August Rüggeberg develops, produces and markets tools for surface finishing and cutting materials under the brand name PFERD ("PFERD" is German for "Horse"). The company offers the best combination of quality tools, drives and individual advice that customers need to find the best solution for their surface finishing tasks and for cutting materials. PFERD has introduced a new patented Polifan®-Strong construction shape that opens up a completely new dimension in grinding work. Alongside the version SGP Zirkon-Strong, PFERD now also offers this high-performance tool as the SGP Costrong- Freeze version for working materials with low heat conducting properties such as stainless steel (INOX).

Superb features give great benefit as far as performance is concerned:

• Quick grinding due to consistent highly abrasive quality right up to the last abrasive grain, and
• Maximum economic efficiency due to increased performance per time unit and less wear on discs.
• The PFERD high-performance tool in the SGP Zirkon-Strong version is highly suitable for demanding grinding work with particularly high stock removal performance. Features include:
• Largest possible stock removal
• Extremely long tool life
• Maximum economic efficiency due to fewer tool changes and set-up times, and
• Optimum use of high-performance tool drive.

Recommendation for Use

• Grit size 36 is optimally suitable for high stock removal, e.g., for weld dressing, and
• Grit size 50 is optimally suitable for work on edges.

With the innovation Polifan®-Strong Freeze, PFERD is offering a flap disc with cool grinding unparalleled anywhere in the world. This is particularly advantageous when working materials with poor heat-conducting properties such as stainless steel (INOX).

Special Features

The innovative design of the ceramic grit abrasive reduces sparks to a minimum. This means that damage to stainless steel workpieces caused by glowing sparks flying around is almost excluded. The very first time the Polifan®-Strong Freeze, is used, the flap reveal an unusual wear pattern even after only a very few seconds. The highly effective fillers form a shining cooling film on the flap. This is the basis for cooling, aggressiveness and tool life previously not achieved. The shape and colour of the chips produced with Polifan®-Strong Freeze, are proof of the extremely low temperatures during the grinding process.

Performance Values for Surface Grinding on Stainless Steel (INOX)

Surface temperature reduced by 30 %

The surface temperature is reduced by 30 % during the grinding process. No heat accumulation, no deformation, no thermal damage to the joints in the workpiece.

Aggressiveness and tool life increased by 50 %

Tool life and aggressiveness for surface grinding and for the levelling of welds are about 50 % higher than those of conventional flap discs. No glazing, constant use right down to the last grit.

Grinding comfortably and ergonomically

PFERD Ergonomics recommends the patented flap discs Polifan®-Strong Freeze, as the innovative tool solution for maximum service life with minimum dust development and significantly reduced vibrations. The unusually high abrasive effect means work can be carried out at a very low grinding pressure without too much physical effort being required. High-performance tool in the SGP CO-Strong- Freeze version for the most demanding of grinding tasks. The innovative abrasive with ceramic grit guarantees ultra-cool grinding on materials with poor heat-conducting properties. Maximum material removal and outstanding service life.
