Subland Drill (2-2-2)

Available in :
High Speed Steel, Carbide Tipped, Solid Carbide

Description
A Subland Drill (2-2-2) is basically three drills of different diameters combined into one tool, yet retaining the individual characteristics and proper geometry of each. The independent flutes and margins of the sublands means that concentricity between diameters is ensured throughout the life of the tool and is never affected by resharpening the point and step angles.

Applications
The Subland Drill (2-2-2) eliminates secondary operations by drilling multi-diameter holes in one production pass. On certain applications particularly when drilling three diameter holes in steel or cast iron, the subland drill (2-2-2) provides superior tool life compared to that of a basic stepped drill of the same diameters.

Limitations
This tool type is not recommended when the small diameter is less than 60% of the large diameter. Depth of hole should not exceed 3 times the smallest diameter but greater depth can be achieved by withdrawing the tool to clear the chips.
