  Stiff Fibre backing provides durability and tear resistance
  Suitable for high-speed operation up to 30000 rpm
  Quick-change Roloc attachment enables fast disc swaps
  Maintains Sharp cutting points for prolonged disc life

Applications

• Used for weld removal on stainless-steel assemblies
  Suitable for bevel preparation in robotic welding cells
  Ideal for surface blending in electrical enclosure fabrication
  Can be used for medium-pressure metal deburring in automation lines
  Suitable for non-ferrous metal finishing in electronic component manufacture

What hole size is required for mounting on compatible adapters?

The centre aperture measures 22mm to fit standard quick-change adapters.

How is heat management achieved during grinding of sensitive alloys?

A built-in grinding aid lowers operating temperatures and helps prevent stress cracks and discolouration on heat-sensitive metals.

What abrasive mineral is used and how does it affect cutting performance?

The abrasive uses re-engineered precision-shaped ceramic grain with curved facets that retain Sharp points to sustain fast cutting with reduced user pressure.

What pack quantity and colour coding should I expect for stock control?

The product is supplied in packs of 50 and is identified by a purple colour.
