Kennametal 1913504 Carbide Drill Bit 1/2 Inch Tialn

Product Description

The KENNAMETAL 1913504 is a solid carbide screw machine length drill bit designed for high-productivity metal cutting in production and job-shop environments. Built to DIN 6537K standards, this bit features a 140-degree split point geometry with web thinning for reduced thrust force and improved chip evacuation at entry. The multilayer TiAlN coating provides heat resistance and extended tool life in abrasive materials. With a 0.5-inch cutting diameter and a compact 4.2126-inch overall length, it delivers rigidity and accuracy in short-reach drilling applications. Installed by machinists and tool-and-die technicians on CNC machining centers, drill presses, and automatic screw machines.

This drill bit is suited for production drilling in cast iron and steel workpieces where tight hole tolerances and consistent performance are required. The screw machine length design keeps the bit close to the spindle, reducing deflection during high-feed-rate operations. The straight cylindrical shank at 0.5512 inches in diameter seats securely in standard drill chucks and collet holders. Typical applications include through-hole drilling, stepped-hole preparation, and multi-part fixture runs in metalworking production settings.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Multilayer TiAlN coating for thermal resistance and extended tool life
• 140-degree standard point angle with web-thinned geometry reduces entry thrust
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Right-hand cutting, regular spiral flute for efficient chip removal
• Compact screw machine length minimizes deflection in short-reach drilling setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard drill chucks and collet systems accepting a 0.5512-inch straight cylindrical shank; primary workpiece materials are cast iron and steel per manufacturer specification.

Installation Notes

Installation and tool changes should be performed with the machine powered down and the spindle fully stopped. Secure the straight shank firmly in a properly sized drill chuck or collet to the chuck manufacturer's recommended torque specification. Verify spindle runout before production use, as carbide is brittle and sensitive to lateral loading. Consult applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when drilling cast iron or steel.
