Accupro A-6120038R Micro Drill Bit 0.0150 in Solid Carbide

Product Description

The ACCUPRO A-6120038R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Built to the Miniature Series specification, this bit measures 0.0150 inches in diameter with a 120-degree drill point angle and a standard point type. The overall length is 25.00 mm, and the straight-cylindrical shank diameter is 1.00 mm. The bright/uncoated finish maintains dimensional accuracy straight from the factory. Right-hand cutting direction and a regular spiral flute configuration support clean chip evacuation in small-bore drilling operations. This bit is suited for machinists, toolmakers, and precision fabricators working in metals, composites, or plastics at micro scales.

The A-6120038R is used in precision machining environments where extremely small hole diameters are required. Typical applications include printed circuit board drilling, instrument manufacturing, mold and die work, and aerospace component fabrication. The spiral flute type and 1.60 mm flute length are optimized for shallow, controlled cuts in materials where bit deflection and breakage are primary concerns. Coolant-through capability is not included, so flood or mist cooling methods applied externally are standard practice for this style of bit.

Key Features

• 0.0150 inch diameter for micro-precision hole drilling
• Solid carbide construction for rigidity and wear resistance at small diameters
• 120-degree drill point angle with standard point type for accurate entry
• Bright/uncoated finish preserves tight dimensional tolerances
• Regular spiral flute with 1.60 mm flute length for controlled chip removal
• Straight-cylindrical shank at 1.00 mm diameter for standard collet compatibility

Compatibility

Designed as a miniature-series replacement or production drill bit for use in standard precision collet chucks and micro drill presses accepting a 1.00 mm straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or toolroom technicians using a collet or micro chuck rated for 1.00 mm shank diameter. Ensure the spindle is fully stopped and de-energized before inserting or removing the bit. At this diameter, feed rate and spindle speed must be carefully controlled to avoid bit fracture; consult published carbide micro-drill speed and feed charts for the specific workpiece material. No coolant-through path is present, so external cooling should be applied as needed per shop practice.
