Value Collection 144429603115000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603115000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise under-size diameter of 0.3115 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill press chuck or lathe tailstock chuck. With a 6-inch overall length and a 1.5-inch flute length, it is well suited for through-holes and shallow blind holes in production and maintenance machining environments. Right-hand cutting direction is standard.

This reamer is intended for machinists, toolmakers, and maintenance technicians working in job shops, manufacturing facilities, and MRO settings. It is classified as an over/under-size reamer, specifically an under-size designation (0.3115 U/S), making it appropriate when a controlled interference or press fit is required and the finished hole must run slightly below nominal. It is compatible with standard drill press and lathe setups where a straight-cylindrical shank is accepted.

Key Features

• 0.3115-inch reamer diameter — under-size designation (0.3115 U/S) for controlled interference fits
• HSS tool material for durability across a broad range of workpiece materials
• Bright/uncoated finish — no coating buildup affecting dimensional tolerances
• Straight flute geometry for smooth chip evacuation in through-hole applications
• Straight-cylindrical shank for secure chuck mounting on drill presses and lathes
• Right-hand cutting direction, industry-standard orientation

Compatibility

Designed as an OEM-style chucking reamer for use in any drill press or lathe tailstock chuck accepting a straight-cylindrical shank of the corresponding diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists or skilled maintenance technicians. Before mounting, ensure the machine is powered off and the chuck is clean and free of debris. Secure the shank firmly in the chuck and verify runout before cutting. Use appropriate cutting fluid for the workpiece material, and never reverse the reamer rotation while it is engaged in the hole, as this can damage the cutting edges.
