Precision Coolant Hole Machining for Cutting Tool Manufacturers

XACT Wire EDM Corporation has the capabilities and the expertise to handle the toughest high-speed small hole EDM drilling challenges. Our vast experience includes ed-boring holes in carbide and other hard-to-machine materials.

A common recent application for high-speed small hole EDM involves cutting tools. More and more shops are opting for machines with through-spindle coolant (TSC) which utilize cutters with coolant holes. This approach has many advantages over flood coolant: longer service life of the cutting tools, better finish on the workpiece, better chip evacuation, and increased productivity. Through-spindle coolant systems are also a must for operators monitoring multiple machines, and for lights-out manufacturing.

Depth to diameter ratios of 100/1 can be achieved in many cases (.040” diameter hole, 4.0” deep). Virtually no burrs are generated. No cutting forces are involved so no expensive fixturing is required to hold the cutter while drilling. Angle of entry and material hardness are not an issue since minute electrical discharges do the cutting.

We can also ed-bore holes with a machine which utilizes an oil-based coolant rather than the common deionized water. This process provides better edge control, surface finish, and machining speeds in carbide. It complements our numerous other high-speed small hole (HSSH) drilling machines that are used for all other conductive materials.

  • Electrode sizes from .010 (.25mm) to .118 (3.0mm) in a variety of configurations
  • Tolerances to +/-0.005” (and better if required)
  • Fast turnaround times
  • Test samples upon request
  • ISO 9001:2015 Certified
