The 84 Engineering SOSGA is a compact surface grinding attachment designed for use with Shop Mate 48”, Shop Master 72” or Gibson 72” belt grinders, using a SOSGA tooling arm to suit your model.

Details

The SOSGA comprises a magnetic surface grinder chuck with a CNC machined aluminium billet body, twenty high strength neodymium magnets, an easy-to-clean stainless steel chuck face, and an adjustable safety stop at the base of the chuck. The tool is designed to achieve grind accuracy of <50 micron, making it suitable for a variety of precision applications.

The UHMWPE internal wear components ensure tool longevity, smooth operation, and extreme rigidity. High accuracy ball-bearing linear rails are used for the sliding mechanism, and the 6061 aluminium contact wheel is coated in a highly durable 90 Shore A polyurethane rubber compound that provides minimal surface distortion whilst having enough flexibility to achieve a great surface finish.

The tool is powder coated for durability and features zinc plated steel components, a spark guard, and a stainless steel chuck. Setting taper angle is achievable simply by using shims, and depth adjustment is made using the knurled aluminium knob.

The SOSGA includes the Strap-On Surface Grinder Attachment and sliding linear rail. The Standard Dial Gauge is sold separately.

Easy and it works
Color: Silver, Size: Compact
It works! It doesn’t have different speed settings, and you have to make sure you have the right kind of milk, but so far it’s been great and easy to use.

Simple upgrade that actually feels worth it
Color: Black, Size: normal
I replaced a cheap milk frother I had from Walmart with this one, and it’s definitely an upgrade. Right out of the box it just feels a bit nicer and more solid, not flimsy like the other one. It’s also noticeably more powerful. It froths milk really quickly and does what it’s supposed to without any effort. I did notice it only has one ring on the whisk compared to the two on my old one, but I honestly don’t notice any difference in how it works. Only small thing was getting the batteries in, which was a little tighter than I expected. Not a big deal, just took a second. Overall, it just works well and feels worth the price. I’ve only had it for a short time, but so far I’m happy with it and hoping it holds up.

Great frother at a good price
Color: Black, Size: normal
Works really well and priced appropriately. Produces rich froth with minimal effort and works MUCH better than other much higher priced frothers. Highly recommended. I hope it lasts a good long time.

Perfect for protein shakes and coffee - one warning about getting it wet
Color: Black, Size: normal
Bought this to replace a similar handheld whisk I had been using for protein shakes and stirring extras into my morning coffee. At this price point I was not expecting much, and it has done exactly what I need - with one warning I will get to. I use this almost every morning. Two jobs: mixing a scoop of whey protein into water or milk so it actually dissolves (no clumps stuck to the side of the shaker), and stirring pre-workout powder or a flavor additive into my coffee. This is not a blender and I do not treat it like one. For small-volume mixing of powders into liquid, it is the right tool. WHAT WORKS - It does not over-froth or whip air into the drink. Some handheld whisks turn a protein shake into a foam mess. This one keeps the liquid liquid - it just dissolves the powder. That is the main reason I came back to this category. - No splashing, even with the cup near the brim. I can stir a nearly-full coffee mug without flicking liquid onto the counter. The previous one I owned could not do this. - One button. Runs as long as I hold it. A typical protein shake or coffee mix takes under ten seconds. - Easy to hand-wash. Rinse the whisk end, wipe the handle, back in the drawer. WHAT DOES NOT (the warning) - You cannot throw the whole thing in the sink with the rest of the dishes. The handle is not waterproof. We made this mistake exactly once - it got soaked, never worked again. At this price the loss was not a big deal, but it is the one thing I wish the listing made more obvious. Hand-clean the whisk end only, keep the handle dry. - Battery-powered. Replace the batteries when it starts feeling slow rather than waiting for it to fully die mid-shake. WHO IT IS FOR If you need a small-volume mixer for protein powder, coffee, hot chocolate, pre-workout, or anything where you are dissolving a powder into a single cup or shaker, this is the tool. If you want to blend smoothies or actually break down ingredients, buy a real immersion blender instead. Five stars. The wet-handle failure was my mistake, not the product's. Doing its job every morning - would buy again.

Color: Black, Size: normal
Works wonderfully if the liquid you’re blending has no viscosity, but it slows down brutally if given any kind of resistance. It’s small and lightweight and very easy to use. Works for my bloom, but it does not work very well for my protein shakes.
