Kennametal 4150204 Screw Machine Drill Bit Size 14 Carbide

Product Description

The KENNAMETAL 4150204 is a solid carbide screw machine length drill bit designed for precision hole-making in demanding metalworking applications. Built to DIN 6537K standards, this stub-length drill features a 140-degree point angle for improved centering and reduced thrust in hard or abrasive materials. The straight-cylindrical shank measures 0.236 inches in diameter, and the overall length is 2.598 inches, making it compact and well-suited for use in tight setups or CNC screw machine operations. The TiAlN multilayer coating at the tip extends tool life in ferrous and stainless materials. Licensed machinists and CNC operators will recognize this as a high-performance production drill for short-hole applications.

This drill bit is intended for use in screw machine operations, CNC machining centers, and manual drilling setups requiring a stub-length tool. It is sized at wire gauge number 14, which corresponds to a decimal diameter of 0.182 inches. The B041A-CPG series designation places it within a family of solid carbide stub drills optimized for high-speed production environments where hole location accuracy and surface finish are critical. It is appropriate for shops working with steel, cast iron, and similar materials where a TiAlN-coated carbide tool is specified.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree standard point angle for accurate self-centering and reduced walking
• TiAlN multilayer coating on tip extends cutting life in ferrous applications
• Stub screw machine length for reduced deflection and improved hole straightness
• Regular spiral flute geometry with tapered web for efficient chip evacuation
• Conforms to DIN 6537K specification for consistent dimensional accuracy

Compatibility

Designed as a DIN 6537K-compliant screw machine length drill bit suitable for use in standard straight-shank drill chucks and collet holders accepting a 0.236-inch shank diameter.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC technician. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the drill from the chuck or collet. Verify chuck or collet runout is within acceptable limits before use, as excessive runout will shorten tool life and reduce hole quality. Do not exceed the recommended maximum drilling depth of 0.669 inches for this stub-length tool.
