Accupro 20377 Solid Carbide Jobber Drill Bit 15/64 in

Product Description

The ACCUPRO 20377 is a solid carbide jobber-length drill bit with a titanium nitride (TiN) coating, designed for precision drilling in metal, composite, and hard-material applications. The bit measures 15/64 inches (0.2344 inches) in diameter with an overall length of 3.25 inches. It features a 3-flute spiral design with a 150-degree drill point angle, which reduces thrust and improves chip evacuation compared to standard 2-flute geometry. The straight cylindrical shank ensures compatibility with standard drill chucks and collet holders. This bit is sold individually and is suited for production and maintenance trades requiring consistent hole quality.

This jobber-length drill bit is intended for use in CNC machining centers, drill presses, and handheld power tools where a solid carbide cutting tool is required. The 5xD flute-to-diameter ratio and regular spiral type make it appropriate for general-purpose drilling in ferrous and non-ferrous metals, plastics, and fiber-reinforced composites. Machinists, tool-and-die technicians, and maintenance professionals in manufacturing and fabrication environments are the primary installers and users of this bit.

Key Features

• Solid carbide construction provides hardness and wear resistance for extended tool life in demanding materials
• TiN coating reduces friction and increases surface hardness at the cutting edge
• 150-degree drill point angle lowers entry thrust and improves positioning accuracy
• 3-flute spiral geometry enhances chip removal and improves hole finish
• Straight cylindrical shank fits standard drill chucks and collet systems
• Right-hand cutting direction; ANSI specification designation

Compatibility

Designed as an OEM-style jobber-length drill bit suitable for standard drill chucks and collet holders accepting a straight cylindrical shank in the 0.2000 to 0.2500 inch diameter range.

Installation Notes

This bit should be installed by machinists or qualified trade professionals familiar with rotary cutting tool procedures. Ensure the spindle or drill is fully powered down and secured before changing bits. Verify chuck or collet grip is secure and concentric to prevent runout that can damage carbide tooling. Carbide bits are brittle compared to high-speed steel — avoid lateral loading or impact that could cause chipping or fracture.
