Kennametal 4149162 Jobber Drill No 36 Solid Carbide

Product Description

The KENNAMETAL 4149162 is a solid carbide jobber-length drill bit ground to No. 36 wire gauge size, which equals 0.1065 inches in diameter. It features a 140-degree split-point geometry for fast engagement and reduced walking on entry. The multilayer TiAlN coating supports high-heat resistance during aggressive drilling cycles. With an overall length of 2.2835 inches and a right-hand spiral flute, this drill is built for production environments where precision and tool life matter. It ships individually and is intended for use by machinists and tool-and-die professionals working on CNC or manual drilling operations.

This drill is designed for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. Its 5xD flute-to-diameter ratio and coolant-through construction make it well suited for deeper hole applications in tight-tolerance work. The straight cylindrical shank fits standard drill chucks and collet holders. It conforms to DIN 6537K specification, which governs carbide stub and jobber drills used in industrial production settings. Typical applications include precision hole drilling in metal fabrication, automotive components, and general machining where a wire-gauge hole diameter is called out on the print.

Key Features

• No. 36 wire size, 0.1065-inch diameter with a tolerance of -0.0006 to 0.0000 inches
• 140-degree standard point angle for clean entry and reduced thrust force
• Solid carbide construction with multilayer TiAlN coating for extended tool life in ferrous materials
• Coolant-through design supports chip evacuation and heat control at depth
• Right-hand, regular spiral flute with tapered web configuration
• Conforms to DIN 6537K specification

Compatibility

Designed as an OEM-style replacement or direct-fit solid carbide jobber drill for industrial drilling operations in steel, stainless steel, cast iron, aluminum, and non-ferrous materials requiring a No. 36 wire gauge hole diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling requirements. Secure the straight shank firmly in a compatible drill chuck or collet before operation, and verify runout is within acceptable limits to avoid chipping the carbide. Always engage the workpiece coolant system before drilling when using the coolant-through feature. Carbide drill bits are brittle compared to HSS — avoid side loading, interrupted cuts at high feed, or re-chucking a visibly chipped tool.
