Accupro A-6100076R Micro Drill Bit 0.0299 in Solid Carbide

Product Description

The ACCUPRO A-6100076R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. At 0.0299 inches in diameter with a 120-degree drill point angle, this bit is built for miniature-series work where accuracy and tool integrity are critical. The bright/uncoated solid carbide construction provides excellent hardness and wear resistance without added coating thickness, making it well-suited for applications where dimensional precision at the cutting edge matters. The straight-cylindrical shank and right-hand cutting direction make it compatible with standard drill chucks and CNC tool holders. It weighs 0.25 pounds and has an overall length of 30.00 mm.

This micro drill bit is used in precision machining environments including tool and die work, electronics manufacturing, medical device fabrication, and other applications requiring sub-1mm bore diameters. The miniature series designation indicates suitability for controlled, low-feed-rate drilling in materials where surface finish and hole accuracy are priorities. Machinists and CNC operators working with small-format workpieces will find the 6.30 mm flute length and 1.50 mm shank diameter appropriate for shallow to moderate-depth micro holes.

Key Features

• 0.0299 inch (sub-1 mm) diameter for precision micro drilling
• Solid carbide construction for hardness and dimensional stability
• 120-degree drill point angle suits a wide range of base materials
• Bright/uncoated finish preserves edge sharpness and cutting-edge tolerance
• Right-hand spiral flute with straight-cylindrical shank for standard chuck compatibility
• Miniature series with 30.00 mm overall length and 6.30 mm flute length

Compatibility

Designed as an OEM-style miniature drill bit for use in CNC machining centers, drill presses, and precision hand-held drilling equipment that accept a 1.50 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or CNC technicians familiar with micro tooling. Ensure the spindle and chuck are clean and properly seated before securing the shank to avoid runout. At this diameter, feed rate and spindle speed must be carefully controlled to prevent bit breakage. Always power down and de-energize the machine before changing tooling.
