Accupro 63310338 Carbide Jobber Drill Bit 5/8 Inch

Product Description

The ACCUPRO 63310338 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and trade applications. It measures 5/8 inch (0.6250 inch decimal) in diameter with a 5-inch overall length and a 2.75-inch flute length. The bit features a 140-degree notched point for accurate starting and reduced thrust, a web-thinned parallel web for improved chip evacuation, and an AlTiN (Aluminum Titanium Nitride) coating that extends tool life in abrasive and high-heat cutting conditions. The straight-cylindrical shank seats securely in standard drill chucks without modification.

This bit is suited for machining operations that require tight tolerances and consistent hole quality in ferrous metals, stainless steel, cast iron, and hard alloys. The regular spiral flute geometry with a 4xD flute-to-diameter ratio handles a maximum drilling depth of 2.5 inches per pass. It is intended for use in CNC machining centers, drill presses, and handheld power tools where a solid carbide substrate and AlTiN coating provide a significant performance advantage over high-speed steel alternatives. Right-hand cut geometry is standard for conventional clockwise-rotation spindles.

Key Features

• Solid carbide construction for rigidity and long tool life in hard materials
• AlTiN coating provides heat and wear resistance in abrasive cutting environments
• 140-degree notched point reduces walking and improves hole entry accuracy
• Web-thinned parallel web lowers cutting forces and improves chip flow
• Straight-cylindrical 5/8-inch shank fits standard drill chucks and collets
• Right-hand cut, regular spiral flute for conventional spindle operation

Compatibility

Designed as an OEM-style replacement or direct-fit solid carbide jobber drill bit for applications requiring a 5/8-inch diameter, straight-cylindrical shank bit in CNC or manual drilling equipment.

Installation Notes

Install in a compatible drill chuck or collet sized for a 5/8-inch straight shank and torque to the tool holder manufacturer's specification. Ensure spindle speed and feed rate are set per the material being drilled — solid carbide bits require appropriate RPM and coolant or air-blast management to prevent thermal shock. Do not use this bit in hammer-drill mode. Inspect the cutting edges and coating before each use; chipped carbide should not be run.
