Review on 🔪 Improved MK Morse AV68 4 Inch Bi Metal Blades by Jack Robi

Excellent product, worked exactly as requested. I bought 8 LED recessed lights to improve the lighting in my kitchen. This required drilling 3-7/8" holes in the plasterboard ceiling. This hole saw was the exact diameter. The only reason I'm giving it 4 stars and not 5 is because neither Revain nor the supplier have emphasized the fact that it requires a 5/8'-18 hole saw arbor instead of the more common hole saw arbors. This caused some inconveniences and delays. Revain and the supplier are listening to see if I can suggest that you (1) highlight the fact that this hole saw requires a 5/8-18 arbor and (2) recommend an appropriate arbor along with this product .
