Description of π³ Starrett 4 Inch Hole Saw with Carbide Tip
A cost effective solution for cutting nail imbedded wood, or wood and metal combination, reinforced concrete and fiberglass. Leaves high quality surface finish on entry and exit and provides a smooth cut when cutting traditional lathe and plaster. Tungsten carbide tipped teeth for outstanding cutting performance and product durability. Will cut nail embedded wood or virtually and wood and metal combination and suitable for use in mains and battery operated tools. 1-5/8-inches cutting depth.
Not a ton of carbide, not as much as pictured but it's there. I made some holes in the marine plywood. Disembarking was also easy with the major ports.
I ordered 6 1 3/4" Carbide Tip Bits and a split order of 4 (today) was short: 1 hole saw and item I Didn't order from Starrett Measure Stix. (see fig.). Waiting for the other two hole saws scheduled for tomorrow.
Very happy with this hole saw. The purchase price was slightly below that of well-known bi-metal crowns. I love carbide tips, they cut a variety of materials with ease and stay as sharp as new. I will definitely buy more!
