Accupro A-6200120R Micro Drill Bit 1.20mm Solid Carbide

Product Description

The ACCUPRO A-6200120R is a miniature solid carbide micro drill bit designed for precision drilling applications requiring small-diameter, tight-tolerance holes. The cutting diameter measures 1.20 mm (0.0472 inches) with a 140-degree drill point angle suited for flat-entry starts and reduced walking on hard materials. The bit features a bright, uncoated finish and a spiral flute geometry with right-hand cutting direction. Overall length is 50.00 mm with a straight-cylindrical shank diameter of 3.00 mm, making it compatible with standard small-bore collet chucks and drill chucks. Machinists and tooling technicians working in precision manufacturing, PCB fabrication, watchmaking, and similar trades rely on bits in this class for consistent, repeatable results.

This micro drill bit is used in applications that demand small-diameter hole generation in materials such as metals, plastics, and composites. The miniature series designation indicates suitability for CNC machining centers, drill presses, and hand-held precision spindles configured for sub-2 mm tooling. It is well suited for production environments where hole position accuracy and clean entry are critical. The solid carbide construction maintains rigidity at this diameter, reducing deflection during penetration. Sold individually per package with a minimum order quantity of 10 units.

Key Features

• 1.20 mm (0.0472 inch) cutting diameter for precision micro-hole applications
• 140-degree drill point angle reduces walking and improves flat-entry performance
• Solid carbide construction maintains stiffness and wear resistance at miniature diameters
• Bright/uncoated finish compatible with a wide range of workpiece materials
• Spiral flute, right-hand cutting direction for standard CNC and manual spindles
• 3.00 mm straight-cylindrical shank fits common small-bore collet and drill chuck systems

Compatibility

Designed as an OEM-style replacement and standard tooling option for precision spindles and CNC machining setups that accept a 3.00 mm straight-cylindrical shank micro drill bit in the miniature series.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Always power down and lock out the spindle before changing tooling. Carbide bits at this diameter are brittle and susceptible to breakage if subjected to side loading or improper feed rates. Verify collet or chuck runout is within acceptable tolerance before use to avoid premature tool failure.
