Diamabrush 4-1/2 in Blade Kit

This six-piece replaceable blade kit fits a 5 in angle grinder and removes mastic, glue, adhesives, epoxies, thin-set and paint from concrete or steel. It preps bare concrete so new coatings bond securely. The kit suits contractors and DIYers who need fast surface preparation on horizontal or vertical substrates.

Thermals noise and power draw

The blades run on the grinder’s own motor, so heat and noise match the tool you already own. No extra power supply or cooling is required beyond the grinder’s standard operation. Normal use produces typical angle-grinder vibration and dust, managed with the grinder’s guard and your PPE.

Six blades extend job life

Six replacement blades in one pack mean fewer interruptions to swap worn edges during large removal jobs. Compatibility with part numbers FH-45HTSHROUD and 33TP09 confirms fit on common shrouded grinders. The kit contains only the blades; no additional software, adapters or hardware are included.

Questions about this item

How do I fit the 4-1/2 in blades onto a 5 in angle grinder and what step is often missed?

Mount the blades inside the FH-45HTSHROUD shroud first, then secure the shroud to the grinder; the step most users skip is tightening the shroud clamping bolts before the first cut.

Which part wears out first and how often should I swap the six-piece set?

The diamond segments on each blade wear down; replace the full set when segment height drops below 2 mm or cutting speed on mastic and epoxy falls noticeably.

What limit appears first during continuous grinding on concrete or steel?

Heat buildup in the 4-1/2 in blade cores causes segment glazing, so pause every few minutes to let the kit cool and maintain removal rate.
