Accupro A-6100193R Micro Drill Bit Size 48 Solid Carbide

Product Description

The ACCUPRO A-6100193R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It carries a wire gauge size of 48, equivalent to 1.93 mm or 0.0760 inches in decimal inch. The 120-degree point angle provides a standard cutting geometry suited to a wide range of materials. At 38 mm overall length with a 12 mm flute length, this bit is built for miniature-series drilling work where control and accuracy are critical. The bright, uncoated finish keeps the carbide surface exposed for direct material contact. Right-hand cutting direction and a regular spiral flute type are standard on this bit.

This micro drill bit is used in precision machining environments including CNC drilling operations, toolroom work, and production runs requiring small-diameter holes. The straight-cylindrical shank with a 2 mm shank diameter seats securely in standard collets and chucks. It is suited for machinists, toolmakers, and production operators working with printed circuit boards, watch components, medical device parts, aerospace assemblies, and other fine-tolerance workpieces where a wire-gauge drill size is specified.

Key Features

• Solid carbide construction for rigidity and wear resistance in micro drilling
• Wire gauge size 48 — 1.93 mm / 0.0760 inches decimal equivalent
• 120-degree standard point angle for consistent entry geometry
• Bright, uncoated finish — no coating thickness to account for in tight-tolerance bores
• Regular spiral flute with right-hand cut for positive chip evacuation
• Straight-cylindrical 2 mm shank fits standard collets and keyless chucks

Compatibility

Designed as an OEM-style miniature-series micro drill bit for use in standard collet chucks and drill chucks accepting a 2 mm straight-cylindrical shank diameter.

Installation Notes

Micro drill bits of this size are installed and operated by machinists using CNC machining centers, drill presses, or precision hand pieces equipped with appropriate collets. Ensure the spindle and workpiece are secured before operation, and confirm collet runout is within tolerance to avoid bit deflection or breakage at this diameter. Carbide bits are brittle — avoid side loads and do not use them for hand-held freehand drilling. Follow facility safety protocols and applicable OSHA machine guarding requirements when operating rotating tooling.
