Accupro A-6120045R Micro Drill Bit 0.45 Mm Solid Carbide

Product Description

The ACCUPRO A-6120045R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. It measures 0.45 mm (0.0177 inches) in diameter with a 25 mm overall length and a 1.00 mm straight-cylindrical shank. The 120-degree point angle and spiral flute geometry promote accurate entry and efficient chip evacuation in tight tolerances. The bright, uncoated finish is suited for non-abrasive materials where a coating is not required. This bit is part of the Miniature series and is intended for use by machinists, toolmakers, and precision fabricators working in industries where small-bore accuracy is critical.

This micro drill bit is used in precision machining environments such as electronics manufacturing, medical device fabrication, instrument production, and fine metalwork. The right-hand cutting direction and regular spiral flute make it compatible with standard CNC machining centers, micro drill presses, and manual precision fixtures. It is appropriate for drilling into metals and similar materials where dimensional accuracy at sub-millimeter diameters is required. This item is sold individually with a minimum order quantity of 10 units.

Key Features

• 0.45 mm diameter (0.0177 inches) for sub-millimeter precision drilling
• Solid carbide construction for rigidity and wear resistance in tight tolerances
• 120-degree standard point angle for accurate positioning and clean entry
• Spiral flute with right-hand cut for efficient chip removal
• Straight-cylindrical shank at 1.00 mm diameter for secure chuck retention
• Bright, uncoated finish - no coating interference in sensitive applications

Compatibility

Designed as an OEM-style replacement or standard tooling option for micro drilling applications requiring a 1.00 mm straight shank and 0.45 mm cutting diameter in CNC or manual precision drilling setups.

Installation Notes

Installation of micro drill bits should be performed by a qualified machinist or toolroom technician. Ensure the spindle and chuck are clean and free of debris before seating the shank to prevent runout. Always confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter before operation. Handle carbide tooling with care to avoid chipping the cutting edge during loading and unloading.
