Accupro A-6120264R Micro Drill Bit 2.64mm Solid Carbide

Product Description

The ACCUPRO A-6120264R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It carries a wire gauge size of 37, a decimal inch diameter of 0.1039 inches (2.64 mm), and a 120-degree drill point angle suited for initiating clean, accurate holes in hard or abrasive materials. The bright, uncoated carbide construction provides rigidity and wear resistance without an added coating layer. With an overall length of 38.00 mm and a straight cylindrical shank, this bit is built for use in CNC machining centers, drill presses, and precision hand-held spindles where small-diameter accuracy is critical.

This micro drill bit is appropriate for metalworking, electronics manufacturing, tool and die, and other precision machining trades where small-diameter holes are required in ferrous metals, non-ferrous alloys, and hard plastics. The miniature series designation indicates it is engineered for low-feed, high-speed applications where standard-size bits are too large. It is typically installed and used by machinists, tool and die makers, and precision fabricators working in production or job-shop environments.

Key Features

• Solid carbide construction provides stiffness and wear resistance in hard and abrasive materials
• 120-degree drill point angle supports self-centering and clean hole entry
• Bright, uncoated finish allows direct inspection of tool condition and suits a wide range of materials
• Straight cylindrical shank with 3.00 mm shank diameter fits standard collets and chucks
• Right-hand cutting direction; compatible with standard clockwise spindle rotation
• Spiral flute with regular helix promotes chip evacuation in through-hole and blind-hole drilling

Compatibility

Designed as an OEM-style miniature series replacement drill bit for precision machining applications requiring a 2.64 mm (wire gauge 37) diameter, 3.00 mm straight shank, and 120-degree point geometry in solid carbide.

Installation Notes

Installation and use should be performed by qualified machinists familiar with small-diameter carbide tooling. Power down and lock out the spindle before changing or inspecting bits. Carbide micro drills are brittle and susceptible to breakage from side loading, runout, or improper chuck seating — verify collet or chuck concentricity before use. Follow machine manufacturer feed and speed recommendations for the workpiece material and bit diameter.
