Accupro A-6120098R Micro Drill Bit 0.98 Mm Solid Carbide

Product Description

The ACCUPRO A-6120098R is a solid carbide micro drill bit engineered for precision drilling in small-diameter applications. Built from solid carbide throughout, this bit delivers the rigidity and wear resistance needed when drilling hard or abrasive materials at tight tolerances. The 120-degree point angle provides a standard, versatile cutting geometry suited to a wide range of workpiece materials. With a 0.98 mm diameter (0.0386 inches) and a 30 mm overall length, this miniature-series bit is sized for fine detail work in machining, electronics, and precision fabrication environments. A bright, uncoated finish maintains dimensional accuracy at the cutting edge.

This micro drill bit is designed for use in CNC machining centers, drill presses, and precision hand-held or benchtop drilling equipment capable of holding a 1.50 mm straight-cylindrical shank. It is well-suited for applications in electronics manufacturing, instrument production, watchmaking, medical device fabrication, and any precision metalworking or composite drilling operation where small hole diameters and accurate positioning are required. The miniature series designation makes it appropriate for production environments running small-feature components at controlled feed and speed parameters.

Key Features

• Solid carbide construction for superior hardness and extended tool life in abrasive materials
• 0.98 mm drill diameter with 0.0386-inch decimal equivalent for precise hole sizing
• 120-degree standard point angle for versatile entry geometry across common workpiece materials
• Spiral flute with regular helix promotes chip evacuation in blind and through-hole drilling
• 1.50 mm straight-cylindrical shank for compatibility with standard micro chuck systems
• Bright, uncoated finish preserves close dimensional tolerances without coating buildup
• 4.80 mm flute length suited to shallow micro-hole depths typical in miniature-series applications

Compatibility

Designed as a miniature-series solid carbide micro drill bit compatible with precision drilling equipment accepting a 1.50 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by machinists or tooling technicians familiar with micro-diameter tooling. Ensure the spindle and chuck are clean and true before seating the shank, as runout at this diameter range will rapidly degrade hole quality and tool life. Use manufacturer-recommended speeds and feeds for solid carbide micro bits in the specific workpiece material. Coolant-through is not supported on this bit, so air blast or flood coolant directed at the cutting zone is recommended for chip clearing during deep drilling.
