Aluminum Tiger Claw

Good concept but the size of the hold-down for the supposed compatibility with T-tracks was too small. In fact, the T-track size of the equipment in my shop, is all the same, and is what I thought to be, a standardized size. I guess not but I'm not sure where you find, or on what type of equipment you find, this smaller T- track size. Anyhow, I was able to remove the lower end (the piece that slips into the T, of the track) and replace it with another, larger foot that I fabricated out of mild steel and threaded to accept the provided Allen bolts. It now works as intended and I've already used them (and will continue to do so) with great success. The only further recommendation I'd make regarding this product, merely has to do with the fact that I prefer to use thumb bolts (generally), for quicker materials clamping, without having to locate and then deal with aligning and turning an Allen wrench. I will say though, that these clamps do indeed work well and grip materials confidently. If they fit my T-tracks without modification, then I would have gladly recommended these to others.

These are really nice little low profile clamps for my Shapeoko cnc. They are made from anodized aluminum and come with the hardware and allen wrenches necessary to use them. They are very simple to use. They slide into the t-track and thighten down securely, then to clamp the workpiece, you just tighten the small allen head bolt. They grip really well and hold the workpiece securely. While they are low profile, they are tall enough to sit higher than my spoilboard and grab the workpiece, unlike some other low profile clamps I've tried. These seem to be an excellent value as well, when compared to others out there. No complaints.

I ordered this pair of clamps for my Genmitsu 4030S and they weren't really useful until I upgraded to an aluminum T track spoil board due to their limited reach. Now with the new spoil board these are versatile clamps that work well. They're nicely built with an orange anodized finish. The kit includes two clamps, hardware including T nuts that fit the slots in my new spoil board and a pair of allen wrenches. Fit and finish are very good. They're nice looking clamps.The clamps are really versatile when used with a T track spoil board. I reviewed the associated Fuzqq right angle clamp fixture and these work really well with that fixture. They did bind a little when I first tightened them, so I gave the clamp screws a shot of dry lube and they felt a lot better. Holding power is pretty good for a clamp of this type.My CNC came with steel clamps, so this pair of low profile aluminum clamps are a big improvement. IMHO they're a good value.

These low-profile aluminum side clamps are designed specifically to solve a common machining headache: keeping your workspace clear so your CNC spindle or laser module doesn't accidentally collide with bulky workholding brackets. Because they grip the stock from the side rather than pressing down from the top, they are ideal for surface milling, engraving, and pocketing across the entire face of your material.​Here is an analysis of their design, compatibility, and best practices for getting a rigid hold.​Design & Build Quality​Low-Profile Side Gripping: By applying horizontal pressure against the edge of your material, these clamps leave the top surface entirely unobstructed. This means you can run facing operations without worrying about Z-axis clearance or destroying a cutting bit on a high-profile bolt.​Aluminum Construction: Machined from aluminum, these clamps offer a great balance of durability and machine safety. If you do happen to make a programming error and nick a clamp, aluminum is forgiving enough that it won't instantly shatter a solid carbide end mill like steel clamps would.​Sturdy Workholding: The wedge or cam action of side clamps provides immense lateral force, preventing your stock from shifting or vibrating under the heavy loads of high-RPM milling.​Compatibility & Fit​CNC Routers: These are a direct upgrade for desktop machines like the 3018 series. They are light enough not to strain smaller aluminum extrusion beds but rigid enough to handle wood, plastics, and soft metals.​Versatile Mounting: They are designed to adapt seamlessly to standard T-tracks, aluminum grid plates, and perforated spoiler boards. They typically use standard M6 hardware, making them easy to swap into most DIY or hobbyist CNC setups.​Tips for Optimal Use​Use a Backstop: Because side clamps exert lateral (horizontal) force, they work best when pushing your material against a fixed, rigid backstop or squaring fence on the opposite side of the table. This squares up your stock and ensures it cannot slide.​Mind the Material Thickness: Because they are low-profile, ensure your stock is thick enough for the clamp's jaw to get a clean bite without slipping over the top, but thin enough that the clamp doesn't interfere with your lowest Z-axis travels.​Avoid Overtightening on Softer Materials: The mechanical advantage of these clamps can easily mar or crush soft woods, 3D-printed plastics, or soft insulation foam if cranked down too hard. Consider using a thin sacrificial scrap piece of wood between the clamp jaw and your workpiece if surface finish on the edges is critical.

