The “Metlor” designed and developed armed wheel type strain gauge based Drill Tool Dynamometer designed to measure Thrust & Torque during drilling operation and effect of speed, feed cut on these forces. The unit consists of a mechanical sensing unit or test piece holder and digital force indicator. The job can be mounted on a workplace holder on mechanical sensing unit. The unit is useful for drilling up to 20 mm dia.

A machine-tool dynamometer is a multi-component dynamometer that is used to measure forces during the use of the machine tool. Empirical calculations of these forces can be crosschecked and verified experimentally using these machine tool dynamometers.


  • Rigid in construction & Sensitive transuding and amplifying system for accuracy in force measurement.
  • Compact two-channel digital force indicator.
  • Use of cutting fluid during operation is possible


  • Mechanical Sensing Unit with Job Holder with strain Gauges mounted on it.
  • Control panel housing digital force indicator to measure both forces simultaneously, balancing potentiometer, connoting cables.
  • Digital Force Indicator – two channel, to read both thrust and torque simultaneously.
  • Balancing Potentiometer for initial balancing
  • Range – thrust – 0 to 200 Kg, torque – 0 to 20.0 Kg m, least count – 0.1 Kg m.
  • The set up is calibrated at our works.
  • Necessary switches, fuses and screen-printed front plate.
