Accupro 20413 Solid Carbide Jobber Drill Bit 23/64 Inch

Product Description

The ACCUPRO 20413 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding machining applications. Ground to a 150-degree point angle with a titanium nitride (TiN) coating, this bit delivers extended cutting life and reduced friction compared to uncoated HSS tooling. The 3-flute spiral configuration promotes efficient chip evacuation and improved hole quality. At 4.25 inches overall length with a 2.25-inch flute length, it fits standard jobber-length drill chucks and CNC tool holders. It is sized at 23/64 inch (0.3600 inch decimal) and is intended for use by machinists, toolroom technicians, and industrial maintenance professionals.

This drill bit is suited for ferrous and non-ferrous materials in production and maintenance machining environments. The TiN coating improves wear resistance and is well-suited for drilling steel, aluminum, and similar materials where surface hardness and heat generation are concerns. The right-hand cutting direction and standard point geometry make this a drop-in fit for conventional vertical mills, drill presses, and CNC machining centers using a straight cylindrical shank setup. The ANSI specification designation confirms dimensional compliance with standard jobber-length tolerances.

Key Features

• Solid carbide construction for rigidity and extended tool life over HSS alternatives
• TiN coating reduces friction and improves wear resistance at the cutting edge
• 150-degree point angle for reduced thrust and improved centering on entry
• 3-flute spiral design promotes efficient chip removal and improved surface finish
• Right-hand cut, straight cylindrical shank fits standard drill chucks and collets
• ANSI-compliant jobber-length dimensions ensure compatibility with standard toolholding

Compatibility

Designed as a standard jobber-length drill bit with a straight cylindrical shank, compatible with drill chucks and collet holders sized for 23/64 inch shank tooling on drill presses, vertical mills, and CNC machining centers.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling requirements. Ensure the spindle and chuck are fully de-energized and at rest before installing or removing the bit. Carbide tooling is brittle and should not be subjected to side loads or impact; verify runout and chuck grip before beginning a cut. Follow machine manufacturer guidelines and applicable ANSI safety standards for drill speed and feed selection.
