              Economical Drill-, Brad Point & Router Bit Grinder

The TDR/SRD family of drill grinders is exclusively U.S. designed and manufactured. Each offers a combination of speed, convenience, precision and versatility unmatched by machines many times their price. The "Cone Grinding Method" allows radial relief on all tools. The TDR's proprietary, self-dressing wheels operate dry, yet protect tools from burning. Web thinning is standard and requires no special attachments.

TDR/SRD grinders are simple to learn, simple to use, and simple to maintain. It's why we say they're simply the best.

  • Sharpens drills in less than 60 seconds.

  • Adjusts automatically between drill sizes.

  • Simple to learn - simple to operate.

  • Increases productivity.
