Accupro 4500193 Solid Carbide Jobber Drill 5.80mm Tialn

Product Description

The ACCUPRO 4500193 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. It features a 140-degree split point geometry with R-thinned web for reduced thrust and improved chip evacuation. The TiAlN coating adds heat and wear resistance, making the bit well suited for dry or near-dry cutting conditions. With a 5.80 mm diameter and 82.00 mm overall length, it fits standard CNC machining centers, drill presses, and manual machines where precision hole-making in tough alloys is required. Machinists, tool-and-die makers, and manufacturing technicians are the primary users.

This drill bit is built for use in stainless steel and other hard ferrous materials where tool longevity and hole quality are critical. The 5xD flute-to-diameter ratio supports chip clearance in deeper holes. Its straight cylindrical shank with a 6 mm diameter seats into standard collet chucks and drill chucks without modification. Typical applications include production machining, maintenance repair operations, and precision fabrication work where carbide outperforms high-speed steel in both life and finish quality.

Key Features

• Solid carbide construction for superior hardness and wear resistance in stainless steel and hard alloys
• TiAlN coating improves thermal resistance and extends tool life in dry or minimal-lubrication cutting
• 140-degree point angle reduces walking and exit burr on hard, work-hardening materials
• R-thinned web lowers drilling thrust and improves chip flow
• Coolant-through design supports internal coolant delivery for deep-hole applications
• Regular spiral flute with 5xD ratio maintains chip evacuation in deeper cuts

Compatibility

Designed as a standard jobber-length replacement drill for use in CNC machining centers, drill presses, and other machine tool spindles accepting a 6 mm straight cylindrical shank. Conforms to DIN specification standards.

Installation Notes

This bit is installed by a machinist or toolroom technician into a collet chuck, keyless chuck, or hydraulic chuck rated for the 6 mm shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator before production use, as carbide is sensitive to lateral loading from misalignment. Follow shop-specific speeds and feeds for the workpiece material and consult the DIN specification for tolerance class guidance.
