Accupro A-6120093R Micro Drill Bit 0.0366 in Solid Carbide

Product Description

The ACCUPRO A-6120093R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. Built to a 0.0366-inch diameter with a 120-degree drill point angle, this bit delivers clean, accurate entry in hard and abrasive materials where standard high-speed steel bits fall short. The bright, uncoated finish keeps tolerances consistent right out of the package. With an overall length of 30.00 mm and a spiral flute design, this bit is suited for machinists, toolmakers, and production shops that require repeatable performance at micro diameters.

This bit is intended for use in precision drilling operations where small hole diameters and tight positional accuracy are required. Typical applications include PCB drilling, watch and instrument components, medical device manufacturing, and fine metalworking. The straight cylindrical shank at 1.50 mm diameter is compatible with standard collet and chuck systems used on CNC machining centers, drill presses, and precision hand-held spindles. The right-hand cutting direction suits conventional right-hand spindle rotation setups.

Key Features

• 0.0366-inch drill diameter for micro and miniature bore applications
• Solid carbide construction provides hardness and wear resistance in abrasive materials
• 120-degree point angle suits a wide range of materials and reduces walking on entry
• Spiral flute geometry with regular spiral promotes chip evacuation in short-hole drilling
• Bright, uncoated finish maintains dimensional consistency without coating buildup
• Straight cylindrical shank fits standard collets and chucks without modification

Compatibility

Designed as an OEM-style miniature drill bit for use in precision spindles and collet systems accepting a 1.50 mm straight cylindrical shank.

Installation Notes

Installation and use of this micro drill bit should be performed by qualified machinists or tooling technicians familiar with small-diameter drilling. Secure the shank fully and concentrically in the collet or chuck to minimize runout, which is critical at micro diameters. Use appropriate cutting speeds and feed rates for solid carbide tooling in the workpiece material; excessive feed pressure is the primary cause of breakage in micro drill bits. Do not use this bit for hand drilling without a precision guiding fixture.
