You can get a better deal at Amazon:

I've used a lot of these and they compare favorably to the HF ones, in fact they might be the same thing.

 

 

i've been using those purple Amazon grinder sponge looking discs with my  90 degree angle grinder - work great to clean rust -- i prefer to avoid Amazon if possible.... but had not been able to find them elsewhere - HD etc -- I do use the mini Ingersol Rand air grinder with 1 or 2 inch discs for tight spaces........... but the Scaler noted in this thread is wonderful for certain rust applications  - especially in tight seams and cracks or really heavy chunky rust -- Scaler is especially useful in 90 degree corners ..... I use whatever rust removal tool works best,---- Here are some photos of plow blade rehab projects - just did rust removal with grinders/scaler - then hand sand paper, then soap and water then primed -- doing final red paint today in warm sun - also attached is plow i finished last months project - I have had sand blasting done for my mowers, but the plows just need the spot grinding then prime and paint.

HF Needle Scaler

Does that scaler really consume 29 gallons of air per minute ?

 

Edit:

 

Oh, now I see… at least a 29 gallon tank…

both my scaler and my mini Ingersol Rand grinder use lots of air - i suggest you check the air requirments spec on the tool ........as well as the performance spec on the compressor............. I have 5.5 hp, 30 gallon with 6.4 cfm and even that runs pretty continously depending on the demand and usage

Yup, the L/D (length to diameter) ratio is high, probably 6 to 1 or greater, as it needs to be on this application, but - a great place for it to rust up solid. Any way to drill and cross drill for a grease fitting ?? Just a thought.

If you fit a grease “zerk”, cut a shallow groove around the shaft level with the zerk. Then with a grinder, (cutting disc), cut a groove along the shaft almost to the ends. This will become a‘reservoir’ for the grease and ensure when the shaft is turned, grease will spread over more of the bore, you could cut a couple of shallow longitudinal grooves to ensure the whole area gets greased!
