Abstract: A tiered level cutting system (20, 30, 40, 50, 60, 70, 80, 90) and method that guides a user through the process of selecting an appropriate tool or adapter for specific cutting conditions and/or applications. The cutting system (20, 30, 40, 50, 60, 70, 80, 90) may include a plurality of blocks (22, 32, 42, 52, 62, 72, 82, 92), one or more sleeves (24, 26, 34, 35, 54, 64, 84, 93, 94, 95) for each block, and a plurality of cutting tools (27-29, 36, 37, 45-47, 55-57, 65-67, 75-77, 85-87, 96-99). The method includes the steps of selecting a block (22, 32, 42, 52, 62, 72, 82, 92) for user's particular operation, optionally, selecting a sleeve (24, 26, 34, 37, 45-47, 55-57, 65-67, 75-77, 85-87, 96-99) based on the selected sleeve. The cutting system (20, 30, 40, 50, 60, 70, 80, 90) is selected based upon the type of machinery and cutting environment. The block (22, 32, 42, 52, 62, 72, 82, 92) is selected based upon the type of machinery and cutting environment. The block (22, 32, 42, 52, 62, 72, 82, 92) is selected based upon the particular operation. Operation categories may include severe, heavy, medium and light based upon conditions. The cutting tool (27-29, 36, 37, 45-47, 55-57, 65-67, 75-77, 85-87, 96-99) is selected based upon the shape and carbide content. The steps can be performed in most any suitable order.

Abstract: A drill steel-chuck assembly which includes a drill steel (26) which has a plurality of faces (56-66) and opposite ends. The drill steel has one portion (74) adjacent one of the opposite ends thereof and an intermediate (76) portion spaced apart from the one portion. The drill steel further has one transition portion (78) between the one portion and the intermediate portion so as to join the one portion and the intermediate portion. The one portion of the drill steel presents a first orientation of the faces. The intermediate portion of the drill steel presents a second orientation of the faces. The one transition portion (78) of the drill steel presents a twisted orientation of the faces comprising a generally constant twist of the faces from the first orientation of the one portion to the second orientation of the intermediate portion. There is a chuck (26) for attachment to the drill steel through engagement with the transition portion of the drill steel.
