JUST SOME "BITS" AND PIECES


  The hole saw can be a friend or a fiend. It all depends how you learn to use and respect it. Besides the need for a lot of steady torque, hole saws work best when run according to the max speed recommended on the side of the hole saw itself. Running a hole saw too fast, does not cut faster. Running it too slow and you run the risk of it binding, chattering, and or skipping to the point where it could snap the center guide bit.

  The chart below lists the drill by cat # and the recommended maximum bit that should be used. Since these model numbers are for Milwaukee products you need do a comparison with a drill you own. The best way to use this chart is  to look at the "twist drill" specification for Wood and Fiberglass, which is considered the maximum size for the chuck of each of these drill models. Then compare across to the maximum size recommended for other bits.
   For example, the 1/4" twist bit, (top row) maximum for a small drill that runs 2000 rpm, has a maximum hole saw capacity of  1 3/4". If your trying to use a larger hole saw it that drill, you run the risk of damaging the drill, the boat, and yourself. The drill isn't designed to do the job.

   Match the hole saw, the drill, and drill speed to the recommended specifications of the tools. You'll experience less hole saw skip, meaning less damage to the boat, because it'll be easier to control the drill.
   Remember that some hole saws have the recommended saw speed stamped into the housing of the hole saw.

Hole saw tip: When cutting thru carpeted or vinyl covered panels... run the hole saw backwards to cut thru the soft material to prevent ripping. When you get down to the panel, change saw direction back to normal to cut the panel material.
