Kennametal 1998947 Screw Machine Drill Bit 9.60 Mm

Product Description

The KENNAMETAL 1998947 is a screw machine length solid carbide drill bit engineered for high-performance drilling in demanding industrial applications. Built to DIN 6537K specification, this bit features a 140-degree split point geometry with web thinning, which reduces thrust forces and improves chip evacuation at entry. The TiAlN coating extends tool life in abrasive and high-temperature cutting environments. With a 9.60 mm cutting diameter and an overall length of 89.00 mm, this is a compact, rigid drill designed to deliver precise, repeatable holes. It is typically installed and operated by machinists and tool-room professionals using CNC machining centers, drill presses, or turret lathes.

This drill bit is suited for production drilling in cast iron and steel workpieces where dimensional accuracy and tool longevity are priorities. The straight cylindrical shank fits standard ER collets, drill chucks, and hydraulic toolholders commonly found in machine shop environments. Its screw machine length profile provides added rigidity compared to jobber-length drills, making it well-suited for short-hole applications, fixture drilling, and high-volume production runs. The KENNAMETAL B966A series and Dynapoint High Performance grade classification indicate this bit is positioned for demanding duty cycles.

Key Features

• Solid carbide construction in material grade KC7315 for rigidity and wear resistance
• TiAlN coating for extended tool life in ferrous and abrasive materials
• 140-degree split point with web thinning reduces entry thrust and improves centering
• Screw machine length for added stiffness in short-hole drilling operations
• Right-hand, regular spiral flute geometry promotes efficient chip clearance
• Meets DIN 6537K specification for dimensional consistency

Compatibility

Designed for use in cast iron and steel workpieces. Compatible with standard straight-shank toolholders, ER collet chucks, and drill chucks accepting a 10.00 mm shank diameter. Suitable for CNC machining centers and manual machine tools with appropriate spindle speeds and feeds for solid carbide tooling.

Installation Notes

Solid carbide drill bits must be handled carefully to avoid chipping — do not drop or contact other hard tooling. Ensure the toolholder is clean and properly torqued before operation, and confirm spindle runout is within acceptable limits for the diameter being drilled. Always reference the manufacturer's recommended speeds and feeds for the specific workpiece material and machine setup. Power down and lock out the machine before changing tooling.
