Wool Felt bob

Wool Felt Bob

Wool Felt Bob are made from selected long fiber wool and contain no resins, lacquers, or synthetic fibers. Hardness or density is achieved through carefully controlled fulling and hydraulic pressing.

SOFT
Soft wheels are generally used for rounded surfaces and for special applications requiring minimal pressure and cutting action.  This density is used quite generally in glass, granite and marble work.  

MEDIUM
Medium polishing wheels are recommended for most industrial work and readily adapt to either flat or rounded surfaces. they are often used in buffing and color buffing operations in conjunction with other cutting agents and lubricants.

HARD
Hard felt wheels are usually used on flat surfaces or in applications where it is necessary to contour the wheel to the configuration of the piece part. This is the density normally used by lapidarists and jewelry manufacturers.

ROCK HARD
Rock hard felt wheels are used in operations demanding maximum cutting pressure and where sharp edges or critical contours on the piece part require close tolerance or complex wheel shaping.

STORAGE
Store spare wheels in a dry, protected place. Stack the wheels, one exactly on top of another and well above the floor.  Keep all excessive heat and moisture away.
