General Information


Rock River Tool sells through industrial distributors who are your local supply, service and communication link with us.


All shipments are normally sent UPS to the distributor. However, every day distributors request “next day delivery” or “drop shipments” to customers that must have the tools immediately.


The Rock River EDP number listed for each size of every tool type is the only description required when ordering. However, as a cross-check for possible copying errors, most orders also note a brief tool description.


Over 30% of the standard tools ordered include one or more simple modifications. Each product page lists the most commonly requested modifications for that type of tool. Rock River’s modifications are competitively priced with prompt delivery.

Quality Assurance

Rock River has a detailed written quality assurance program, including a very comprehensive measurement instrument dimensional control system. We apply statistical techniques wherever appropriate to assure manufacturing process control and effective final inspections.


All Rock River’s standard tools are manufactured to one or more of the following specifications:

  • ANSI B94.11M – American National
    Standards Industry
  • NAS 907 – National Aerospace Standards
  • USCTI – United States Cutting Institute
  • ISO – International Standard Organization

Carbide Grades

All Rock River’s standard tools are manufactured with correct proven grade of carbide for the intended applications. We only utilize carbide that is supplied by major reputable manufacturers.

Tool Performance

Although the tool’s price is always important, the real measure of tool value is the tool’s performance in the user’s plant — machining piece parts to correct dimensions with proper surface finishes utilizing high feeds and speeds with a long tool life between grinds.


All specifications and dimensions are subject to revision without notice.
