Accupro A-6100122R Micro Drill Bit 1.22 Mm Solid Carbide

Product Description

The ACCUPRO A-6100122R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. Ground to a 1.22 mm (0.0480 inch) diameter with a 120-degree point angle, this bit delivers clean entry and accurate hole placement in tight-tolerance work. The straight-cylindrical shank measures 1.50 mm in diameter, and the overall length is 30 mm with a 10 mm flute length. Solid carbide construction provides the rigidity and wear resistance needed for consistent performance in hard or abrasive materials. The bright, uncoated finish suits applications where coating buildup or contamination is a concern.

This micro drill bit is used in precision machining, electronics manufacturing, printed circuit board fabrication, instrument work, and other applications requiring small-diameter, high-accuracy holes. The spiral flute with regular helix promotes chip evacuation in short, controlled cuts. It is suited for use in CNC machining centers, drill presses, and precision hand-held or bench-top spindles where runout is well controlled. Machinists, tool-and-die makers, and electronics fabricators working with metals, plastics, and composites are the primary users of this series.

Key Features

• 1.22 mm (0.0480 inch) drill diameter for precision micro-hole applications
• Solid carbide construction for rigidity and extended tool life in hard materials
• 120-degree standard point angle for accurate hole entry
• Spiral flute with regular helix for efficient chip evacuation
• Straight-cylindrical shank at 1.50 mm diameter for secure chuck grip
• Bright, uncoated finish — no coating interference in sensitive applications

Compatibility

Designed for use in precision spindles, CNC machining centers, and bench-top drill presses that accept a 1.50 mm straight-cylindrical shank. Part of the ACCUPRO Miniature series for small-diameter drilling operations.

Installation Notes

Micro drill bits at this diameter are fragile and require a well-trued, low-runout chuck or collet to prevent breakage. Ensure the spindle and workpiece are rigidly fixtured before drilling. Feed rates and spindle speeds should be appropriate for the workpiece material and bit diameter — consult published cutting data for solid carbide micro drills. Do not use excessive downward force; allow the bit geometry to do the cutting work.
