Value Collection 144429602532000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602532000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to precise tolerances. With a 25/32-inch (0.7812 inch decimal) cutting diameter and a 9-1/2-inch overall length, this reamer delivers accurate, smooth bores in ferrous and non-ferrous workpieces. The bright, uncoated HSS construction provides reliable performance across a range of general-purpose machining applications. Machinists and toolroom technicians install this reamer in drill presses, lathes, or CNC machining centers equipped with a standard chuck or collet holder.

This chucking reamer suits production and maintenance machining environments where hole diameter accuracy and surface finish are required after drilling. The straight-cylindrical shank allows secure mounting in any standard drill chuck or collet, making it well-suited for vertical drill presses, turret lathes, and manual or CNC milling machines. The straight-flute geometry and right-hand cutting direction make it a practical choice for through-holes and blind holes in mild steel, aluminum, brass, and similar materials where chip clearance is manageable.

Key Features

• 25/32-inch diameter (0.7812 inch decimal) for accurate finish reaming within the 0.7000 to 0.9999 inch diameter range class
• High-speed steel (HSS) construction provides hardness and wear resistance for general-purpose machining
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Straight flute design with right-hand cut suits through-holes and blind holes in common metals
• Bright, uncoated finish — no coating buildup to affect diameter tolerance
• 2-1/2-inch flute length accommodates typical hole depths for this diameter class

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a chuck or collet capable of accepting a straight-cylindrical shank in the 25/32-inch diameter class.

Installation Notes

Chucking reamers are installed and operated by machinists familiar with machine tool setup and cutting tool procedures. Power down and lock out the machine before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to minimize runout, as excessive runout will degrade hole tolerance and tool life. Always pre-drill the hole to within recommended stock allowance before reaming — do not use a chucking reamer as a primary hole-making tool.
