Kennametal 4149218 Solid Carbide Jobber Drill 5.50mm

Product Description

The KENNAMETAL 4149218 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding materials. It features a 5.50 mm diameter, a 140-degree point angle for aggressive entry and reduced thrust, and a multilayer TiAlN coating that extends tool life under heat. The two-flute spiral design promotes chip evacuation, and the tapered web configuration adds rigidity at the cutting tip. At 82.00 mm overall length with a 44.00 mm flute length, this drill fits standard jobber applications across machining centers and drill presses. Coolant-through capability makes it suitable for deeper cuts where heat buildup is a concern.

This drill is suited for machining steel, stainless steel, cast iron, and aluminum and non-ferrous materials. It conforms to DIN 6537K specifications, making it a fit for shops that standardize on metric DIN tooling. The straight cylindrical shank with a 6 mm diameter seats in standard collet chucks and drill chucks without additional adapters. Typical applications include production drilling in CNC machining centers, manual knee mills, and drill presses where consistent hole quality and tight diameter tolerances are required. The drill bit diameter tolerance of -0.0005 to 0.0000 inches supports close-tolerance work.

Key Features

• 5.50 mm diameter with -0.0005 to 0.0000 inch diameter tolerance for close-tolerance hole making
• 140-degree point angle reduces thrust and improves centering on entry
• Multilayer TiAlN coating increases heat resistance and tool life in ferrous materials
• Coolant-through design supports maximum drilling depth of 35.00 mm (1.3780 inches)
• DIN 6537K specification ensures dimensional conformance to metric tooling standards
• Tapered web construction adds core strength and rigidity during drilling

Compatibility

Rated for use in steel, stainless steel, cast iron, and aluminum and non-ferrous workpiece materials. Conforms to DIN 6537K specification for jobber-length solid carbide drills with straight shanks in the 5.00 mm to 6.00 mm diameter range.

Installation Notes

Installation is performed by qualified machinists or tool-and-die professionals. Before tool changes, power down the spindle and confirm the machine is in a safe state per shop lockout-tagout procedures. Seat the straight shank fully and evenly in the collet or drill chuck, and verify runout before beginning the cut. Solid carbide tooling is brittle - avoid lateral loading or interrupted cuts that could cause tip fracture.
