Charnwood Bowl Gouge - 3/8''

Cryogenic hardening involves cooling the High Speed Steel (HSS) blade to extremely low temperatures (as low as -195°C) after heat treatment. This process refines the steel's microstructure, significantly increasing its hardness (to 65HRC) and wear resistance, leading to a much longer-lasting sharp edge.

Due to the cryogenic treatment, this gouge typically lasts 5 times longer between sharpenings than standard HSS chisels, meaning you'll need to sharpen it less frequently.

While the performance benefits are substantial, beginners should ensure they are comfortable with sharpening techniques for woodturning tools. The tool itself is designed for controlled cuts, making it effective once basic woodturning principles are understood.

The flute width is 7mm (1/4'').

The blade length is 220mm, and the handle length is 320mm.

This bowl gouge is specifically designed for shaping bowls and curved forms. For spindle turning, a spindle gouge would be more appropriate as it has a different flute shape and grinding profile.

The Ash handle is durable. Keep it clean and dry. Periodically, you can apply a light coat of wood finish or oil if desired to maintain its appearance and protect the wood, but it is not strictly necessary for function.

The blade may be dull. Resharpen the gouge following manufacturer guidelines. Ensure the tool rest is at the correct height and angle relative to the workpiece.

Check that the gouge is securely mounted on the tool rest and in the lathe chuck if applicable. Ensure the workpiece is balanced. A dull or damaged edge can also cause vibration.

Inspect the ferrule and handle connection. If loose, consider applying a small amount of wood glue to the tang and reinserting it firmly into the handle. Allow to dry completely.

Wipe the blade thoroughly with a cloth and a fine abrasive (like very fine steel wool or a polishing compound). Apply a light coat of paste wax or specialized tool oil to prevent future rust. Ensure the gouge is stored in a dry place.
