Choosing Redi-Lock grinding pads comes down to matching the mounting system, pad size, and bond to your grinder model and the job. Redi-Lock is Husqvarna’s quick-change magnetic system: pads snap onto a Redi-Lock adapter plate fitted to the grinder head. Check that your machine takes Redi-Lock tooling (Husqvarna PG-series and many aftermarket machines accept adapters), confirm the pad diameter matches your head (typically 3''/75mm per segment position), then select tooling by task — PCD for coating removal, metal-bond 30/40–80/120 for grinding, resin for polishing. If in doubt, use a universal 3'' Velcro Backer Pad or Redi-Lock compatible disc and verify fit before buying in bulk.
| Job | Recommended Redi-Lock Tooling | Example |
|---|---|---|
| Epoxy / coating removal | PCD discs | Redi Lock PCD Disc for Epoxy |
| Grinding / leveling | Metal-bond 30/40–80/120 | Metal-bond trapezoid discs |
| Honing / polishing | Resin pads on backer | Resin polishing pads |
| Bush hammering | Bush hammer plate | Husqvarna bush hammer plate |
Quick-change systems vary between brands and revisions. Before ordering a full set, buy 2–4 pads, mount them, run a 5-minute test on scrap concrete, and confirm: the pads lock in without wobble, the machine runs balanced, and the cutting rate meets expectations. This one step prevents a whole pallet of incompatible tooling.
A: Only if your machine has a Redi-Lock adapter plate. HTC uses its own quick-change system and Scanmaskin uses bolt-on or its own holder. Buy the adapter made for your brand, or choose tooling in your machine’s native system.
A: Redi-Lock is a magnetic/mechanical quick-change system for aggressive grinding tooling; Velcro is a hook-and-loop mount used mainly for resin polishing pads. Many machines use Redi-Lock for grinding and a Velcro backer for polishing.
A> Not directly — Redi-Lock is a floor-grinder mounting system. For angle grinders use cup wheels or a Velcro backer pad with discs.
A> The same rules apply: segment height under ~2mm, slow cutting, vibration, or visible cracks. PCD discs are worn when the teeth are flush with the matrix.
A> Mostly yes for Husqvarna’s own system, but third-party "Redi-Lock compatible" pads can vary in magnet strength and lock ring tolerance. Test a sample from your supplier before bulk orders.
The right Redi-Lock pad is chosen in four steps: confirm your machine accepts the system, match pad size and mount, pick tooling by job (PCD for coatings, metal-bond for grinding, resin for polishing), and test a small set before bulk buying.
