Magnetic Workholding Chucks
To grind, drill, lightly mill, and machine parts that rotate around an axis, these chucks hold parts in place magnetically so you can access their inner and outer diameters. Use them when clamps will not fit or could damage the part’s finish. To switch the magnetic grip on and off, pull their handle. They have mounting holes for fitting in your machine, or your machine’s chuck can hold them.
Chucks with fine magnetic pole spacing hold parts that are smaller or thinner than 1/4".
Chucks with standard magnetic pole spacing grip large and thick parts. They’re good for most applications.
