Freud DHSAR375 Hole Saw Mandrel Arbor 3/8 Inch Hex

Product Description

The FREUD DHSAR375 is a snap lock hole saw mandrel arbor designed to simplify and speed up hole saw attachment and removal. It features a 3/8 inch hex arbor shank, a 4 inch pilot bit, and includes both a 1/2 inch and a 5/8 inch adapter nut to accommodate different hole saw thread patterns. The mandrel delivers a 2-3/8 inch cutting depth, allowing tradespeople to complete deeper cuts in a single pass. A Perma-Shield coating reduces friction and heat buildup during operation. Electricians, plumbers, and HVAC technicians who cut through framing, drywall, and wood substrates will find this mandrel a practical addition to their hole saw setup.

This mandrel arbor is suited for residential and light commercial installation work where repeated hole saw mounting and dismounting slows productivity. The snap lock design eliminates the need for wrenches during bit changes, and the tool-free plug ejection feature clears cut slugs without stopping to use a separate tool. The included pilot bit and dual adapter nuts make this a complete mandrel kit ready to run with standard hole saw configurations encountered in everyday trade work.
