Ingco 3/8-Inch Hex Shank Hole Saw Arbor | Premium Carbon Steel Mandrel Adapter with 9.5mm Shank and Replaceable Pilot Drill Bit for Hole Saws (HSA01)

The Ingco HSA01 Hole Saw Arbor is a professional-grade mandrel adapter engineered to securely connect hole saw blades to standard power drill chucks for precise, high-speed drilling. Featuring a universal 9.5mm (3/8-inch) hex shank, this arbor is designed to fit a wide range of cordless and corded hand drills, preventing slipping inside the chuck during high-torque operations in wood, plastic, and thin metals.

Manufactured from high-strength carbon steel, the arbor undergoes advanced heat treatment to ensure excellent durability and resistance to rotational stress. It comes equipped with a central high-speed steel (HSS) pilot drill bit that guides the hole saw precisely into the material, preventing wobbling or walking before the main teeth engage. The pilot bit is easily adjustable and replaceable via a secure hex set screw. This robust mandrel provides the structural stability needed for clean, concentric, and tear-free large-diameter cuts on any job site.
