Accupro A-6200250R Micro Drill Bit 2.50 Mm Solid Carbide

Product Description

The ACCUPRO A-6200250R is a solid carbide micro drill bit engineered for precision drilling in tight-tolerance applications. Measuring 2.50 mm (0.0984 inches) in diameter with an overall length of 50.00 mm, this bit features a 140-degree drill point angle suited for harder materials and flat-bottomed entry requirements. The straight-cylindrical shank diameter is 3.00 mm, and the spiral flute length runs 18.00 mm. The bright/uncoated finish leaves the carbide substrate exposed for direct heat dissipation. Machinists, toolroom technicians, and precision fabricators install this bit in CNC machining centers, drill presses, and hand-held precision drilling fixtures.

This bit is part of the ACCUPRO Miniature Series, targeting applications that demand small-diameter, high-accuracy hole generation. Typical use cases include PCB drilling, instrument component fabrication, medical device machining, and aerospace detail work where hole diameter tolerance and positional accuracy are critical. The right-hand cutting direction is standard for conventional drill press and CNC spindle rotation. No coolant-through capability means this bit relies on flood or mist coolant applied externally, or dry cutting at appropriate feed and speed parameters.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 2.50 mm (0.0984 inches) drill diameter with 3.00 mm straight-cylindrical shank for secure chuck retention
• 140-degree point angle for reduced thrust force and improved centering on entry
• 18.00 mm spiral flute length with regular spiral for efficient chip evacuation
• Bright/uncoated finish — no coating to chip or peel in micro-diameter applications
• Right-hand cutting, standard point type, compatible with conventional spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use micro drill bit for CNC machining centers and drill presses accepting a 3.00 mm straight-cylindrical shank. Part of the ACCUPRO Miniature Series.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank fully in the collet or drill chuck before operation, and verify runout with a dial indicator when tolerance is critical. Power down and lock out the spindle before changing bits. Do not exceed manufacturer-recommended feed and speed parameters for the work material, as micro-diameter carbide bits are brittle and susceptible to breakage under side load or excessive feed force.
