Accupro 4500283 Jobber Drill 9mm Solid Carbide Tialn

Product Description

The ACCUPRO 4500283 is a solid carbide jobber-length drill bit engineered for high-performance metal cutting in demanding production environments. It measures 9.00 mm (0.3543 inches) in diameter with a 140-degree proprietary point angle that reduces thrust and improves centering on hard materials. The TiAlN coating extends tool life by resisting heat buildup at elevated cutting speeds. Two regular spiral flutes evacuate chips efficiently, and the R-thinned web reduces cutting force at entry. Coolant-through capability makes this bit well suited for deep-hole operations where heat and chip management are critical. The straight cylindrical shank seats securely in standard drill chucks and collet holders.

This bit is designed for drilling stainless steel and other hard ferrous materials in CNC machining centers, drill presses, and production drilling setups. The 5xD flute-to-diameter ratio and right-hand cutting direction make it a standard fit for high-cycle production work where tool consistency matters. Machinists, toolroom technicians, and production operators working with stainless, alloy steel, or other difficult-to-machine metals will find this bit suited to their applications.

Key Features

• 9.00 mm diameter solid carbide construction for rigidity and heat resistance
• TiAlN coating for extended tool life in high-temperature cutting conditions
• 140-degree proprietary point angle for reduced thrust and accurate entry
• Coolant-through design supports deep-hole drilling and chip flushing
• R-thinned web reduces cutting force at the point
• DIN specification compliance for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement or standard tooling option for applications requiring a 9.00 mm straight-shank jobber drill in CNC or manual drilling equipment with a 10 mm shank bore.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm the collet or chuck bore accommodates the 10 mm straight shank before seating the bit. When using coolant-through capability, verify that coolant pressure and flow rate are appropriate for the machine spindle before operation.
