Accupro A-6120294R Micro Drill Bit 2.94 Mm Solid Carbide

Product Description

The ACCUPRO A-6120294R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. With a 2.94 mm (0.1157 inch) drill diameter and a 120-degree point angle, this bit delivers accurate entry and consistent hole geometry in hard materials. The straight-cylindrical shank measures 3.00 mm in diameter, and the overall length is 38.00 mm with a 14.00 mm flute length. The bright, uncoated finish keeps the cutting edge geometry clean and is well suited for materials where coating buildup or heat transfer would affect accuracy. Machinists and toolroom technicians working with CNC machining centers, drill presses, or precision manual equipment will find this bit compatible with their standard collet and chuck setups.

This micro drill bit fits residential and commercial shop environments where small-diameter, tight-tolerance hole making is required. Typical applications include precision metalworking, light alloy drilling, PCB prototype work, and instrument component fabrication. The miniature series designation means this bit is built for jobs where standard jobber-length drills are too large or too long for the required feature depth. The right-hand cutting direction is standard for conventional CNC and manual spindle rotation.

Key Features

• 2.94 mm (0.1157 inch) drill diameter for precision micro-hole applications
• 120-degree point angle suits a broad range of metallic and non-metallic materials
• Solid carbide construction provides rigidity and wear resistance in hard or abrasive materials
• Bright uncoated finish maintains dimensional accuracy without coating buildup
• 3.00 mm straight-cylindrical shank fits standard collets and chucks
• Spiral flute with regular spiral type for consistent chip evacuation in short-depth holes

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and manual machines equipped with collets or drill chucks accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

Installation of micro drill bits should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and locked out before inserting or removing the bit from the collet or chuck. Confirm runout with a dial indicator before production use, as even minor misalignment at this diameter will accelerate tool wear or cause breakage. Follow machine manufacturer feed and speed guidelines for carbide tooling at this diameter range.
