Kennametal 1913520 Screw Machine Drill Bit 5mm Carbide

Product Description

The KENNAMETAL 1913520 is a screw machine length drill bit engineered for high-performance drilling in ferrous materials. Built from solid carbide and coated with a multilayer TiAlN finish, it delivers extended tool life and heat resistance in demanding production environments. The 5.00 mm diameter bit features a 140-degree point angle with web thinning for reduced thrust and cleaner entry, and ships ready for coolant-through operation. Overall length is 66.00 mm (2.5984 inches), with a 6.00 mm straight cylindrical shank. Machinists and CNC operators working in job shops or production facilities will find this bit well-suited to high-cycle drilling applications.

This drill bit is designed for use in cast iron and steel workpieces, covering the primary material categories where solid carbide with TiAlN coating delivers the most consistent results. The screw machine length geometry keeps overhang short, improving rigidity and reducing deflection in close-tolerance work. Maximum drilling depth is 20.00 mm (0.7874 inches), and the regular spiral flute design promotes efficient chip evacuation. The Series B976 designation follows DIN 6537K specification, making it a standard-format tool compatible with collet chucks, drill chucks, and shrink-fit toolholders that accept a 6.00 mm shank.

Key Features

• Solid carbide construction with multilayer TiAlN coating for extended tool life in ferrous materials
• 140-degree point angle with web thinning reduces entry thrust and improves hole quality
• Coolant-through design supports high-speed production drilling and chip flushing
• Screw machine length (66.00 mm OAL) minimizes overhang for improved rigidity
• Regular spiral flute with parallel web configuration promotes consistent chip evacuation
• Conforms to DIN 6537K specification for standardized tooling compatibility

Compatibility

Designed for use in cast iron and steel workpieces. Accepts standard 6.00 mm straight shank toolholders including collet chucks, drill chucks, and shrink-fit holders. Diameter falls within the 5.00 to 6.50 mm size range of the B976 series.

Installation Notes

Installation and tool changes should be performed with the machine in a de-energized, locked-out state per applicable machine safety procedures. Verify the toolholder is clean and free of debris before seating the shank to the full 36.00 mm shank length. Coolant-through operation requires a compatible coolant-fed spindle or toolholder to realize full performance. Inspect the cutting edges before each use and replace at first signs of chipping or wear to avoid workpiece damage.
