Kennametal 2238566 Replaceable-tip Drill 30.16-30.66mm

Product Description

The KENNAMETAL 2238566 is a replaceable-tip drill body in the KSEM series, designed for high-productivity hole-making in metalworking and machining operations. The body accepts KSEM1188 inserts at insert seat size 8, covering a drill diameter range of 30.16 to 30.66 mm (1.1874 to 1.2071 inches). Maximum drill depth reaches 90.49 mm (3.56 inches), representing a 3xD depth-to-diameter ratio. The straight-cylindrical shank measures 31.75 mm in diameter and 82.55 mm in length. Through-coolant capability is built in, with coolant holes at 5.00 mm diameter, supporting chip evacuation and tool-life management in production environments. Machinists and CNC operators working in job shops, aerospace, automotive, and general manufacturing will find this body well suited to their turning-center and machining-center setups.

The 2238566 drill body is intended for use in CNC machining centers and turning centers where consistent, repeatable hole quality at larger diameters is required. The replaceable-tip design allows the cutting insert to be swapped without removing the body from the spindle, reducing downtime on production runs. The 3xD depth ratio suits through-holes and blind holes in steel, cast iron, and similar workpiece materials common in general metalworking. The overall length of 8.13 inches and a flute length of 4.72 inches accommodate typical toolholder setups with this shank diameter class.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before mounting or removing the drill body, the machine spindle must be fully stopped and the control placed in a safe state per shop lockout-tagout procedures. The straight-cylindrical shank should be secured in an appropriately sized toolholder with adequate clamping torque per the toolholder manufacturer's specification. Verify coolant line connections are clear and delivering adequate flow before initiating a drilling cycle to protect the insert and workpiece.
