Accupro A-6120270R Micro Drill Bit Size 36 Solid Carbide

Product Description

The ACCUPRO A-6120270R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. It carries a wire gauge size of 36, equivalent to 2.70 mm (0.1063 inches) in diameter. The 120-degree standard point angle promotes accurate entry and reduces walking on hard or dense materials. With a bright, uncoated finish and a right-hand spiral flute, this bit is suited for machinists, tool-and-die technicians, and precision fabricators who need reliable performance at tight tolerances in miniature-series drilling operations.

This drill bit is used in precision machining environments where small-hole drilling is required in metals, plastics, or composites. The straight-cylindrical shank accommodates standard drill chucks and collet holders commonly found on CNC machining centers, drill presses, and manual mills. The miniature series designation makes it a practical choice for printed circuit board work, instrument manufacturing, mold making, and other applications demanding tight dimensional control. It is sold individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction provides hardness and wear resistance for extended tool life in demanding materials
• 120-degree standard point angle for accurate hole entry and reduced bit drift
• Bright, uncoated finish suitable for use in a wide range of base materials without coating compatibility concerns
• Right-hand cut with regular spiral flute for efficient chip evacuation in through and blind holes
• Straight-cylindrical shank fits standard collets and drill chucks without adapters
• Miniature series dimensions with a 38 mm overall length and 14 mm flute length for compact tooling setups

Compatibility

Designed as an OEM-style miniature drill bit for use in standard straight-shank drill chucks and collet systems that accept a 3.00 mm shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool technicians familiar with rotating cutting tools. Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable tolerance for the application. Do not exceed the recommended spindle speed for the workpiece material and bit diameter. Inspect the cutting edges for wear or chipping before each use, as micro-diameter carbide tooling is brittle and susceptible to breakage under side loading or improper feed rates.
