3M™ Roloc™ 361F Cloth Disc

The 3M Roloc 361F is a cloth-backed abrasive disc with Roloc quick-change attachment and aluminium oxide grain. It is the all-round Roloc disc: grinding, blending, deburring and finishing on all types of metal, dry or wet.

Specifications

• Mineral: aluminium oxide.
• Backing: YF-weight polyester cloth.
• Bond: heat- and water-resistant resin.
• Attachment: Roloc type R.
• Diameters: 25, 38, 50 and 75 mm.
• Grits: from P24 to P240.

The Roloc system

The disc screws onto a holder mounted on a die grinder with a quarter turn. Changing takes a second, without tools: you switch grit without interrupting the work. Type R screws on; it is not compatible with type S holders.

Applications

Levelling spot welds and small weld beads, fettling, defect removal, cleaning rusty areas, removing paint layers and residual gaskets. The polyester backing suits medium-pressure applications and resists tearing well.

Choosing the grit

P24 and P36 for fast stock removal and weld levelling, P50 to P80 for cleaning and deburring, P100 and P120 for blending, P240 for finishing. The small 25 mm diameter reaches corners and internal areas; the 75 mm covers open surfaces faster.

For higher output in production, the 3M Cubitron II 984F uses the same attachment with a ceramic grain.
