Accupro A-6200060R Micro Drill Bit 0.0236 in Solid Carbide

Product Description

The ACCUPRO A-6200060R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Measuring 0.0236 inches in diameter with a 140-degree drill point angle, this bit delivers clean, accurate entry in hard and abrasive materials where standard high-speed steel tooling falls short. The bright, uncoated finish is well suited for applications where coating buildup or heat transfer is a concern. With an overall length of 50.00 mm and a straight-cylindrical shank measuring 3.00 mm in diameter, it mounts reliably in standard precision chucks. Machinists, tool and die technicians, and CNC operators working on micro-scale components use this bit in high-precision production and prototype work.

This bit is part of the Miniature Series and is intended for micro drilling operations in materials such as hardened steel, stainless, composites, and other demanding substrates. It is commonly used in CNC machining centers, drill presses, and precision hand-held setups where hole diameter accuracy and edge integrity are critical. The right-hand cutting direction is standard for conventional spindle rotation. Applications include electronics component manufacturing, medical device fabrication, and precision instrument production where sub-millimeter hole geometry is required.

Key Features

• 0.0236 inch drill diameter for micro-scale precision hole making
• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree drill point angle reduces thrust force and improves centering
• Spiral flute with 4.50 mm flute length promotes chip evacuation in shallow holes
• Bright, uncoated finish suitable for dry cutting and coolant-free operations
• Straight-cylindrical shank at 3.00 mm diameter for secure chuck retention

Compatibility

Designed as a standard straight-shank micro drill bit compatible with precision chucks and collet systems accepting a 3.00 mm shank diameter.

Installation Notes

This bit is installed and operated by machinists and CNC technicians using precision drill chucks or collet holders matched to the 3.00 mm shank diameter. Secure the shank fully in the chuck before operation and verify runout with a dial indicator when tolerances are critical. Due to the small diameter, feed rates and spindle speeds must be set conservatively to prevent breakage; consult published carbide tooling feeds-and-speeds references for the specific workpiece material. Coolant through is not available on this bit, so ensure adequate chip clearance during use.
