Lenox 3 1/2 Inches Hol Bi-metal Hole Saw 3-1/2 Inches

Product Description

The LENOX 3 1/2" HOL is a bi-metal hole saw designed for cutting through common construction materials including wood, metal, and composite substrates. The proprietary toothform geometry is engineered to extend service life compared to standard bi-metal hole saws, with a reinforced tooth design that absorbs impact forces during bind-ups and contact with obstructions. This reduces tooth breakage during aggressive drilling. The SPEED SLOT staircase design built into the saw body allows cut plugs to be ejected quickly without stopping the drill, keeping work moving on rough-in and retrofit jobs. Licensed electricians, plumbers, HVAC technicians, and general contractors use this tool for framing penetrations and knockout work.

This hole saw is suited for residential and light commercial construction and service applications. It is appropriate for drilling through wood framing, low-carbon steel panels, PVC, and similar construction materials encountered in mechanical and electrical rough-in work. The 3-1/2 inch cutting diameter fits common pipe and conduit clearance holes. It works with both quick-change and traditional non-quick-change arbors, making it compatible with the majority of standard hole saw arbor setups already in a technician's kit. Note that proprietary arbor systems requiring dedicated adapters are not supported.

Installation Notes

Install the hole saw onto a compatible arbor following the arbor manufacturer's torque and engagement guidelines before operating. Ensure all power to the drill or driver is off before mounting or removing the saw. Use appropriate eye and hand protection when drilling through metal or composite materials. Confirm the cutting diameter meets the clearance requirements of the applicable mechanical or electrical code before drilling into structural or fire-rated assemblies.
