Quarter-Inch Carbide Bit For Abrasive Materials

This quarter-inch solid carbide drill bit handles abrasive workpieces where dimensional accuracy must be held. The uncoated bright finish suits high-temperature drilling in cast iron, non-ferrous alloys, high-silicon aluminum, copper, plastics, bronze, hard rubber and plexiglass. It is built for operators who need consistent hole quality in tough, abrasive stock.

Round Shank And Flute Geometry Deliver Rigid

The 2-inch flute length and 3-1/4-inch overall length give a compact, stiff cutting zone that resists deflection in hard materials. A plain round shank fits standard drill chucks and collets without special adapters. Solid carbide construction maintains sharpness far longer than high-speed steel when cutting abrasive or high-silicon content metals.

Uncoated Carbide Requires Coolant Management

Bright finish means no coating to mask wear, so the operator must monitor edge condition and apply appropriate coolant or air blast. The bit is not suited for general-purpose steel, stainless steel or soft, gummy materials that load the flutes. Buyers needing coated tool life, through-coolant capability or a shank flats for CNC holders should select a different drill.

Questions about this item

Will the uncoated solid carbide tip need resharpening or replacement after drilling abrasive materials like cast iron?

The solid carbide construction maintains accuracy in abrasive materials, but the uncoated finish will eventually wear and require resharpening or replacement depending on usage intensity.

What stops me drilling deeper than the 2" flute length in one pass?

The 2" flute length limits chip clearance in a single plunge; deeper holes need peck drilling or a longer bit to avoid clogging.

Does the bright uncoated carbide run hotter than coated bits during all-day high-temperature drilling?

Uncoated carbide generates more friction heat in sustained high-temperature drilling, so coolant or reduced feed rates help manage temperature.
