Teflon PTFE thread sealant tape 1/2″ X 520″ is a low density PTFE thread sealant for all services and can be used on all types of threaded metal/plastic pipe connections & effectively seals a vast array of chemicals. We manufacture super premium drills with a special high molybdenum tool steel that can harden the steel to a range of 64.5 to 66 Rockwell C. This range is tighter than the standard industry specifications of 93.5 to 66 Rockwell C. This tighter specification yields a more consistent drill with a higher average hardness and therefore has more resistance to wear. Our mechanics length drills as well as our S & D drills have 3 flats on the shank. These flats allow for a strong positive chuck grip of the shank and virtually eliminate the potential for the drill to slip in the chuck, even if all 3 jaws have not been tightened securely. Flats are a very strong feature for maintenance and associated hand drilling applications. The Magnum™ series is an effective replacement for cobalt drills in work hardening stainless applications. The key to Magnum's performance success against cobalt is the difference in the point and web construction. It cuts softer material and has a longer life than the cobalt drill.
