Kennametal 4149168 No.32 Solid Carbide Jobber Drill 140deg

Product Description

The KENNAMETAL 4149168 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. Built to DIN 6537K standards, it features a 140-degree split point, a multilayer TiAlN coating for heat and wear resistance, and an internal coolant-through channel that delivers cutting fluid directly to the cutting edge. The No. 32 wire gauge diameter measures 0.116 inches. The overall length is 2.284 inches (58 mm), with a 2-flute regular spiral configuration optimized for chip evacuation. This drill is intended for use by machinists, tool-and-die professionals, and CNC operators working in production environments.

This drill bit is suited for precision drilling applications in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The straight cylindrical shank diameter of 0.1575 inches fits standard drill chucks and collet systems. The 5xD flute-to-diameter ratio and 22 mm flute length support consistent chip clearance in short to medium-depth holes. It is well suited for CNC machining centers and drill presses operating at controlled feed and speed parameters where surface finish and hole tolerance are critical. The right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• DIN 6537K specification, solid carbide construction for rigidity and long tool life
• 140-degree point angle reduces thrust force and improves self-centering on entry
• Multilayer TiAlN coating resists heat and abrasive wear in ferrous and non-ferrous materials
• Internal coolant-through design delivers coolant directly to the cutting zone
• Regular spiral fluting promotes efficient chip evacuation in short to medium-depth holes
• Tapered web configuration adds strength at the core while maintaining cutting efficiency

Compatibility

Compatible with standard drill chucks and collet holders accepting a 0.1575-inch straight cylindrical shank. Designed for use in steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials per DIN 6537K specification.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC operator. Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable limits for the application. Engage the coolant-through system before the drill contacts the workpiece to prevent thermal shock to the carbide. Carbide tooling is brittle — avoid lateral loading, interrupted cuts without appropriate feed reduction, or dropping the tool on hard surfaces.
