Kennametal 4150676 Solid Carbide Jobber Drill 7/32 Inch

Product Description

The KENNAMETAL 4150676 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding metal-cutting applications. It measures 7/32 inch (0.2188 inch decimal) in diameter and features a 140-degree split point for accurate self-centering and reduced thrust. The multilayer TiAlN coating provides heat and wear resistance during high-speed operations. With a right-hand spiral flute and whistle notch shank, this drill is built for use in CNC machining centers and production drilling environments where tool life and hole quality are priorities. Machinists and tool-and-die professionals are the typical end users.

This jobber drill is suited for production and maintenance drilling in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 140-degree point geometry performs well in interrupted cuts and on curved or angled entry surfaces common in fabrication and machining workflows. It is not designed for coolant-through applications. The whistle notch shank provides positive drive retention in standard drill chucks and collet holders compatible with that shank geometry.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 140-degree point angle reduces walking and improves hole entry accuracy
• Multilayer TiAlN coating extends tool life in high-temperature cutting conditions
• Right-hand spiral flute promotes efficient chip evacuation
• Whistle notch shank provides secure, positive drive in compatible holders
• High-performance grade suitable for production drilling cycles

Compatibility

Designed as a high-performance replacement jobber drill for use in CNC machining centers, drill presses, and production fixtures accepting a whistle notch shank in the 0.2000 to 0.2500 inch diameter range.

Installation Notes

Installation and replacement should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet compatibility with the whistle notch shank profile before seating the drill. Inspect the cutting edges and coating condition before each use to confirm the drill is fit for service.
