Accupro 50451 Carbide Jobber Drill Bit 3/4 in Altin

Product Description

The ACCUPRO 50451 is a solid carbide jobber-length drill bit designed for high-performance drilling in hard and abrasive materials. It measures 3/4 inch (0.7500 inch decimal) in diameter with a 6-inch overall length and a 150-degree drill point angle. The AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in demanding cutting conditions. Three spiral flutes with a regular spiral type provide efficient chip evacuation. This bit is suited for use by machinists, tool-and-die workers, and industrial maintenance technicians working with ferrous and exotic alloy materials.

The ACCUPRO 50451 is intended for use in CNC machining centers, drill presses, and manual mills where a straight-cylindrical shank is compatible with standard collets or drill chucks. The 3-7/8 inch flute length and 5xD flute-to-diameter ratio make it a practical choice for moderate-depth holes in hardened steels, stainless alloys, cast iron, and similar materials. Right-hand cutting direction is standard. This bit does not include coolant-through capability, so external coolant or cutting fluid application is recommended when drilling hard stock.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and extended tool life
• 150-degree drill point angle reduces thrust and improves centering on hard materials
• Three spiral flutes for efficient chip evacuation in deep-hole applications
• Straight-cylindrical shank fits standard collets and drill chucks without adapters
• Right-hand cutting, regular spiral, ANSI specification designation

Compatibility

Designed as a standard jobber-length drill bit with a straight-cylindrical shank conforming to ANSI specifications, compatible with drill chucks and collet systems accepting a 3/4 inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians. Secure the shank fully in the chuck or collet and verify runout before cutting. This bit does not support coolant-through delivery, so apply external cutting fluid or coolant at the cutting zone, especially when drilling ferrous alloys. Follow applicable shop safety standards and machine manufacturer guidelines for RPM and feed rate selection.
