Value Collection 144429602564000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602564000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to precise tolerances. With a 25/64 inch (0.3906 inch decimal) diameter and a 7 inch overall length, this reamer delivers accurate sizing in a range of machine-shop and maintenance applications. The straight flute geometry and bright uncoated finish make it well suited for general-purpose reaming in softer ferrous and non-ferrous materials. It is installed by machinists, tool-and-die technicians, and maintenance mechanics working with drill presses, lathes, or CNC machining centers.

This chucking reamer is used in production and job-shop environments where hole finishing to close tolerances is required. The straight-cylindrical shank allows direct mounting in standard drill chucks or collet holders. It is appropriate for through-holes and blind holes in light-to-medium stock removal operations. The 1-3/4 inch flute length accommodates typical hole depths for this diameter class, making it a practical choice for general machining, fixture work, and repair operations.

Key Features

• 25/64 inch diameter (0.3906 inch decimal) for precise hole sizing in the 0.3500 to 0.3999 inch range
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Straight-cylindrical shank for compatibility with standard drill chucks and collet holders
• Straight flute design suited for general-purpose reaming and smooth chip evacuation
• Bright/uncoated finish — no coating buildup risk on close-tolerance work
• Right-hand cutting direction for standard machine spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance mechanics. Power down and lock out the machine spindle before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to prevent slippage during the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish; never run a chucking reamer dry on steel without lubrication.
