A local contract manufacturer.
The customer was tapping a "blind hole" in 17-4PH stainless steel and felt they were not getting apporiate productivity and tool life. They were using a high speed steel "OSG" 10-32 2B tap with an oxide coated surface.
H&C Tool Supply recommended they test a Kennametal tap with a chromium carbide carbon (CRCC) coating. Kennametal technicians came to thier facility and ran a test.
The customer was very pleased with the results of the test:
The cost of the "OSG" tap was $15.86 per tap.
The Kennametal tap cost was $36.92 per tap.
The increased production and increased tool life, more than offset initial tooling cost.
H&C Tool Supply would be more than happy to help you reduce your costs as well!
