Kennametal 4150695 Solid Carbide Jobber Drill 17/64 in

Product Description

The KENNAMETAL 4150695 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding production environments. It measures 17/64 inch (0.2656 inch) in diameter and features a 140-degree split point geometry that reduces walking and improves entry accuracy without a center punch. The multilayer TiAlN coating extends tool life by increasing surface hardness and heat resistance at elevated cutting speeds. The whistle notch shank provides positive retention in standard drill chucks and tool holders. This bit is suited for machinists, tool-and-die shops, and production line technicians working with tight tolerances.

This drill bit is intended for use in ferrous and non-ferrous machining applications. Primary workpiece materials include steel, stainless steel, cast iron, aluminum, and other non-ferrous alloys. The right-hand spiral flute geometry promotes efficient chip evacuation during through-hole and blind-hole drilling operations. It is well suited for CNC machining centers, drill presses, and manual knee mills where consistent hole quality and tool longevity are priorities. The 17/64 inch diameter falls within the 0.2500 to 0.3000 inch drill bit size range, making it a common fit for fastener clearance holes and precision bores in light manufacturing and job-shop settings.

Key Features

• Solid carbide construction for superior rigidity and wear resistance compared to HSS alternatives
• Multilayer TiAlN coating for extended tool life at high cutting speeds and temperatures
• 140-degree point angle reduces thrust force and improves hole entry on hardened and tough materials
• Right-hand regular spiral flute for reliable chip evacuation in ferrous and non-ferrous workpieces
• Whistle notch shank for secure, slip-resistant retention in compatible holders
• High-performance grade suitable for production drilling at elevated feed and speed parameters

Compatibility

Designed as a high-performance OEM-style solid carbide jobber drill for use in CNC and manual machining setups that accept whistle notch shank tooling in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and all stored energy released. Confirm that the chuck or tool holder is rated for the shank diameter and style before seating the drill. Solid carbide tooling is brittle and should not be used in setups with excessive runout or lateral load. Inspect the cutting edges and coating condition before each use and replace the drill at the first sign of chipping or excessive wear.
