Kennametal 1995000 Screw Machine Drill Bit 5.10mm Carbide

Product Description

The KENNAMETAL 1995000 is a solid carbide screw machine length drill bit designed for high-productivity drilling in cast iron and steel. It features a 5.10 mm diameter, a 140-degree split point for self-centering starts, and a multilayer TiAlN coating that extends tool life under heat and abrasion. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders. At 66.00 mm overall length, this short-series bit delivers the rigidity needed for accurate, chatter-free holes in CNC machining centers, drill presses, and screw machine applications. Installation and use are handled by machinists and tool-room technicians working in production or job-shop environments.

This drill bit is suited for drilling cast iron and steel workpieces in both production machining and maintenance operations. The screw machine length geometry provides extra stiffness compared to jobber-length bits, making it a reliable choice for tight-tolerance bores and high-cycle applications where runout and deflection must be minimized. It conforms to DIN 6537K specification, which governs short solid carbide drills used widely in European and North American precision machining standards.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Multilayer TiAlN coating for extended tool life at elevated cutting temperatures
• 140-degree point angle with web thinning reduces thrust force and improves centering
• Screw machine length design provides superior stiffness over jobber-length alternatives
• Right-hand, regular spiral flute promotes efficient chip evacuation
• Conforms to DIN 6537K specification for consistent dimensional standards

Compatibility

Designed for use in cast iron and steel workpieces. The 6.00 mm straight-cylindrical shank is compatible with standard ER collets, drill chucks, and hydraulic toolholders sized for that shank diameter. Part of the Kennametal Series B966 solid carbide drill line.

Installation Notes

This bit is installed by machinists or tool-room personnel in CNC machining centers, drill presses, or screw machines. Ensure the machine spindle and toolholder are clean and free of debris before seating the shank. Always confirm spindle speed and feed rate against the manufacturer cutting data for the specific workpiece material before operation. Do not exceed the maximum drilling depth of 20.00 mm without retracting to clear chips.
