Our verdict

A 0.1 hp pencil grinder for detail work that matches its 51706 sibling on power, though its lower rating makes checking the 51706 first worthwhile.

Overview

The Dynabrade 51700 is a 0.1 hp straight-line pencil grinder built for light deburring and detail work, the same compact format as Dynabrade's other pencil grinders. Model 51700 carries a lower average rating than the newer 51706, so it's worth comparing the two before choosing.

Like the rest of Dynabrade's pencil-grinder line, the 51700 favors control over power, aimed at fine detail work rather than stock removal. It shares the 0.1 hp rating and straight-line format with sibling model 51706, but its lower average rating on Amazon is worth weighing against the 51706 before deciding between the two.

Who it's for

Suits the same detail-finishing and small-part deburring work as other Dynabrade pencil grinders. Given the rating gap versus the 51706, a buyer choosing between the two models should weigh that difference first.

Pros and cons

Pros
  • Compact pencil format for detail work
  • Same 0.1 hp control-focused output as the 51706
Cons
  • Lower average rating than sibling model 51706
  • Not built for heavy material removal
  • Requires a compressed air supply

Performance notes

The 0.1 hp motor and straight-line body work the same way as the rest of Dynabrade's pencil grinder line, geared toward light, controlled cuts on small parts. As a pneumatic tool, its output depends on the shop air supply feeding it.
