Shrinking Discs Archives - Metal Man Tools https://metalmantools.com.au/product-category/shrinking-discs/ Shaping a better Australia Thu, 16 Apr 2026 22:38:17 +0000 en-AU hourly 1 Shrinking Disc Set https://metalmantools.com.au/product/shrinking-disc-set/ Wed, 30 Jan 2019 06:10:13 +0000 http://metalmantools-com-au.aliases121.com/?post_type=product&p=1752 These Shrinking Discs work on aluminium and steel and the secret to them is that they create heat through friction when spinning and touching the metal. When the area is cooled by either a squirt of soapy water or compressed air the heated area cools and shrinks.

Included discs are in 2 sizes, the larger 230mm one is suitable for use on a 7" grinder or sander and the smaller 125mm one is suitable for 5" grinders. This kit includes the rubber sanding disc that you require to support the disc and also the tapered nut to attach the disc to your grinder or buff.

]]> How It Works:
  • The disc is spun against the metal surface at moderate pressure.
  • Friction creates localized heat on the high (stretched) areas of the panel.
  • The hot spots are quickly cooled with a wet rag or spray bottle.
  • The rapid cooling causes the metal to contract, shrinking the stretched areas.

Repeated cycles of heating and cooling allow for precise control over the metal’s shape.

Key Features & Benefits:
  • Provides controlled metal shrinking without thinning or damaging the panel.
  • Produces a smooth finish, since it only affects high spots.
  • Safer and gentler than flame shrinking.
  • Ideal for panel straightening, weld repair, and finishing.
