Floating Reamer Holder

A floating reamer holder is a precision accessory designed specifically for reaming operations;

its primary function is to automatically compensate for concentricity errors between the machine spindle and the center of the hole in the workpiece.

In machining, if the spindle and the pre-drilled hole are not perfectly aligned, a rigidly held reamer is forced to cut aggressively,

leading to issues such as oversized holes, ovality, or skewed holes.

The floating reamer holder allows the reamer to float freely within a small range—moving 360 degrees—

thereby ensuring stable machining as the reamer follows the precise path of the pre-drilled hole.
