Park Tool DT-5/DT-5.2 2197 Diamond Abrasive Adaptor For Carbon Fiber

The is an add-on tool for the Park Tool DT-5 and DT-5.2 Disc Brake Mount Facing Set that allows for easier and more efficient machining of disc brake mounts on carbon frames. It features a brazed-on diamond grit surface that is over 100 times more durable and effective on carbon fiber than the cutter included in the DT-5.2.

The 2197 Diamond Grinding Attachment sits between the DT-5.2’s cutter and the brake mount and gently and evenly grinds the bearing surface until it is flat and properly perpendicular to the brake disc.

The Park Tool 2197 Diamond Grinding Attachment is compatible with postmount and flatmount disc brake mounts.

 

. Aluminum, steel and titanium disc brake mounts should be machined with the 2171 pad cutter included with the DT-5.2 Disc Brake Mount Facing Set.

For carbon frames with aluminum inserts (with a carbon/aluminum hybrid mounting surface), use the 2197. When machining carbon, you should regularly apply water (or a similar solution) to the cut surface.
