Review on MK Morse MHSA46C Attached Diameter by Lagant Wardrick

This hole saw was purchased to drill through my truck trailer to install an outlet. Materials pierced were thin aluminum skin, 1 inch foam insulation and 1/4 foot plywood. As expected, this was not a problem for the saw and the installation was successfully completed allowing for a tight bin gap. does not really indicate the reliability of the product, I would buy this product again.
