Pro Tool Reviews found that the Milwaukee 2836-20 delivers outstanding vibration control and an Auto-Load variable speed dial that ramps power as pressure increases, enabling rapid material removal. The tool features a 180-degree LED work light for improved visibility in tight spaces, though Toolrev noted that blade flex at the tip can tug the tool off-line during precise straight cuts. Additionally, the threaded bolt required for accessory changes makes swapping blades slower than competing systems that use simpler lever mechanisms. This model suits professionals prioritizing speed and ergonomics over absolute precision or quick-change convenience.

Strengths
  • — Outstanding vibration control that minimizes tool fatigue during extended use.
  • — Auto-Load feature on the variable speed dial automatically ramps up power as pressure is applied to the blade.
  • — 180-degree LED work light provides superior illumination in dimly lit or tight spaces.
Watch-outs
  • — Tool-free blade change relies on a threaded bolt that requires manual unscrewing, making it slower than competing systems.
  • — Blade flex at the tip can cause the tool to tug off-line during precise straight cuts compared to stiffer competitors.
Ridgid 18V Brushless R86242B
Ranked #4 in Best Oscillating Multi-tools
Ridgid 18V Brushless R86242B
1 sourceall derived

Pro Tool Reviews found that the Ridgid R86242B dominated performance tests, cutting threaded rod in just 31 seconds and outperforming competitors like Milwaukee. The tool features a brushless motor delivering up to 20,000 OPM and a new quick-change pin system for faster accessory swaps. While some reviewers noted the vibration is slightly more noticeable than top-tier rivals, it remains well-controlled. This model is best suited for DIYers and pros seeking high-speed cutting efficiency in tight spaces without needing the JobMax modular base.

Strengths
  • — Delivers cutting speeds up to 75% faster than previous models, finishing threaded rod cuts in just 31 seconds according to Pro Tool Reviews.
  • — Features a new quick-change pin system that simplifies accessory swaps compared to the cumbersome design of older Ridgid oscillating tools.
  • — Provides three selectable speed modes combined with a variable speed trigger for precise control during detailed work like undercutting door jambs.
Watch-outs
  • — Exhibits higher vibration levels than some competing models in head-to-head comparisons, though still considered a significant improvement over the predecessor.
  • — Uses a multifinger paddle trigger rather than a traditional slide switch with variable speed dial, which some users find less intuitive.

How they stack up

Milwaukee 2836-20 M18 Fuel Oscillating Multi-Tool

The Milwaukee 2836-20 offers superior vibration control and a wider 4.2-degree oscillation angle compared to the Craftsman V20's basic dampening and 2.8-degree angle, making it better for extended professional use. However, its threaded bolt blade change system is slower than the Ridgid R86242B’s quick-change pin mechanism, and it exhibits more blade flex during precise straight cuts than stiffer competitors like the Ryobi ONE+.

Ridgid 18V Brushless R86242B

The Ridgid R86242B dominates cutting efficiency, finishing threaded rod cuts faster than the Milwaukee M18 Fuel and featuring a wider 4-degree oscillation angle compared to the Craftsman V20’s 2.8 degrees for more aggressive material removal. Its quick-change pin system allows for faster accessory swaps than the Milwaukee 2836-20’s threaded bolt, though it exhibits slightly higher vibration levels than the Milwaukee M12 FUEL during extended use.
