Monaghan Tooling Group (Dayton, OH) presents the innovative Diatool Top Speed Ring (TSR) modular reaming system which achieves up to 70% faster feed rates with “out-of-the-box” functionality. Specifically:

  • With up to four additional cutting blades, this unique design allows not only faster machining but also increased tool life, to achieve unrivaled performance and cost-efficiency. 
  • The multi-blade design features uneven spacing of cutting edges, to create exceptionally round and cylindrical bores. 
  • The TSR comes set to size and requires no additional setup, delivering ready-to-cut functionality. 
  • Moreover, the holders are equipped with internal coolant as a standard feature. 
  • A video demonstration showing the ease of assembly is available at

In addition to long service life, the Diatool TSR has an economical design, with rings that can be reconditioned countless times to original equipment manufacturer (OEM) specifications, achieving the same tool life as a new reamer. This exceptional reusability makes the Top Speed Ring both efficient and cost-effective., 800-732-4565
