Accupro A-6200190R Micro Drill Bit 1.9mm Solid Carbide

Product Description

The ACCUPRO A-6200190R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a 1.9 mm (0.0748 inch) diameter and a 140-degree standard point angle, this bit delivers clean entry geometry and accurate hole placement. The spiral flute design promotes efficient chip evacuation, reducing heat buildup and extending tool life. The straight-cylindrical shank measures 3.0 mm in diameter, providing solid seating in compatible chucks and collet holders. At 50.0 mm overall length with a 13.5 mm flute length, this is a compact tool built for controlled, repeatable micro-drilling work. Installation is performed by machinists and tooling technicians working in precision fabrication environments.

This drill bit is suited for small-diameter hole drilling in metals, plastics, and composite materials where tight tolerances and clean hole finish are required. The bright uncoated finish makes it appropriate for general-purpose micro-drilling where coating compatibility with specific materials is a concern. Right-hand cut geometry is standard for conventional drill press and CNC spindle operation. This bit belongs to the Miniature series and is packaged individually, with a minimum order quantity of 10 units.

Key Features

• 1.9 mm (0.0748 inch) drill diameter for precise micro-hole applications
• 140-degree standard point angle for accurate starting and clean entry
• Solid carbide construction for rigidity and wear resistance in hard materials
• Spiral flute with right-hand cut for efficient chip removal
• Straight-cylindrical 3.0 mm shank for broad chuck and collet compatibility
• Bright uncoated finish suitable for general-purpose micro-drilling

Compatibility

Designed as an OEM-style replacement or direct tooling selection for precision drilling setups requiring a 3.0 mm straight-cylindrical shank micro drill bit in the Miniature series.

Installation Notes

Installation should be performed by qualified machinists or tooling technicians following standard tool-change procedures. Secure the shank fully in the collet or chuck before operation and verify runout before drilling. Power down the spindle completely before changing tooling. Do not use this bit beyond its rated diameter or force it into materials without appropriate feed and speed settings for carbide micro tooling.
