The CO-FREEZE SG INOX is a POLIFAN flap disc with ultra-cool grinding and has been specifically developed for use with stainless steel and nickel-based alloys (e.g. Inconel and Hastelloy). Its particular strengths are surface grinding and working on weld seams, and it more than stacks up against the well-known PFERD product, the  POLIFAN CO FREEZE SGP STRONG INOX .

Optimum results with high economic efficiency

Due to the ceramic oxide grain CO with active grinding, cooling special coating (FREEZE), heat build-up in the workpiece is significantly reduced. There is no heat discolouration, thanks to the low thermal load. This means reworking is no longer required and thereby helps the  POLIFAN CO-FREEZE SG INOX deliver significant added value.

The ceramic oxide grain itself has an aggressive stock removal rate and therefore produces fast work progress. Thanks to its ultra-cool grinding, the chips that are produced are not glowing and flying sparks are reduced to a minimum. As a result, the workpiece itself, as well as surrounding stainless steel components, are not affected.

All the benefits at a glance:

• Low heat build-up thanks to FREEZE coating.
• Fast work progress and high economic efficiency.
• Maximum aggressiveness over the entire tool life.
• Fewer tool changes due to the outstanding tool life.
• Flying sparks reduced to a minimum.

Do not mistake the following

The flaps on the POLIFAN CO-FREEZE SG INOX will already begin to exhibit an unusual wear pattern after a short time during the first use. A shiny cooling film formed by the highly effective fillers becomes visible. This  cooling film provides the basis for ultra-cool grinding but which, in combination with the reduction in flying sparks, must not be mistaken for tool vitrification.
