Bon Tool Ultra Hard 'S' Jointer - 0.625 X 0.625-Inch

The primary use is to create concave joints in wet concrete, often for decorative or functional purposes in sidewalks, patios, and other concrete surfaces.

The 'S' shape allows for versatility in application by enabling the user to adjust the angle at which the jointer contacts the concrete, thus altering the resulting joint profile.

The dimensions are 5/8" x 5/8" (0.625 x 0.625-Inch).

No, this tool is specifically designed for creating concave joints. It is not suitable for flat or convex joints.

It is constructed from ultra-hard, heat-treated material for enhanced durability and longer wear life, even under demanding use.

With a weight of 0.26 pounds, the jointer is lightweight, which helps reduce user fatigue during extended use.

This product is made in the USA.

Ensure consistent pressure and angle throughout the pass. Check for debris on the jointer's edge.

Slightly wet the jointer's surface before use, or ensure concrete is at the appropriate working consistency. Clean the jointer thoroughly after use.

Confirm you are using the tool on concrete at the correct finishing stage. Excessive force or use on hardened concrete can accelerate wear.
