Kennametal 4149657 Taper Length Drill Bit

Product Description

The KENNAMETAL 4149657 is a taper length drill bit designed for precision hole-making in metal fabrication, mechanical assembly, and industrial maintenance applications. Taper length drill bits offer a longer flute and body than jobber-length bits, providing added reach and chip clearance in deeper drilling operations. Weighing 0.7 pounds, this bit is suited for use with standard drill presses, magnetic drills, and CNC machining centers. It is typically installed and operated by machinists, millwrights, and maintenance technicians working in industrial or trade environments where accurate, clean-bore drilling is required.

This taper length drill bit is intended for industrial drilling operations where standard jobber-length bits fall short in reach or rigidity. It is well suited for metal working applications including structural steel fabrication, equipment maintenance, and precision part manufacturing. The extended length design allows access to deeper hole locations without sacrificing drill stability. Sold individually, this bit is appropriate for both production environments and single-use maintenance tasks.

Key Features

• Taper length design provides extended reach beyond standard jobber-length drill bits
• Longer flute geometry promotes improved chip evacuation in deeper holes
• Suitable for use with drill presses, CNC machining centers, and magnetic drills
• Sold as a single unit for flexible purchasing
• Lightweight construction at 0.7 pounds for easy handling and tool changes

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit for industrial drilling applications in standard drill chucks and collet systems accepting the applicable shank size.

Installation Notes

Taper length drill bits are installed and operated by qualified machinists or maintenance technicians. Ensure the drill press or machining center is fully powered down and locked out before changing bits. Secure the bit firmly in the chuck or collet to the manufacturer-specified engagement depth before operation. Use appropriate cutting fluid for the material being drilled to extend bit life and maintain hole quality.
