Dolphin Rough Boring Head Thread Pitch 1.1/2 Inch x 18

Dolphin Rough Boring Head Thread Pitch 1.1/2 Inch x 18" refers to a specific type of rough boring head with a threaded connection designed to fit a machine tool spindle or adapter with a thread pitch of 1.1/2 inches and 18 threads per inch (TPI). This threading specification is crucial for ensuring compatibility and secure attachment of the boring head to the machine tool.

Here's a breakdown of the key details related to this specification:

1. Thread Pitch: The thread pitch of 1.1/2 inches x 18 indicates the distance between successive threads on the threaded portion of the boring head. In this case, the pitch is 1.5 inches (or 1.1/2 inches) per complete turn of the thread, and there are 18 threads per inch (TPI). This threading specification is essential for matching the boring head with the corresponding spindle or adapter on the machine tool.

2. Thread Type: The threading specification provides information about the type of threads (in this case, 18 TPI) and the diameter of the threaded portion, which is critical for ensuring a secure and precise fit between the boring head and the machine tool spindle.

3. Compatibility: The specified thread pitch and size must match the corresponding thread on the machine tool spindle or adapter to ensure proper installation and alignment of the boring head. It's important to confirm compatibility based on the machine tool's specifications and thread standards (such as Unified National Coarse, UNC, or Unified National Fine, UNF).

4. Dolphin Brand: The Dolphin brand is associated with this specific type of rough boring head, which may offer additional features and capabilities tailored for rough machining applications in various industries.

5. Application: Rough boring heads are commonly used for enlarging and refining existing holes or bores in workpieces, particularly in roughing operations where material removal rates are high and surface finish may be secondary. The specified thread pitch and size ensure that the boring head can be securely mounted on the machine tool for efficient and accurate machining.
