Lockmasters' Ball Hog Bits will stand up to the test of drilling ball bearing hard plate. We pushed it to the limits and it withstood all we could ask. The cutting portion of the bit is titanium nitride coated tungsten carbide for extra cutting life. All sizes come in 6" lengths but can be cut down to your desired length. All bits come with complete instructions and wooden plugs for stabilizing ball bearings.
