Kennametal 4149248 Solid Carbide Jobber Drill 7.60 Mm

Product Description

The KENNAMETAL 4149248 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding production environments. It features a 7.60 mm diameter with a 140-degree split point and a multilayer TiAlN coating that extends tool life by reducing heat buildup and improving wear resistance. The straight cylindrical shank measures 8 mm in diameter, and the overall length is 91.00 mm with a flute length of 53.00 mm. This bit is built to DIN 6537K specification and includes through-coolant capability, making it suitable for CNC machining centers and automated drilling operations where tool life and chip evacuation are critical. Licensed machinists and CNC operators are the primary users.

This drill is rated for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials, covering a wide range of industrial and maintenance machining applications. The 5xD flute-to-diameter ratio and regular spiral flute geometry support consistent chip removal in both through-hole and blind-hole applications. It fits within the 7.00 mm to 8.00 mm diameter range and is sized to work in standard drill chucks and collet holders that accommodate an 8 mm straight shank. Typical applications include structural fabrication shops, tool rooms, and production lines running ferrous and non-ferrous components.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• Multilayer TiAlN coating reduces thermal wear and improves performance in steel and stainless steel
• 140-degree point angle minimizes walk and reduces thrust force on entry
• Through-coolant design supports high-speed drilling and efficient chip evacuation
• Right-hand cutting with regular spiral flute geometry for reliable chip flow
• Meets DIN 6537K specification for consistent dimensional accuracy

Compatibility

Designed for use in CNC machining centers and drill presses equipped with collet chucks or drill chucks accepting an 8 mm straight cylindrical shank. Suitable for workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify that through-coolant lines are connected and pressure is set per machine specifications before initiating a drilling cycle. Do not exceed the maximum drilling depth of 43.00 mm without retracting to clear chips.
