Accupro A-6120247R Micro Drill Bit 2.47 Mm Solid Carbide

Product Description

The ACCUPRO A-6120247R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. It measures 2.47 mm (0.0972 inches) in diameter with an overall length of 38 mm and a flute length of 12 mm. The 120-degree standard point angle provides clean entry geometry suited to tight-tolerance work. Bright/uncoated finish keeps the surface true to the carbide substrate, making it a practical choice when coating buildup would affect hole size accuracy. This bit is used by machinists, toolmakers, and precision fabricators working in materials where a miniature-series drill is required.

This bit is suited for small-hole drilling operations in metalworking, electronics manufacturing, mold and die work, and other precision machining environments. The right-hand spiral flute design evacuates chips efficiently during through-hole and blind-hole drilling. The straight-cylindrical shank at 3.00 mm diameter seats in standard collets and drill chucks without special adapters, making it compatible with CNC machining centers, drill presses, and precision hand tools configured for miniature tooling.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter drilling
• 2.47 mm (0.0972 inches) drill diameter with 120-degree standard point angle
• Bright/uncoated finish preserves tight dimensional tolerances at the cutting edge
• Right-hand cut with regular spiral flute for consistent chip evacuation
• Straight-cylindrical 3.00 mm shank fits standard collets and drill chucks
• Miniature series at 38 mm overall length for use in confined setups

Compatibility

Designed for use in miniature-series tooling setups requiring a 3.00 mm straight-cylindrical shank; fits standard collets and drill chucks compatible with that shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Secure the shank fully in the collet or chuck before operation and verify runout before drilling. Carbide is brittle — avoid lateral loading or flex during use, as this can cause tip breakage. Follow machine manufacturer guidelines for spindle speed and feed rate when working with miniature carbide drills.
