Accupro 10345 Solid Carbide Jobber Drill Bit 3 Mm

Product Description

The ACCUPRO 10345 is a solid carbide jobber-length drill bit designed for precision drilling in hard and abrasive materials. Built from solid carbide with a bright uncoated finish, this bit delivers consistent performance in applications where high rigidity and heat resistance are critical. It features a 150-degree standard point angle, a three-flute regular spiral configuration, and a straight cylindrical shank. The overall length is 2.28 inches with a flute length of 0.79 inches. The 3-flute design improves chip evacuation and reduces cycle times in production drilling environments. Machinists, toolroom technicians, and CNC operators typically work with this bit.

This drill bit is suited for use in machining centers, CNC mills, and drill presses where tight-tolerance hole-making is required. The 3 mm diameter and 5xD flute-to-diameter ratio make it appropriate for drilling in stainless steel, hardened steel, cast iron, and other difficult-to-machine materials. Its solid carbide construction and standard point geometry support both through-hole and blind-hole applications in production and job-shop settings. Right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 150-degree standard point angle reduces thrust and improves centering
• Three-flute spiral design promotes efficient chip removal
• Bright uncoated finish suitable for use with cutting fluids or dry
• Straight cylindrical shank for compatibility with standard drill chucks and collets
• Right-hand cutting direction for use with conventional spindle rotation

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard drill chucks and collets accepting a 3 mm straight cylindrical shank across CNC machining centers, knee mills, and bench drill presses.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Ensure the spindle is fully stopped and the machine is powered down before loading or changing the bit. Carbide tooling is brittle and should not be subjected to side loads or improper seating in the chuck or collet. Verify spindle runout is within acceptable limits before use to prevent premature chipping or breakage.
