## Description

Koopi 3 Inch BI-METAL Hole Saw with Arbor and Replacement Pilot Drill Bit, Hole Cutter for Easily Drilling Wood, Plastic, Thin Metal （76mm）

Review: Worked great - Worked great for my wood project so I can't say how it will do on any other material.
Review: Perfect For My Needs - I needed to make a repair on a sealed piece of machinery. This hole saw let me make a perfect access hole in the heavy sheet metal. For the price, I figured I only needed to use the hole saw one time. I didn't even use any cutting oil. I kept the drill running at a fairly low, constant speed building minimal heat. The saw had no trouble cutting through the sheet metal. The paint on the teeth is still almost completely intact.
