Seco 02898020 Solid Carbide Jobber Drill 16.70mm 140deg

Product Description

The SECO 02898020 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding materials. Sized at 16.70 mm (0.658 inches) in diameter with a 140-degree point angle, this drill delivers accurate entry and reduced thrust in hard and abrasive workpiece materials. The AlCrN (aluminum chromium nitride) coating provides elevated heat and wear resistance, extending tool life in production environments. With an overall length of 143.00 mm (5.634 inches) and a regular spiral flute design, it maintains chip evacuation efficiency across a 5xD depth capacity. Installation is carried out by machinists and tool-room technicians working on CNC or manual drilling equipment.

The 02898020 is suited for drilling steel, stainless steel, cast iron, and other hard materials classified under ISO material groups P, M, K, and H. The straight-cylindrical shank (18.00 mm diameter) mounts directly into standard drill chucks or collet holders without adapters. A two-flute, right-hand spiral configuration promotes consistent chip flow and stable cutting action. This drill is part of the SECO SD1105A series and conforms to ANSI standards, making it appropriate for job-shop, aerospace, and general manufacturing environments where close-tolerance hole quality is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlCrN coating for enhanced heat resistance and extended tool life in steel and stainless steel
• 140-degree point angle reduces thrust and improves self-centering on entry
• Regular right-hand spiral flutes support efficient chip evacuation at 5xD depth
• Straight-cylindrical shank (18.00 mm) compatible with standard drill chucks and collet systems
• ANSI-compliant tolerances with m7 diameter tolerance for consistent hole sizing

Compatibility

Designed for use in CNC machining centers and manual drilling machines that accept straight-cylindrical shank tooling with an 18.00 mm shank diameter. Suited for primary workpiece materials including steel, stainless steel, cast iron, and hard materials (ISO groups P, M, K, H). Part of the SECO SD1105A series.

Installation Notes

This drill bit is installed and operated by qualified machinists or tool-room technicians. Ensure the machine spindle and chuck or collet are fully de-energized and at rest before mounting or removing the tool. Verify shank seating and runout before beginning a drilling cycle, as excessive runout accelerates edge wear and reduces hole accuracy. Always follow the machine tool manufacturer guidelines and applicable workplace safety codes when setting speeds and feeds for carbide tooling.
