collets without adapters, so installation is a simple clamp-and-run step. The main risk is carbide brittleness: excessive feed rates, misalignment or sudden impact can fracture the cutting edges. Proper workholding, consistent coolant flow and conservative speeds reduce the chance of breakage.

Questions about this item

What chuck size do I need for the 1/8" round shank on this drill bit?

A standard drill chuck that accepts a 1/8" round shank is required; the bit has a 1/8" diameter shank and 2-1/4" overall length.

Will the 118° point angle work effectively in my older drill press when cutting cast iron?

Yes, the 118° point is suited for general-purpose drilling in cast iron and similar abrasive materials on conventional equipment.

How can I confirm the bit is performing correctly after I start drilling?

Expect clean, accurate holes without wandering; the solid carbide construction maintains precision in high-temperature or abrasive applications.
