Product Description

Product Details of Solid Carbide drill bit 

Premium TiCN Black Coating (Extreme Wear Resistance): Our advanced TiCN (Titanium Carbonitride) coating provides a unique combination of high surface hardness and an ultra-low friction coefficient. This effectively prevents material adhesion and heat buildup, significantly extending tool life in carbon and alloy steels.

140° Self-Centering Point Geometry: Specifically engineered for maximum stability. The 140-degree split point ensures instant centering, eliminating the need for pilot holes. It reduces axial force and provides a stable, clean entry into high-strength alloys and cast iron.

High-Density HRC 50 Carbide Substrate: Crafted from an ultra-fine micrograin substrate with a hardness of HRC 50. This ensures the structural integrity needed to withstand high-torque drilling while maintaining a sharp, precise cutting edge across large production batches.

Comprehensive Diameter Range (D0.5-D20): From precision micro-drilling to heavy-duty industrial applications, SITELUN provides a complete size range with h6 precision straight shanks, ensuring minimum runout and maximum clamping stability in all CNC machine tools.
