Kennametal 4149668 Taper Length Drill Bit

Product Description

The KENNAMETAL 4149668 is a taper length drill bit designed for precision hole-making in metalworking and industrial machining applications. Taper length drills offer a longer flute and overall length than jobber drills, providing greater reach and improved chip evacuation in deeper drilling operations. This bit is sold as a single unit and is suited for use in drill presses, CNC machining centers, and manual machine tools where extended reach is required. Machinists and tooling professionals working in metal fabrication, aerospace, and general manufacturing rely on taper length geometry for consistent, accurate results in production environments.

This drill bit is intended for industrial and commercial machining applications where standard jobber-length drills lack sufficient reach. It fits typical setups involving ferrous and non-ferrous metals and is appropriate for both production floor use and maintenance machining operations. The single-piece packaging makes it suitable for toolroom stock or direct job use without additional handling requirements.

Key Features

• Taper length geometry provides extended reach beyond standard jobber-length drills
• Designed for deep-hole drilling with improved chip clearance
• Compatible with drill presses, machining centers, and manual lathes
• Single-unit packaging supports toolroom and per-job procurement
• UNSPSC Code 23241600 classifies this as a cutting tool for industrial use

Compatibility

Designed as an OEM-style replacement or direct toolroom substitute for taper length drill bit applications in standard industrial drilling equipment accepting straight-shank or taper-shank drill bits of the applicable diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with machine tool operation. Ensure the spindle is fully stopped and the machine is de-energized before inserting or removing the drill bit from the chuck or taper socket. Verify that the shank is fully seated and the chuck or adapter is properly tightened before initiating a cut. Follow applicable workplace safety standards and machine manufacturer guidelines for speeds, feeds, and coolant use.
