## Description

======================= DESCRIPTION ====================== ​PRODUCT NAME: High Quality Vacuum Brazed Diamond Grinding Disc QUANTITY: 1pc only SPECIFICATION: Diameter 115mm (4.5"), Bore 22.23mm (7/8"), ,Diamond grit #30/40 FEATURE: Dry or Wet working Multi-purpose for granite marble natural stone ceramic and even steel grinding #30/40 Coarse high quality Diamond grain ensure aggressive working performance Vacuum Brazed Technology provide faster grinding Speed and longer working life Easy to operate and safer for operater -------------------------------------------END---------------------------------------------

Review: Used this disk for roughly three months or so intentionally trying to kill it, its lost some effectiveness in areas where its been heavily used but still works very well with a bit of pressure and is basically new in areas of the disk that haven't seen as much use. I'm an Ironworker and it has been invaluable as a tool, it rips through galvanization on iron without putting pits in metal, can be used to make cuts if you're in a bind just have to go slow, and can reliable grind down welds flush with existing metal. It is kind of heavy and thick so the only worry long term is it damaging your grinder or wearing it out, but with that it dose not require hardly any pressure at all to do its job so your tool will never really be bogged down by it so im not sure on that yet, ill update this if I can in the future. Pretty solid would recommend for the job scope of Ironworking.
Review: Extraordinaire outil pour nettoyer ou rectifier le métal neuf ou soudé ou rouillé dans un temps record comparé à toute autre meule abrasive WOW ! Merci vous me faites gagner du temps à chaque usage !

Oh, does that thing grind! Scary if put in the hands of someone you don't trust, but useful for quicly grinding off imperfections on mild steel (haven't tried other steels, yet). It grinds faster than regular grinding stones of the same size, given the grit, and the rounded shape lets you really gently grind off small details. Will you have to come back with another wheel for a smoother finich if aestyhetics are important? Yeah, but think of the time you'd waste compared to this if you only had a regular stone! No match!
