Accupro 4500267 Solid Carbide Jobber Drill 6.40 Mm Tialn

Product Description

The ACCUPRO 4500267 is a solid carbide jobber-length drill designed for high-performance drilling in demanding metalworking and machining applications. Built to DIN specification, it features a 140-degree split point with R-thinning for reduced thrust and improved self-centering on entry. The TiAlN coating extends tool life at elevated cutting temperatures, making it well-suited for dry or minimal-lubrication operations. At 6.40 mm in diameter with a 91 mm overall length, this two-flute right-hand spiral drill delivers consistent chip evacuation through regular spiral flutes. Coolant-through capability supports high-speed setups where internal coolant delivery is available.

This drill is intended for use in CNC machining centers, drill presses, and manual machines where tight tolerances and repeatable hole quality are required. It fits into setups targeting the 6.00 to 7.00 mm diameter range and is appropriate for production work in steel, stainless steel, cast iron, and other ferrous and hard alloy workpieces. The straight cylindrical shank seats in standard collet chucks, drill chucks, and hydraulic tool holders. Machinists, tool-and-die technicians, and CNC operators are the primary users.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating for heat resistance and extended tool life at high cutting speeds
• 140-degree proprietary split point with R-thinning reduces walking and entry thrust
• Coolant-through design supports internal coolant delivery for deep-hole and high-feed applications
• Regular spiral flute geometry promotes reliable chip evacuation in through-hole drilling
• DIN specification compliance ensures consistent dimensional standards

Compatibility

Designed as a high-performance replacement jobber drill for machining setups requiring a 6.40 mm diameter solid carbide tool with a straight cylindrical shank in the 6.00 to 7.00 mm size range.

Installation Notes

Installation is performed by machinists and CNC operators following standard tool-change procedures. Power down or lock out the spindle before seating or removing the tool. Ensure the straight shank is clean and fully seated in the collet or chuck to the recommended grip length before tightening. Verify spindle speed and feed rate are set to values appropriate for the workpiece material and tool diameter before starting the cut.
