The Challenge

The customer needs to drill holes in I-beams made from A36 structural steel. They just purchased a new Peddinghaus PCD 1100 Beam Drill Line.

The customer needed to reduce costs by decreasing the tool failure. Also, the machine operator was unhappy with the long stringy chips produced by the Nachi drills.

The Original T-A structural steel drill provided excellent chip formation (tightly curled 6’s and 9’s). More importantly, the drill eliminated the tool breakage issue.