Masterful clamps for small CNCI have a Wizmaker Artisan 01 and these clamps perfectly fit into the spoil board threaded inserts. These were effortless to install, as I just had to remove the T-nut on the bottom of these and use the same screw in the threaded inserts in my spoil board. It is nice to see some standardization on CNCs, especially with clamp screw sizes. I was really happy these fit with no modification to my spoil board. I am also glad to see the orange anodized aluminum color of these clamps match that of my Wizmaker Artisan.What is remarkable with these clamps is the surface of the clamp has a slight decline that makes the top part of the clamp face make the initial contact. This forces the workpiece flat to the spoil board with a downward pressure. The workpiece remains stably clamped flat down to the surface with absolutely no movement in any direction. Repeated clamped to the exact same position by just loosening one of these clamps and leaving the other one anchored in place.These clamps have a impressive low profile and are made of aluminum, so any inadvertent bump by the milling bit would have minimal impact on the bit. The screws are steel, so they still need to be avoided, but they have minimal stick-out. These clamps are totally out of the way when doing large surface milling on most of my projects.The clamps that came with my Wizmaker are the standard steel flat bar type clamps that sit on top of the workpiece. They are in the way and do not allow for workpiece removal and reinsertion to the same point on the table. They can also cause significant damage to CNC milling bits if they are ever struck.I only got two of these Fuzqq CNC clamps, but I'm going to order several more so I can securely hold workpieces from multiple sides, even odd-shaped workpieces. I can also leave a few sides anchored when inserting new workpieces into the exact same position.The only issue I've found is that the threaded inserts on my spoil board do hit spots where some workpieces hit a size that is just outside the adjustable range of these clamps. This also happens on the clamps that came with my CNC. This is fine, as the CNC itself can drill the spoil board for threaded inserts. I'll put in a couple more threaded inserts in the spoil board as I need them. Spoil boards do need to be changed out every so often, so on my next spoil board, I'll adjust the threaded insert spacing, at least on part of the new spoil board, to avoid these fit-type situations. I'd much rather do custom threaded insert layouts for high-quality clamps like these Fuzqq CNC Clamps.I wish that CNC would all come with such well designed clamps. These are really a significant value for the functionality and quality they bring to the CNC projects. I can highly recommend these clamps!

I have been using these aluminum side clamps on my small CNC (similar to a Genmitsu 3018), and they have been a really nice upgrade over the stock hold downs. They fit the T slots in the spoilboard very well and use lateral pressure rather than clamping from the top, which keeps the spindle path much clearer and reduces the risk of a bit crashing into a clamp. The machined aluminum has a professional look and feel, and the bright orange color stands out clearly against the table so they are easy to see while setting up a job.The design is straightforward once you get the hang of it. You slide the T nuts into the slots (or use M6 holes in a spoilboard), position the clamps along the sides of your workpiece, and then tighten the screws to lock the T nuts and apply side pressure. The included hex wrenches make adjustment simple, and the threading is clean so everything tightens smoothly. At roughly three quarters of an inch tall and a little over two inches wide, they stay low profile while still grabbing the stock firmly.On my machine, the only minor hassle is access. I have plexiglass shields along the sides of the bed, so tightening the inner screws with the Allen keys can feel a bit awkward when the workpiece is wide. It would have been nice if both screws used the same size wrench or if there were an option for thumb or wing style tightening in more open setups. That said, once everything is snug, the workpiece stays put and I have had no issues with movement during cuts.Overall, these clamps feel like a high quality, well engineered accessory for a hobby CNC. They are much nicer and more secure than the basic clamps that came with my machine, and the lateral clamping with a low profile is exactly what I want for reducing interference with tooling. As long as you have T slots or M6 mounting holes available, they are an easy recommendation.Pros:High quality machined aluminum construction with a solid, precise feelSide clamping design and low profile reduce risk of hitting clamps with the bitFit standard T slots or M6 spoilboard holes and grip workpieces very securelyBright color and compact size make them easy to see and position on the tableIncludes hex wrenches and hardware for quick setup and adjustmentCons:Uses two different screw locations, so tightening with Allen keys can be a bit awkward in tight spacesWould be even more convenient if both adjustments used a single wrench size or tool free knobs

I've had a Genmitsu ProVer 3018 CNC machine for several years. It's definitely a hobbyists machine, not meant for professional use, but it's great for my limited needs.These clamps fit the T-slots in the bed very well and they do a good job of holding my workpiece in place without getting in the way of the spindle because they grip from the sides rather than the top of the workpiece. It's a cool design. The clamps are made from machined aluminum. They have a professional look and feel.To use them, loosen the screw to each T-nut and loosen the screw to each clamping edge, then slide one clamp into the T-slot on either side of the piece you're clamping. After that tighten the T-nut screws to hold the clamps in place next to the wood and then tighten the screws to to each clamping edge until the part is secure. Test the workpiece to make sure it doesn't move and you're ready to use your CNC.I should note that these clamps require a T-slot or a spoilboard with M6 holes so you have a way to secure the clamps to the bed. The clamps come with two allen wrenches, one for the M6 screws and one for the clamping edge screws. It would have been nicer if they designed it to use only one wrench or maybe wingnuts so you could tighten them by hand but I guess space was a consideration in that design decision.My particular CNC has plexiglass shields to the right and left of the bed and it was a little awkward to tighten the screws using the allen wrenchs so close to the sides. It'll probably be even more challenging for wider workpieces, but not impossible.All that said, I think they're nice clamps, much nicer than the ones that came with my CNC. They look nice, they hold well, plus they're side clamping and low profile so they'll be less likely to make contact with my cutting bits. They're not perfect for all configurations, but I feel they're worth getting. I'm happy with this order.
