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.
