What to Look for in an Oscillating Multi Tool for Metalwork
Metal cutting demands a tool with high oscillation per minute (OPM) and consistent torque. A wider oscillation angle (3-4 degrees) helps remove material faster. Variable speed control is essential for working with different metals like aluminum versus hardened steel. Look for a tool with a robust blade clamp system, such as OIS or Starlock, to prevent blade slippage during heavy cuts. Battery-powered models offer portability, but corded tools provide unlimited runtime for extended grinding or sanding tasks.
Mistakes to Avoid When Buying
Do not buy a tool with a low OPM range (below 10,000) as it will struggle to cut through steel. Avoid models with a fixed speed setting because you need slow speeds for precision cutting and high speeds for aggressive material removal. Also, check the blade compatibility: some tools only accept proprietary blades, limiting your options for metal-specific accessories. Finally, do not overlook the vibration control feature, as prolonged metalwork can cause hand fatigue.
Milwaukee M12 Fuel 2526-20
Best Overall for MetalworkPros
- Powerful brushless motor for tough cuts
- Compact and lightweight for tight spaces
- Excellent variable speed trigger
Cons
- Battery and charger sold separately
- Blade change requires tool
The Milwaukee M12 Fuel is a favorite among metalworkers for its high torque output in a small package. Owner reviews consistently praise its ability to cut through 1/4-inch steel plate without bogging down. The variable speed trigger gives you precise control for tasks like cutting conduit or grinding welds.
The tool uses the M12 battery system, which is shared with many other Milwaukee tools, making it a smart investment for existing users. However, the lack of a quick-change blade system means you need an Allen key for swaps, which can slow down workflow. Overall, it is the top choice for demanding metalwork.
Bosch GOP 12V-28
Best Corded BudgetPros
- High OPM for fast cutting
- Starlock blade system for quick changes
- Constant electronic speed control
Cons
- Limited to corded use
- Vibration can be high at top speed
The Bosch GOP 12V-28 is a reliable corded option that offers a high oscillation rate of 28,000 OPM. This makes it very effective for cutting through metal sheets and pipes quickly. Owner reviews highlight its consistent performance under load, thanks to the constant electronic speed control that maintains speed even when cutting thick steel.
The Starlock blade system allows for tool-free blade changes, which is a major advantage for efficiency. However, the cord can be restrictive for overhead work or tight spaces. It is an excellent choice for workshop use where power is always available.
DeWalt DCS356C1
Best Battery LifePros
- Long runtime with 3.5 Ah battery
- Quick-change blade clamp
- Low vibration design
Cons
- Heavier than some competitors
- Battery can be bulky
The DeWalt DCS356C1 is part of the 20V MAX system and comes with a 3.5 Ah battery that provides extended runtime for metal cutting projects. Owner reviews note that it can cut through multiple pieces of steel tubing on a single charge. The variable speed trigger with a lock-on button is useful for continuous cuts.
The quick-change blade clamp allows for fast swaps without tools, which is a big plus when switching between cutting and grinding. The tool is slightly heavier than the Milwaukee, but the reduced vibration makes it comfortable for longer sessions. It is a solid choice for those already in the DeWalt ecosystem.
Makita XMT03Z
Best LightweightPros
- Very lightweight for its power
- Tool-less blade change
- Low noise operation
Cons
- Battery not included
- Less torque than heavier models
The Makita XMT03Z is designed for users who need a lightweight tool for overhead metalwork or tight spaces. It weighs only 2.9 lbs with the battery, reducing fatigue during long sessions. Owner reviews mention it handles thin sheet metal and aluminum profiles well, though it struggles with thick steel.
The tool uses the Makita 18V LXT system, which is one of the largest battery platforms. The tool-less blade clamp is easy to operate. It is best for light to medium metal cutting tasks, such as cutting ductwork or removing rust from car panels.
Ryobi P450
Best ValuePros
- Affordable price point
- Compatible with Ryobi ONE+ system
- Includes a carrying case
Cons
- Lower max OPM than others
- Vibration can be high
The Ryobi P450 is the best budget option for DIY metalworkers. It is part of the Ryobi ONE+ system, making it a great addition for homeowners who already own Ryobi tools. Owner reviews say it works well for cutting thin metal sheets, rebar, and for removing old paint or rust from metal surfaces.
The tool has a variable speed dial rather than a trigger, which some users prefer for consistent speed. It is not as powerful as the Milwaukee or DeWalt, so it may struggle with thicker steel. However, for the price, it offers good value for occasional metalwork projects.
FAQs
What is the best oscillating multi tool for cutting steel?
The Milwaukee M12 Fuel is the best for cutting steel due to its high torque and variable speed control.
Can I use a wood blade on metal?
No, you should use a bi-metal or carbide blade specifically designed for metal cutting to avoid damage.
Is a corded or cordless tool better for metalwork?
Cordless tools offer portability, but corded tools provide unlimited runtime for heavy grinding tasks.
What OPM is needed for cutting metal?
Look for a tool with at least 15,000 OPM for efficient cutting of steel and other metals.
Do I need a brushless motor for metalwork?
A brushless motor is recommended for better torque, longer runtime, and durability under heavy loads.
What blade system is best for metal cutting?
Starlock or OIS systems are best as they provide secure blade attachment and quick changes.
Can an oscillating tool cut through rebar?
Yes, with a proper carbide blade, an oscillating tool can cut through rebar, but it may be slower than a grinder.
How do I reduce vibration when cutting metal?
Use a tool with anti-vibration technology and ensure the blade is sharp and properly secured.
Is the Ryobi P450 good for metalwork?
It is good for light metalwork like cutting thin sheets or removing rust, but not for heavy steel.
What is the difference between oscillating angle and OPM?
Oscillation angle is the side-to-side movement, while OPM is the speed; both affect cutting efficiency.
Our verdict
For the best oscillating multi tool for metalwork, the Milwaukee M12 Fuel 2526-20 is our top pick due to its powerful motor and compact design. If you are on a budget, the Bosch GOP 12V-28 offers excellent corded performance for less money.
