Accupro A-6120217R Micro Drill Bit 2.17mm Solid Carbide

Product Description

The ACCUPRO A-6120217R is a solid carbide micro drill bit designed for precision drilling in tight tolerances and small-diameter applications. It measures 2.17 mm (0.0854 inches) in diameter with a 120-degree drill point angle and an overall length of 38 mm. The bright/uncoated finish is suited for use in materials where coating buildup or contamination must be avoided. This bit belongs to the Miniature Series and is intended for machinists, tool and die technicians, and precision fabricators who require consistent, repeatable performance at small diameters.

This micro drill bit is used in precision machining environments such as mold making, electronics manufacturing, medical device fabrication, and small-component production. The straight-cylindrical shank fits standard collet and chuck systems. With a 12 mm flute length and right-hand cutting direction, it is suited for CNC machining centers, drill presses, and manual milling setups where small-hole accuracy is critical.

Key Features

• 2.17 mm (0.0854 inches) drill diameter for micro and miniature hole applications
• Solid carbide construction provides rigidity and wear resistance at small diameters
• 120-degree point angle suitable for standard drilling operations
• Bright/uncoated finish — no coating interference in sensitive material applications
• Straight-cylindrical shank with 3 mm shank diameter for broad collet compatibility
• Regular spiral flute with right-hand cutting direction for conventional chip evacuation

Compatibility

Designed as an OEM-style replacement or stock tooling for precision drilling setups requiring a 3 mm straight-cylindrical shank and 2.17 mm cutting diameter in Miniature Series applications.

Installation Notes

Installation should be performed by a qualified machinist familiar with micro tooling handling. Secure the shank fully in a properly sized collet or drill chuck before operation, and verify runout is within acceptable limits before engaging the workpiece. At micro diameters, excessive feed rates or lateral loading can cause bit deflection or breakage — always follow the tooling manufacturer's recommended speeds and feeds for the workpiece material. Power down and lock out all equipment before changing or inspecting tooling.
