Calloytool Step Drills

Calloy Manufacturing introduced a line of new Step Drills made from premium cobalt M42 High Speed Steel with a TiN coating which improves tool life.

The step drills also feature an angled double flute which increases penetration rates and reduces the force needed when drilling. Starting the hole is made easy with the Calloy split point.


The new Step drills are available in three sizes: Part No 35200 for sizes 1/8” to ½” for 1/8” materials. Part No. 35201 for sizes 3/16” to ½” for 3/8” materials and Part No. 35202 for sizes 3/16” to 7/8” for 1/8” materials.


In addition to the new step drills, Calloy Manufacturing provides machine shops, fabricators, erection and installation crews, and maintenance personnel with a wide range of holemaking equipment, from lightweight ultra low profile drills to large heavy duty production style magnetic drills. Other products offered include a wide assortment of magnetic drill accessories that broaden their application potential, plus a wide range of annular cutters, heavy-duty industrial annular cutters for machining applications, cutters for holemaking in sheet metal and plate, and Punch-Pro Electro-hydraulic Hole Punchers.
