needle scalers

[mikehaugen]

I use mine (inline style) to remove slag from corner welds that can't be reached with a wire wheel on a grinder. It does a good job and there are no consumables to buy, wire wheels are getting spendy, plus it does peen the weld. It also works good for removing dried on grass build up under my mower deck. Handy tool for me I'd say get one.

This is what prompted me to consider this, many times I just can't get a wire wheel into a corner and haven't yet come up with a better way to get it out. Thanks everyone for the replies, you have all done a fine job of justifying another tool purchase

I have one of the old HF scaler attachments for an air hammer, haven't seen them offered for several years now. As stated, the air hammer can be had for $8 on sale so it has one dedicated to it. They do work great for cleaning cement off metal, I used mine a lot cleaning out wheelbarrows when I did maintenance for a fence company. They didn't have any way to flush out the barrows on site and would soon gain 30 or 40 pounds, about half a minute would clean them out and do a lot less damage than the mouth-breathers beating them with sledge hammers.

Yeah, I used to work at a concrete plant. They made quickrete, spec-mix, and c-cure. The spec-mix usually came in 3000# bags and we would supply the bricklayers with a "silo" to use. The silo was basically a big cone shaped hopper that could be raised in the air and had drop down legs. They could then park their mixer under it and dump it in. These were loaner units and when the job was done they would come back to the plant and there was a dedicated guy and all he would do all day is chisel off all of the mortar residue from the moving parts and make sure everything worked. He used the heck out of that needle scaler and it worked well.

I use my air hammer to remove slag from in corners if I have a lot of it, but normally just use a chipping hammer. I have thought several times of getting a needle scaler as it would work better than the air hammer for slag and rust and scale removal in corners where a grinder cant get. Maybe next time HF has a sale on one, I will jump on it.
