Stanley 1779774 Arbor with Pilot Drill Bit 3.25 Inch

Product Description

The STANLEY 1779774 is a T2-shank arbor with an integrated pilot drill bit, designed for use with hole saws in trade and industrial drilling applications. The 1L arbor configuration accepts standard hole saw attachments and keeps the pilot bit centered during cutting, reducing walk-off and improving bore accuracy. At 3.25 inches in length, this arbor is suited for use with a wide range of hole saw diameters. Electricians, plumbers, and general contractors use this type of arbor when boring through framing, panels, or conduit pathways where a secure, repeatable pilot is required.

This arbor is a practical addition to any tool kit where hole saws are used regularly on jobsite or shop work. The T2-shank designation ensures compatibility with standard drill chucks and hole saw systems that accept this interface. Sold individually, it works across residential and light commercial drilling tasks.
