Accupro 4500495 Taper Length Drill Bit 10 Mm Carbide

Product Description

The ACCUPRO 4500495 is a solid carbide taper length drill bit engineered for demanding metal cutting applications. Built from solid carbide with a TiAlN coating, it delivers extended tool life and heat resistance in high-speed drilling operations. The bit features a 140-degree point angle with R-thinned web geometry, which reduces thrust and improves chip evacuation at entry. A right-hand spiral flute in a regular helix configuration clears chips efficiently throughout the cut. At 10 mm in diameter with an 8xD flute-to-diameter ratio, this drill is suited for deeper hole applications where standard-length bits fall short. Machinists and tool-and-die professionals are the primary installers of this tooling.

This drill bit is designed for cutting stainless steel and other difficult-to-machine materials where tool hardness and coating performance are critical. The coolant-through design allows cutting fluid to be delivered directly to the cutting edge, reducing heat buildup and extending tool life in deep-hole operations. It is well suited for CNC machining centers and manual knee mills where consistent, repeatable hole quality is required. The straight cylindrical shank fits standard collet chucks, drill chucks, and hydraulic toolholders sized for 10 mm shanks.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard material applications
• TiAlN coating improves heat resistance and extends tool life at elevated cutting speeds
• 140-degree point angle reduces thrust and is optimized for stainless steel entry
• R-thinned web lowers cutting forces and improves self-centering at the start of the cut
• Coolant-through design delivers fluid directly to the cutting zone in deep-hole drilling
• 8xD flute length ratio supports deeper hole depths than jobber-length alternatives

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 10 mm collet chucks, drill chucks, or hydraulic toolholders accepting straight cylindrical shanks. Optimized for stainless steel material applications as specified by the manufacturer.

Installation Notes

Installation and use of this tooling should be performed by qualified machinists familiar with speeds, feeds, and toolholder requirements for solid carbide drills. Ensure the machine spindle and toolholder are clean and free of runout before seating the shank. When using the coolant-through feature, verify that coolant pressure and flow rate are compatible with the machine spindle. Inspect the cutting edges for chipping before each use, as carbide is brittle and sensitive to interrupted cuts or improper handling.
