Exactly as advertised. Works to insert and remove carbide tooling from various HSK holders (Haimer, ISCAR, and Lyndex Nikken shrink fit holders). I got the "H5000S" version (all manual). I asked for no plug and just attached my own NEMA 6-30P. The height positioning of the head is important for proper heating. You may need to try a few different heights to figure out what is best for your specific toolholder.
I haven't tried this with HSS tools yet (HSS doesn't work as well with shrink fit), but it certainly works for carbide. I've tried sizes from 1/8" to 1/2" so far. I've only had the machine for a day or two, but it seems well-built. It is basic, but I have no complaints.
