Using Adjustable Hole Saw Cutter
Although adjustable hole cutters have been in use for many years, the new style with a clear plastic shield for use in a hand drill is a relatively recent development. The earliest models were designs that had a single cutting blade on a bar that could be adjusted for different size holes and different lengths of bars to add to the cutting bar to provide for better balance. The twin blade design of the Hole Pro adjustable hole saw cutter is a big improvement over the single blade designs in terms of performance and durability. |
