Seco 02897913 Solid Carbide Jobber Drill Bit 8 Mm

Product Description

The SECO 02897913 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and hard materials. Built to Series SD1105A specifications, it features an AlCrN coating, a 140-degree split-point geometry, and a straight-cylindrical shank measuring 8 mm in diameter. The two-flute spiral design promotes efficient chip evacuation during drilling operations. With an overall length of 3.59 inches and a flute length of 2.09 inches, this bit handles drilling depths up to 2.09 inches. It is sized to an m7 diameter tolerance, making it suitable for precise-fit hole requirements. Licensed machinists, tool-and-die tradespeople, and CNC operators are the primary installers.

This drill bit is rated for use in steel, stainless steel, cast iron, and other hard materials, corresponding to ISO material codes P, M, K, and H. The 7xD flute-to-diameter ratio supports moderately deep hole drilling in a jobber-length format. It is well suited for production drilling environments, job shop work, and maintenance applications where consistent hole quality in ferrous and hard workpiece materials is required. The right-hand cut and standard point type make it compatible with conventional drill press, milling machine, and CNC machining center spindles.

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 split-point geometry reduces thrust force and improves self-centering
• Two-flute regular spiral design promotes consistent chip removal
• Straight-cylindrical shank compatible with standard collets and drill chucks
• m7 diameter tolerance supports precision-fit hole applications

Compatibility

Designed for use in standard drill press, CNC machining center, and milling machine setups with collet or chuck toolholding rated for 8 mm straight-cylindrical shanks. Suitable for workpiece materials including steel, stainless steel, cast iron, and other hard materials per ISO codes P, M, K, and H.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with speeds, feeds, and toolholding practices for solid carbide tooling. Secure the shank fully in a properly sized collet or drill chuck before operation, and verify runout is within acceptable limits before cutting. Solid carbide tooling is brittle — avoid side loading, interrupted cuts without appropriate feeds, or dropping the bit on hard surfaces. Follow the machine manufacturer and tooling supplier recommendations for cutting parameters based on workpiece material and machine rigidity.
