Accupro A-6100145R Micro Drill Bit 1.45 Mm Solid Carbide

Product Description

The ACCUPRO A-6100145R is a miniature solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a 1.45 mm (0.0571 inch) cutting diameter and a 120-degree point angle, this bit delivers clean, accurate entry in hard and abrasive materials where standard high-speed steel tooling falls short. The bright, uncoated finish suits a wide range of materials without altering dimensional tolerances. At 30 mm overall length with an 11.20 mm flute length, the compact geometry is built for controlled chip evacuation in shallow-to-moderate depth holes. Machinists and toolroom technicians working with precision components rely on solid carbide construction for rigidity and wear resistance at small diameters.

This bit is suited for use in CNC machining centers, drill presses, and precision benchtop machines where micro-diameter work is required. Typical applications include circuit board drilling, watch and instrument components, medical device parts, mold work, and other miniature fabrication tasks. The right-hand spiral flute promotes consistent chip removal during the cut. The straight-cylindrical shank at 1.50 mm diameter fits standard collet chucks used in high-speed spindles common to precision machining setups.

Key Features

• 1.45 mm cutting diameter with 0.0571 inch decimal equivalent for precise tool selection
• Solid carbide construction for rigidity and extended tool life in hard materials
• 120-degree standard point angle for accurate self-centering on entry
• Bright, uncoated finish compatible with a broad range of workpiece materials
• Right-hand spiral flute promotes effective chip evacuation
• 1.50 mm straight-cylindrical shank fits standard collet systems

Compatibility

Designed as an OEM-style miniature drill bit for use in standard collet chucks and toolholders accepting a 1.50 mm straight-cylindrical shank, typical of CNC machining centers and precision drilling equipment.

Installation Notes

Installation of micro drill bits should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet to prevent runout, which is especially critical at sub-2 mm diameters. Use appropriate spindle speeds and feed rates for the workpiece material and bit diameter; exceeding recommended parameters at this diameter will result in rapid tool failure.
