Kennametal 4149112 Solid Carbide Jobber Drill 10.20mm

Product Description

The KENNAMETAL 4149112 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding materials. It features a 10.20 mm diameter, a 140-degree point angle for reduced thrust and improved centering, and a multilayer TiAlN coating that extends tool life under elevated cutting temperatures. The straight cylindrical shank measures 12 mm in diameter, and the overall length is 118.00 mm (4.6457 inches). With coolant-through capability and a 5xD flute-to-diameter ratio, this drill is built for production environments where cycle time and tool life matter. It is typically installed by machinists and tool-room technicians working in CNC or manual drilling operations.

This drill is suited for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 140-degree point geometry performs well in hard-to-machine alloys and interrupted cuts. Coolant-through design supports chip evacuation and thermal management in deep-hole or high-feed applications. The DIN 6537K specification ensures dimensional consistency for use in standard toolholders and drill chucks accepting straight-shank tooling with a 12 mm shank diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive materials
• 140-degree point angle reduces entry thrust and improves self-centering
• Multilayer TiAlN coating extends tool life at elevated cutting speeds
• Coolant-through channels support chip evacuation and heat management
• Right-hand cutting with regular spiral flutes and tapered web configuration
• Meets DIN 6537K specification for dimensional consistency

Compatibility

Designed as an OEM-specification replacement or direct-fit solid carbide jobber drill for toolholders and drill chucks accepting a 12 mm straight cylindrical shank, conforming to DIN 6537K.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the straight shank in a compatible collet chuck or drill chuck to the manufacturer-recommended clamping torque for the holder in use. Verify spindle runout before beginning production drilling. Always disengage the spindle and confirm the machine is in a safe state before inserting or removing the tool.
