Description of π³ Milwaukee 49-56-0158 8" Hardened Hole Saw
The product is easy to use. The product is durable. The product is manufactured in United States. ICE HARDENED for up to 50% longer life than the competition. Matrix II Bi-Metal Teeth for greater durability. Positive Rake Angle for fast cutting. Radiused Tooth Back reduces stress on teeth. Deeper Gullets for fast chip removal and Funtional Slot Geometry provides easy plug removal.
The hole saw itself is great but it doesn't come with a spring loaded drill. So make sure you have it, otherwise it's useless. Luckily I did just that.
This hole saw wore out before I could finish my first hole. I have previously purchased a hole saw kit, same hole saw was included and it worked great, got this one and it barely cut 1/32 inch. I cut steel and didn't expect it to last very long but having the previous blade cut 5 holes before dying this was a real disappointment.
