Overview

The EDM-8C is an 800 watt, 110V portable electrical discharge machine built to burn out a broken tap, drill bit, or bolt from a workpiece without cutting into the surrounding threads. It covers a stated removal range of 5/64 inch up to 25/32 inch and includes a depth setting meant for blind holes.

This class of machine trades a drill press and an easy-out for spark erosion: the electrode erodes only the broken steel, leaving the aluminum or hardened housing around it untouched. That matters most on tooling and dies where a snapped tap in a blind hole would otherwise mean scrapping the part.

  • 800W, 110V portable EDM
  • Removes taps 5/64 to 25/32 inch
  • Depth setting for blind holes
  • Also rated for drills, reamers and bolts

Who it's for

Machine shops, tool and die makers, and mold shops that periodically snap a tap or drill bit in a part too expensive to scrap. It suits benchtop use next to a mill or drill press rather than fieldwork.

Pros and cons

Pros
  • Covers a wide small-diameter range, 5/64 to 25/32 inch
  • Depth stop aimed at blind-hole work
  • 800W is enough for typical broken taps and small bolts
  • Compact 110V unit runs off a standard outlet
Cons
  • Rated 1.7 out of 5 by past buyers, with no review text on file to say why
  • No product description or spec sheet included in this listing
  • Manual feed, not automated

Performance notes

Like other tap burners, it works by lowering an electrode onto the broken fastener while the joint stays flooded with dielectric fluid. Rapid electrical discharges erode the metal in small bits rather than cutting it, so the process does not touch the surrounding threads or bore. The depth setting is meant to let the electrode stop short in a blind hole instead of punching through the far side.
