Kennametal 4149126 Jobber Drill Size 31 Solid Carbide

Product Description

The KENNAMETAL 4149126 is a solid carbide jobber-length drill bit in wire gauge size 31 (0.1200 inches), designed for high-performance drilling in demanding metalworking applications. The 140-degree split point geometry promotes accurate self-centering and reduces thrust force at entry. A multilayer TiAlN coating improves heat and wear resistance, extending tool life in ferrous and non-ferrous materials. At 2.5984 inches overall length with a 1.1024-inch flute length, this drill suits compact setups and CNC machining centers. Coolant-through capability supports high-speed operation in difficult materials. Licensed machinists and CNC operators are the primary installers of this drill.

The 4149126 is intended for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous workpiece materials. Conforming to DIN 6537K, it fits applications where tight tolerances and repeatable hole quality are required. The straight cylindrical shank at 0.6250 inches (6 mm nominal) accepts standard drill chucks and collet holders. With a flute-by-diameter ratio of 5xD and a maximum drilling depth of 0.9055 inches (23.00 mm), it is well-suited to short-hole drilling cycles in production environments and job shop settings alike.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree point angle with standard point type for accurate entry and reduced walking
• Multilayer TiAlN coating extends tool life in high-heat cutting conditions
• Coolant-through design supports internal coolant delivery for chip evacuation and heat control
• Regular spiral flute geometry with tapered web configuration for efficient chip flow
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed as an OEM-style solid carbide jobber drill for use in standard drill chucks, collet holders, and CNC machining center spindles accepting a 0.6250-inch straight cylindrical shank. Compatible with workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys as stated by the manufacturer.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC technicians familiar with cutting tool setup. Ensure the machine spindle and tool holder are de-energized and fully stopped before inserting or removing the drill. Verify shank seating and runout with appropriate gauging before beginning a production run. Follow the machine tool manufacturer guidelines for feed rate, spindle speed, and coolant pressure when using coolant-through tooling.
