Accupro 63309884 Carbide Jobber Drill Bit 2mm Altin

Product Description

The ACCUPRO 63309884 is a solid carbide jobber-length drill bit designed for precision drilling in hard and abrasive materials. Measuring 2 mm in diameter with an overall length of 38 mm and a flute length of 13.5 mm, this bit features a 140-degree notched point for accurate self-centering entry and reduced thrust. The AlTiN (aluminum titanium nitride) coating increases surface hardness and heat resistance, extending tool life in high-speed applications. The web-thinned, parallel web construction reduces cutting resistance. Right-hand spiral flutes efficiently evacuate chips during through and blind-hole drilling operations. Machinists and toolroom technicians working with hardened steels, stainless, cast iron, and similar materials are the primary users.

This drill bit is suited for CNC machining centers, drill presses, and manual mills where tight-tolerance small-diameter holes are required. The 4xD flute-to-diameter ratio and 10.9 mm maximum drilling depth make it appropriate for shallow to moderate depth holes in production and job-shop environments. The straight-cylindrical shank with a 3 mm shank diameter seats securely in standard collets and drill chucks. It performs well in ferrous and non-ferrous metals where heat generation and tool wear are primary concerns.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and extended tool life at high surface speeds
• 140-degree notched point for self-centering entry and reduced walking on entry
• Web-thinned parallel web reduces axial cutting force and improves chip flow
• Right-hand regular spiral flutes for efficient chip evacuation
• Straight-cylindrical shank fits standard collets and keyless chucks without adapters

Compatibility

Designed as an OEM-style high-performance replacement or direct-use jobber drill bit for applications requiring a 2 mm diameter, straight-shank carbide drill with AlTiN coating.

Installation Notes

Install in a properly sized collet or drill chuck sized for a 3 mm shank before powering the machine. Verify runout with a dial indicator before beginning production drilling to avoid premature tool breakage at this small diameter. Follow machine manufacturer feed and speed recommendations for solid carbide tooling in the workpiece material. Secure the workpiece fully before starting the cut — lateral movement at 2 mm diameter will snap the bit.
