Cermet II Saw Tips

Saw tips that work 2, 4, 5 and 10 times as well as carbide

They braze and grind like carbide. 

Three Advanced materials

Cermet II – proven cermet grades that always work.  These are grades that have worked well in field tests for a year or more.  They have never worked worse than carbide and about 95% of those who try them are now ordering them in thousands at a time.   About twice the price of carbide and worth it as they can give results five to ten times as good. 

Cermets – experimental grades of various chemistries that sometimes work and sometimes don’t.  Sometimes are much better than carbide and sometimes much worse.   

Ceramics – experimental - should work well in brazed applications as they do in mechanically held applications but they haven’t worked yet. 

Refer back to the Tool Material Index for more information on other tooling Materials.  

Cermet II Grades Cut Faster and Stay Sharper Longer Than C-4 Carbide. 

Benefits You Get

Ø      Grinds like regular carbide

Ø      Gives a better edge than carbide grades.

Ø      Stays sharper longer than carbide grades

Ø      Substantial increase in fracture toughness.

Ø      More corrosion-resistant

Ø      Better at high temperatures achieved when cutting and drilling.

Ø      Cuts faster

Ø      Cuts faster and longer while being tougher.  Longer runs and less downtime.

Time of Cut Data

This was done with a mechanically controlled constant push on the chop saw.  We ran different saw blades with different tooth counts in different materials.  The test was run until some of the saw dulled out.

Successful Cermet II Applications

We called customers who had ordered and re-ordered and this is what they told us they were doing.   The applications and the testimonials to success don’t mean nearly as much as the fact that they keep reordering.  

Ø      Trimming to size at plywood plant, any custom blade he makes, Rip saws cutting , Pine and Fir, Panel saws cutting Melamine

Ø      running / making panel saws  for tooling industry for shelving furniture and Laminated particleboard. He was using  C-4 grade now and was looking for abrasion resistance. 

Ø      noticed improvements and keeps reordering for a customer of his who makes blades.

Ø      Just got the blades back and they are lasting longer in Oak and Aspen.

Ø      Tips went longer without sharpening.

Ø      Cutting rail road ties

Ø      Metal and  all secondary   applications

Ø      Formica coated board, double sided fiber board and particleboard for cabinetry

Ø      All cutting

Ø      Pecan  - working well blades came back sharper than usual with C3

Ø      Finger joint plant very fast cuts in very dry wood. Used to have cracked carbide, but nail cutting grade solved the problem.
