Value Collection 144429603410000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603410000 is a chucking reamer designed for precision hole finishing in metal and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers a 0.3410-inch cutting diameter and features six straight flutes with a right-hand cutting direction. It is used to bring drilled or bored holes to a precise final diameter, producing a clean, smooth bore wall. The straight-cylindrical shank seats directly into standard drill chucks or collet holders, making setup straightforward for machinists and tool-and-die professionals working in production or maintenance environments.

This chucking reamer is suited for general-purpose reaming operations across job shop, maintenance, and light manufacturing settings. The 0.3410-inch diameter falls within the 0.3000 to 0.3499 inch decimal inch reamer diameter range, making it a practical choice for through-holes and blind holes that require tight dimensional tolerances. It is not configured as a dowel pin reamer and is not an over or under-size reamer, so it is intended for standard on-size finishing cuts rather than interference or clearance fits.

Key Features

• 0.3410-inch cutting diameter for precise hole finishing to a defined nominal size
• HSS construction provides good wear resistance and toughness across a range of workpiece materials
• Six straight flutes for smooth cutting action and efficient chip evacuation
• Right-hand cutting direction compatible with standard clockwise spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Bright, uncoated finish suitable for use with cutting fluids in general-purpose applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with a compatible chuck or collet system accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists or tool-and-die technicians. Ensure the machine spindle is fully stopped and the chuck is locked securely before inserting or removing the reamer. Always use an appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality. Do not use a reamer to remove excessive stock — drilling to within a few thousandths of the finished diameter before reaming is standard practice.
