Quick Answer

Concrete polishing machines mount diamond tooling through a driver plate, and the interface is brand-specific: Husqvarna uses Redi-Lock click-in segments, HTC uses its own shoe and pin pattern, while Lavina, Scanmaskin and Klindex share the universal 3-head plate. Match the pad to the plate — or use an adapter — and the same grinding sequence works across machines.

Concrete Polishing Machine Interfaces

Machine	Interface	Pads / tooling
Husqvarna PG 280 / 400 / 680	Redi-Lock metal-backed	Redi-Lock segments, PCD
HTC 650 / 800 / 950	HTC shoe + adapter plate	HTC trapezoid shoes, resin pads
Lavina G20-G32	Universal 3-head	Trapezoid shoes, resin pad plates
Scanmaskin 32 / 38	Universal 3-head	Trapezoid shoes, PCD
Klindex EXP	Universal 3-head	Trapezoid shoes, discs

Husqvarna: Redi-Lock System

Husqvarna grinders use Redi-Lock — metal-backed diamond segments that snap into the driver head without bolts. Contractors on Husqvarna fleets should buy Redi-Lock-compatible trapezoid grinding discs or PCD segments made to OEM tolerances; compatible aftermarket tooling costs a fraction of the brand price and matches the click-in mounting exactly.

HTC and Lavina: Shoes and Adapters

HTC machines use their own trapezoid shoe with a pin-and-clip interface, while Lavina machines accept the universal 3-head plate. The practical trick for mixed fleets is an HTC-to-universal adapter plate: it lets one set of universal trapezoid shoes run on both HTC and Lavina heads. Resin polishing pads (JOY-RFP-02) mount on a velcro backing plate that bolts to either interface, so the finish steps stay machine-agnostic.

Scanmaskin and Klindex: Universal 3-Head

Scanmaskin and Klindex machines share the universal three-pin driver pattern with Lavina, Edco and most generic planetary grinders. That makes them the easiest machines to supply: one trapezoid shoe range fits all of them. Choose segment shapes by the floor condition — single-rhombus shoes for medium concrete, double-round for general grinding — and swap to resin pads for the final polishing pass.

Which Pads Do You Need for Polished Concrete?

• PCD segments: coating and glue-line removal before grinding (universal or Redi-Lock, per machine).
• Metal bond 16-30 grit: grinding and leveling the concrete surface.
• Metal bond 40-80 grit: transition, removing scratch lines from the coarse pass.
• Resin pads 100-3000 grit: honing and polishing to the target gloss.

Checking Your Machine Before You Buy

• Look at the driver plate: three pins in a triangle = universal; click-in slots = Redi-Lock; pin/clip shoes = HTC.
• Measure the plate size: pads must cover the plate diameter without overhang.
• Confirm the bolt spacing: universal plates use standard M8/M10 spacing; adapters fix the rest.
• Ask the supplier: send a photo of the plate and confirm compatibility before ordering.

Frequently Asked Questions

Q: Are Husqvarna pads compatible with Scanmaskin machines?

A: No. Husqvarna uses Redi-Lock and Scanmaskin uses the universal 3-head plate. Use a Redi-Lock-to-universal adapter or buy per-interface tooling.

Q: Can I use the same resin pads on HTC and Lavina machines?

A: Yes, with the right backing plate. Resin pads mount on a velcro backing plate; choose the plate that matches your machine interface and the pads are universal.

Q: What machine interface is easiest to supply?

A: The universal 3-head plate (Lavina, Scanmaskin, Klindex, Edco). One trapezoid shoe range covers the widest fleet with the smallest inventory.

Q: Do I need separate tooling for PCD coating removal?

A: Yes, PCD segments are job-specific, but they come in both Redi-Lock and universal versions — pick the one that matches your machine head.

Conclusion

Matching pads to your concrete polishing machine is about the driver plate, not the brand badge. Standardize on the universal 3-head interface where you can, keep PCD for coating jobs and finish with resin pads. JOY TECH's resin polishing pads and trapezoid tooling cover every major interface — send us a photo of your plate and we will confirm the right set before you order.
