Kennametal 4149361 Solid Carbide Jobber Drill 5/8 Inch

Product Description

The KENNAMETAL 4149361 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding materials. Built to DIN 6537K standards, it features a 5/8 inch (0.6250 inch) diameter, a 140-degree point angle, and a multilayer TiAlN coating that extends tool life under heat and abrasion. The 2-flute regular spiral geometry promotes chip evacuation in deep-hole applications. Coolant-through capability delivers cutting fluid directly to the tip, supporting consistent performance at depth. This drill is used by machinists and maintenance professionals working in steel, stainless steel, cast iron, and aluminum or non-ferrous alloys. Overall length is 5.2362 inches (133.00 mm).

This jobber drill is suited for production and maintenance drilling operations where tool life and hole accuracy are critical. The straight cylindrical shank fits standard drill chucks and collet systems. The 5xD flute-by-diameter ratio and 3.2677-inch flute length (83.00 mm) support drilling up to a maximum depth of 2.4803 inches (63.00 mm). Applications include structural steel fabrication, stainless steel component machining, and general metalworking in job shops, maintenance facilities, and production environments. Its tapered web configuration and high-performance carbide grade make it a reliable choice where tool consistency matters across multiple holes.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• Multilayer TiAlN coating for extended tool life under elevated cutting temperatures
• 140-degree point angle reduces thrust and centers quickly on flat or curved surfaces
• Coolant-through design delivers cutting fluid directly to the cutting edge for deep-hole drilling
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Regular spiral 2-flute geometry promotes efficient chip removal and reduced recutting

Compatibility

Compatible with standard drill chucks and collet toolholding systems that accept a 0.4219-inch straight cylindrical shank. Designed for use on CNC machining centers, drill presses, and manual or CNC lathes performing drilling operations in steel, stainless steel, cast iron, aluminum, and non-ferrous materials.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle and toolholder are clean and free of chips before seating the shank. Verify coolant-through lines are connected and flowing before engaging the cut when using internal coolant. Inspect the cutting edges and point geometry before use and replace the drill if chipping or coating breakdown is observed.
