MPA Hannover ISO 9001 80 m/s 8,600 rpm Test according to the oSa method
When you need a 180 mm cutting disc
A 180 mm disc goes on 180 mm grinders of about 2000 W when a 125 mm disc does not reach: large-diameter pipes, heavy profiles, rebar cages, rails. The cutting depth of a new disc is about 40–45 mm, a third more than 125 mm, while the tool is lighter and handier than a 230 mm one.
NovoAbrasive makes 180 mm discs on Davide Maternini (Italy) equipment with grain from Saint-Gobain and Imerys; every batch is tested by the oSa method, the products are MPA Hannover certified and comply with EN 12413.
How to choose the thickness of a 180 mm cutting disc
| Thickness | Application | Advantages | For whom |
|---|---|---|---|
| 1.6 mm | Pipes, thin-walled profiles, sheet metal | Fast cut with minimum kerf width | Fitters, workshops |
| 2.0 mm | Pipes and profiles of medium thickness | Balance of speed and resource | Universal choice |
| 2.5 mm | Rebar, heavy profiles, stone | Longer life, resistance to tilting | Builders |
| 3.0 mm | Thick metal, stone, concrete | Maximum resource | Heavy work |
| 4.0 mm | Heavy workpieces, castings, rough metal cutting | Maximum strength | Industrial conditions |
Rule: a thin disc cuts faster and cleaner, a thick one lasts longer and holds a straight line better in heavy metal. For daily work on pipes and profiles 1.6–2.0 mm is optimal.
Metal or stone: abrasive and series
For metal— aluminium oxide (Standard, Profi series) and ceramic aluminium oxide (Extreme) for structural steel, pipes, rebar, profiles; discs marked INOX contain no iron or sulphur and are safe for stainless steel.
For stone— silicon carbide (SiC) for concrete, brick, stone, granite and tile: the hard sharp grain cuts mineral materials on which corundum quickly dulls.
Series: Standard (NovoAbrasive Standard, Hetman) — household and occasional work; Profi (NovoAbrasive Profi, WellCut) — daily professional work, MPA Hannover; Extreme — industrial conditions with extended life.

Tool compatibility
180 mm cutting discs fit all 180 mm angle grinders with a 22.23 mm bore, for example Bosch GWS 22-180 or Makita GA7020. The maximum tool speed must not exceed 8,600 rpm.
A 180 mm disc may be fitted on a 230 mm grinder if the guard and flanges match: its speed is below the disc limit, but the cutting depth will be smaller. Fitting a 180 mm disc on a 125 mm grinder is prohibited.

FAQ
Frequently asked questions
What is the cutting depth of a 180 mm disc?
About 40–45 mm with a new disc — it depends on the flange diameter and the grinder guard. As the disc wears the depth decreases, so for pipes over 80 mm take 230 mm.
Can a 180 mm disc be fitted on a 230 mm grinder?
Yes, if the guard and flanges fit: the speed of a 230 mm grinder (up to 6,600 rpm) is below the limit for a 180 mm disc (8,600 rpm). The reverse — a 230 mm disc on a 180 mm grinder — is prohibited.
Which thickness for pipes and rebar?
For pipes and profiles — 1.6–2.0 mm: a fast cut with minimal sparks. For rebar, rails and heavy profiles — 2.5–3.0 mm: the disc does not tilt and lasts longer.
Are there 180 mm discs for stone and concrete?
Yes, silicon carbide (SiC) discs for concrete, brick, stone and tile. For frequent concrete cutting a 180 mm diamond blade is more economical — it does not shrink in diameter and lasts many times longer.
What is the maximum speed for a 180 mm disc?
No more than 8,600 rpm, which corresponds to a rim speed of 80 m/s. This value is printed on the label of every disc; check it against the grinder speed before mounting.
