Seco 02897874 Solid Carbide Jobber Drill 5.10mm 140deg

Product Description

The SECO 02897874 is a solid carbide jobber-length drill bit from the SD1105A series, designed for high-performance drilling in demanding production and maintenance environments. It carries an AlCrN (aluminum chromium nitride) coating that improves heat resistance and extends tool life when cutting hard and abrasive materials. The drill measures 5.10 mm (0.2009 inches) in diameter with a 140-degree point angle suited for fast chip penetration and reduced thrust. Overall length is 82.00 mm (3.2308 inches) with a flute length of 44.00 mm (1.7336 inches). Installation is performed by machinists, tool-and-die technicians, and maintenance trades.

This drill bit is engineered for right-hand cutting in steel, stainless steel, cast iron, and other hard materials classified under ISO material groups P, M, K, and H. The 7xD flute-to-diameter ratio and regular spiral flute geometry promote consistent chip evacuation in these materials. The straight-cylindrical shank measures 6.00 mm (0.2364 inches) in diameter and 36.00 mm (1.4184 inches) in length, making it compatible with standard drill chucks and collet holders used in CNC machining centers, drill presses, and hand-held power tools. Maximum drilling depth is 35.00 mm (1.7336 inches).

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material applications
• AlCrN coating increases surface hardness and thermal stability at the cutting edge
• 140-degree point angle reduces thrust load and improves self-centering on entry
• Regular spiral, 2-flute design promotes reliable chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet systems without adapters
• Meets ANSI standards; diameter tolerance rated m7 for consistent fit and repeatable hole quality

Compatibility

Designed for use in steel, stainless steel, cast iron, and hard materials (ISO groups P, M, K, H). The 6.00 mm straight-cylindrical shank fits standard drill chucks and collet holders across CNC machining centers, drill presses, and handheld drilling equipment. Drill bit size falls within the 5.00 mm to 6.00 mm (0.2000 to 0.2500 inch) range of the SD1105A series.

Installation Notes

This drill bit is installed and operated by machinists, maintenance technicians, and metalworking trades. Before mounting, ensure the spindle or chuck is fully de-energized and locked out per site lockout/tagout procedures. Secure the shank firmly in the chuck or collet to the manufacturer-specified clamping depth to prevent slippage during cutting. Do not exceed the maximum drilling depth of 35.00 mm, and use appropriate cutting fluid or coolant for the workpiece material when possible to preserve coating and edge integrity.
