Mirka Novastar 5" Grip 89H 120

The Mirka Novastar 5" Grip 89H 120 is a new abrasive disc designed for surface preparation on automotive and industrial machinery. It suits technicians and workshops requiring consistent finish quality on metal, composite or painted panels. The grip backing allows quick changes on compatible backing pads during refinishing workflows. Buyers needing non-grip attachment or different grit ranges should verify compatibility before ordering.

Thermals noise and power draw

As a passive abrasive consumable, the disc generates no operational noise, heat or electrical power draw of its own. Thermal load and acoustic output depend entirely on the sanding machine, workpiece material and operator technique. Dust extraction efficiency and pad condition influence surface temperature during extended use. No power supply or cooling provision is required for the disc itself.

Upgrade path and value

This 120-grit disc replaces worn or clogged abrasives of the same diameter and hole pattern to restore cut rate and finish consistency. The 89-hole configuration improves dust extraction compared to lower-hole-count discs, reducing loading on paint, clear coat and filler. The step up is worthwhile when the current abrasive leaves swirl marks, loads quickly or fails to achieve the target surface profile for the next coating stage.

Questions about this item

How is the Novastar 5" Grip 89H 120 installed, and which step is often missed?

Mount the 5" grip pad onto the machine spindle, then press the 89H abrasive disc firmly until all 120 holes align and lock; the step most often missed is checking that every hole seats evenly before starting the motor.

What maintenance or replacement will the 89H 120 disc need later?

Replace the abrasive disc once the 120-hole pattern shows uneven wear or loading; the grip pad itself lasts through multiple disc changes if kept clean and free of dust buildup.

What limit appears first on the Novastar 5" Grip 89H 120 during sustained use?

Heat buildup in the 89H abrasive layer is the first limit; the 120-hole extraction delays clogging, but prolonged high-speed sanding will still glaze the surface and cut performance.
