Kennametal 3794922 Ksem Plus Pilot Insert Drill Head

Product Description

The KENNAMETAL 3794922 is a KSEM Plus series pilot insert drill head engineered for high-performance indexable drilling applications. It accepts an FDS40 head connection and supports a maximum drill diameter of 41.28mm (1.6252 inches). The head carries a fixed 18mm (0.7087 inch) pilot insert and accommodates two nonpilot inserts secured by screw-holding method. At 25mm (0.9843 inches) in head length and 28.80mm (1.1339 inches) from head to pilot tip, this drill head is built for precision boring in metalworking environments. Coolant-through capability supports chip evacuation and tool life in demanding cuts. Installation includes an insert screw and wrench.

The 3794922 is suited for CNC machining centers and heavy-duty drilling operations in ferrous and nonferrous metals. The KSEM Plus platform is a modular indexable drill system designed for production environments where repeatability and insert changeability reduce downtime. This drill head targets machinists and tooling technicians running high-volume hole-making operations in manufacturing, aerospace, oil and gas, and general metalworking shops. It is intended for use with compatible KSEM Plus shanks and bodies accepting the FDS40 interface.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable modular drill systems. Disengage machine power and confirm spindle is fully stopped before changing the drill head or inserts. Use only the supplied insert screw and wrench to seat inserts to the manufacturer-specified method. Verify FDS40 interface is clean and free of debris before torquing the head connection to prevent runout.
