Accupro 10397 Solid Carbide Jobber Drill Bit 19/64 in

Product Description

The ACCUPRO 10397 is a solid carbide jobber-length drill bit designed for precise, high-performance drilling in demanding shop and field applications. Ground to a 150-degree point angle with a standard point type, it delivers clean entry and reduced thrust in hard materials. The bright uncoated finish suits applications where coating adhesion or chemical compatibility is a concern. At 0.2969 inches (19/64 inches) in diameter with an overall length of 3.75 inches, this bit fits standard jobber-length toolholders and drill chucks. It is suited for machinists, tool-and-die workers, and maintenance trades requiring consistent hole geometry in ferrous and non-ferrous materials.

This bit is applied in precision drilling operations on metals, alloys, and engineered materials where carbide hardness and edge retention outperform high-speed steel tooling. The 3-flute geometry with a regular spiral and 1.75-inch flute length improves chip evacuation in through-hole and blind-hole applications. It is a right-hand cutting tool with a straight cylindrical shank, compatible with standard drill chucks and collet holders. Typical users include machinists, tool room technicians, and industrial maintenance professionals working on CNC machines, drill presses, and hand-held power tools where dimensional accuracy is required.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to HSS tooling
• 150-degree point angle reduces thrust and improves centering on entry
• 3-flute spiral design promotes efficient chip evacuation in through-hole and blind-hole drilling
• Bright uncoated finish compatible with a wide range of workpiece materials
• Straight cylindrical shank fits standard drill chucks and collet holders
• Right-hand cutting direction; ANSI specification designation

Compatibility

Designed as an OEM-style replacement and standard tooling option for jobber-length drill bit applications within the 0.2500 to 0.3000 inch decimal inch size range, using standard straight-shank drill chucks and collet systems.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotating cutting tool safety. Ensure the spindle is fully stopped and the machine is locked out before changing bits. Verify chuck or collet runout is within acceptable tolerance before drilling, as excessive runout accelerates carbide edge wear and can cause bit breakage. Solid carbide tooling is brittle and should not be used in applications with significant side load or interrupted cuts without engineering review.
