Conduct endurance tests of 18-volt cordless reciprocating saws to determine work that can be anticipated at fire/rescue incidents.Subject:  Cordless Reciprocating Saws, Part 4Topic:  Endurance Testing of 18-Volt Cordless Reciprocating SawsObjective...

Using DeWalt’s original XR2 batteries in the Nomad battery pack, saw operators were able to complete the following evolutions:

  • Seven A-pillar cuts
  • Two B-pillar cuts
  • Five C-pillar cuts
  • Seven Nader pin cuts
  • Four hinge leaf cuts
  • One brake pedal shaft cut
  • Four steering wheel ring cuts
  • One steering column cut.

This test exhausted several saw operators and consumed six DeWalt nine-inch/14-tpi blades. In two other tests, the Nomad powered the saw through 12 minutes, 13 seconds of actual cutting time and 12 minutes, 43 seconds of aggressive cutting. The last test wore out three Torch blades and let me complete the following:

  • Eight A-pillar cuts
  • Four B-pillar cuts
  • Four Nader pin cuts
  • Four hinge leaf cuts
  • Two steering wheel ring cuts

When the Nomad pack was equipped with fully charged DeWalt XR+ batteries, cutting time increased to a remarkable 18 minutes, 36 seconds.
