Accupro A-6120288R Micro Drill Bit 2.88mm Solid Carbide

Product Description

The ACCUPRO A-6120288R is a solid carbide micro drill bit designed for precision small-diameter drilling applications. With a cutting diameter of 2.88 mm (0.1134 inches) and a 120-degree drill point angle, this bit is engineered for accurate hole placement and clean entry in tight-tolerance work. The bright/uncoated finish suits a wide range of base materials where coating is not required or preferred. At 38.00 mm overall length with a 14.00 mm flute length, the compact geometry keeps deflection low in micro-drilling operations. This bit is typically installed by machinists, toolroom technicians, and precision fabricators working with CNC or benchtop drill press setups.

This micro drill bit fits applications in light machining, electronics fabrication, instrument manufacturing, and precision prototype work where small-diameter holes are required. The straight cylindrical shank with a 3.00 mm diameter seats securely in standard collets and chucks. The right-hand cutting direction and regular spiral flute design provide reliable chip evacuation in through-hole and blind-hole operations across metals, composites, and plastics commonly encountered in precision shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in micro-diameter drilling
• 2.88 mm (0.1134 inches) cutting diameter for tight-tolerance hole sizing
• 120-degree standard drill point angle for accurate positioning and reduced thrust
• 14.00 mm spiral flute length supports effective chip clearance in shallow and moderate-depth holes
• 3.00 mm straight cylindrical shank for secure seating in standard collets and chucks
• Bright/uncoated finish — no coating interference for applications requiring bare carbide contact

Compatibility

Designed as an OEM-style replacement or production tooling option for precision drilling setups requiring a 2.88 mm solid carbide micro drill bit with a 3.00 mm straight shank in the Miniature series.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or toolroom personnel familiar with micro-diameter cutting tools. Power down and lock out all spindle drives before changing tooling. Seat the shank fully and evenly in the collet or chuck to the manufacturer-specified grip depth to prevent runout and bit breakage. Micro drill bits are brittle at small diameters — do not apply side load or use in hand-held drilling operations.
