HRC65 Super Hard Drill Bits(Solid)

HRC65 Super Hard Solid Drill (Solid Type)

High-Performance Solid Carbide Drill for Hardened Steel Applications

Engineered for precision drilling in hardened steels up to HRC65, this solid carbide drill is ideal for high-speed, high-efficiency machining of materials such as tool steel, mold steel, and alloy steel. Featuring a 140° point angle, it offers exceptional positioning accuracy, reduced cutting resistance, and reliable performance under dry or MQL conditions. Available in 3×D and 5×D length-to-diameter ratios to accommodate standard and deep-hole drilling.

Built for Hardened Materials (HRC46–68)
Manufactured using ultra-fine grain carbide substrate for maximum wear resistance and fracture toughness, enabling consistent performance on heat-treated, high-strength steels under heavy-load conditions.

140° Point Geometry for Superior Accuracy
Optimized point angle design minimizes tool deflection and walking, ensuring precise hole location and improved surface finish. Ideal for automated CNC operations demanding tight tolerance control.

Available in 3×D and 5×D Depths
Choose from multiple flute lengths to handle both standard-depth and deep-hole drilling tasks—perfect for mold cavities, structural parts, and other complex applications.

Solid Structure – No Internal Coolant Required
Designed for machines without internal coolant delivery. Performs reliably in dry machining or MQL environments, offering a cost-effective solution without compromising tool life or hole quality.

5-Axis CNC Precision Ground
Manufactured using advanced 5-axis CNC grinding to ensure consistent tool geometry, sharp cutting edges, and excellent concentricity—crucial for repeatability in high-volume production.
