Kennametal 4149167 Solid Carbide Jobber Drill 2.90mm

Product Description

The KENNAMETAL 4149167 is a solid carbide jobber-length drill designed for high-performance drilling in metalworking applications. It features a 2.90 mm (0.1142 inch) diameter, a 140-degree point angle, and a multilayer TiAlN coating for extended tool life under demanding cutting conditions. The drill has an overall length of 58.00 mm (2.28 inches) with a 22.00 mm (0.87 inch) flute length and a straight cylindrical shank measuring 4 mm (0.25 inch) in diameter. Two regular spiral flutes provide efficient chip evacuation, and coolant-through capability supports high-speed drilling cycles in production environments. It conforms to DIN 6537K specification.

This drill is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both shop and production settings. The 5xD flute-to-diameter ratio and tapered web configuration make it appropriate for CNC machining centers and drill presses where consistent hole quality and tight tolerances are required. It cuts in a right-hand direction and is packaged individually, making it a straightforward replacement or single-position tooling addition for machinists and tool-room technicians working within the 2.00 to 3.00 mm drill diameter range.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• Multilayer TiAlN coating supports elevated cutting temperatures and extends tool life
• 140-degree point angle reduces thrust force and improves self-centering on entry
• Coolant-through design delivers cutting fluid directly to the cutting edge during deep-hole drilling
• Conforms to DIN 6537K specification for dimensional consistency and interchangeability
• Tapered web configuration aids chip breaking and reduces walking on flat and curved surfaces

Compatibility

Designed as an OEM-style replacement or direct tooling solution for CNC machining centers, drill presses, and automated drilling stations requiring a 2.90 mm solid carbide jobber drill with a straight shank and coolant-through capability.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. The machine spindle must be brought to a complete stop and the tool-change interlock confirmed before inserting or removing the drill. The straight cylindrical shank requires a collet or drill chuck rated for the 4 mm (0.25 inch) shank diameter. Verify runout with a dial indicator after chucking to maintain hole-diameter tolerance within the stated range of -0.0006 to 0.0000 inches.
