Value Collection SM0502100 Chucking Reamer 21mm Hss

Product Description

The VALUE COLLECTION SM0502100 is a straight-flute chucking reamer designed for precision hole finishing in metal and other machineable materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing at 21.00mm (0.8268 inches) diameter. The straight-cylindrical shank mounts securely in drill chucks and collet holders commonly found on lathes, drill presses, and milling machines. With an overall length of 9.5 inches and a 2.5-inch flute length, it provides the reach and cutting surface needed for standard through-hole and blind-hole reaming operations. Right-hand cutting direction is the standard orientation for machine-driven use.

This chucking reamer is suited for machine shop, toolroom, and general metalworking applications where a finished bore at 21.00mm is required. It is appropriate for use in CNC lathes, manual lathes, drill presses, and knee mills. The straight flute geometry performs well in materials that do not produce long, stringy chips, including cast iron, brass, and free-machining steel. Machinists and toolroom technicians are the primary installers of this tool. It is a standard stock item sold individually with no special packaging.

Installation Notes

This reamer is installed and operated by machinists and toolroom technicians. Always bring the spindle to a complete stop and confirm the machine is de-energized before inserting or removing the reamer from the chuck or collet. Secure the shank fully in the holder to the recommended grip depth before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish quality.
