Anyone with experience? I am considering a project that will require cutting hundreds of 1 5/8" holes in 1/2" hardwood. What type/brand of hole cutter is likely to give the best performance for the longest time? A cursory search of hole saws show "carbide tipped" and full carbide. Often the information talks of cutting metal. These are not inexpensive and I would like to avoid making a mistake.
Thanks for any help.
