Accupro 4500546 Taper Length Drill Bit 5 Mm Carbide

Product Description

The ACCUPRO 4500546 is a solid carbide taper length drill bit engineered for high-performance drilling in demanding materials. At 5 mm in diameter (0.1969 inches), it features a 140-degree split point and a TiAlN (titanium aluminum nitride) coating that extends tool life in abrasive and heat-intensive cutting conditions. The straight cylindrical shank seats securely in standard drill chucks or collet holders. Coolant-through capability allows cutting fluid to reach the cutting edge directly, reducing heat buildup and improving chip evacuation in deep-hole applications. This bit is suited to machinists, tool-and-die specialists, and precision fabricators working in production or job-shop environments.

This drill bit is optimized for stainless steel machining, where heat resistance and edge retention are critical. The 8xD flute-length-to-diameter ratio and spiral flute geometry support deep-hole drilling with consistent chip clearing. The R-thinned web reduces thrust force at the point, making it practical for manual and CNC drilling operations where controlled entry is important. It is sold and packaged as a single unit.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating provides thermal protection and extended tool life
• 140-degree point angle reduces thrust and improves centering on entry
• Coolant-through design delivers cutting fluid directly to the cutting zone
• R-thinned web lowers feed force and reduces chisel edge engagement
• 8xD flute-length-to-diameter ratio supports deep-hole applications

Compatibility

Rated for use in stainless steel applications. Compatible with standard straight-shank drill chucks and collet systems accepting a 6 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with drill press, lathe, or CNC machining center setups. Ensure the spindle and workpiece are fully secured before starting the cut. When using the coolant-through feature, verify that the machine spindle supports through-coolant delivery at an appropriate pressure for the material being drilled. Inspect the cutting edge for wear or chipping before each use, as carbide tooling can fracture if run in a damaged condition.
