Accupro A-6120201R Micro Drill Bit 2.01mm Solid Carbide

Product Description

The ACCUPRO A-6120201R is a solid carbide micro drill bit designed for precise small-diameter drilling in tight-tolerance applications. With a 2.01 mm cutting diameter and a 120-degree standard point angle, this bit delivers clean entry and accurate positioning in materials that demand high rigidity and minimal deflection. The bright, uncoated finish suits a wide range of workpiece materials. At 38 mm overall length with a 12 mm flute length and a 3 mm straight-cylindrical shank, this bit is sized for use in CNC machining centers, drill presses, and precision hand-held equipment. Machinists, toolmakers, and precision fabricators are the primary users.

This micro drill bit is suited for small-hole drilling operations in metalworking, electronics manufacturing, medical device fabrication, and precision tooling environments. The miniature series designation indicates it is intended for applications where standard jobber-length bits are too large or too long to maintain positional accuracy. Right-hand spiral flute geometry promotes efficient chip evacuation during through-hole and blind-hole drilling. The straight-cylindrical shank provides consistent seating in standard collets and Jacobs-style chucks without the need for specialized toolholding.

Key Features

• 2.01 mm cutting diameter (0.0791 decimal inch) for tight-tolerance small-hole work
• Solid carbide construction provides rigidity and wear resistance at small diameters
• 120-degree standard point angle for clean entry and reduced thrust force
• Right-hand spiral flute promotes chip clearance during drilling
• Bright, uncoated finish compatible with a broad range of workpiece materials
• 3 mm straight-cylindrical shank fits standard collets and drill chucks

Compatibility

Designed as an OEM-style miniature series solid carbide drill bit suitable for use in CNC machining centers, benchtop drill presses, and precision drilling fixtures that accept a 3 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Ensure the machine spindle and chuck or collet are clean and concentric before seating the shank, as runout at small diameters accelerates breakage. Carbide micro drills are brittle and should not be used in setups with excessive vibration or workpiece movement. Always verify spindle speed and feed rate are appropriate for the diameter and workpiece material before initiating the cut.
