Seco 03046001 Screw Machine Drill Bit 9.80mm Carbide

Product Description

The SECO 03046001 is a screw machine length drill bit engineered for high-performance drilling in steel and similar ferrous workpiece materials. Built from solid carbide and coated with TiAlN for heat and wear resistance, it features a 140-degree cone relief point and a web-thinned tip geometry that reduces thrust and improves centering at entry. The 9.80 mm diameter cutting edge, two regular spiral flutes, and coolant-through capability make this bit well-suited to demanding production environments where cycle time and tool life are critical. Overall length is 89.00 mm (3.50 inches), with a 47.00 mm flute length and a maximum drilling depth of 35.00 mm.

This drill bit is intended for use in CNC machining centers, drill presses, and turret lathes where a short, rigid stub-length tool is preferred. The straight cylindrical shank at 10.00 mm diameter fits standard collet chucks and hydraulic holders commonly used in metal fabrication and precision machining shops. Its Series SD203A designation places it within a consistent family of screw machine length carbide drills sized for high-volume hole-making operations. Primary application is drilling steel, though the TiAlN coating supports use in a range of ferrous alloys. Installation and operation should be performed by qualified machinists familiar with carbide tooling practices.

Key Features

• Solid carbide construction for rigidity and long tool life in steel applications
• TiAlN coating improves heat resistance and extends wear life at higher cutting speeds
• 140-degree cone relief point with web thinning reduces entry thrust and improves hole accuracy
• Coolant-through design delivers cutting fluid directly to the cutting edge for chip evacuation and thermal control
• Screw machine (stub) length body increases rigidity and reduces deflection compared to jobber-length drills
• Straight cylindrical shank compatible with standard collet chucks and hydraulic tool holders
• Manufactured to DIN standards with m7 diameter tolerance for consistent fit and repeatability

Compatibility

Designed as an OEM-style screw machine length carbide drill for use in CNC machining centers and drill presses equipped with standard collet or hydraulic chuck systems accepting a 10.00 mm straight shank. Sized within the 9.50 mm to 11.00 mm drill diameter range of the SD203A series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. Carbide drills are brittle and should never be used in hand-held drilling applications or subjected to side loads. Confirm chuck runout is within acceptable limits before use, as excessive runout accelerates edge chipping on carbide tooling. Enable coolant-through flow before engaging the cut to protect the tool and workpiece.
