Choosing a machine vise for your milling work usually comes down to jaw capacity versus cost. Two open-box single-station horizontal vises are worth comparing: the Precision 6" model and the Interstate 4" model. The Precision offers a much larger jaw width and opening, while the Interstate takes up less space and carries a lower listed price. Here's how to decide which one fits the kind of parts you mill.
Quick Verdict: The Precision 6" vise is the pick when you need to hold wider, heavier workpieces. The Interstate 4" vise is the pick when you want a more compact, lower-priced workholding solution and can work with a 4-inch jaw opening.
At a Glance
| Feature | Precision 6" Vise | Interstate 4" Vise |
|---|---|---|
| Listed price | USD 400.00 | USD 199.00 |
| Price bar | ||
| Jaw width | 6 in | 4 in |
| Max jaw opening | 7-1/2 in | 4 in |
| Load capacity | 7,875 lbs | 4,409 lbs |
| Condition | New - Open box | New - Open box |
Both are manual, horizontal, single-station vises from China, and they diverge most in size, capacity, and price.
Where Each Vise Wins
Precision 6" vise: This is the larger-workpiece option, with a wider jaw, a deeper opening, and a higher load capacity. The 17.2-inch overall length gives you an idea of the table space it will occupy. If your parts are big and your cuts are heavy, this is the more capable unit.
Interstate 4" vise: This is the space-saving, lower-priced option. The smaller jaw opening is a limitation, but the compact envelope makes it easier to fit onto a crowded workbench or mill table. You also avoid the extra cost of a larger vise when you don't need it.
Product Notes
#### Precision Machine Vise Single-Station 6" Jaw Width 7-1/2" Jaw Openi
At $400.00, this Precision vise asks for a bigger outlay, but it pays off when your work requires a 6-inch jaw width and a 7-1/2-inch maximum opening. The 7,875-pound load capacity is substantial for a manual single-station vise, and the description notes that it is sold as new/open box because it was used for demo/display only, never in production. It ships in the original packaging. The main limitation is the 17.2-inch overall length, so be sure your mill table has the room. If you regularly set up larger parts, this is the one that gives you the most working room.
#### Interstate Horizontal Machine Vise 4" Jaw W 4" Jaw Opening 43137447 INCOMPLETE
At $199.00, the Interstate is the lower-priced entry here and goes after a different niche: 4-inch jaw width, 4-inch opening, and 4,409-pound load capacity are well matched to small or light milling jobs. The description is upfront that it does not include a swivel base, and the title says INCOMPLETE, so you'll need to supply your own base or work without one. For shops that already have a base or don't need one, this compact vise is a straightforward way to get a new/open-box workholding setup. Its lighter capacity is the trade-off you accept for the smaller footprint.
Final Choice by Use Case
Pick the Precision 6" vise when you routinely work with larger parts that need a wide jaw opening. Pick the Interstate 4" vise when you machine smaller components, want to save table space, and prefer the smaller price tag. If you already have a swivel base or are fine working without one, the Interstate becomes an even easier choice; if you'd rather avoid re-fixturing large parts, the Precision is the stronger fit.
