The tang, which is the flattened section found on the end of a Morse taper shank drill bit, is created using a milling machine. This specific machining process shapes the tang so it can properly fit and be secured within the chuck of a drill press or lathe.
The Machining Process: Milling the Tang
Based on manufacturing processes for large drill bits, a key step in creating certain types of drill bits is machining the tang. The tang serves a critical purpose: ensuring the drill bit is securely held and driven by the machine tool.
- Part Being Machined: The Tang (the flattened section of the Morse taper shank).
- Machining Method: Milling Machine.
Utilizing a milling machine allows for the precise removal of material to form the characteristic flattened shape of the tang. This shape is essential for the tang's function, as it engages with a slot in the machine's spindle or chuck adapter, preventing the bit from rotating during operation and allowing for easier removal using a drift key.
This milling step is a crucial part of the manufacturing process for drill bits featuring a Morse taper shank, preparing the tool for its intended use in applications requiring a secure and robust connection to the drilling or turning machine.
