Accupro A-6120158R Micro Drill Bit 1.58mm Solid Carbide

Product Description

The ACCUPRO A-6120158R is a solid carbide micro drill bit engineered for precision drilling in small-diameter applications. It measures 1.58 mm (0.0622 inches) in diameter with a 120-degree point angle and a 38 mm overall length. The bright, uncoated carbide construction delivers consistent cutting performance in ferrous and non-ferrous materials where tight tolerances are required. The right-hand spiral flute geometry promotes efficient chip evacuation during the drilling cycle. This bit is part of the Miniature Series and is sold individually, with a minimum order quantity of 10 units.

This micro drill bit is suited for precision machining operations in metalworking, electronics fabrication, tooling, and light manufacturing environments. It is typically used in CNC drilling centers, drill presses, and precision hand-held spindles where controlled feed rates and rigid setups are essential for maintaining hole accuracy at small diameters. The straight-cylindrical shank allows direct chuck mounting in standard collet or Jacobs-style chuck systems.

Key Features

• 1.58 mm (0.0622 inch) cutting diameter for tight-tolerance micro drilling
• 120-degree standard point angle for accurate hole entry and reduced walking
• Solid carbide construction for rigidity and wear resistance in hard materials
• Bright/uncoated finish suitable for a wide range of base materials
• Spiral flute with regular helix for effective chip removal
• Straight-cylindrical shank with 2.00 mm shank diameter for universal chuck compatibility

Compatibility

Designed as an OEM-style miniature drill bit for use in standard collet chucks and drill presses that accept a 2.00 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Ensure the spindle and workpiece are secured before beginning any drilling operation. Use appropriate feed rates and RPM settings for the workpiece material and bit diameter to prevent bit breakage. Inspect the bit for wear or chipping before each use, as solid carbide micro bits are brittle and sensitive to lateral loading.
