Sleeker, sturdier and stronger; the next generation of Snap-on 7850 series cordless tools are sure to make technicians more productive and efficient in the service bay.  Both the Snap-on 1/2-inch drive cordless impact wrench (CT7850) and the cordless hammer drill (CDR7850H) have been re-designed to maximize performance, increase runtime and provide more durability over the life of the tools.

 “The Snap-on 7850 series of cordless tools are better than they ever have been with features that make them more productive and powerful,” said Rodger Isetts, product manager for Snap-on. “In addition, the 7850 cordless series features an 18-volt lithium battery and a state-of-the-art microprocessor-controlled trigger switch to extend both battery life and tool life.”

 The features and benefits of the Snap-on new cordless 7850 series include:

  • Digital microprocessor controlled switches will provide much longer life compared to competitive models
  • State-of-the-art IBR18650B cells for better cold temperature performance and longer life
  • Additional one-watt LED light
  • Rare-earth magnets on motors – increases motor efficiency with 15 per cent improvement over previous model, providing higher output but drawing less current so tools will run cooler and have better overall performance
  • Built-in, thermostatically-controlled fan, in CTC720 charger, designed to reduce waiting time for users

 The 1/2-inch Drive Cordless Impact Wrench (CT7850) features the following improvements:

  • Lighter for less strain and better control

 The Snap-on Cordless Hammer Drill (CDR7850) features the following improvements:

  • Enhanced battery provides 38 per cent increase in number of holes drilled in steel over the life of the battery (based on drilling in 1/8-inch thick steel using 3/4-inch unibit)
  • “Hammer drill” function useful for drilling holes in concrete, up to 1/2-inch holes
  • Smaller size for increased maneuverability
