Value Collection 144429600021000 Chucking Reamer 21 Hss

Product Description

The VALUE COLLECTION 144429600021000 is a straight-flute chucking reamer in wire size 21, designed to finish-ream holes to a precise 0.1590-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable cutting performance in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard machine chucks, making it suitable for drill press, lathe, and CNC operations. With a 4.5-inch overall length and a 1.125-inch flute length, the tool is sized for short to medium-depth through-holes. Right-hand cutting direction aligns with standard spindle rotation. Machinists and tool-and-die professionals use this reamer where tight hole tolerances are required.

This chucking reamer is suited to machine-shop, maintenance, and light production environments where wire-gauge hole sizing is needed. The 0.1590-inch cutting diameter falls within the 0.1500 to 0.1999-inch decimal range, making it appropriate for sizing holes to accept wire size 21 pins, shafts, or dowels. It is intended for machine use rather than hand reaming, and the straight-cylindrical shank allows quick changeover in keyed or keyless chucks. Typical applications include precision hole finishing in steel, aluminum, brass, and similar materials.

Key Features

• Wire size 21 diameter — 0.1590 inches decimal equivalent for precise hole finishing
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous workpieces
• Straight flute geometry for smooth chip evacuation in through-hole reaming
• Bright uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank for secure seating in standard machine chucks
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style machine chucking reamer suitable for use in drill presses, lathes, and CNC machining centers equipped with a standard keyed or keyless chuck that accepts a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine-shop safety procedures. Secure the straight-cylindrical shank firmly in the machine chuck before operation and confirm the spindle is at a full stop before making any tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Follow applicable shop safety codes and machine manufacturer guidelines when setting spindle speed and feed rate.
