Accupro A-6200175R Micro Drill Bit 1.75 Mm Solid Carbide

Product Description

The ACCUPRO A-6200175R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance and small-diameter applications. It measures 1.75 mm (0.0689 inches) in diameter with a 140-degree drill point angle and an overall length of 50.00 mm. The bright/uncoated finish is well-suited for use in materials where coating transfer or contamination must be avoided. With a 3.00 mm straight-cylindrical shank and a 12.50 mm spiral flute length, this bit delivers accurate chip evacuation in miniature drilling operations. Machinists, toolroom technicians, and precision fabricators are the typical end users.

This micro drill bit belongs to the Miniature Series and is built for applications requiring very small hole diameters — such as PCB fabrication, instrument components, medical device manufacturing, and precision metalwork. The right-hand cutting direction and standard point type make it compatible with conventional CNC machining centers, drill presses, and precision hand tools equipped for small-shank tooling. It is sold individually, with a minimum order quantity of 10 units, making it appropriate for shop-level stock replenishment.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter drilling
• 1.75 mm (0.0689 inch) drill diameter with a 140-degree point angle for clean entry
• 12.50 mm spiral flute length promotes efficient chip evacuation
• 3.00 mm straight-cylindrical shank for broad collet and chuck compatibility
• Bright/uncoated finish eliminates coating variables in sensitive applications
• Right-hand cutting direction, standard point type, regular spiral for predictable performance

Compatibility

Designed as an OEM-style replacement or stock drill bit for miniature series micro drilling applications in CNC machining centers and precision drill presses accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Ensure the spindle and collet are fully de-energized and brought to a complete stop before changing tooling. Carbide is brittle — avoid side-loading or flexing during setup. Confirm collet or chuck bore matches the 3.00 mm shank diameter before securing the bit.
