Accupro A-6100065R Micro Drill Bit 0.0256 in Solid Carbide

Product Description

The ACCUPRO A-6100065R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Built from solid carbide with a bright uncoated finish, it delivers consistent performance in hard and abrasive materials where high-speed steel would deflect or wear prematurely. The bit features a 120-degree drill point angle, a standard point type, and a right-hand cutting direction. At 0.0256 inches in diameter with a 30.00 mm overall length and a 5.00 mm flute length, this miniature-series bit is suited for fine work requiring accurate hole placement and minimal runout. A straight-cylindrical shank at 1.50 mm diameter provides secure seating in compatible chucks and collets.

This micro drill bit is used in precision machining, electronics manufacturing, printed circuit board fabrication, instrument manufacturing, and other applications that require very small diameter holes. It is well-suited for CNC machining centers, benchtop drill presses, and hand-piece spindles equipped with collet systems capable of holding a 1.50 mm straight shank. The miniature series designation indicates suitability for small-scale, high-precision work where standard-sized drill bits are too large for the application.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 0.0256 inch diameter with 120-degree point angle for accurate hole entry
• Bright uncoated finish suitable for a wide range of materials without coating interference
• Regular spiral flute type promotes chip evacuation in miniature drilling operations
• Straight-cylindrical shank at 1.50 mm for secure collet or chuck retention
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed for use in CNC machining centers, drill presses, and precision spindles equipped with collet systems or chucks accepting a 1.50 mm straight-cylindrical shank. Verify spindle runout and chuck concentricity before use, as excess runout at this diameter will cause premature breakage.

Installation Notes

Micro drill bits at this diameter are fragile and must be installed by a qualified machinist or tool operator familiar with miniature tooling. Ensure the machine spindle is fully powered down and locked before changing tooling. Use a precision collet sized for a 1.50 mm shank to minimize runout. Do not apply side loads or use excessive feed rates, as solid carbide at this diameter is brittle and will snap under lateral stress.
