Cutting Discs — Ronix Saudi Arabia

Ronix cutting discs are engineered for Saudi jobsite conditions — abrasive cutting wheels for steel and stainless, diamond discs for concrete and tile, flap discs for surface prep. All Ronix discs comply with EN 12413 safety standards (reinforced with fiberglass mesh for burst protection at 80-100 m/s peripheral speeds). Sizes range from 100mm for compact grinders up to 350mm for cut-off saws.

Best Applications

  • Cutting structural steel, rebar, and conduit on construction sites
  • Stainless-steel cutting with non-contaminating discs (no iron/sulfur fillers)
  • Cutting ceramic tile, porcelain, and natural stone with diamond rim discs
  • Concrete cutting for cable trays and pipe channels (with segmented diamond)
  • Surface preparation with flap discs (60/80/120 grit) for weld grinding

Buying Guide — What to Look For

Disc type
Abrasive cutting (steel, stainless), diamond cutting (concrete, tile, stone), flap discs (grinding/finishing), wire cup brushes (rust removal).
Disc diameter
Match the grinder — 115mm for 115mm grinders, 230mm for 230mm grinders. Don't fit a larger disc on a smaller grinder.
Thickness
1.0-1.6mm for fast steel cutting (less material loss), 2.0-3.0mm for heavy cutting and notching, 6mm+ for grinding discs.
Grit / segment type
60 grit for fast steel removal, 120 grit for finer finish. Continuous-rim diamond for tile, segmented diamond for concrete.
Max RPM rating
Must equal or exceed your grinder's no-load RPM. 115mm discs typically rated to 12,000-13,000 RPM.
★ SAUDI MARKET NOTE

Steel-cutting discs degrade faster in humid coastal jobsites (Jeddah, Dammam) due to ambient moisture absorption. Buy in smaller quantities, store sealed in dry conditions, rotate stock.

Frequently Asked Questions

Can I use a steel-cutting disc on stainless steel?
No — standard ferrous cutting discs leave iron deposits that cause rust contamination on stainless. Use dedicated INOX/stainless cutting discs (no iron/sulfur fillers).
Diamond disc vs abrasive disc for concrete?
Diamond is the only practical choice for concrete and tile — abrasive discs wear out in seconds on hard masonry. Diamond discs cost more upfront but last 20-50× longer on these materials.
Thin discs (1mm) vs thick discs (3mm) for steel?
1mm discs cut faster with less material loss — ideal for thin profiles, conduit, and rebar. 3mm discs handle heavier work, large structural sections, and last longer.
How do I know when to replace a cutting disc?
Replace when the disc is worn down past the safety marking, when it loads up (clogs), or shows any chipping/cracking at the rim. Never use a damaged disc.
Are these compatible with non-Ronix grinders?
Yes — discs are sized by diameter and bore (typically 22.2mm), not by tool brand. Any 115mm/22.2mm disc fits any 115mm angle grinder.
