62052 - Pferd POLIFAN 4.5-Inch Zirconia Flap Disc 40 Grit Type 29

Industrial Grade Stainless Steel Grinding

The Pferd 62052 POLIFAN Flap Disc is engineered for professional metalworkers who demand consistency and performance when working with stainless steel. As part of the POLIFAN line, this abrasive tool integrates high-quality Zirconia Alumina grain with a durable backing system, ensuring that it stands up to the rigors of heavy industrial use. The 40 grit composition is specifically selected for rapid stock removal, making it an ideal choice for grinding down heavy welds, chamfering edges, and removing surface imperfections without glazing.

One of the critical challenges in grinding stainless steel is heat management. Excessive heat can lead to discoloration and warping of the workpiece. This "SS Value" disc is formulated to grind cool, dissipating heat effectively through its layered flap design. The Type 29 conical profile allows the operator to maintain a natural 15-25 degree angle, maximizing surface contact and providing greater leverage for aggressive material removal. This shape is particularly beneficial for contour work and getting into tighter corners where flat discs might struggle.

For fabrication shops, consistency is key. Pferd's manufacturing process ensures that each flap disc wears evenly, exposing fresh, sharp grain throughout its life cycle. This self-sharpening action maintains a high cut rate from the first spark to the last, reducing the frequency of disc changes and improving overall shop productivity. Compatible with standard 4-1/2" angle grinders using a 7/8" arbor, this disc is a versatile staple for any MRO or fabrication inventory.

Key Applications

• Heavy weld seam removal on stainless steel tanks and vessels.
• Chamfering and edge beveling prior to welding.
• Surface grinding and blending on alloyed steels.
• Deburring flame-cut or sheared edges.
