Accupro 4500410 Screw Machine Drill Bit 10.80mm Carbide

Product Description

The ACCUPRO 4500410 is a screw machine length drill bit engineered for high-performance drilling in demanding metal-cutting applications. Built from solid carbide and coated with TiAlN, it delivers the hardness and heat resistance required when cutting through stainless steels and other difficult materials. The 140-degree web-thinned point reduces entry force and improves centering accuracy. At 10.80 mm in diameter with a 12.00 mm straight cylindrical shank, this bit fits standard collet and chuck setups. Coolant-through capability supports heat management during deep-hole operations, extending tool life in production environments. This is a professional-grade cutting tool intended for machinists, tool-and-die shops, and maintenance technicians working with CNC or manual drill presses.

The 4500410 is optimized for drilling stainless steels, making it well suited for fabrication shops, aerospace maintenance, food equipment manufacturing, and industrial MRO applications where work hardening is a concern. The TiAlN coating maintains hardness at elevated temperatures, which is critical when spindle speeds and feed rates push cutting edges hard. The 3xD flute-to-diameter ratio and regular spiral flute geometry provide efficient chip evacuation in short-hole screw machine length drilling scenarios. It follows DIN specification standards, making it compatible with metric tooling setups common in industrial production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material drilling
• TiAlN coating extends tool life by reducing heat buildup at the cutting edge
• 140-degree web-thinned point improves self-centering and reduces thrust force
• Coolant-through design supports chip flushing and thermal control in deep-hole applications
• Right-hand cutting, regular spiral flute for consistent chip evacuation
• DIN specification designation ensures dimensional conformance with metric tooling standards

Compatibility

Designed for use in CNC machining centers, drill presses, and screw machines equipped with collets or chucks accepting a 12.00 mm straight cylindrical shank. Optimized for primary workpiece material of stainless steels. Falls within the ACCUPRO ASSC140-TA-CL series for 9.50 mm to 11.00 mm diameter range tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm shank runout is within acceptable tolerance before beginning cuts, as carbide tooling is sensitive to lateral loading. When using the coolant-through feature, verify that coolant supply lines are connected and pressure is set according to the machine tool manufacturer's guidelines before initiating the drilling cycle.
