When you're shopping for separation equipment, the price spread can be striking. One product in this head-to-head lists for $1,886.00; the other for $24.42. Both are sold as separators, but they solve completely different problems. The TECHTONGDA 208-240V Industrial Cutting Fluid Oil-Water Separator is built to clean machine tool coolant. The ASR Outdoor Magnetic Pickup Tool 2-Pack is a handheld magnet for collecting metal debris. The right choice depends entirely on which material you need to separate.
Quick verdict
For a shop that maintains cutting fluid, choose the TECHTONGDA: it skims floating oil to extend fluid life and protect machining accuracy. For a garage or small workspace, choose the ASR Outdoor pair: the two quick-release magnets make fast work of ferrous scraps. Your job determines the right tool.
The comparison table below highlights the fundamental differences.
| Aspect | TECHTONGDA 208-240V Oil-Water Separator | ASR Outdoor Magnetic Pickup Tool 2-Pack |
|---|---|---|
| Listed price | USD 1,886.00 | USD 24.42 |
| Primary separation target | Floating oil in cutting fluid | Magnetic metal debris |
| Power source | 208-240V, 3-phase | Handheld / manual |
Where each product wins
The TECHTONGDA wins for any shop that uses cutting fluid in a machine tool. It continuously separates floating oil, which keeps the coolant in condition to protect tooling and parts. The result is longer fluid service, better machining accuracy, and less sludge, with a cleaning valve to handle the buildup. This is a sump-level solution, not a spot cleaner.
The ASR Outdoor wins for anyone who wants to clear ferrous scrap without bending over or sweeping. It's a two-piece set you can keep within reach, and using it takes no setup or power. The compact magnets store easily, so you can grab one the moment you drop a box of screws.
TECHTONGDA 208-240V Oil-Water Separator
The reason to pick this separator is cutting fluid longevity. By separating floating oil from coolant, it extends the service life of the fluid and helps maintain machining accuracy. It also recovers the separated oil for reuse and has a cleaning valve for sludge. For a machining operation, keeping coolant free of floating oil is a constant task, and this skimmer automates that process. The limitation is the power requirement: it is built for a 208-240V, 3-phase supply, so it is only practical in a shop with that electrical service. It's a single-purpose industrial tool, so if your operation doesn't involve cutting fluid, you won't use it.
ASR Outdoor Magnetic Pickup Tool 2-Pack
The reason to pick this set is that it gives you two handheld magnets in one kit. Each magnet can grab up to 8 lb of ferrous metal, and the rubberized quick-release handle lets you drop debris without touching it. The compact size-under five inches tall-makes these easy to store near a workbench. That simplicity is exactly why many garage shops keep one in a drawer for unexpected spills. The limitation is material type: only magnetic metals are captured. It will not separate oil, water, or non-magnetic materials, so it is a useful shop accessory but not a replacement for a coolant-management system.
Final choice by use case
Match the separator to the material you need to separate. If it's oil floating in cutting fluid, buy the TECHTONGDA. If it's metal debris on a floor or work surface, the ASR Outdoor 2-pack is the practical, low-cost tool for the job. There is no single winner across every shop-just the right tool for the specific mess you're cleaning up.
