Accupro A-6120235R Micro Drill Bit 2.35 Mm Solid Carbide

Product Description

The ACCUPRO A-6120235R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. The bit measures 2.35 mm (0.0925 inches) in diameter with a 120-degree drill point angle and a 38.00 mm overall length. The straight-cylindrical shank diameter is 3.00 mm, and the spiral flute length is 12.00 mm. The bright/uncoated finish preserves dimensional accuracy and makes tool wear easier to monitor. This bit is part of the Miniature Series and is used by machinists and precision fabricators working in metal, composites, and other materials that demand fine-hole accuracy.

The A-6120235R suits CNC machining centers, drill presses, and precision hand-held equipment where small-diameter hole generation is required. Its right-hand cutting direction and regular spiral flute geometry are standard for through-hole and blind-hole drilling in small-part manufacturing, electronics enclosures, medical device components, and similar close-tolerance work. The miniature form factor makes it appropriate for applications where standard-sized drill bits cannot access the required feature geometry.

Key Features

• Solid carbide construction delivers hardness and wear resistance for small-diameter precision work
• 120-degree drill point angle reduces thrust force and suits a wide range of material types
• Bright/uncoated finish allows direct inspection of tool wear progression
• Straight-cylindrical shank (3.00 mm) provides secure chuck engagement in standard collets and keyless chucks
• Regular spiral flute type promotes efficient chip evacuation in short-flute micro drilling
• Standard point type ensures compatibility with conventional drill press and CNC spindle setups

Compatibility

Designed as an OEM-style miniature series replacement or stock drill bit for use in standard 3.00 mm straight-cylindrical collets and chucks on CNC machining centers, drill presses, and compatible precision drilling equipment.

Installation Notes

Micro drill bits should be installed by a qualified machinist or tooling technician familiar with small-diameter tooling practices. Secure the straight shank fully into the collet or chuck before operation to prevent runout and premature breakage. Always verify spindle speed and feed rate are appropriate for the material and diameter before initiating a cut. Micro carbide tooling is brittle — avoid side loading, interrupted cuts, or excessive hand pressure.
