OVERVIEW

Long-Lasting Grinding Performance for Professional Fabricators

Stop wasting time changing out worn-down discs halfway through the job. The Pferd 60650 POLIFAN Flap Disc is built for welders who need tools that last as long as they do. Featuring a 'Thick' build with 40% more abrasive cloth than standard economy discs, this 7-inch flap disc keeps grinding long after others have quit. It is the perfect solution for heavy fabrication shops processing large volumes of steel or stainless steel.

The Type 29 conical shape is a favorite among pipe welders and fabricators for its ability to attack welds at a comfortable angle. Whether you are beveling plates, grinding down heavy weld seams, or blending corners, the angled flaps provide aggressive bite without sacrificing control. The 80 grit Zirconia face leaves a smooth, clean finish that is often paint-ready, saving you from having to switch to a sanding pad for final prep.

Pferd's premium Zirconia Alumina grain runs cooler than traditional aluminum oxide, which is critical when working with stainless steel to avoid heat discoloration. The cushioned feel of the flaps reduces vibration, fighting operator fatigue during long shifts. Equip your 7-inch grinder with the Pferd 60650 and experience the difference that high-density, premium abrasives make in your daily production.

FAQ

Type 27 discs are flat and best for blending on flat surfaces at shallow angles (0-15 degrees). Type 29 discs, like this Pferd 60650, are conical (angled) and are better suited for aggressive grinding, contour work, and edge grinding at steeper angles (15-25 degrees).

While Zirconia can grind aluminum, it is not specifically designed for it and may 'load' or clog up with soft aluminum material. For aluminum, it is better to use a flap disc with a specialized coating or grain designed to prevent loading.

In this context, 'Thick' refers to the density and amount of abrasive flaps layered on the disc. This model contains approximately 40% more abrasive material than standard discs, providing a much longer service life.

80 grit is typically considered a medium-to-fine grit for metalworking. For removing heavy welds rapidly, a coarser grit like 40 or 60 is usually faster. 80 grit is better for blending the weld into the base metal and preparing the surface for finishing.

Always check the label on the actual disc for safety, but generally, 7-inch flap discs are rated for a maximum speed of around 8,600 RPM. Never exceed the RPM rating of the accessory.

No, this flap disc comes with a built-in fiberglass backing plate. It mounts directly to the angle grinder using the standard flange nut or a quick-change nut.
