Kennametal 4150718 Solid Carbide Jobber Drill 8.50 Mm

Product Description

The KENNAMETAL 4150718 is a solid carbide jobber-length drill designed for high-performance hole-making in ferrous and non-ferrous materials. It features an 8.50 mm cutting diameter, a 140-degree split point, and a multilayer TiAlN coating that extends tool life under demanding cutting conditions. The overall length is 103.00 mm (4.0551 inches), with a flute length of 61.00 mm (2.4016 inches) and a straight cylindrical shank. Right-hand spiral flutes provide efficient chip evacuation. This drill is intended for use by machinists, toolroom professionals, and maintenance technicians working on production or precision drilling operations.

The 4150718 is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous workpiece materials. Its 5xD flute-to-diameter ratio and tapered web configuration support stable entry and consistent hole quality in both through-hole and blind-hole applications. Typical installation scenarios include CNC machining centers, drill presses, and hand-held power tools where a straight-shank drill is required. The 140-degree point angle reduces thrust force and improves self-centering, making it well suited for interrupted cuts and harder alloys.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-performance drilling
• Multilayer TiAlN coating improves heat resistance and extends tool life
• 140-degree point angle reduces entry thrust and improves self-centering
• Right-hand regular spiral flutes promote efficient chip evacuation
• Tapered web configuration adds strength at the drill tip
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-fit jobber drill for use in any machine tool spindle or chuck accepting a 10 mm straight cylindrical shank. Compatible with primary workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys per manufacturer specification.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety practices. Secure the straight shank firmly in a collet, drill chuck, or tool holder rated for the shank diameter before operation. Inspect the cutting edges and coating for damage before each use and replace the tool if chipping or excessive wear is observed. Follow all applicable machine guarding and PPE requirements per OSHA and shop safety standards.
