Value Collection 144429602160000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602160000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.2160-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers clean, accurate bore sizing in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks, collet chucks, and machine spindles. Six flutes provide a smooth cutting action with adequate chip clearance. Right-hand cutting direction suits conventional CNC machining centers, knee mills, drill presses, and lathes where clockwise spindle rotation is standard.

This chucking reamer is suited for machine shop, toolroom, and light production environments. It is used when a drilled hole requires tight diameter tolerance and improved surface finish that a drill bit alone cannot achieve. Typical applications include sizing holes for close-tolerance pins, bushings, and dowels in metal fabrication, repair shops, and general machining. The 0.2160-inch size falls in the 0.2000 to 0.2499-inch decimal inch range, making it a common choice for finish-reaming holes in that size class.

Key Features

• 0.2160-inch finished bore diameter for precise hole sizing
• High-speed steel (HSS) construction handles a broad range of workpiece materials
• Bright, uncoated finish maintains sharp cutting edges out of the box
• 6-flute straight configuration provides smooth cutting and controlled chip evacuation
• Straight-cylindrical shank fits standard drill chucks, ER collets, and machine spindles without adapters
• Right-hand cut matches conventional clockwise spindle rotation

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle or chuck accepting a straight-cylindrical shank in the 0.2160-inch diameter class.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians using standard machine tools. Power down and lock out the machine before changing tooling. Secure the shank fully in the chuck or collet to the manufacturer-recommended grip depth, and verify runout before cutting. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
