Very nice deal for the carbide big hawg hole saw set with packout case (50% off). 9 piece set. Includes a variety of sizes from 2 to 4 inch, and includes 4-5/8" saw which sells for $61 alone.
The 10 piece set is also on sale for $110, but max saw is 4-1/4" and it comes in standard case instead of packout.
