Kennametal 1606888 Replaceable-tip Drill Ksem Series 5xd

Product Description

The KENNAMETAL 1606888 is a replaceable-tip drill body in the KSEM series, designed for precision hole-making in metalworking and machining applications. It accepts KSEM0922 insert tips at an Insert Seat Size 4, covering a drill diameter range of 23.42 to 23.92 mm (0.922 to 0.9417 inches). The body features a 25.4 mm straight-cylindrical shank and supports through-coolant delivery via a 3.50 mm coolant hole, helping to manage heat and chip evacuation at depth. The 5xD depth-to-diameter ratio allows drilling to a maximum depth of 119.89 mm (4.72 inches). This tool is intended for use by machinists and CNC operators on vertical machining centers, horizontal machining centers, and CNC turning centers.

The 1606888 drill body is suited for production environments requiring consistent, repeatable hole quality in a diameter range just under 24 mm. The replaceable-tip design reduces downtime by allowing insert changes without removing the body from the toolholder. Typical applications include structural part drilling in steel, cast iron, and similar machinable alloys. The through-coolant feature makes it particularly effective for deeper holes where chip packing and thermal buildup are concerns. Compatible insert style KSEM0922 is specified for this body.

Key Features

Compatibility

Designed for use with KSEM0922 replaceable drill tip inserts at Insert Seat Size 4. The 25.4 mm straight-cylindrical shank is compatible with standard toolholders accepting that shank diameter. No additional model-specific compatibility data was provided in the input.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and all energy is locked out before mounting or removing the tool body from the toolholder. Verify the insert seat is clean and free of chips before seating the KSEM0922 tip, and torque the clamping screw per the insert manufacturer torque specification found in the KSEM tooling documentation. Confirm through-coolant supply pressure and flow are consistent with the machine tool specifications before beginning the drilling cycle.
