Accupro A-6120211R Micro Drill Bit 2.11mm Solid Carbide

Product Description

The ACCUPRO A-6120211R is a solid carbide micro drill bit engineered for precision drilling in small-diameter applications. It measures 2.11 mm (0.0831 inches) in diameter with a 120-degree drill point angle, an overall length of 38.00 mm, and a 3.00 mm straight cylindrical shank. The bright, uncoated finish makes it well suited for materials where coating adhesion or chip evacuation properties are not the primary concern. The spiral flute geometry promotes consistent chip removal, while the standard point type delivers accurate entry. This bit is part of the Miniature Series and is sold individually, with a minimum order quantity of 10 units.

This micro drill bit is designed for use in tight-tolerance, small-part drilling environments such as electronics assembly, instrument manufacturing, mold and die work, and precision machining operations. Its 12.00 mm flute length and right-hand cutting direction suit CNC machining centers, drill presses, and hand-held precision spindles where controlled feed rates and high RPM are common. Machinists, toolroom technicians, and production operators working with close-tolerance bores will find this bit appropriate for materials including plastics, non-ferrous metals, and softer steels.

Key Features

• 2.11 mm (0.0831 inch) drill diameter for micro and miniature bore applications
• Solid carbide construction provides rigidity and wear resistance in small-diameter drilling
• 120-degree point angle for controlled entry on a wide range of materials
• 12.00 mm spiral flute length supports efficient chip evacuation in shallow-to-moderate depth holes
• 3.00 mm straight cylindrical shank compatible with standard precision collets and chucks
• Bright, uncoated finish with no coolant-through feature — suited for low-to-moderate heat applications

Compatibility

Designed as an OEM-style replacement and standard tooling option for precision machining setups requiring a 2.11 mm micro drill bit with a 3.00 mm straight shank and 38.00 mm overall length in the Miniature Series configuration.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with small-diameter cutting tools. Secure the shank fully in a precision collet or drill chuck before operation, and verify runout is within acceptable tolerances before engaging the workpiece. Always set spindle speed and feed rate appropriate for the workpiece material and drill diameter — micro carbide tools are brittle and susceptible to breakage under side load or excessive feed pressure. Do not use damaged or chipped bits.
