Core Drill
April 17th, 2011
I am looking for a company that produces a rubber core drill that drills a 7/16 hole in 1″ thick rubber.?
Drill is approximately 8-10″ long and cores the hole in the rubber. The core is then ejected through a half moon cut out on the side of the hollow core drill bit. I know they use a smaller one on snowmobile tracks but this is much larger.
You can make one of these (or at least I could) from heat treated tubing.
Have to plan ahead as there is some “spring back” of the material
I am guessing a little,and there are some factors concerning the hardness of the material but around .450 may be correct.
Really need to see the material.
