HTC - The Innovators!

Easy Grinding
HTC Greyline™ 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.

Divisible for easy transport
All floor grinders in the HTC Greyline™ series are divisible which make the grinders easy to transport.

Floating Cover HTC Greyline™
All grinders in the HTC Greyline™ series come 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.

Adjustable chassis and handle
The floor grinder’s chassis and handle can easily be adjusted to fit your preferred working position. HTC recognize the value of good ergonomics.

EZchange™

Good working environment
