BEYOND HRC65 8D Internal Coolant Solid Carbide Drill (11.0–12.9mm)

BEYOND HRC65 8D Solid Carbide Drills are designed for deep-hole, high-efficiency drilling in hardened and high-strength materials. Made from premium micro-grain tungsten carbide with advanced coating, these drills deliver exceptional wear resistance, heat stability, and long service life.

Features

• High hardness up to HRC65 – Ideal for hardened steel, die steel, and alloy steel.
• 8D deep-hole design (8×D length-to-diameter ratio) – Ensures stable and accurate drilling in deep cavities.
• Internal coolant holes – Improve chip evacuation and cooling during high-speed machining.
• Optimized cutting edge geometry – Reduces cutting force and prevents edge chipping.
• TiAlN / Nano coating – Provides superior oxidation resistance and longer tool life.

Recommended Materials

Suitable for machining hardened steel (≤65HRC), die steel, cast iron, alloy steel, and stainless steel.
