Seco 02897872 Solid Carbide Jobber Drill 5.80 Mm Alcrn

Product Description

The SECO 02897872 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding workpiece materials. It features a 5.80 mm cutting diameter, a 140-degree split point for precise entry and reduced walking, and an AlCrN (aluminum chromium nitride) coating that extends tool life in abrasive and hard materials. The overall length is 82.00 mm (3.23 inches) with a straight-cylindrical shank diameter of 6.00 mm. Right-hand spiral flutes in a regular helix pattern evacuate chips efficiently during through-hole and blind-hole operations. This bit belongs to the SD1105A series and is intended for use by machinists and tooling professionals on CNC machining centers and drill presses.

The 02897872 is engineered for drilling steel, stainless steel, cast iron, and hard materials, corresponding to ISO material groups P, M, K, and H. The 7xD flute-to-diameter ratio and 44.00 mm (1.73 inches) flute length support drilling depths up to 35.00 mm (1.73 inches). The straight-cylindrical shank seats directly into standard collet chucks and drill chucks without requiring an adapter. It is suited to production and maintenance environments where consistent hole quality and dimensional accuracy in hard metals are required.

Key Features

• 5.80 mm cutting diameter with m7 diameter tolerance for close-fit hole accuracy
• 140-degree standard point geometry reduces thrust force and improves self-centering
• AlCrN coating improves wear resistance and heat resistance in steel and hard materials
• Solid carbide construction provides rigidity superior to high-speed steel in hard and abrasive materials
• Right-hand, regular spiral flutes promote efficient chip evacuation
• Straight-cylindrical 6.00 mm shank is compatible with standard collet and drill chuck toolholders
• Coolant-through: No — suited for dry or external coolant applications

Compatibility

The SD1105A series is rated for ISO material groups P (steel), M (stainless steel), K (cast iron), and H (hard materials). Designed to seat in standard straight-bore collet chucks and drill chucks accepting a 6.00 mm shank diameter. Conforms to ANSI standards.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with CNC machining centers and manual drill presses. Secure the shank fully within the toolholder to the recommended engagement depth before operation, and confirm chuck or collet runout is within acceptable limits to avoid premature edge wear. Power down and de-energize the machine spindle before changing tooling. Do not exceed the maximum drilling depth of 35.00 mm per the flute length specification, and apply appropriate cutting speeds and feeds for the target workpiece material per the manufacturer's application data.
