Itm ARB-2 Hex Arbor 3/8 Inch Shank 1/2-20 Thread

Product Description

The ITM ARB-2 is a 3/8-inch hex shank arbor designed to drive hole saws with cutting capacities ranging from 9/16 to 1-3/16 inches. The 1/2-20 threaded connection provides a secure interface between the drill and the hole saw, reducing wobble and improving cut accuracy. At 0.17 pounds and 5.25 inches in length, the ARB-2 is a compact, lightweight addition to any tool kit. Electricians, wire and cable installers, and switchgear technicians rely on this arbor for repetitive hole saw work where consistent engagement and quick bit changes matter.

The ARB-2 is suited for electrical, lighting, and general trade applications where hole saws in the 9/16 to 1-3/16-inch range are regularly used. Typical uses include drilling knock-outs, conduit entry points, and wire passage holes in panels, enclosures, and structural members. The 3/8-inch hex shank is compatible with standard 3/8-inch and larger drill chucks commonly found on corded and cordless drills used in the field.

Installation Notes

Electricians and trade installers should ensure the drill is powered off and unplugged before attaching or removing the arbor. Thread the hole saw fully onto the 1/2-20 connection and confirm it is seated before operation. Follow applicable NEC guidelines when drilling through electrical enclosures or structural members. Inspect the arbor threads periodically for wear or damage and replace if deformation is present.
