120 Grit Bulldog Gold Disc
The Mirka 23-608-120 is a three-inch grip disc built for finishing and heavy stock removal. Its 120 grit rating suits surface preparation tasks in automotive and industrial workshops. The semi-open coating reduces loading during extended sanding sessions. Professionals who need consistent cut rates on paint, primer or composite substrates will find it reliable.
Semi-open coating with stearate
A special stearate treatment actively resists clogging and pill formation across the abrasive surface. This keeps the cutting edges exposed so material removal stays steady rather than dropping off as dust accumulates. Less loading means fewer disc changes and a more uniform finish on each panel. Heat buildup at the workpiece is also moderated by the open structure.
Grip backing for quick changes
The hook-and-loop style backing locks onto compatible backing pads without tools. Operators can swap grits or replace worn discs in seconds, keeping downtime low on multi-stage jobs. The three-inch diameter fits standard pneumatic and electric random-orbital sanders used in body shops. No adhesive residue is left on the pad when the disc is removed.

Questions about this item
How do I attach the 23-608-120 disc to my sander without it slipping?
Press the grip backing firmly onto a clean hook-and-loop pad, aligning the centre hole; the semi-open coating and stearate layer reduce clogging so the disc stays flat during use.
When should I replace the 120 grit disc during a refinishing job?
Change it once the gold abrasive dulls or the stearate coating wears off, as pill forming returns and stock removal drops noticeably.
What limits continuous sanding with the Bulldog Gold disc before performance falls?
Heat buildup in the semi-open coating is the first limit; prolonged heavy stock removal softens the stearate and cuts abrasive life.
