KENNA PERFECT Inserts – Cast Iron




 Tool Tips:
 Wiper Inserts
 Wiper inserts are an excellent choice for straight OD, ID, and facing cuts. Feed rates can be doubled,
 reducing machining time by 50% while maintaining the surface finish. Insert nose radius has no effect on
 finish since the wiper radius generates the final finish. Wiper inserts typically last longer since the work is
 spread over a longer cutting edge.



 Grade KC9315™
 Grade KC9315 is the first choice for machining ductile irons. The thick medium-temperature CVD
 TiCN layer combats flank wear, which is the usual failure mechanism when machining ductile irons
 with a tensile strength of 50 ksi and greater. Use geometries ..MA, MG-UN, and MG-RP.



 Grade KC9325™
 Grade KC9325 is ideally suited for machining gray irons and low-strength ductile irons (<45 ksi).
 Crater wear is the primary wear mechanism when machining gray irons at high speeds. Grade KC9325
 combats crater wear with a very thick Al2O3 layer. The grade’s unique combination of toughness and
 speed capability make it a first choice for gray iron machining up to 1300 sfm.



 MG-RP Geometry
 The -RP geometry is available in a wide variety of grades and can be used to reduce cutting forces on
 unstable cuts or where work holding is not optimal. This is particularly advantageous when machining
 high-strength ductile irons (≥ 80 ksi). Reduced forces lower the temperature at the cutting interface, pro-
 viding long, predictable tool life.



 Grade KC9110™
 Grade KC9110 is an excellent choice for interrupted cutting conditions where grades KC9315 and
 KC9325 are not tough enough. Its unique combination of speed capability and outstanding toughness
 makes it an excellent choice for heavily interrupted cuts. Use MG-RN geometry as a first choice.

KENNA PERFECT Inserts – Cast Iron




Tool Tips:
Grade KY3500™
Kyon 3500 is your first-choice ceramic cutting tool for tough gray cast iron applications, especially those
with interruptions and scale. KY3500 is the most dependable ceramic grade for harsh gray cast iron
applications, and can be run wet or dry.




Grade KY1310™ (available January 2004)
Kyon 1310 is designed specifically to maximize tool life in dry, continuous gray cast iron applications.
Although not as tough as KY3500, KY1310 possesses good toughness at a high hardness level to
optimize abrasive wear properties. Use KY1310 for continuous cutting in tandem with KY3500 for more
severe gray cast iron cutting applications to maximize tool life and minimize costs.



Top Notch® Turning System for Ceramics
When cutting with ceramics at high speeds, it is important to maximize the rigidity of the insert and
toolholder. The Top Notch tooling system used in tandem with grades KY3500, KY1310, and KY3400
“dimple” inserts provides ultimate rigidity for cast iron applications.



Insert Failure Analysis
Check the insert thoroughly for signs of failure. To optimize your metalcutting process, remove inserts
from the toolholder and inspect regularly for wear. Signs of chipping, deformation, built-up edge,
cratering, flank wear, and thermal cracking are very evident in the early stages of wear but are almost
impossible to detect after total insert failure.



Boring with Wiper Inserts
When boring with wiper inserts, chatter may increase due to the large wiper radii. To offset this lateral
tool pressure, decrease the nose radius and increase the depth of cut. Remember that the nose radius
of a wiper insert doesn’t affect surface finish.




                                                                                                              19

resistance to crater wear. An under layer of
medium-temperature titanium carbonitride provides
excellent resistance to flank wear. A tough,
deformation-resistant substrate is designed to
work together with this new coating to maximize
resistance to crater wear.
The application range of KC9325 is expanded
with improved performance in medium to heavy
machining of both ductile irons and steels. Grade
KC9325 also uses a mechanical post-treatment
process to condition the surface to resist micro-
chipping and chip hammering. The smooth alumina
top layer provides excellent resistance to build up
and enables the cut chip to flow quickly and easily
over the cutting edge for significantly longer tool life.

     latest in state-of-the-art turning technology. Our new -RW
     (Roughing Wiper), -MW (Medium Wiper) and -FW (Finishing
     Wiper) inserts employ a modified corner radius design that
     delivers a superior surface finish compared to conventional
     inserts. This technology allows you to choose the metalcutting
     benefit that’s most important to your application.

     Double Productivity
     Kennametal’s new wiper geometries allow you to double your
     current feed rate and still achieve surface finishes comparable
     to conventional inserts. You’ll also see equivalent or better tool
     life using the appropriate KENNA PERFECT grade specifically
     designed for your workpiece material.

     Better Workpiece Finish
     These new wiper geometries also will give you a markedly improved
     surface finish at your current machining conditions. Under typical
     conditions, you’ll see as much as
     a 250% improvement in the
     workpiece surface finish, all
     with inserts that meet your
     corner radius specifications.

     You choose! Either way,
     we’re sure you’ll agree that the
     new wiper geometries from
     Kennametal provide an
     outstanding way to optimize
     your turning operations.
     Please see the accompanying
     information for proper
     application guidelines.

advantages as negative style inserts. When

Nose radius and feed rate have the greatest impact
on surface finish. To determine the nose radius
required for a theoretical surface finish, use the
following procedure and the chart above.
1     Locate the required surface finish (rms or AA)
      on the vertical axis.
2     Follow the horizontal line corresponding to the
      desired theoretical finish to where it
      intersects the diagonal line corresponding
      to the intended feed rate.
3     Project a line downward to the nose radius
      scale and read the required nose radius.
                                                          NOTE: Peaks produced with a small radii insert (top) compared
4     If this line falls between two values, choose       to those produced with a large radius insert (bottom).
      the larger value.
    • If no available nose radius will produce the
      required finish, feed rate must be reduced.
    • Reverse the procedure to obtain surface
      finish from a given nose radius.
*NOTE: See pages 57-59 for radius and surface
       finish specifications using wiper-style inserts.
