Concrete surface grinders versus ordinary angle grinders

[Stephen Tashiro]

As far as hand held tools go, what's the difference between a "concrete surface grinder" versus an ordinary angle grinder with a diamond surfacing disk and dust shroud on it? Do the surface grinders have a lower RPM?

I would guess water hookup. That is about it for my little 4.5" handheld concrete/tile saw

In the predominant terminology on the internet, the "concrete surface grinders" ( https://www.amazon.com/gp/product/B07F32BL4B?pf_rd_r=7TGBKMAP2JPDGX4YXETD&pf_rd_p=5ae2c7f8-e0c6-4f35-9071-dc3240e894a8&pd_rd_r=39990719-5987-42f5-b758-d4b81b215588&pd_rd_w=BRUmN&pd_rd_wg=9mPHJ&ref_=pd_gw_unk ) don't feature a water hookup. It's the "concrete polishers" (https://www.ediamondtools.com/products/5-variable-speed-wet-polisher?variant=5168497688606&utm_source=bing&utm_medium=cpc&utm_campaign=**LP%20-%20Shop%20-%20Handheld%20Grinding%20-%20Multiplier%201&utm_term=4582214719575640&utm_content=VSP0500RDP5512481530R5BP%20%7C%205%22% 20Variable%20Speed%20Wet%20Polisher%20Bundle%20wit h%20Dry%20Polishing%20pads%20for%20Granite%20Marbl e%20and%20other%20Stone%20Surfaces%20%7C%20%24249. 99 ) that have the water.
