5/16" to 1-1/8" Pipe Capacity, Tube Cutter MPN:133

A woodruff key seat cutter is a specialized cutting tool used to create mating surfaces on shafts and hubs which fit into one another securely using spline joint. The cutting head of this particular model measures 0.875in in diameter with a width of 0.125in, suitable for precision engineering applications requiring high-quality keyseats with minimal tolerance variation. Its 3/8in shank ensures compatibility with most drilling machines or lathes and provides stability during operation. Straight tooth geometry enables consistent cutting performance across multiple materials like steel or cast iron for reliable performance in industries such as automotive, machining or equipment manufacturing where accurate mating surfaces are crucial to optimal functionality of assemblies.
