TL;DR: Oscillating multi-tools do what nothing else can — flush cuts, grout removal, tight-space cuts, scraping, sanding. The Milwaukee M18 FUEL 2836-20 is the best cordless option if you’re in the M18 ecosystem. Bosch GOP18V-28N if you need Starlock blade compatibility for professional work. Metabo HPT GOP18V if you want to spend under $100 on a solid tool. All four picks below are cordless, brushless, and actually worth owning.

What Oscillating Multi-Tools Actually Do (That Other Tools Can’t)
An oscillating tool’s blade moves side to side at 10,000–20,000 OPM (oscillations per minute) through a tiny arc — typically 3°. That small, controlled motion lets it do things circular saws and jigsaws can’t:
- Flush cuts: Cut a nail or screw flush with the wood surface without damaging the material behind it
- Plunge cuts: Start a cut in the middle of a surface, not from the edge — essential for drywall cutouts and flooring repairs
- Grout removal: A grout blade fits tight tile joints and removes old grout without cracking tiles
- Scraping: Remove tile adhesive, paint, caulk, and adhesive from any surface
- Sanding in corners: Triangular sanding pads reach into 90° corners where orbital sanders can’t go
If you’ve ever tried to make a plunge cut with a circular saw or remove a doorstop trim piece without a multi-tool, you already understand why these are worth owning.
Milwaukee M18 FUEL 2836-20 — Top Pick
The 2836-20 is the best cordless oscillating tool available right now. Milwaukee got everything right: POWERSTATE brushless motor for consistent power delivery, CONSTANT RESPONSE electronics that maintain blade speed under load, and AVS (Anti-Vibration System) that actually reduces fatigue on long cuts.
What sets the 2836-20 apart from every other oscillating tool is the 4° arc angle — slightly wider than the 3° standard. That extra arc translates to faster cutting speed without sacrificing control. On grout removal and flush cuts, you feel the difference.
The OPEN-LOK blade attachment system takes seconds without tools. It also accepts universal OIS blades with an adapter, so your existing blade collection isn’t wasted.
- Motor: POWERSTATE brushless
- Arc angle: 4°
- OPM: 10,000–18,000
- Blade system: Milwaukee OPEN-LOK (accepts OIS universal blades with adapter)
- Bare tool only — requires M18 battery (not included)
Milwaukee is a Home Depot exclusive in the US — you won’t find it at full retail on Amazon. See our oscillating multi-tool blades guide for the best blades to pair with this tool.

Bosch GOP18V-28N — Best for Professionals
The Bosch GOP18V-28N earns the professional pick because of blade compatibility. Bosch’s Starlock MAX system is the most widely-adopted quick-change blade platform in the industry — the blades are interchangeable with any Starlock or Starlock Plus tool, and Bosch makes the best oscillating blades available.
The 28-piece accessory set included with the GOP18V-28N is the most comprehensive starter kit on this list: tile blades, carbide grout blades, wood flush-cut blades, scraper, and sanding pads cover every application out of the box.
At $200, it’s a professional tool at a professional price, but one that pays for itself if you do tile work, flooring installs, or remodeling where blade quality matters.
- Motor: Brushless
- Arc angle: 3.2°
- OPM: 10,000–20,000
- Blade system: Starlock MAX (compatible with Starlock and Starlock Plus)
- Accessory set: 28 pieces included

Metabo HPT MultiVolt GOP18V — Best Value
The Metabo HPT MultiVolt oscillating tool delivers brushless performance for $89. At that price, it’s hard to criticize — it’s a brushless tool with a universal blade adapter, variable speed, and solid build quality. For occasional use — a flooring project here, a grout job there — this is enough tool.
The MultiVolt gimmick (18V batteries work as 18V, 36V MultiVolt batteries auto-switch to 36V) isn’t relevant here since oscillating tools don’t need that kind of power — but it means this tool is forward-compatible if you ever invest in the Metabo HPT 36V system.
- Motor: Brushless
- Arc angle: 3.4°
- OPM: 7,500–18,000
- Blade system: Universal adapter included (fits OIS, Starlock, Fein MultiMaster)
Price at time of writing: $89 (bare tool). Buy Now on Amazon
DeWalt ecosystem users: DeWalt makes the DCS356B 20V MAX Atomic oscillating tool. It uses Quick-Change blade attachment and fits the full DeWalt 20V MAX ecosystem. Search your preferred retailer for current availability and pricing.
Buying Guide: How to Choose a Cordless Oscillating Multi-Tool
Blade Compatibility: The Most Important Spec
Before you buy any oscillating tool, check the blade system. There are three main standards:
| Blade System | Who Uses It | Compatibility |
|---|---|---|
| Starlock / Starlock MAX | Bosch (primary), some Fein | Best blade selection. Starlock MAX fits Starlock and Starlock Plus, not vice versa. |
| OIS Universal | Milwaukee OPEN-LOK, DeWalt, Ridgid, many others | Wide aftermarket support. Most cheap blades use this standard. |
| Brand-specific | Some older Fein tools | Limited to brand blades. Avoid unless you’re buying a Fein tool. |
For most users, OIS universal compatibility (Milwaukee, DeWalt, Metabo HPT) means the widest accessory selection at the lowest prices. For professional tile and grout work, Starlock MAX (Bosch) is worth the investment.
Arc Angle: Speed vs Control
Arc angle determines how fast the blade moves through material. Standard is 3° — higher (3.4–4°) cuts faster but with slightly less precision. For most applications the difference is negligible. Milwaukee’s 4° arc on the 2836-20 is a genuine advantage on straight cuts in thick material.
Battery Capacity for Oscillating Tool Work
Oscillating tools are power-efficient — you can run most jobs off a 2.0Ah battery. The exception is grout removal in a large bathroom or extended scraping sessions, where a 4.0Ah or 5.0Ah battery gives you enough runtime to finish without a charge break. See our battery platform comparison for which batteries give the best runtime-to-weight ratio.
Frequently Asked Questions
What’s the best oscillating tool for tile removal?
The Bosch GOP18V-28N with a Starlock carbide grout blade is the best combination for tile work. Starlock blades are the most durable available, and the 28-piece accessory kit includes a proper carbide grout blade. Milwaukee 2836-20 is also excellent with the right carbide blade.
Are oscillating multi-tools actually worth it?
Yes, for three specific applications: flush cuts that no other tool can make, plunge cuts in the middle of surfaces (drywall, floors), and grout/caulk removal. If you’re doing a bathroom renovation, flooring install, or any trim work, you’ll reach for this tool constantly. If you mostly build from scratch, an oscillating tool is less essential.
Can you use Milwaukee blades on a Bosch oscillating tool?
Not directly — Milwaukee uses the OPEN-LOK system while Bosch uses Starlock. However, the Metabo HPT GOP18V comes with a universal adapter that fits both OIS (Milwaukee-standard) and Starlock blades. For Milwaukee-to-Bosch compatibility specifically, you’d need a third-party OIS-to-Starlock adapter.
