Kennametal 1913462 Screw Machine Drill Bit 4.20 Mm Tialn

Product Description

The KENNAMETAL 1913462 is a solid carbide screw machine length drill bit engineered for precision drilling in steel, cast iron, and aluminum and non-ferrous materials. It features a 4.20 mm diameter, a 140-degree standard point angle, and a TiAlN coating that extends tool life in demanding production environments. The two-flute, regular spiral design provides efficient chip evacuation in short-depth drilling applications. The web-thinned geometry reduces thrust forces at entry, making it well suited for CNC machining centers, lathes with live tooling, and dedicated drill presses in metal fabrication shops. Installation and operation are typically handled by machining professionals and tool-room technicians.

This bit is designed for screw machine length applications where a compact overall length and rigid setup are required. It is well matched to high-volume production drilling operations in steel and cast iron components, as well as aluminum and non-ferrous workpieces. The straight cylindrical shank seats into standard collet chucks and drill chucks sized for a 6.00 mm shank. The Series B966A platform follows DIN 6535 and DIN 6537 dimensional standards, making it interchangeable with other tooling built to those specifications.

Key Features

• Solid carbide construction provides rigidity and wear resistance in metalworking applications
• TiAlN coating increases surface hardness and thermal resistance for extended tool life
• 140-degree point angle with web-thinned geometry reduces entry thrust and improves centering
• Regular spiral flute design with parallel web supports consistent chip flow in short-depth bores
• Straight cylindrical shank conforms to DIN 6535 for broad chuck compatibility
• Maximum drilling depth of 17.00 mm supports standard screw machine cycle depths

Compatibility

Designed as a DIN 6537K-compliant screw machine length drill bit for use in collet chucks and drill chucks accepting a 6.00 mm straight shank. Suitable for primary workpiece materials including steel, cast iron, and aluminum and non-ferrous alloys.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before seating or removing the bit from the chuck. Verify chuck or collet bore matches the 6.00 mm shank diameter before clamping to ensure runout is within acceptable limits. Do not exceed the rated maximum drilling depth of 17.00 mm per pass without confirming chip clearance and coolant strategy for the specific workpiece material.
