🟡 PwnCNC Lever Clamp — The Original Low-Profile CNC Workhorse
The PwnCNC Lever Clamp was our very first product back in 2019—and it’s still one of our most beloved. Trusted by thousands of hobbyists and makers, this clamp hasn’t needed a single design change since launch. Why? Because it just works.
⚙️ Key Features
🔁 Reversible, Dual-Sided Design
Clamp thinner materials with precision thanks to the rear ledge—perfect for delicate or slim stock. Flip it around for a standard clamping profile.
📏 Tool-Free Adjustment
Each clamp includes a built-in slider mechanism, allowing you to quickly move the fulcrum point without disassembling the clamp. This lets you adapt to different stock sizes with ease, keeping the clamp level and securely in place.
🛡️ Bit-Safe, Low-Profile Design
At less than 6mm tall, this clamp sits low and stays out of your spindle’s way. If a bit does collide, the clamp’s forgiving material ensures your tool remains undamaged—simply replace the clamp and keep carving.
💡 Compact & Lean
Designed for tight setups, the clamp’s narrow footprint makes it ideal for dense layouts and small bed spaces.

A little creativity—we’ve seen these clamps used in every way imaginable!
⚠️ Note: Minor fraying within the slider track is normal and expected due to the 3D printing process. It won't impact performance.

These clamps are the go-to solution for makers who want speed, simplicity, and safety in every carve. Try one and you’ll see why it’s our best-selling classic.
Theses are the best clamps I've used to date. Adjustable and strong. But not to harsh the mess up bits if you hit them. Don't ask how I know. Lol.
Works as pitched
I've had these clamps since November and just now used them. They're so nice I was scared to tear them up. I tend to go through clamps easily.... wish I would have opened them months ago! The sliding mechanism holds amazing thanks to the grooves. Fits the screws that came with my shapeoko too! Held my piece down wonderfully! My bit already went into one too.. Definitely going to order more after I tear these ones up!!
I received my products in a timely fashion and the website made it quick and easy to order! I love this company and they have great customer service and respond in a timely manner! The only thing I wish was different is that the IoT Relay had in the description that it would not work and was only designed to work if you had a PWN spindle. I can’t use it until I have the money to upgrade to their spindle, which I already planned on doing so anyway.
Been using them for years, good quality
