Accupro 4500265 Solid Carbide Jobber Drill 6.90 Mm

Product Description

The ACCUPRO 4500265 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. Built with a 140-degree split point and TiAlN coating, it resists heat and wear in applications where standard HSS tooling falls short. The 6.90 mm diameter (0.2717 inch) bit features a right-hand cutting direction, regular spiral flutes, and an R-thinned web to reduce thrust and improve chip evacuation. Overall length is 91.00 mm (3.5827 inches) with a flute length of 53.00 mm (2.0866 inches). It is suited for machinists, tool-and-die technicians, and CNC operators working in production environments.

This drill bit is engineered for use in stainless steel and other difficult-to-machine ferrous and non-ferrous metals where heat generation and tool wear are primary concerns. The coolant-through design allows cutting fluid to reach the cutting edge directly, making it well suited for deep-hole drilling cycles on CNC machining centers and drill presses in both job shop and production settings. The 5xD flute-to-diameter ratio supports consistent chip flow in interrupted or continuous cuts.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating improves heat resistance and extends tool life in stainless steel applications
• 140-degree proprietary point angle reduces walking and minimizes breakthrough burr
• Coolant-through capability delivers cutting fluid directly to the cutting zone
• R-thinned web lowers drilling thrust and improves chip evacuation
• Right-hand, regular spiral flute geometry provides consistent chip flow
• Straight cylindrical shank fits standard drill chucks and hydraulic toolholders

Compatibility

Designed as a high-performance jobber drill for use in stainless steel and similar hard ferrous materials; shank diameter of 8 mm is compatible with standard drill chucks, collet holders, and hydraulic toolholding systems accepting straight-shank tooling in that size range.

Installation Notes

Installation and use should be performed by qualified machinists or CNC technicians familiar with carbide tooling handling procedures. Carbide is brittle — avoid dropping or side-loading the tool during setup. Confirm the toolholder runout is within acceptable tolerance before starting a cycle, as excessive runout will shorten tool life significantly. Activate coolant-through supply before engaging the cut when using the internal coolant feature.
