Specifications for a .375 Reamer

A reamer is a rotary tool bit that is used for a variety of applications. A .375 reamer is generally associated with modifying iron head golf clubs, cutting valves and boring holes. The reamer is also used for widening valves and cylinders or tapering the hosels on the clubs to a specific degree. To use the .375 reamer effectively, you should familiarize yourself with its specifications.

  1. Use

    • The .375 reamer is typically used as a chucking bit, fit into a drill chuck. Most commonly used for tapering iron hosel bores to parallel, or enlarging parallel hosel bores. The .375 reamer can also be made to fit into a drill press for precisely cutting valves or boring holes, though it is much easier to manipulate while installed in a hand-held drill chuck.

    Style

    • The .375 diameter reamer is a straight, flute style, chuck held shank. These reamers can be made of several alloys, depending on what cutting use is intended. Such allows include carbide steel, diamond coated and stainless steel. .375 reamers can range typically from three to eight cutting edges, depending on the manufacturer of the reamer.

    Cutting

    • The .375 reamer is typically operated in a drill that cycles at least 500 RPMs for most machine work. Machine shops often employ drills and rotary tools that cycle at much higher RPMs, and reamers used in these shops are made from material that allows cutting at such high speeds. The reamer is often used with cutting oil to reduce friction on both large and small jobs.

    Length and Weight

    • All .375 reamers have the same diameter cutting edge, though they can be made in several lengths. Common length of the reamer is generally 5 to 7 inches long, though larger reamers for industrial use can be as long as 20 inches or more. The bits vary in weight depending on the type of material from which they are fabricated. Common drill-chuck reamers generally weight between 0.4 and 0.8 ounces, but they can weigh several pounds if used in industrial machinery.
