                     WHAT ARE RESIN FIBER 
DISCS & THEIR TYPES?
WHAT ARE RESIN FIBER DISCS?
Resin Fiber Discs are far and away the top popular 
coated abrasive product utilized in the industry. 
Constructed with an important vulcanized fiber back, 
they're covered with abrasive grains and bonded with 
a troublesome, heat resistant resin. It leads to a 
durable, calm, and fast-cutting action. The right sort 
of grinding abrasive is out there, so you'll select the 
materials best suited to your specific applications.
TYPES OF RESIN 
FIBER DISCS
The abrasive grain is what's doing the 
addition of any abrasive product. The 
grain utilized in a fiber disc determines 
the disc's cutting speed, life, and cost 
ratio.
There are four types of abrasive 
grains used for resin fiber discs.
ALUMINUM OXIDE
Alumina is the most familiar abrasive grain and delivers 
excellent cut rates and sturdiness. This Aluminum Oxide 
Resin Fiber Disc is a popular and commonly used 
abrasive grain that tends to lower the user's initial cost.
• AO – Open coat: Economical choice for 
general-purpose grinding and finishing.
• 2A – Closed coat: For general purpose 
grinding and finishing of ferrous and non-
ferrous metals.
• 3A – Closed coat with grinding aid: For 
general purpose grinding of chrome steel 
and aluminum.
ZIRCONIUM
Zirconium, the foremost popular grain utilized in fiber 
discs, features long-life when used in high 
applications that include blending, deburring, and 
weld removal.
• AZX: It is an economical choice for fast 
grinding and finishing application.
• Z-Closed coat: For aggressive stock removal 
and long life on ferrous and non-ferrous metals.
• 3Z-Closed coat with grinding aid: For fast and 
efficient grinding of chrome steel and 
aluminum.
CERAMIC
Ceramic grain's maximum productivity and performance 
are tough to beat. Ceramic grain easily removes material 
and is the right choice for users who want to urge work 
done faster. 
• 7AS – Ceramic Blend: Unique blended 
ceramic fiber disc for economical grinding.
• 7S – Closed Coat: For very aggressive 
stock removal and extraordinary life on steel 
and alloys.
• 9S – Closed coat with grinding aid: for top 
performance grinding of chrome steel and 
aluminum.
