Accupro A-6100149R Micro Drill Bit 1.49 Mm Solid Carbide

Product Description

The ACCUPRO A-6100149R is a solid carbide micro drill bit designed for precision drilling in miniature applications. Built from solid carbide, it delivers the rigidity and wear resistance required when working with tight tolerances at small diameters. The 1.49 mm (0.0587 inches) cutting diameter and 120-degree drill point angle are suited for controlled entry and clean hole formation in hard or abrasive materials. With an overall length of 30.00 mm and a straight-cylindrical shank, this bit fits standard collet systems used in CNC machining centers, drill presses, and precision hand-held spindles. It is installed and used by machinists, toolmakers, and precision fabricators.

This micro drill bit is intended for miniature drilling operations where small hole diameters and accurate positioning are critical. Typical applications include PCB drilling, instrument components, watch and medical device parts, and precision tooling work. The bright uncoated finish and spiral flute geometry allow effective chip evacuation in shallow-to-moderate depth holes. No coolant-through capability is required for most standard dry or externally lubricated setups where this bit class is used.

Key Features

• 1.49 mm (0.0587 inches) cutting diameter for miniature precision drilling
• Solid carbide construction provides rigidity and wear resistance
• 120-degree drill point angle for controlled entry
• Bright uncoated finish suits a wide range of base materials
• Spiral flute with straight-cylindrical shank fits standard collet systems
• 11.20 mm flute length supports effective chip clearance in standard-depth holes

Compatibility

Designed as an OEM-style replacement and standard fit for precision drilling applications using straight-cylindrical shank collets accepting a 1.50 mm shank diameter.

Installation Notes

This bit should be installed by a qualified machinist or tooling technician. Always power down and lock out the spindle before changing tooling. Use a precision collet matched to the 1.50 mm straight-cylindrical shank to ensure runout is minimized. Avoid side-loading or prying with micro-diameter carbide bits, as solid carbide is brittle and will fracture under lateral stress.
