Accupro A-6120130R Micro Drill Bit 1.3mm Solid Carbide

Product Description

The ACCUPRO A-6120130R is a solid carbide micro drill bit engineered for precision drilling in tight-tolerance applications. Measuring 1.3 mm (0.0512 inches) in diameter with a 120-degree point angle, this bit delivers clean entry and accurate hole positioning in hard and abrasive materials. The spiral flute geometry promotes efficient chip evacuation, reducing heat buildup and extending tool life. At 30 mm overall length with a 6.7 mm flute length and a 1.5 mm straight-cylindrical shank, this miniature-series bit is built for controlled, low-vibration drilling in precision machining environments. It ships uncoated with a bright finish, weighing 0.25 pounds per unit.

This micro drill bit is suited for precision drilling operations in metalworking, electronics manufacturing, mold and die work, and other applications requiring tight dimensional tolerances at small diameters. The right-hand cut and regular spiral configuration make it compatible with standard CNC machining centers, drill presses, and precision hand-held spindles operating at appropriate high-speed feeds and speeds for carbide tooling. It is intended for use by machinists, toolmakers, and precision manufacturing professionals working with small-diameter holes in hard substrates.

Key Features

• 1.3 mm (0.0512 inches) drill diameter for micro-precision hole making
• 120-degree point angle for accurate self-centering on entry
• Solid carbide construction for rigidity and wear resistance in hard materials
• Spiral flute design promotes chip evacuation and reduces heat buildup
• Straight-cylindrical shank at 1.5 mm diameter for secure chuck retention
• Bright/uncoated finish compatible with a wide range of cutting fluids and materials

Compatibility

Designed as a miniature-series solid carbide drill bit for use in standard precision spindles, CNC machining centers, and drill presses equipped with collets or chucks accepting a 1.5 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with micro-diameter carbide tooling. Ensure the spindle and collet or chuck are clean and properly seated before securing the shank to prevent runout. Carbide tooling is brittle and susceptible to breakage under lateral load — avoid side pressure and use appropriate feed rates for the material being drilled. Always verify spindle speed and feed rate are appropriate for 1.3 mm carbide tooling before beginning a cut.
