Seco 02897910 Solid Carbide Jobber Drill 7.80 Mm 140 Deg

Product Description

The SECO 02897910 is a solid carbide jobber-length drill designed for high-performance drilling in demanding materials. It features a 7.80 mm diameter, a 140-degree standard point, and an AlCrN coating that extends tool life in abrasive and hard workpiece materials. The overall length is 91.00 mm (3.5854 inches) with a flute length of 53.00 mm (2.0882 inches). The straight-cylindrical shank measures 8.00 mm in diameter (0.3152 inches) and is compatible with standard drill chucks and collet holders. This drill is suited for metalworking operations where tool rigidity and heat resistance are critical. It is part of the SECO SD1105A series and conforms to ANSI standards.

This drill is intended for cutting steel, stainless steel, cast iron, and other hard materials, corresponding to ISO workpiece material codes P, M, K, and H. It is a right-hand cutting, spiral-flute design with a 7xD flute-to-diameter ratio and a maximum drilling depth of 43.00 mm (2.0882 inches). Typical applications include precision hole-making in machining centers, CNC drilling operations, and manual drill press setups where a solid carbide tool is required for harder material grades. No coolant-through capability is present on this drill.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlCrN coating improves heat resistance and extends tool life in steel and stainless steel
• 140-degree standard point angle reduces thrust force and improves self-centering
• Right-hand spiral flute with regular spiral type for efficient chip evacuation
• Straight-cylindrical shank fits standard chucks and collet toolholders
• ANSI-compliant dimensions in the SD1105A series for consistent interchangeability

Compatibility

Designed for use on steel, stainless steel, cast iron, and hard materials (ISO codes P, M, K, H). The straight-cylindrical shank fits standard drill chucks and collet holders accepting an 8.00 mm shank. This drill falls within the 7.00 mm to 8.00 mm drill bit size range of the SD1105A series.

Installation Notes

Installation is performed by machinists or CNC operators using appropriate toolholding equipment. Ensure the machine spindle and all toolholding components are clean and within tolerance before seating the shank. Solid carbide drills are brittle relative to HSS alternatives — avoid side loads, interrupted cuts without proper feeds and speeds, or excessive runout in the chuck, as these conditions can cause premature breakage. Follow the machine manufacturer and tooling manufacturer guidelines for recommended speeds and feeds for the specific workpiece material.
