Kennametal 1191433 Solid Carbide Jobber Drill 7mm 130 Deg

Product Description

The KENNAMETAL 1191433 is a solid carbide jobber-length drill designed for precision hole-making in demanding materials. The 7.00 mm cutting diameter pairs with a 130-degree split point and web-thinned geometry to deliver clean entry and reduced thrust force. Three regular spiral flutes evacuate chips efficiently, keeping the cutting zone clear during extended runs. The straight cylindrical shank measures 8 mm in diameter, making it compatible with standard drill chucks and collet holders. Built to DIN 6537L standards, this drill is intended for use by machinists, toolroom technicians, and production drilling operations requiring tight diameter tolerances.

This drill is suited for production and job-shop applications involving cast iron, aluminum and other non-ferrous metals, and high-temperature alloys. The bright uncoated finish and K10 carbide grade are well matched to non-ferrous and cast materials where coating adhesion or heat buildup is less of a concern. The tapered web configuration and web-thinned point help maintain accuracy in both manual and CNC-controlled drilling setups. Maximum recommended drilling depth is 43.00 mm, keeping it within the effective flute length for reliable chip clearance.

Key Features

• Solid carbide K10 grade construction for rigidity and wear resistance in abrasive materials
• 130-degree standard point angle with web thinning reduces entry thrust and improves centering
• Three-flute regular spiral design improves chip evacuation compared to standard two-flute geometry
• Bright uncoated finish suited for aluminum, non-ferrous metals, and cast iron
• Conforms to DIN 6537L specification for consistent dimensional accuracy
• Diameter tolerance of 0.006 to 0.021 mm supports precision bore applications

Compatibility

Designed for use with standard drill chucks and collet systems accepting an 8 mm straight cylindrical shank. Primary workpiece materials per manufacturer specification are cast iron, aluminum and non-ferrous metals, and high-temperature alloys. Fits within the DIN 6537L jobber drill series.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Secure the shank fully in a properly sized chuck or collet before operation and verify runout before beginning a cut. Carbide drills are brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper setup, or re-chucking at an angle. Follow machine-tool manufacturer guidelines and applicable shop safety protocols when operating at drilling speeds appropriate for carbide in the target workpiece material.
