Q1: How do I choose the right bond (Hard/Medium/Soft)?

A: Soft Bond: Use for Hard Concrete. The bond wears away faster to expose new diamonds. Hard Bond: Use for Soft/Abrasive Concrete. The bond holds the diamonds longer to prevent premature wear. Medium Bond: For general purpose concrete (standard hardness).

Q2: What is 30/40 grit used for?

A: 30/40 grit is the standard "First Cut" or "Second Cut" for most floors. It is used to open the concrete pores, remove light coatings/glues, and level minor unevenness.

Q3: Will these fit my Husqvarna or HTC machine?

A: These are standard trapezium shoes. If your machine uses a Magnetic Adapter Plate (which most do nowadays), these will fit. For direct slide-on compatibility (Redi-lock or EZ-change), please check our specific compatible models.

Q4: Is "2 Bar" better than "1 Bar"?

A: 2 Bar lasts longer and leaves a smoother scratch pattern, making it better for general grinding. 1 Bar is more aggressive (higher pressure) and is better for removing thick coatings or very hard concrete, but wears out faster.
