BEYOND HRC65 8D Internal Coolant Solid Carbide Drill (13.0–14.9mm)

BEYOND HRC65 8D Solid Carbide Drills are engineered for deep-hole and high-precision drilling in hard and tough materials. Manufactured from premium fine-grain tungsten carbide and coated with a high-performance nano composite coating, they ensure stable cutting, superior heat resistance, and long service life even under high-speed machining conditions.

Features

• HRC65 ultra-hard carbide substrate – Perfect for hardened steel, die steel, and alloy steel.
• 8D (8×D) long drill design – Enables deep-hole machining with excellent straightness and stability.
• Internal coolant holes – Optimize chip evacuation and cooling during cutting, preventing tool wear.
• High-precision cutting edges – Reduce cutting force and burr formation for smooth hole finishes.
• Advanced TiAlN / Nano coating – Provides oxidation resistance and increases tool life by 2–3 times compared to uncoated tools.

Recommended Materials

Designed for drilling hardened steel (≤65HRC), die steel, cast iron, tool steel, and heat-treated alloy materials.
