Drilling holes in rubber

 · I used core drills to drill bolt holes in rubber conveyor material when I worked maintenance. However this time I also had to drill through the aluminum sleeve the rubber ball is mounted on. So I didnt think the hollow tube thing would work too well, but it might have been just the ticket. I just didnt have any material on hand for that and after a couple of tests with the endmills I felt .

Overburden and Construction Tooling

TDN inner drill rods for dualstring drilling systems are an alternative to T38 and T45 extension drill steels. This thread design handles strong percussive forces while reducing the annulus between the casing and the inner rod. The smaller annulus results in better flushing from higher uphole fluid velocities allowing for higher penetration rates.
