3M™ Cloth Disc 747D, 80 X-weight, 12 in x NH, Die 1200B

The 3M™ Cloth Disc 747D is constructed with a blend of 3M™ Ceramic Abrasive Grain and premium aluminum oxide to give you increased durability and cutting efficiency over non-ceramic abrasives. The disc is backed with a strong X-weight cotton cloth backing that handles edgework without tearing. Choose this disc for use on stainless steel, cobalt chrome, titanium, and carbon steel for dimensioning parts, deburring, blending, and scratch refinement on castings and forgings.

To protect heat sensitive alloys such as stainless steel, nickel alloys and cobalt alloys from heat-related stress cracks and discoloration, a grinding aid incorporated on the disc reduces running temperatures and prolongs the life of the disc. Additionally, the abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure.

3M™ Ceramic Abrasive Grain is a ceramic mineral designed using a 3M proprietary process to enhance toughness and hardness of the grain. For increased performance, 3M™ Cloth Disc 747D features aluminum oxide blended with 3M ceramic grain for a harder, longer-lasting abrasive. Perfect for light to moderate stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications. Ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability and makes Disc 747D an excellent choice for moderate stock removal and surface preparation.

3M can provide customization of this disc to fulfill your exact diameter and attachment specifications. The 3M brand, across thousands of products, represents consistency, superior quality, and value.
