The KENNAMETAL 4150678 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. It features a multilayer TiAlN coating that resists heat and extends tool life in interrupted cuts and continuous drilling operations. The right-hand spiral flute geometry promotes efficient chip evacuation, and the whistle notch shank provides positive retention in standard drill chucks and collet holders. This drill is suited for production environments where tool longevity and dimensional accuracy are priorities across a range of workpiece materials.
This jobber drill is intended for use on steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. It fits machining centers, CNC drilling stations, and manual drill presses where a standard jobber-length reach is appropriate. The solid carbide construction makes it well suited for higher spindle speeds and harder workpiece materials compared to high-speed steel alternatives. Machinists and toolroom technicians working in job shops, production facilities, and maintenance departments will find this drill applicable across a wide range of drilling applications.
Designed as an OEM-style jobber drill compatible with standard drill chucks and collet holders that accept a whistle notch shank. Suitable for use on steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials as specified by the manufacturer.
Installation and tool changes should be performed by a qualified machinist with the machine powered down and locked out per applicable safety procedures. Ensure the whistle notch shank is fully seated and the retention fastener is torqued per the toolholder manufacturer specifications before operation. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life. Inspect the cutting edges for chipping or wear before each use, as carbide is brittle and prone to edge damage if mishandled.
