.4688" Spiral Taper Machine Reamer - 8-3/4" Long

The .4688" spiral taper machine reamer is a precision cutting tool designed for creating or enlarging holes in various materials. Its designation, 'spiral taper,' indicates that it features a tapered design with spiral flutes that help in guiding the reamer through the material while effectively clearing debris. This specific reamer is 8-3/4 inches long, providing ample length for deep hole applications and ensuring stability during operation. Originally developed in the early 20th century, reamers like this one have become essential in machining and manufacturing industries. They are utilized for finishing holes to a specific diameter and improving the precision of holes that are drilled or cast. The unique spiral design enhances cutting efficiency and reduces the likelihood of tool chatter, making it ideal for high-speed machining processes. Commonly used in automotive, aerospace, and general manufacturing sectors, this tool plays a crucial role in ensuring that components fit together securely and operate with minimal friction. Its unbranded nature suggests versatility, making it compatible with various machines and setups. One of the key features of spiral taper reamers is their ability to create a slight taper that allows for better alignment with mating parts, which is critical in precision engineering applications.
