When you're setting up workholding for machining or EDM, the first question is usually whether you need a general-purpose fixture or a dedicated one. This head-to-head compares a used System 3R EDM holder fixture tooling block listed at $1,750.00 with a new Raptor RWP-019SS dovetail fixture listed at $407.96. The price difference is more than $1,300, but that's not the only factor. One is for EDM tooling, the other is a dovetail fixture for parts with a .375-inch dovetail. How you use each one will determine which is worth the spend.
Quick Verdict
If EDM workholding is your day-to-day job, the System 3R block deserves serious attention despite the higher listed price. If you need a dovetail fixture at a lower listed price, the Raptor will likely serve you better. The right pick depends on how your parts need to be held.

Where Each Wins
System 3R EDM Holder
This is the pick for EDM-specific setups. The tooling block design and EDM holder item type point to a fixture meant to hold workpieces during electrical discharge machining. It's sold as-is, but all components work as designed. This is a specialized fixture, not a general-purpose block.
Raptor Dovetail Fixture
This wins for dovetail workholding. It's made from stainless and built around a specified dovetail width. The dimensions of 2.50 x 1.00 x 1.25 give you a compact fixture that fits into a smaller work envelope. The listed price is notably lower than the System 3R, making it an easy entry point if you're just starting to work with dovetail fixtures.
Product Notes
System 3R EDM Holder Fixture Tooling Block Workholding Fixture / Tooling Block
Choose this tooling block if your process centers on EDM and you're looking for a holder fixture from System 3R. It's sold as-is, so it carries some risk, though all components work as designed. That 'as-is' caveat is the main limitation to weigh. The EDM holder type suggests it's meant for a specific class of workholding, so it's not a general-purpose fixture. For shops that need a dedicated EDM tooling block, this could be a way to expand capability without buying new. If you're not used to buying workholding with an 'as-is' note, the higher listed price compared to the Raptor gives you another reason to pause.
Raptor RWP-019SS Dovetail Workholding Fixture Stainless .375
This is the lower-priced option and it comes without the 'as-is' caveat. The construction and the specified dovetail width make it a focused choice for parts that match that dimension. Its compact dimensions (2.50 x 1.00 x 1.25) keep it easy to fit into a workholding setup. The limitation is the same focus: if your workpieces don't have a matching dovetail, this fixture isn't built for them. If you regularly cut dovetail parts to that spec, the lower price makes it a practical place to start.
Final Choice by Use Case
Choose the System 3R EDM Holder if you need an EDM-specific tooling block, prioritize the System 3R format, and are comfortable with an 'as-is' purchase. Choose the Raptor Dovetail Fixture if you work with .375-inch dovetail parts and want a lower-priced fixture.
