HTC GL 450 Diamond Floor Grinder

A planetary grinder for both concrete grinding and floor prep

HTC Greyline™ 450 is a single-phase, planetary grinder with three grinding heads and a counter-rotating grinding wheel for a stabile grinding without lateral forces. It works equally well for concrete grinding and floor prep as it does for grinding/sanding of wooden floors. The machine is divisible for easy transport.

  • Easy Grinding
    Literally means easy grinding. Select and attach your tools, plug the machine to the wall & start grinding.
  • Easy tool choice
    Three standard tools in different grit sizes for removal of coatings and leveling of concrete are all the tools needed, it can’t be easier.

  • Floating Cover
    HTC GL™ 450 Comes with a floating cover. The floating cover simplifies handling of the machine and creates a better dust absorption. No need for a separate splash guard.

  • Robust chassis

    The robust and sturdy chassis makes the machines perfectly balanced which is important when grinding but also simplifies machine handling for tools change etc.

  • Good working environment
    Machines are perfectly balanced during grinding with vibration levels much lower than the threshold values. Sound levels are very low and grinding is more or less dust free.
