All tips are made of high strength alloy steel and are heat-treated for added durability. Tapered edges make penetration and withdrawal easier.
The ball nose tip has a slightly rounded nose for delicate probing operations such as: fiber optics, gas transmission lines, water lines, and other utilities.
The tips are available in three sizes: 3/8", 7/16", and 1/2". The sizes describe the size of the rod that the tip was designed for. The 3/8" tip works with both the 3/8" round rod and the 3/8" hex rod.
The actual size of the tips is a little larger than the shaft. This allows the tip to create a clearance hole so the rod will not drag against the ground.
