Erowa vs. System 3R: Which Workholding System Is Right for You? 

Choosing between System 3R and Erowa-compatible tooling isn’t just about brand preference—it’s about ensuring compatibility, maximizing uptime, and eliminating costly setup errors. If you’re unsure which tooling ecosystem fits your EDM or CNC workflow, this breakdown is for you. 

Why Compatibility Matters 

When every micron counts and downtime eats into your margins, tool compatibility is key. Whether you’re machining complex molds, aerospace parts, or high-volume automotive components, your tooling should work with you, not against you. 

Rapid Holding Systems (RHS) eliminates the guesswork with 100% compatible Erowa ITS and System 3R Macro tooling—engineered for performance, priced to fit your budget. 

Tooling System Overview 

System 3R Compatible Workholding Tools 

RHS Macro Systems seamlessly mirror System 3R Macro tooling, offering North American shops a full line of reliable, precision-engineered workholding solutions—at 40–50% of OEM cost. 

These tools are optimized for both EDM and CNC applications, offering fast setup, repeatability, and modularity. Our tools are built to match System 3R standards in every detail—without the premium price. 

EROWA ITS Compatible Tooling 

Built to seamlessly integrate with Erowa ITS systems, RHS delivers a fully compatible lineup tailored for demanding EDM applications. 

Erowa tooling from RHS is known for its stronger palletization profile, making it ideal for setups requiring extra rigidity and clamping force—especially in sinker EDM and precision CNC milling. 

Which Should You Choose? 

Choose EROWA-Compatible Tooling if you: 

• Need high rigidity and strong palletization for heavier setups 

• Run sinker EDM or high-force CNC operations 

• Want to ensure tight clamping with minimal deflection 

• Prefer ITS-style pre-mounted electrode holders 

Choose System 3R-Compatible Tooling if you: 

• Prioritize speed, flexibility, and faster job changeovers 

• Use wire EDM or do high-mix machining
