Park Tool 687 Reamer Stop Description:
The Park Tool 687 Reamer Stop works with Park Tool HTR Reaming and Facing Sets to safely clean up press fit bottom bracket and headset interfaces within a frame. This stop replaces the facing bit so the outboard surface on the frame is not worked on, and creates a natural stopping point for the reaming process so the surface is cleaned up only to a prescribed depth to avoid removing too much material. This stop's 57mm diameter safely interfaces with any bottom bracket or headtube size, and the rugged materials and precise machine work ensures a long useful lifespan even when heavily used in a bike shop.
Features:
- Replaces the facing cutter on Park Tool Heat Tube Reaming and Facing sets when only the reaming function is needed for a head tube or press fit bottom bracket shell
- Stops the reaming process at the prescribed depth without machining the outer surface
- Rugged construction ensures this tool can hold up to heavy bike shop use and abuse
- 57mm diameter provides surface area to properly fit up against any press fit bottom bracket or headtube opening
- Compatible with Park Tool HTR-1, HTR-1B, and HTR-HS Reaming and Facing Sets; Reaming and Facing sets are available separately
