Review on 🔧 Enhanced Performance: Bi Metal 8 Inch Klein Tools 31958 – Perfect for Professional Use! by Ronald Reese

Luckily I have had to cut 1/2 inch drywall with a hole saw so far. I bought a real saw arbor with pins and the "correct" pin holes in the saw are not in the right position. Terrible quality control. If I need to drill into something rigid this can be a problem. I bet if I paid for the return postage the replacement wouldn't be in the middle either. Shame.
