Accupro A-6120226R Micro Drill Bit Wire 43 Solid Carbide

Product Description

The ACCUPRO A-6120226R is a solid carbide micro drill bit designed for precision drilling in tight tolerances and small-diameter applications. This wire gauge size 43 bit measures 0.0890 inches (2.26 mm) in diameter with an overall length of 38 mm. The 120-degree point angle and spiral flute geometry promote clean chip evacuation and accurate hole entry. Solid carbide construction delivers the rigidity and wear resistance needed for consistent performance in hard or abrasive materials. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern.

This miniature drill bit is suited for precision machining operations in metalworking, electronics manufacturing, and tooling applications where small-diameter holes are required. The straight-cylindrical shank with a 3.00 mm shank diameter seats securely in standard collet chucks and drill chucks designed for miniature tooling. The 12.00 mm flute length provides adequate chip clearance for shallow-to-moderate depth holes in ferrous and non-ferrous metals as well as plastics. Right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• Wire gauge size 43 diameter: 0.0890 inches (2.26 mm) for precision small-hole work
• Solid carbide construction for rigidity and extended tool life in hard materials
• 120-degree point angle for accurate entry and reduced walking on flat surfaces
• Spiral flute with regular spiral type for efficient chip evacuation
• Bright uncoated finish compatible with a wide range of workpiece materials
• Straight-cylindrical 3.00 mm shank fits standard miniature collet and drill chuck systems

Compatibility

Designed for use in CNC machining centers, drill presses, and precision hand-held drilling equipment fitted with collet or drill chucks that accept a 3.00 mm straight-cylindrical shank in the miniature tooling series.

Installation Notes

Micro drill bits should be installed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet or chuck to prevent runout, which can cause premature breakage at this diameter. Use appropriate spindle speeds and feed rates for the workpiece material — excessive feed pressure is the leading cause of breakage in micro-diameter carbide drills.
