Kennametal 4112630 Carbide Jobber Drill Bit 7mm 135 Deg

Product Description

The KENNAMETAL 4112630 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. Built to DIN 6537K specification, it features a multilayer TiAlN coating that extends tool life in abrasive and high-temperature cutting conditions. The 135-degree split-point geometry reduces entry force and minimizes walking on flat or curved surfaces. At 7 mm in diameter with a straight-cylindrical shank measuring 8 mm, this bit fits standard collet chucks and drill holders across CNC machining centers and manual drill presses. Coolant-through capability supports chip evacuation and heat management during deep-hole operations.

This drill bit is suited for production machining environments where tight tolerances and consistent hole quality are required. The 5xD flute-to-diameter ratio and 91 mm overall length make it appropriate for structural steel, stainless, cast iron, and hardened alloy applications. It is typically installed by machinists and tool-and-die professionals working in job shops, aerospace, automotive, and general manufacturing. The KCPK15 material grade is optimized for hard and abrasive workpiece materials.

Key Features

• Solid carbide construction in material grade KCPK15 for hardness and wear resistance
• Multilayer TiAlN coating improves heat resistance and tool life in abrasive materials
• 135-degree standard point angle reduces thrust force and prevents bit walk
• Coolant-through design for effective chip removal and thermal control in deep holes
• Straight-cylindrical shank for compatibility with standard collet and drill chuck systems
• Tapered web configuration maintains core strength along the full flute length

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual drill presses accepting straight-cylindrical shank drill bits with an 8 mm shank diameter, conforming to DIN 6537K specification.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the collet or drill chuck to the manufacturer-specified engagement depth before operation. Ensure the machine spindle is fully stopped and locked out before changing or inspecting tooling. Verify coolant-through passages are clear and supply pressure is set according to the machine tool specifications before drilling operations begin.
