Accupro A-6120242R Micro Drill Bit 2.42 Mm Solid Carbide

Product Description

The ACCUPRO A-6120242R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It features a 2.42 mm cutting diameter, a 120-degree point angle, and a right-hand spiral flute configuration. The bright, uncoated finish preserves dimensional accuracy and suits applications where coating buildup is a concern. With an overall length of 38 mm and a 3.00 mm straight-cylindrical shank, this bit is sized for use in CNC machining centers, drill presses, and precision hand tools. Machinists and tooling technicians working on small-diameter hole work rely on this series for consistent performance in hard and abrasive materials.

This micro drill bit is suited for small-diameter precision hole drilling in metalworking, electronics fabrication, and light manufacturing environments. Its miniature series classification makes it appropriate for applications requiring tight positional accuracy and controlled chip evacuation. The 12 mm flute length supports effective chip removal in shallow to moderate-depth holes. It is typically used in production machining and prototype shops where hole diameters under 3 mm are common and repeatability is critical.

Key Features

• 2.42 mm cutting diameter (0.0953 inch decimal equivalent) for precision micro-hole work
• Solid carbide construction for rigidity and wear resistance in hard materials
• 120-degree standard point angle for accurate entry and reduced walking
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Bright/uncoated finish — no coating thickness variation affecting hole size
• Straight-cylindrical 3.00 mm shank for compatibility with standard collets and chucks

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers, drill presses, and precision drilling fixtures that accept a 3.00 mm straight-cylindrical shank micro drill bit.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with small-diameter tooling protocols. Ensure the machine spindle and collet or chuck are clean and properly torqued before seating the shank. Micro-diameter carbide tooling is brittle — avoid side-loading, interrupted cuts without proper feeds and speeds, or dropping the bit on hard surfaces. Always follow the machine tool manufacturer guidelines for spindle speed and feed rate when working with carbide micro drills.
