Seco 02897863 Solid Carbide Jobber Drill Bit 4.3 Mm

Product Description

The SECO 02897863 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding materials. It carries an AlCrN coating and a 140-degree split point, delivering clean entry and reduced thrust in steel, stainless steel, cast iron, and other hard materials. The straight-cylindrical shank measures 6.00 mm in diameter and fits standard drill chucks without adapters. Overall length is 74.00 mm (approximately 2.92 inches) with a flute length of 36.00 mm (approximately 1.42 inches). This bit belongs to SECO Series SD1105A and is rated as a high-performance cutting tool intended for professional machining and fabrication environments.

This drill bit is suited for production drilling in machine shops, job shops, and fabrication facilities where close-tolerance hole quality in hard workpiece materials is required. It targets applications in steel (ISO P), stainless steel (ISO M), cast iron (ISO K), and hard materials (ISO H). The 6xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. It is designed for use in CNC machining centers, drill presses, and handheld power tools with compatible chuck capacities. No coolant-through capability is present, so external coolant or cutting fluid should be applied at the workpiece when drilling hard or heat-sensitive alloys.

Key Features

• Solid carbide construction with AlCrN coating for heat and wear resistance in hard materials
• 140-degree point angle reduces thrust and improves self-centering on entry
• Right-hand spiral flute with regular helix promotes chip clearance in through and blind holes
• Straight-cylindrical 6.00 mm shank fits standard drill chucks with no adapter required
• 6xD flute-by-diameter ratio supports drilling to a maximum depth of 29.00 mm (approximately 1.42 inches)
• Meets ANSI specification standards; diameter tolerance class m7 for consistent fit

Compatibility

Designed for drilling steel, stainless steel, cast iron, and hard materials (ISO P, M, K, H workpiece classifications) as specified for Series SD1105A. Compatible with any machine or hand tool accepting a straight-cylindrical 6.00 mm shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Because this bit has no internal coolant channel, apply external cutting fluid or coolant directly to the drill point when working hard or stainless materials to prevent heat buildup. Inspect the cutting edges before each use and remove the bit from service if chipping or coating wear is observed.
