Selecting workholding fixturing metrology gear starts with a practical divide: do you need a general-purpose vise for milling and drilling, or a fixture intended for EDM and more specialized part holding? The four options here span a listed-price range of $91.10 to $1,750, but they are not interchangeable versions of the same tool. Start with the workholding method your operation calls for, then use material, condition, and stated dimensions to narrow the field.
Quick take
- Choose the 6'' Machine Vise Precision CNC Milling Machine Bench Clamp Vice Lock Vise when a 6-inch jaw-width vise is the central need for milling, drilling, or precision-parts finishing.
- Choose the Raptor RWP-019SS Dovetail Workholding Fixture Stainless .375 when a .375 dovetail fixture in stainless steel is the relevant format.
- Choose the Mecatool Steel Rectangular Fixture Block Workholding Block, MPN C 597250 EDM for a used steel rectangular fixture block associated with wire EDM work.
- Choose the System 3R EDM Holder Fixture Tooling Block Workholding Fixture / Tooling Block when an EDM holder from System 3R is the required tooling category and the higher listed price suits the job.
Listed price comparison
| Workholding option | Condition | Listed price | Relative price |
|---|---|---|---|
| System 3R EDM Holder Fixture Tooling Block Workholding Fixture / Tooling Block | Used | $1,750.00 | |
| Mecatool Steel Rectangular Fixture Block Workholding Block, MPN C 597250 EDM | Used | $275.00 | |
| Raptor RWP-019SS Dovetail Workholding Fixture Stainless .375 | New | $407.96 | |
| 6'' Machine Vise Precision CNC Milling Machine Bench Clamp Vice Lock Vise | New | $91.10 |
Decision matrix
For conventional milling and drilling: The findmall machine vise is the direct match. Its listing specifically positions it for precision milling, grinders, NC/CNC machines, milling, and drilling, while its jaw dimensions give it a clearly stated holding format.
For dovetail-based holding: The Raptor RWP-019SS is the focused choice. Its stainless construction and .375 dovetail width distinguish it from the rectangular EDM block and bench vise.
For a rectangular steel fixture block: Mecatool's C 597250 is the relevant option. The rectangular shape, steel block material, and fixture-block designation make the format clear.
For an EDM holder tooling block: The System 3R option belongs in the conversation when the requirement is specifically an EDM holder rather than a vise or a dovetail fixture.
Product notes
System 3R EDM Holder Fixture Tooling Block Workholding Fixture / Tooling Block
This used System 3R tooling block is the specialized pick for an operation that calls specifically for an EDM holder fixture. The description frames its role as holding and positioning a workpiece during machining, and its Item Type is identified as an EDM Holder. That makes it a more direct fit for EDM-oriented tooling needs than the 6-inch machine vise or the Raptor dovetail fixture. The key limitation is its $1,750.00 listed price, the highest of the four, alongside its used condition. It is best treated as a purpose-specific tooling-block choice rather than a broad substitute for a conventional milling vise.
Mecatool Steel Rectangular Fixture Block Workholding Block, MPN C 597250 EDM
Pick the Mecatool C 597250 when the desired form is a steel, rectangular fixture block. Its title and attributes consistently identify a rectangular steel workholding block, while the description places it in wire EDM use on an Agie machine. The stated MPN, C 597250, also provides a concise identifier for teams matching an existing tooling reference. Its limitation is that it is used, and its stated use case is narrower than the findmall vise's milling and drilling orientation. At $275.00, it sits well below the System 3R holder in listed price while remaining a fixture-block format rather than a jawed vise.
Raptor RWP-019SS Dovetail Workholding Fixture Stainless .375
The Raptor RWP-019SS is the natural selection when a stainless .375 dovetail fixture is the needed workholding format. Its description identifies a .375-inch dovetail width and gives dimensions of 2.50 x 1.00 x 1.25, making this a clearly dimensioned fixture rather than a general bench clamp. It is also listed as new, which separates it from the two used EDM-oriented blocks. The limitation is specialization: a dovetail fixture serves a different holding approach from the 6-inch-jaw machine vise, so it is not the direct answer for buyers seeking a standard vise layout. Its listed price is $407.96.
6'' Machine Vise Precision CNC Milling Machine Bench Clamp Vice Lock Vise
For milling, drilling, and precision-parts finishing, the findmall 6-inch machine vise is the most general-purpose choice in this group. It is listed as new and pairs an HT250 gray cast-iron body with 45# steel jaws. The stated 6-inch jaw width, 5.9-inch jaw opening, and 1-3/4-inch jaw height give shoppers concrete holding dimensions to work from. It also has the lowest listed price at $91.10. Its limitation is equally clear: this is a jawed milling vise, not an EDM holder, rectangular fixture block, or .375 dovetail fixture. Choose it when that conventional vise format is the intended tool.
Final recommendation by use case
Choose the findmall 6'' Machine Vise for a conventional milling or drilling vise with stated 6-inch jaws. Choose the Raptor RWP-019SS when the job calls for a stainless .375 dovetail fixture. Choose the Mecatool C 597250 for a used rectangular steel fixture block associated with wire EDM. Choose the System 3R EDM Holder Fixture Tooling Block when an EDM holder is the defining requirement and a used System 3R tooling block fits the planned application.
