Castle pocket hole bits4/4
I just picked up a used Porter Cable 552 (Castle clone) pocket hole machine and need to get new bits. At my old job we used the Castle 3 flute carbide bits but I am wondering if others are using better or less expensive alternatives for general use in plywood, mdf and hardwoods.
Look in one of the big machinery books like McMaster or MSC.
The cutter you are looking for is a 3/8" solid carbide roughing end mill for aluminum.
I got one that was coated in something better than titanium nitride and laser sharpened for not that much money. It was still sharp after 10 years of decent use.
It mows thru plywood/hardwood and doesn't get dulled particleboard/mdf.
We have both Carbide-tipped and solid carbide. If you need a source, give us a call 877-465-7012
