View Product Description

Precision Carbide Drill for Aluminum Uncoated 135° Point Angle 1mm-20mm

Introduction:

Our uncoated tungsten carbide drill bit is specifically engineered for high-speed, precision drilling in aluminum and non-ferrous metals. Featuring a 135° point angle and ultra-sharp cutting edges, this drill delivers clean, burr-free holes with exceptional chip evacuation—perfect for CNC machining, aerospace components, and high-volume production.

The absence of coating ensures optimal cutting performance in sticky aluminum alloys, while the micro-grain carbide construction provides 3X longer life than standard HSS drills.
