The vise jaws hold the workpiece; the magnet secures the vise base to its support. That flexibility is useful for movable setups, but it does not make every surface compatible or every operation safe.
How a magnetic-base vise works
With a portable magnetic-base vise, the magnetic base attaches to a suitable magnetizable support, while the vise’s jaws clamp the workpiece. You can move the vise to a useful position, align the work, then engage the product’s full-hold setting. This separates two jobs: the magnet anchors the vise, and the jaws grip the material.
FEIN describes its VersaMAG 160 L system as allowing positioning at 30% magnetic hold followed by full holding at 100%. It also has integrated depth and back stops for repeat setups. These are features of that FEIN product, not universal specifications or a published accuracy guarantee for magnetic vises.
What surfaces will a magnetic vise stick to?
A magnetic base needs a magnetizable surface with good contact. For the cited FEIN VersaMAG, the instruction manual calls for a flat surface that is magnetizable, clean, rust-free, free of coating and ice, and at least 4 mm thick. It also requires firm footing. Treat those as requirements for this product; another vise may specify different limits.
#1 Best Overall
- Two Pack: The set includes 6 inches soft standard pads and 5-1/2 inch multi-groove jaw pads. Works with most Bench Vises, Clamps, Drill Presses, Millers, and more
- Non-Marring: Aluminum Vise Jaws with drawer-type soft pads are designed to protect hard workpieces, and the tough multi-groove pads perform well in protecting soft workpieces
- Skid-proof Surface: The drawer pads have a waffle surface to hold round or hex parts and support flat parts well. The multi-groove provides 5 round grooves and 90° & 45° clamping angles
- Strong Magnets: Embedded magnets on the pads attract them to the vise tightly, keeping vise pads securely in place and holding the workpiece better
- Multi-Purpose: These vice jaw pad sets can be used on many types of vices and help protect surfaces of wood, metal, plastic, tubing or any other workpieces used on a vice
Aluminum is not a suitable surface for a conventional magnetic base to attach to directly. However, a vise mounted on a compatible steel surface can clamp an aluminum workpiece between its jaws. Protective jaws may help when the material’s surface is easy to scratch.
What to check before choosing or setting one up
- Support surface: Check material, flatness, thickness, cleanliness, coating, rust, ice, and stability against the specific manual’s requirements.
- Jaw capacity and workpiece geometry: Compare jaw width, clamping width or opening, travel, jaw height, and the shape and size of the stock. The workpiece must fit securely within the vise’s range.
- Operation and restraint: Confirm that the manufacturer permits the intended tool and operation. Consider the expected forces and how the workpiece will be supported; follow the specified clamping instructions and use any required restraint.
- Repeat positioning: Stops or locating features can help return work to a consistent position. Do not assume they provide a particular tolerance unless the manufacturer publishes one.
- Surface protection: Consider protective jaws for delicate or finished stock, and verify that the jaw accessory fits the vise model.
FEIN VersaMAG 160 L: a portable vise example
FEIN Canada lists the VersaMAG VISE 160 L SET, product number 9 91 00 001 35 7. The figures below are the manufacturer’s model specifications, not independent test results.
Rank #2
- 【PREMIUM QUALITY STRUCTURE】- The whole bench clamp is made of high-quality material with high hardness and stiffness. Designed for long-term service time.
- 【POWERFUL CLAMPING FORCE】- After fine grinding treatment, the surface of the clamp is smooth and flat. Clamping the workpiece without shaking, and the machining accuracy is higher. Jaw Width: 6" Jaw Opening: 5.9".
- 【HIGH ACCURACY SCREW】- The screw rod is made of high strength material which is not easy to deform, wear resistance, and achieves smooth rotation. Accurate to 0.002" on parallelism and squareness.
- 【REINFORCED & ADJUSTABLE】- The solid base and swivel handle make the use more stable and convenient. Easy to operate and improving working efficiency.
- 【WIDE APPLICATION】- It is an essential tool for fitters. Most work of the fitters is completed by using the clamping vise such as sawing, filing, chiseling, and some assembly and removal jobs.
| Specification or item | FEIN-published details |
|---|---|
| Clamping width | 160 mm (6-1/4 in) |
| Jaw width | 150 mm (6 in) |
| Travel | 164 mm |
| Magnetic holding force | 12,500 N |
| Clamping force | 19,000 N |
| Included in the set | Permanent magnet and mounting plate, vise, chip tray, back stop, depth stop, two levels, hex key, and safety strap |
FEIN also lists a VersaMAG vise set with aluminum protective jaws: 108 mm clamping width, 100 mm jaw width, and 7,800 N magnetic holding power. The manufacturer describes its blank and prism jaws as protecting delicate materials and reducing wobble or slipping for suitable workpieces. Check compatibility rather than assuming these jaws fit every vise.
Is a magnetic vise strong enough for drilling or grinding?
There is no single safe answer based on a magnetic holding-force number alone. That figure is not a universal cutting-force rating: actual security depends on the support surface and contact, workpiece geometry, clamping, and the operation. The cited FEIN specifications do not establish safe loads across different setups.

For the VersaMAG, FEIN says the product may be used with hand-guided tools and drill presses, but excludes machine tools such as milling machines. Its manual also says to secure the product with the supplied safety strap and warns that an insecurely fastened workpiece can come loose and cause injury. Follow the manual for the exact model and do not treat a magnetic base as a substitute for appropriate workholding or restraint.
