2 Piece Boring Mill Jaws from H&R Mfg. and Supply, Inc. feature a cast steel base (much stronger than cast iron), superior clamping force, and an extra-heavy duty model with up to 25,000lbs workload capacity per jaw.
H&R's boring mill jaws feature super-tight screw pitch to hold workpieces steady during operations. This helps produce the highest number of good parts when used properly.
Two piece jaw systems afford the maximum flexibility and stroke movement per jaw out of a single set up. This helps avoid costly downtime when fine tuning set ups, since it's not necessary to move the base for small diameter changes.
H&R's 8640 cast steel bases are much more resistant to wear and tear of everyday operation compared to standard cast iron bases. In some cases, cast steel can also save the cost of replacement by affording some leeway for repair via welding, whereas cast iron can not.
Our specially designed low profile boring mill jaws sit lower to the table and give set ups an extra inch of work space, so taller pieces can be accommodated. Low profile models also feature dual thrust bearings which increase the workload capacity to 25,000lbs per jaw.
