Choosing between workholding fixturing metrology tools often comes down to whether you need a specifically identified EDM holder or a clearly specified steel fixture block. Both options are used and intended for machining-related workholding, but they take notably different approaches-and their listed prices are separated by $1,475.
Quick verdict
Choose the System 3R EDM Holder Fixture Tooling Block Workholding Fixture / Tooling Block when an EDM Holder is the central requirement and the System 3R name is the fit for your existing tooling plan. It is the more expensive route at USD 1,750.00.
Choose the Mecatool Steel Rectangular Fixture Block Workholding Block, MPN C 597250 EDM when you specifically want a steel, rectangular fixture block with MPN C 597250. At USD 275.00, it is the lower-priced option and has the more detailed material and shape description.

Where each option wins
System 3R wins on EDM-holder focus. Its item type is explicitly identified as an EDM Holder, and its title centers on fixture tooling and workholding. That makes it the more direct choice for a selection centered on an EDM holder rather than a general block description.
Mecatool wins on defined block attributes. The Mecatool name is attached to a steel fixture block with a rectangular shape and a specific MPN. Those concrete identifiers are useful when the decision begins with block material, block form, or the C 597250 designation. Its lower listed price also keeps the initial outlay far below the System 3R option.
Product notes
System 3R EDM Holder Fixture Tooling Block Workholding Fixture / Tooling Block
The reason to select the System 3R option is straightforward: it is identified as an EDM Holder, not merely as a fixture block. The title also calls out both fixture tooling and workholding, while the stated purpose is to hold and position a workpiece during machining. For a shopper whose requirements are already organized around a System 3R EDM-holder format, that direct naming can matter more than a broader block description. The limitation is its USD 1,750.00 listed price, which places it at the top of this two-item comparison. It is also used and sold as-is, so it is a choice for buyers comfortable selecting a used EDM-holder tooling block rather than prioritizing a lower entry price.
Mecatool Steel Rectangular Fixture Block Workholding Block, MPN C 597250 EDM
The Mecatool option is the clearest match when the desired form is a steel rectangular fixture block. Its title and attributes identify the block material, fixture-block type, rectangular shape, and MPN C 597250; it is also described in an AGIE wire EDM context. This specificity gives the Mecatool block a focused identity for shoppers comparing block-oriented workholding tools. At USD 275.00, it is the less costly option in the pair. Its limitation is that it is used and sold as-is, and its stated form is specifically rectangular rather than the EDM Holder designation used by the System 3R option. Select it for the defined steel-block format, not as a substitute for an explicitly labeled EDM Holder.
Final choice by use case
Pick the System 3R EDM Holder Fixture Tooling Block Workholding Fixture / Tooling Block if your decision is driven by the EDM Holder item type and System 3R fixture-tooling naming. Pick the Mecatool Steel Rectangular Fixture Block Workholding Block, MPN C 597250 EDM if a rectangular steel fixture block with a named MPN is the priority and the lower USD 275.00 listed price better suits the purchase. The key distinction is not condition-both are used-but whether your workholding need is holder-specific or block-specific.
