This Hole Saw Kit is designed for wood / plastic cutting. Made of High Speed Steel / Bi-Metal, Durable and no Rust. Includes one 3.75-inch hole saw, with one pack hex shank drill bit adapter. Drills in clockwise rotation.
This industrial and scientific hole saw accessory exceeded my expectations. Thanks to my knowledge gained in practice, I can assure that this tool is worth every penny. The arbor is sturdy and helps in easy drilling with minimal pressure. The saw blades cut through the material with precision and ease. The only downside is that it is not suitable for thicker materials. Overall, a great addition to my cutting tools collection.
Pros
Efficiently cuts holes of varying diameters.
Cons
May not fit on some types of drills, resulting in the need to purchase a separate arbor.
Does the job at a reasonable price. 1 star deduction because the material stays in the saw and is not thrown away. I had to pry it out with a screwdriver each time. Note that the teeth are coarse.
