Kennametal 2238532 Replaceable-tip Drill 16.66-17.16mm

Product Description

The KENNAMETAL 2238532 is a replaceable-tip drill body designed for precision hole-making in metalworking and machining applications. It accepts KSEM0656 series inserts at insert seat size 1, allowing the drill tip to be swapped without replacing the entire body. The tool features through-coolant capability via a 3.50 mm coolant hole, supporting chip evacuation and heat management during deep drilling. With a straight-cylindrical shank measuring 19.05 mm in diameter and an overall length of 4.75 inches, this drill body is sized for use in CNC machining centers and turning centers equipped with standard toolholding systems. Machinists and toolroom professionals install and service this type of tooling.

This drill body is suited for production drilling in ferrous and non-ferrous metals where hole diameter tolerance and depth consistency are critical. The replaceable-tip design eliminates the cost and lead time of regrinding, making it well suited for high-volume operations and job shops. It drills to a maximum depth of 50.01 mm at a 3xD depth-to-diameter ratio, targeting hole diameters in the 16.66 to 17.16 mm range. The tool belongs to the KSEM series product family, which is a modular drill system built around interchangeable cutting inserts and standardized seat sizes.

Installation Notes

Installation and tool changes should be performed by qualified machinists following the machine tool manufacturer and toolholder specifications. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the drill body or changing the replaceable tip insert. Confirm the shank is clean and free of burrs before seating in the toolholder, and torque the clamping mechanism per the toolholder manufacturer specification. Verify coolant supply lines are clear and delivering adequate flow before initiating a drilling cycle.
