MODIFICATIONS OF STANDARD TOOLS
LOW COST AND PROMPT DELIVERY
Over 20% of standard tools ordered
specify one or more modifications
WHY MODIFY A STANDARD TOOL?
  • Modification of cutting form often eliminates subsequent machining operations
  • Modifications often improve cutting geometries for machining extra tough or abrasive materials
  • Shank modifications often improve tool holding or driving
  • Very short lead times - usually within one week, sometimes same day
  • Very economical for small quantities - often used to try new application ideas before committing to a large quantity, special tool order with longer delivery
