Accupro 63309868 Carbide Jobber Drill Bit 19/64 in

Product Description

The ACCUPRO 63309868 is a solid carbide jobber-length drill bit designed for high-performance metal drilling applications. It features an AlTiN (aluminum titanium nitride) coating that extends tool life by reducing heat buildup and friction at the cutting edge. The 140-degree notched point promotes fast penetration and accurate hole entry without the need for a center punch on most materials. At 3 inches overall length with a 1.484-inch flute length, this bit is sized for general-purpose jobber work across a range of workpiece thicknesses. It is suited for machinists, tool-and-die technicians, and metalworking professionals running production or maintenance drilling operations.

This drill bit is intended for use in CNC machining centers, knee mills, drill presses, and compatible handheld power tools where a straight-cylindrical shank is accepted. The 5/16-inch shank diameter fits standard drill chucks in that size range. The regular spiral flute geometry and web-thinned, parallel-web construction support efficient chip evacuation in steels, stainless alloys, cast iron, and similar materials. It is a high-performance grade tool suited for shops requiring consistent hole quality and extended run times between tool changes.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating reduces thermal load and extends cutting edge life
• 140-degree notched point for fast, accurate hole entry and reduced thrust force
• Web-thinned parallel web supports chip clearance and reduces walking at entry
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a high-performance replacement or addition for jobber-length drill bit applications requiring a 19/64-inch (0.2969 inch) diameter hole in metalworking environments where solid carbide tooling is specified.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the chuck is properly tightened to the rated shank diameter before operation. Verify spindle speed and feed rate are set to values appropriate for the workpiece material and bit diameter per standard machining reference charts. Do not use coolant-through settings, as this bit does not support internal coolant delivery.
