21/64" Hybrid Split Drill Bit – 4.6" Length, 3‑flat Shank

Presenting Diablo 21/64" Hybrid Split Drill Bit, a precision‑engineered cutting tool designed for demanding metalworking tasks. This 4.6‑inch overall length bit features a robust 3‑flat shank for secure chuck engagement, while the 130° hybrid split point delivers fast starts and reduced walking on hardened and stainless steel surfaces.

Why choose this drill bit? Its metal‑based cutting edge maintains sharpness longer, allowing you to bore clean holes in tough alloys without frequent replacements. The 3‑inch flute length provides ample chip evacuation, ensuring smoother operation and lower heat buildup during high‑speed drilling.

• Hybrid Split Point (130°): Combines the aggressiveness of split point geometry with a robust tip for superior hole accuracy in hardened steel.
• 3‑Flat Shank Design: Guarantees a tight grip in standard chucks, minimizing slippage and enhancing torque transfer.
• 21/64" Diameter, 4.6" OAL: Ideal for medium‑size holes in a wide range of metal applications, from automotive to fabricating.
• Metal Cutting Edge Material: Engineered for durability, it resists wear when drilling mild steel, stainless steel, and other alloyed metals.
• 3‑Inch Flute Length: Optimized chip removal reduces clogging, extending bit life and improving surface finish.

Experience unmatched performance: Whether you’re tackling hardened steel fasteners or precision stainless steel components, this Diablo drill bit delivers consistent results. Its rugged construction and advanced point geometry translate into faster drilling cycles, lower tool wear, and cleaner holes. Upgrade your toolbox with a bit that stands up to the toughest metalworking challenges and keeps your projects on schedule.
