Kennametal 4150334 Carbide Drill Bit 14mm 140 Deg

Product Description

The KENNAMETAL 4150334 is a screw machine length (stub-length) drill bit engineered for demanding metal-cutting applications. Built from solid carbide with a TiN tip coating, it delivers the rigidity and wear resistance required when drilling hard and abrasive materials. The 140-degree point angle reduces thrust force and improves chip formation on entry, while the regular spiral flutes evacuate chips efficiently. At 107.00 mm overall length (approximately 4.21 inches) with a 60.00 mm flute length (approximately 2.36 inches), this bit is designed for close-quarters drilling with minimal deflection. The 14.00 mm diameter straight-cylindrical shank seats securely in standard collet and drill press setups.

This drill bit is suited for production and job-shop environments where short, rigid tooling is preferred over jobber-length bits. The stub-length format reduces overhang and chatter, making it well-suited for CNC machining centers, drill presses, and screw machine operations running ferrous and non-ferrous materials. It carries a DIN 6537K specification designation, aligning with internationally recognized tooling standards. The Series B041A-CPG identifies this as a cataloged Kennametal carbide drill product. Right-hand cutting direction is standard for use with conventional spindle rotation. This tool is installed by machinists, toolroom technicians, and production setup personnel.

Key Features

• Solid carbide construction for high rigidity and extended tool life in hard materials
• TiN tip coating reduces friction and improves wear resistance at the cutting edge
• 140-degree split-style point angle lowers entry thrust and minimizes workpiece walkout
• Stub-length (screw machine) format minimizes deflection and supports tighter positional tolerances
• Straight-cylindrical shank compatible with standard collets and drill chucks
• DIN 6537K specification compliance for consistent dimensional standards

Compatibility

Designed as a DIN 6537K-compliant stub-length solid carbide drill for use in CNC machining centers, screw machines, and drill press applications requiring a 14.00 mm diameter right-hand cutting tool with a straight shank.

Installation Notes

This tool is installed and changed by qualified machinists or toolroom personnel. Before tool changes, ensure the spindle is fully stopped and the machine is locked out per facility LOTO procedures. Verify the collet or chuck is clean and undamaged before seating the shank, and confirm runout with a dial indicator when positional accuracy is critical. Do not exceed the maximum recommended drilling depth of 43.00 mm (approximately 1.69 inches) per the tooling specifications.
