Kennametal 4149351 Solid Carbide Jobber Drill 19/32 in

Product Description

The KENNAMETAL 4149351 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding production environments. It features a 19/32 inch (0.5938 inch) diameter with a 140-degree point angle and a multilayer TiAlN coating that extends tool life in abrasive and heat-generating applications. The drill measures 5.2362 inches overall length with a 3.2677-inch flute length, and runs a right-hand, regular spiral flute configuration. This is a professional-grade cutting tool installed by machinists and toolroom technicians in CNC and manual drilling operations.

This jobber drill is suited for production drilling in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 5xD flute-to-diameter ratio and coolant-through design make it well matched to deep-hole drilling cycles where chip evacuation and heat management are critical. The straight cylindrical shank fits standard drill chucks and collet holders. It conforms to DIN 6537K specification, making it a recognized standard for tooling applications across manufacturing and fabrication shops.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• Multilayer TiAlN coating reduces heat buildup and extends cutting edge life
• 140-degree point angle improves centering and reduces thrust force on entry
• Coolant-through design supports chip evacuation and thermal control in deep-hole drilling
• Right-hand, regular spiral flute with tapered web configuration for consistent chip flow
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed for use in steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials. The straight cylindrical shank is compatible with standard drill chucks and collet-style tool holders accepting a 0.2969-inch shank diameter.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill. Verify chuck or collet runout is within tolerance before starting a drilling cycle, as excessive runout will accelerate edge wear on carbide tooling. Follow machine tool manufacturer guidelines for feed rate and spindle speed when drilling the specified workpiece materials.
