What is a Resisteel® Broaching Tool?

The Resisteel® broaching tool is a premium-grade installation tool used when mounting Clinserts into hard materials. It is designed to pre-broach the slots needed for the insert’s Clins to anchor securely.
In materials harder than 30 HRC or 300 Vickers , the Clins cannot cut their own path — that’s where the broaching tool comes in. It creates precise slot paths for smooth and secure installation.
Why Resisteel®?
What sets this tool apart is the Resisteel® material : a proprietary, ultra-hard steel developed for extreme wear resistance. While standard broaching tools can wear down quickly in demanding materials like Inconel or titanium, Resisteel® stays sharp — offering longer lifespan and more consistent results.
The result? Fewer tool changes, better installations, and reduced downtime.
When should you use it?
Use a Resisteel® broaching tool when:
- Installing Clinserts into hard metals (above 30 HRC / 300 Vickers )
- Working with alloys like stainless steel , Inconel , or titanium
- You want a longer lifespan for your broaching blades
- You're aiming for consistent, repeatable installs with minimal tool maintenance
How to use the Resisteel® Broaching Tool
- Install the Clinsert into the hole until the Clins touch the parent material.
- Mark the Clins’ positions , then remove the insert.
- Align the broaching tool’s blades with your markings.
- Drive the tool into the material using a hammer or press.
- Remove the tool and reinstall the Clinsert.
- (Optional) Re-run the tap to clear out any burrs.
Applicable for metric threads M5 and up, and imperial 1/4" and up.

Need to Replace the Blades?
Resisteel® tools are designed to last — but when it’s time, you can easily replace the broaching blades.
