Accupro A-6120180R Micro Drill Bit 1.80mm Solid Carbide

Product Description

The ACCUPRO A-6120180R is a solid carbide micro drill bit designed for precision drilling in tight tolerances and small-diameter applications. With a 1.80 mm (0.0709 inch) cutting diameter and a 120-degree drill point angle, this bit delivers clean, accurate entry points in hard and abrasive materials where high-speed steel tooling falls short. The bright/uncoated solid carbide construction offers rigidity and wear resistance without the added coating layer, keeping tolerances predictable. An overall length of 38.00 mm and a 2.00 mm straight-cylindrical shank make it compatible with standard collet chucks and micro drill holders. Machinists and toolroom technicians use this bit for precision CNC work, PCB drilling, and instrument manufacturing.

This miniature series drill bit is suited for small-part machining operations in precision manufacturing environments, including aerospace component work, electronics fabrication, and medical device production. The right-hand cutting direction and spiral flute geometry support standard spindle rotation and efficient chip evacuation in shallow-to-moderate depth holes. The 8.40 mm flute length provides adequate chip relief for the bit diameter class. It is sold individually with a minimum order quantity of 10 units, making it appropriate for shop stock replenishment and toolcrib applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 1.80 mm cutting diameter with 120-degree standard point angle for precise entry
• Bright/uncoated finish maintains close dimensional tolerances without coating buildup
• Straight-cylindrical 2.00 mm shank fits standard collet chucks and micro holders
• Spiral regular flute type with right-hand cutting direction for standard CNC spindles
• 38.00 mm overall length suited to miniature series drill chuck clearance requirements

Compatibility

Designed as an OEM-style replacement and standard-stock micro drill bit for precision machining applications requiring a 2.00 mm straight-cylindrical shank and 1.80 mm cutting diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully in a collet chuck or micro drill holder and verify runout before starting the spindle. Power down and lock out the machine before changing tooling. Do not exceed the recommended depth-to-diameter ratio for the material being drilled, as micro carbide bits are brittle and susceptible to breakage under side load or chatter.
