Kennametal 4150829 Solid Carbide Jobber Drill 11/16 in

Product Description

The KENNAMETAL 4150829 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and non-ferrous materials. Built to DIN 6537K specification, it features a 140-degree point angle for improved self-centering and reduced thrust in hard materials. The multilayer TiAlN coating delivers heat resistance and extended tool life in demanding cutting environments. At 5.6299 inches overall length with a 3.6614-inch flute length, this drill handles depths up to 2.7953 inches. The straight cylindrical shank measures 0.5000 inches in diameter and seats securely in standard drill chucks and tool holders. Licensed machinists, CNC operators, and tool-and-die professionals are the primary users of this bit.

This drill is rated for primary workpiece materials including steel, stainless steel, cast iron, aluminum, and other non-ferrous metals, making it suitable for general machining, mold and die work, and production drilling on CNC machining centers or manual drill presses. The 5xD flute-by-diameter ratio and regular spiral flute geometry support consistent chip evacuation in typical through-hole and blind-hole applications. Coolant-through is not supported on this model, so external coolant or cutting fluid should be used when appropriate for the workpiece material.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Multilayer TiAlN coating for thermal protection and extended tool life
• 140-degree point angle reduces thrust and improves centering on entry
• DIN 6537K specification ensures dimensional consistency with standard tooling systems
• Regular spiral flute with tapered web configuration for controlled chip flow
• Right-hand cutting direction, compatible with standard spindle rotation

Compatibility

Designed for use with standard straight-shank tool holders and drill chucks accepting a 0.5000-inch shank diameter. Rated for steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials per manufacturer specification. Conforms to DIN 6537K.

Installation Notes

Installation and tool changes should be performed with the machine powered down and locked out per applicable safety procedures. Secure the straight shank fully within the chuck or collet to the recommended engagement depth before operation. Do not use this bit without appropriate workholding and chip management for the workpiece material. External cutting fluid or coolant is recommended, as this model does not support coolant-through delivery.
