Value Collection 144429605120000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429605120000 is a chucking reamer designed to bring holes to precise finished dimensions in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer features an 0.5120-inch diameter cutting head and a straight-cylindrical shank for secure chuck mounting in drill presses, lathes, and CNC machining centers. Eight straight flutes provide smooth, consistent material removal and accurate hole sizing. The right-hand cutting direction suits standard spindle rotation without modification. Machinists and tool-and-die professionals reach for this reamer when tolerance and surface finish matter more than a drilled hole alone can deliver.

This chucking reamer is suited for finishing operations in ferrous and non-ferrous metals where tight hole tolerances are required. The 0.5120-inch diameter places it in the 0.5000 to 0.6999-inch range, making it a practical choice for general-purpose machine shop work, fixture building, and close-tolerance bore finishing in both job-shop and production environments. It is sold individually and is appropriate for single-use tooling setups or as a dedicated size in a reamer rack.

Key Features

• 0.5120-inch reamer diameter for precise finished-bore sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Eight straight flutes for smooth cutting action and accurate hole geometry
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank seats securely in standard drill chucks and collets
• Bright, uncoated finish — no coating delamination risk in sensitive applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a chuck or collet capable of accepting a straight-cylindrical shank in the 0.5120-inch diameter class.

Installation Notes

Chucking reamers are installed by machinists in machine tool spindles — power down and lock out the machine before changing tooling. Ensure the shank is fully seated and the chuck or collet is tightened to the machine manufacturer's specification before starting the spindle. Use cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Never run a reamer in reverse, as reverse rotation will dull the cutting edges immediately.
