Accupro A-6200110R Micro Drill Bit 1.1 Mm Solid Carbide

Product Description

The ACCUPRO A-6200110R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 1.1 mm in diameter (0.0433 inches) with a 50 mm overall length and an 8 mm flute length. The 140-degree point angle promotes accurate entry and reduces walking on hard or smooth surfaces. The bright, uncoated finish maintains close dimensional tolerances and suits a wide range of base materials. Right-hand spiral flutes evacuate chips efficiently during the drilling cycle. This bit belongs to the Miniature series and is built for machinists, tool-and-die makers, and precision fabricators who require consistent performance at small diameters.

The A-6200110R is suited for precision drilling operations in metalworking, electronics fabrication, medical device manufacturing, and other applications where small-diameter holes and tight tolerances are critical. The straight-cylindrical shank with a 3 mm diameter seats securely in standard collets and chucks. This bit is appropriate for use in CNC machining centers, drill presses, and high-speed hand tools configured for miniature tooling. It is sold individually with a minimum order quantity of 10 units.

Key Features

• 1.1 mm diameter with 0.0433-inch decimal equivalent for precise hole sizing
• Solid carbide construction provides hardness and wear resistance for demanding materials
• 140-degree point angle reduces drill walk and improves entry accuracy
• Bright/uncoated finish maintains tight dimensional tolerances
• Right-hand spiral flute promotes efficient chip evacuation
• 3 mm straight-cylindrical shank fits standard miniature collets and chucks

Compatibility

Designed as a miniature-series replacement or stock drill bit compatible with standard collet systems and chucks accepting a 3 mm straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with high-speed cutting operations. Ensure the spindle and workpiece are secured before engaging the drill. Use appropriate RPM settings for the material and bit diameter to avoid bit fracture, which is a common risk at sub-2 mm diameters. Do not apply excessive feed pressure; carbide micro bits are brittle and will snap under lateral load or sudden feed increases.
