Kennametal 4149254 Solid Carbide Jobber Drill 8.10mm

Product Description

The KENNAMETAL 4149254 is a solid carbide jobber-length drill bit engineered for high-performance hole-making in demanding materials. It features a 140-degree point angle for fast penetration and reduced thrust, a multilayer TiAlN coating for heat resistance and extended tool life, and a right-hand regular spiral flute geometry. The 8.10 mm cutting diameter conforms to DIN 6537K standards. With an overall length of 103.00 mm and a flute length of 61.00 mm, this drill is suited for applications where tight tolerances and consistent hole quality are critical. Machinists and tool-and-die professionals rely on solid carbide construction for rigidity and wear resistance in production environments.

This drill is designed for use in CNC machining centers and drill presses where coolant-through capability can be utilized. It performs in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 5xD flute-to-diameter ratio supports moderate-depth drilling without chip packing. The straight cylindrical shank seats securely in standard drill chucks and collet holders. It is a practical choice for job shops and manufacturing operations running high-cycle programs that require repeatable results across multiple materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in production drilling
• Multilayer TiAlN coating provides thermal protection and extends cutting edge life
• 140-degree point angle reduces thrust and improves centering on entry
• Coolant-through design supports internal coolant delivery for deep-hole and high-speed applications
• Right-hand regular spiral flute geometry promotes efficient chip evacuation
• Conforms to DIN 6537K specification for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-fit solid carbide jobber drill conforming to DIN 6537K, suitable for use in standard straight-shank drill chucks and collet systems accepting a 10 mm shank diameter.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a full stop and lockout-tagout procedures completed. Ensure the straight cylindrical shank is fully seated and securely clamped in the chuck or collet before operation. When using coolant-through capability, verify that the machine spindle and toolholder are configured to deliver internal coolant at the appropriate pressure. Inspect the cutting edges for wear or chipping before each use and replace when diameter tolerance or surface finish begins to degrade.
