Slotting Mills
When it comes to slot milling, the rigidity of the cutter is a very important factor to consider when removing material from the workpiece. The right slotting tool will maintain accuracy and toughness while controlling inevitable chatter. Kennametal slotting cutters and inserts have the improved durability needed to take full advantage of the long lifespan of every machining tool we manufacture. Our slot mill offering gives you access to a wide selection of insert geometries and grades for slotting or grooving most workpiece materials at a wide range of speeds and feeds. Ultimately, Kennametal slotting mills provide you with the maximum material removal rate you want without sacrificing quality or accuracy.
No matter how challenging your slot milling operation is, you’ll be able to boost productivity with our KNS, KVNS, KSSM, KTMS, KTMS slot cutters and inserts.
