These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, ground, and polished to meet tight diameter and straightness tolerances.

Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 316 stainless steel shafts have excellent corrosion resistance.

Smooth, hard, and wear resistant, linear motion shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. All are turned, ground, and polished to tight diameter and straightness tolerances.

Stainless steel shafts are more corrosion resistant than steel shafts; however, they’re not as hard as steel shafts and can be more difficult to machine. 17-4 PH stainless steel shafts have excellent corrosion resistance and high yield strength to support heavy loads.

Hardened shafts are heat treated for increased wear resistance.
