Accupro A-6120064R Micro Drill Bit 0.0252 in Solid Carbide

Product Description

The ACCUPRO A-6120064R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 0.0252 inches in diameter with a 120-degree drill point angle and an overall length of 30.00 mm. The bright, uncoated finish preserves dimensional accuracy and suits a wide range of workpiece materials. The straight-cylindrical shank and spiral flute geometry promote consistent chip evacuation during drilling. This bit is part of the Miniature Series and is installed by machinists, toolroom technicians, and precision fabricators working with CNC drilling equipment or benchtop drill presses.

This micro drill bit fits applications requiring very small-diameter through-holes or pilot holes in metals, plastics, and composites. It is well-suited for PCB fabrication, instrument manufacturing, watch and clock repair, medical device components, and other precision machining environments where hole diameter tolerance is critical. The right-hand cutting direction and regular spiral type are standard for most CNC and manual drilling setups. The 3.30 mm flute length limits engagement depth, making this bit appropriate for shallow-hole applications consistent with its miniature diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• 0.0252-inch diameter with 120-degree point angle for accurate hole entry
• Bright, uncoated finish maintains close dimensional tolerances
• Spiral flute type with 3.30 mm flute length promotes chip clearance
• Straight-cylindrical shank at 1.50 mm diameter fits standard collet chucks
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling option for precision drilling operations requiring a 0.0252-inch diameter solid carbide micro drill bit with a straight-cylindrical shank.

Installation Notes

Micro drill bits of this diameter should be installed and run by experienced machinists familiar with miniature tooling practices. Verify that the spindle and collet are free of runout before securing the shank, as even minor misalignment can cause breakage at this diameter. Use appropriate spindle speeds and feed rates per the workpiece material. Avoid applying side loads or hand pressure during drilling.
