Cool stainless steel grinding with Pferd

Practical benefits

Cool grinding on stainless: Active grinding additives reduce heat buildup during use, helping you prevent discoloration on heat-sensitive stainless steel.
Self-sharpening ceramic grain: The ceramic abrasive continuously exposes fresh cutting edges, giving you consistently high stock removal throughout its service life.
Flexible contour adaptation: The radial 165X50 mm flap design flexes smoothly to let you follow complex curves and irregular workpiece contours.

In a nutshell

The right choise for

With the Pferd fr 16550/25,4 co-cool 80 flap wheel, you grind stainless steel and heat-sensitive metals without the risk of thermal discoloration or heat tint. Active grinding additives in the coating ensure effective cooling, while the self-sharpening ceramic grain delivers consistently high stock removal throughout its service life. The flexible radial 165X50 mm flap design adapts smoothly to contours and curved workpieces. Featuring a 25.4 mm bore and grit 80, this wheel allows you to deburr, finish, and prepare weld seams on stationary bench grinders or straight grinders at speeds up to 5.700 RPM.

Product description

PFERD Flap grinding wheel FR dia. 165x50 mm centre hole dia. 25.4 mm CO-COOL80 for cool grinding on stainless steel

Characteristics

On unmounted flap wheels, the flaps made of coated abrasive are arranged radially around the tool axis in a fan-type structure
Their flexibility enables them to adapt perfectly to the contours of the workpiece
The abrasive grain is embedded in the sturdy, flexible cloth backing material by means of a resinoid bond
In ISO 5429, unmounted flap wheels are designated as ""flap wheels""
For aggressive grinding with maximum stock removal rate on hard materials which do not conduct heat well
Consistently high performance due to self-sharpening ceramic oxide grain
Active grinding additives in the coating substantially improve the stock removal rate, prevent clogging and result in cooler grinding

Advantages:

Highly flexible, enabling optimal adjustment to the contour.
Consistently high stock removal rate over the entire tool life as new, aggressive abrasive is constantly exposed.
Can be used face-down very close to edges and in corners thanks to special clamping system.
