Kennametal 4150667 Solid Carbide Jobber Drill 5.00 Mm

Product Description

The KENNAMETAL 4150667 is a solid carbide jobber-length drill bit designed for high-performance hole-making in ferrous and non-ferrous materials. It features a 140-degree split point angle for accurate self-centering and reduced thrust force on entry. The multilayer TiAlN coating provides heat resistance and extended tool life in demanding cutting conditions. The 5.00 mm diameter (0.1969 inch decimal equivalent) bit runs a right-hand spiral flute geometry with a whistle notch shank for secure chuck retention. Licensed machinists, tool-and-die technicians, and maintenance professionals specify this bit for precision drilling work.

This drill bit is suited for production and job-shop applications where consistent hole quality in steel, stainless steel, cast iron, and aluminum or other non-ferrous materials is required. The 44.00 mm flute length provides adequate chip evacuation in moderate-depth holes, and the 82.00 mm overall length fits standard drill chucks and CNC toolholders. It is rated as a high-performance grade, making it appropriate for both manual machine operation and CNC drilling cycles where rigidity and accurate spindle runout are maintained.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Multilayer TiAlN coating for elevated heat resistance and longer cutting life
• 140-degree point angle promotes self-centering and reduces walking on entry
• Right-hand spiral flute geometry supports efficient chip evacuation
• Whistle notch shank ensures positive chuck engagement and prevents slipping under torque
• High-performance grade rated for steel, stainless steel, cast iron, and aluminum alloys

Compatibility

Designed as a high-performance replacement jobber drill for applications requiring a 5.00 mm solid carbide bit with a whistle notch shank, suitable for use in standard drill chucks and CNC toolholding systems that accept this shank style.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with cutting tool practices. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or toolholder. Verify chuck or collet capacity and runout before starting a drilling cycle, as excessive runout accelerates carbide wear and increases the risk of breakage. Follow applicable shop safety standards and machine manufacturer guidelines for speeds, feeds, and coolant application.
