Flap Discs 3M Cubitron II 967A 115mm x 40# (10/bx)

3M Cubitron II Flap Disc 967A is ideal for low to medium-high pressure applications on flat surfaces or outside edgework, especially in paint prep and stainless fabrication where final finish and gouge resistance are important.

Cubitron II 967A Flap Disc capitalizes on our proprietary 3M Precision Shaped Grain technology to deliver superior cut rates, while the flexibility of the flap construction enables grinding and blending in a single step.

Our 3M Precision Shaped Grain generates an exceptionally high cut-rate with less pressure, operators can finish tough tasks like weld grinding, deburring, rust removal, edge grinding, weld seam blending, and deburring faster and with less fatigue.  A heat-activated grinding aid on the disc makes this an outstanding product for all types of metal - it helps keep the disc cooler on stainless steel and heat-sensitive metals such as nickel alloys and titanium, thereby reducing metal discoloration/oxidation and the chance of heat-related stress cracks.

The superior performance and durability of 3M Precision Shaped Grain is enhanced by a uniquely designed heavy Y-weight poly-cotton backing that enables controlled, even wear with no premature dulling or glazing, so operators can accomplish more throughput per disc. 
Flap discs run on a right angle grinder.  For attachment, 4-1/2" flat discs with a centre hole require a flap disc adaptor nut, and 7" discs require a flap disc holder (both sold separately).  Discs with a 4-1/2" diameter have a max RPM of 13,300, and 7" discs have a mix RPM of 8,600.  Use Type 27 on flat surfaces or outside edgework.  3M Cubitron II products have raised the bar for high-performing abrasives.  3M Precision Shaped Grain offcuts and outlasts conventional ceramic industrial abrasives and requires less grinding force to achieve superior performance.  The result is that operators can grind faster and complete more parts per disc with less muscle-work and fatigue.
