feature The expected modern reciprocating saw features, such as tool-less blade changes and an adjustable shoe, mean less time looking for accessory tools and more time slicing through the hardest materials.
feature The best feature of the Bosch RS428 might be its superior, patented, anti-vibration technology. With this system, operators can work all day with this reciprocating saw without experiencing the fatigue that lesser saws induce. For demo work, this is practically must-have benefit.

Review

Bosch has made several improvements to the RS428 in response to customer suggestions about its predecessor model, the RS320. This latest revision is lighter, more powerful and has impressive cutting power.

The Bosch anti-vibration system works as advertised. Nearly all the reciprocating motion is damped out. With a pair of work gloves, you will experience super-smooth operation that does not leave your hands tingling after an hour of use. Coupled with the electronically controlled speed under any load, you will start using the word “butter” a lot to describe cuts through even thick steel members.

It does not seem to be advertised, but this saw has a “soft-start” feature, which brings the blade up to full speed over one or two seconds after you squeeze the trigger. This may feel slightly odd if you have not experienced this behavior before, but it provides safe, stable movement when starting the blade in an in-progress cut.

The constantly on orbital motion may bother some potential buyers, but the motion seems less than other saws that have an orbital on-off switch. In other words, it is there but there is some question as to how much efficiency it adds to the cut.

Given Bosch’s reputation for quality and the way they put together this reciprocating saw, it is strange that they only offer a single year of warranty. Furthermore, why a saw this good is relegated to a carrying bag instead of a solid case seems odd, but many of Bosch’s products come that way. Bags are harder to clean and do not provide the same protection against bumps. If you happen to have your old RS320 hard case, the RS428 should fit in it nicely.

prosPros

  • Powerful motor
  • Constant orbital action
  • Constant speed under load
  • Excellent power to weight ratio
  • Generous 12 ft. cord

consCons

  • A bag is provided instead of a hard shell case

verdictOur Verdict

For a mid-range reciprocating saw, the Bosch RS428 stands up well to its competition. The serious DIYer will appreciate its power and smooth cutting. On demo jobs, the anti-vibration technology will provide workers with a saw that goes the distance without wearing out the operators.
