Accupro 50369 Jobber Drill Bit Wire 7 Altin Solid Carbide

Product Description

The ACCUPRO 50369 is a solid carbide jobber-length drill bit designed for precision hole-making in hard and abrasive materials. Sized to wire gauge number 7, it has a decimal diameter of 0.2010 inches and features an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life in demanding cutting applications. The 150-degree drill point angle reduces thrust and improves chip evacuation when entering harder workpieces. With a 3-inch overall length and a 3-flute spiral configuration, this bit is suited for use in CNC machining centers and high-performance drill presses in metalworking and fabrication environments. It is installed and used by machinists and tool-and-die professionals.

This bit is intended for dry or light-lubrication drilling operations in hard metals, hardened steels, stainless, and similar alloys where high-speed steel tooling wears prematurely. The solid carbide substrate combined with the AlTiN coating makes it appropriate for production drilling in aerospace, automotive, and precision machined-parts manufacturing. It is a jobber-length format, making it compatible with standard drill chucks and collet holders found on most machining equipment. Coolant-through is not supported on this model.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves oxidation resistance and reduces heat buildup at the cutting edge
• 150-degree drill point angle reduces entry thrust and improves chip clearing
• 3-flute spiral design increases cutting efficiency and chip evacuation compared to 2-flute geometry
• Right-hand cutting direction with regular spiral type for standard CNC and manual drill applications
• Straight cylindrical shank fits standard drill chucks and ER collet holders

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard drill chucks and collet systems accepting a straight cylindrical shank at 0.2010 inches diameter, conforming to ANSI specification designation.

Installation Notes

Solid carbide drill bits are installed by machinists in CNC machining centers, drill presses, or manual mills using a properly sized collet or chuck. Ensure the shank is fully seated and the holder is torqued to equipment manufacturer specifications before operation. Solid carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without appropriate feed rate adjustments, or dropping the tool. Inspect the cutting edge for chipping before each use.
