785C Grinding Discs - Aluminum & Fiberglass

Cubitron-Aluminum Oxide Blended Abrasive With Multiple Attachment Systems

These 785C grinding discs represent the high performance end of 3M's general purpose disc offerings.
 
They are a good starting point for grinding a variety of substrates including aluminum, nickel bronze, stainless steel and other softer metals, as well as fiberglass and composites.
 
 
785C uses a blend of long-wearing Cubitron ceramic and aluminum oxide minerals.
 
785C cuts cooler and faster than 510C alumina zirconia discs, with lower heat build up and less discoloration of the work piece making it ideal for leveling stainless steel welds and working with high nickel alloys.
 
These 785C discs are the "go to" discs for use on marine grade aluminum alloys.
 
 
Grinding aid for cooler running temperatures and less loading
 
Tough, but flexible, fibre backing
 
Long life
 
Fast cutting
 
Offered with GL Grit-Lok or 5/8-11 TN quick change attachments
 
A "P" grit rating indicates that the abrasive mineral meets international standards for particle size consistency
 
 
User Tip Especially with coarser 36 and 24 grits, we recommend the use of an extra hard red ribbed backing plate for cooler running and prolonged disc life; see Related Products, below.
 
 
 
For higher performance discs, consider 3M's 985C (3M's original pure Cubitron disc), recommended for use on stainless steel.
 
An economical alternative would be 3M's lower performance 381C aluminum oxide disc; see Related Products, below.
