Freud DHS4000 Hole Saw 4 in Wood Metal

Product Description

The FREUD DHS4000 is a 4-inch diameter hole saw with a 2.375-inch cutting depth, designed for high-performance boring through wood and metal in a single pass. The variable tooth geometry reduces vibration during the cut while maintaining aggressive material removal rates. A tool-free plug ejection system clears the bore without stopping work. The Snap Lock system allows fast blade changes with no downtime. This hole saw is built for electricians, plumbers, HVAC technicians, and general contractors who need repeatable, clean bores in a range of materials.

The DHS4000 is suited for residential and light commercial applications where deep, single-pass holes are required in wood framing, metal studs, sheet metal, and similar substrates. The 4-inch diameter makes it a common choice for pipe penetrations, duct openings, and electrical rough-in work. It is compatible with the Diablo Snap Lock mandrel system, which fits all Diablo hole saws ranging from 0.625 inches to 6 inches in diameter. Note that the mandrel and pilot bit are sold separately and are not included with this saw.
