Description of Efficiently Cut Aluminum and πͺ Copper with Uxcell Bi Metal Cutting Tool
2-13/16 Inch (71mm) Bi-Metal Hole Saw. Easy to use. Bi-Metal Construction - for toughness and long life. Sharper Tooth - cut holes in aluminum, copper, iron, and zinc drywall, wood. Variable Pitch Teeth - for reduced noise and improved performance. Variable Depth Gullets - provides more efficient chip clearance.
I have a lot of bits, obviously not this size but right away the chuck barely turns a 3/4 turn. Now I need to find a faucet to put out the streams. I will update after making some holes.
Pros
Adjustable depth indentations - provide more efficient chip evacuation
I have other hole saws (red) from other manufacturers and they do at least 15-20 holes in the material that I drilled This drill bit was only enough for one hole, I ended up having to make a fixture and use a router to cut the remaining 29 holes. Delivery was quick but the quality was disappointing.
Pros
Sharper tooth - cutting holes in aluminium, copper, iron and zinc Drywall, wood
