Mini Mandrel for Cartridge Rolls

The 3M 935 Mini Mandrel holds cartridge-roll abrasives on a straight 1/4 in shank for use with rotary tools. Its compact 2 7/8 in overall length suits detail sanding and finishing in tight spaces. The accessory is rated for a maximum operating speed of 14,000 RPM. It is designed for operators who need a small, precise holder for roll abrasives.

Best for detail work, not heavy stock removal

This mandrel suits technicians finishing metal, wood or composite surfaces where access is limited and control matters. It does not serve users who need a larger arbor for flap wheels, large-diameter discs or aggressive material removal. Buyers requiring a pilot or threaded mounting should look at alternative holders.

1/4 in straight shank fits standard collets

The 1/4 in straight shank seats directly into common die-grinder and rotary-tool collets without adapters. Verify that your tool accepts this shank diameter and can run safely at 14,000 RPM before purchasing. This single fitment detail determines whether the mandrel works with your equipment.

Questions about this item

Does the 3M 935 Mini Mandrel require any scheduled replacement parts or consumables?

The mandrel itself is a durable steel holder; only the cartridge-roll abrasives it grips wear out and need replacing as they are used.

What limits continuous operation at the rated 14,000 RPM?

Heat build-up in the workpiece and abrasive degradation are the first practical limits; the mandrel has no internal wear items that fail at speed.

How much vibration or heat does the 3M 935 generate during all-day use?

Vibration and heat come mainly from the spinning abrasive and workpiece contact; the solid 1/4-inch shank runs true, adding minimal extra vibration.
