Seco 03046003 Screw Machine Drill Bit 10mm Carbide

Product Description

The SECO 03046003 is a solid carbide screw machine length drill bit designed for high-performance drilling in steel and other demanding workpiece materials. It features a 10.00 mm diameter, a 140-degree cone relief point, and a TiAlN coating that supports heat resistance and extended tool life. The overall length is 89.00 mm with a 47.00 mm flute length and a 40.00 mm straight cylindrical shank. Web thinning reduces thrust force at entry and improves chip evacuation. Coolant-through capability allows internal coolant delivery directly to the cutting zone, supporting higher feed rates and longer tool life in production environments.

This drill bit is suited for production machining and precision drilling operations in steel. The screw machine length format provides a rigid, compact profile that reduces deflection in short-reach applications. It is appropriate for use in CNC machining centers, drill presses, and screw machine setups where consistent hole quality and dimensional accuracy are required. The SD203A series follows DIN standards and carries an m7 shank diameter tolerance, making it compatible with standard precision toolholders and collet chucks.

Key Features

• Solid carbide construction for rigidity and wear resistance in steel cutting
• TiAlN coating for elevated heat resistance and extended tool life
• 140-degree cone relief point reduces thrust and improves centering
• Coolant-through design delivers coolant directly to the cutting edge
• Web-thinned geometry reduces entry force and improves chip flow
• Screw machine length format provides a compact, low-deflection profile

Compatibility

Designed as an OEM-style replacement or direct-use tool in machining setups requiring a 10.00 mm screw machine length drill bit conforming to DIN standards with an m7 shank tolerance. Primary workpiece material is steel.

Installation Notes

This tool is installed and serviced by machinists and CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Seat the straight shank fully and securely in the collet or toolholder to the specified grip depth to prevent pullout under load. Verify coolant-through passages are clear and coolant supply is active before beginning production drilling cycles.
