Accupro A-6120074R Micro Drill Bit Size 69 Solid Carbide

Product Description

The ACCUPRO A-6120074R is a size 69 wire gauge micro drill bit designed for precision drilling in tight-tolerance applications. Built from solid carbide, it delivers the rigidity and wear resistance required when working with hard or abrasive materials at small diameters. The 120-degree point angle provides a standard tip geometry suited to general-purpose micro drilling. At 0.0291 inches in diameter, this bit operates in the miniature drill series and is suited for machinists, tool-and-die professionals, and electronics fabricators who require consistent, repeatable hole quality at very small scales.

This micro drill bit is intended for use in CNC machining centers, drill presses, and precision hand-held drill fixtures where small-diameter, high-accuracy holes are required. Common applications include PCB drilling, instrument component manufacturing, mold work, and fine metalworking. The straight-cylindrical shank at 1.50 mm diameter seats reliably in standard collets and chucks designed for miniature tooling. The bright, uncoated finish makes it easy to inspect for wear. Right-hand spiral flute geometry promotes chip evacuation during through-hole and blind-hole operations.

Key Features

• Size 69 wire gauge diameter — 0.0291 inches — for precision micro drilling
• Solid carbide construction for rigidity and extended tool life in hard materials
• 120-degree standard point angle for general-purpose entry geometry
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank at 1.50 mm for secure collet or chuck retention
• Bright uncoated finish allows easy visual wear inspection

Compatibility

Designed for use in CNC machining centers, precision drill presses, and collet-based fixtures accepting a 1.50 mm straight-cylindrical shank. Suitable for drilling ferrous and non-ferrous metals, plastics, and composites in miniature series tooling setups.

Installation Notes

Installation and use of micro drill bits should be performed by qualified machinists or tool operators familiar with small-diameter carbide tooling. Secure the shank fully in a collet or chuck rated for the 1.50 mm diameter before operation. Carbide tooling is brittle — avoid lateral loading, side pressure, or impacts that can cause chipping or breakage. Machine speeds and feeds should be set per the workpiece material specifications for the drill diameter; consult tooling reference data before use.
