Kennametal 1913476 Screw Machine Drill Bit 5 Mm Tialn

Product Description

The KENNAMETAL 1913476 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537K specification, this bit features a 5.00 mm cutting diameter, a 140-degree split point for accurate self-centering entry, and a TiAlN coating that extends tool life under heat and abrasion. The web-thinned, parallel web geometry reduces thrust forces at entry. With an overall length of 66.00 mm and a flute length of 28.00 mm, it fits standard toolholding in CNC lathes, drill presses, and screw machine setups. Licensed tradespeople and machinists working production runs will find the geometry and coating well-suited for uninterrupted cycle times.

This drill bit is intended for use in steel, cast iron, aluminum, and non-ferrous materials. The screw machine length format makes it well-suited for close-tolerance drilling in short-reach toolholding systems common in production turning centers and automatic screw machines. The straight cylindrical shank diameter of 6.00 mm fits standard collet and chuck systems. Maximum drilling depth is 20.00 mm, keeping it aligned with stub-length, high-rigidity applications where hole straightness and finish quality are critical.

Key Features

• Solid carbide construction for rigidity and extended wear resistance in abrasive materials
• TiAlN coating improves heat resistance and tool life in ferrous and non-ferrous cutting
• 140-degree point angle with web thinning reduces entry thrust and improves self-centering
• DIN 6537K specification with DIN 6535 shank compliance for standardized toolholding fit
• Regular spiral, 2-flute geometry promotes efficient chip evacuation in through-hole drilling
• Flute-to-diameter ratio of 3xD supports balanced chip flow without excessive overhang

Compatibility

Designed for use in steel, cast iron, aluminum, and non-ferrous workpiece materials. Fits standard collet chucks and drill chucks accepting a 6.00 mm straight shank per DIN 6535. Suited for screw machine length toolholding configurations in CNC turning and drilling equipment.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and powered down before loading or changing tooling. Confirm shank seating depth and runout with a dial indicator before production use. Solid carbide tooling is brittle and should not be used in setups with excessive vibration or unsupported workpiece conditions.
