Value Collection 144429602155000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602155000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to precise tolerances. With a cutting diameter of 0.2155 inches and six straight flutes, it produces smooth, accurate bores in ferrous and non-ferrous materials. The straight-cylindrical shank allows secure mounting in standard drill chucks, collets, or machine spindles. This tool is suited for use in drill presses, lathes, and CNC machining centers where hole sizing and surface finish are critical. Machinists and tool and die professionals reach for chucking reamers when a drilled hole must meet a tight dimensional requirement that drilling alone cannot achieve.

This reamer is appropriate for general-purpose machining applications requiring a final bore diameter of 0.2155 inches, placing it within the 0.2000 to 0.2499 inch diameter range. It is well matched to job-shop and production environments where straight-flute HSS reamers are preferred for their rigidity in short-chipping materials such as cast iron, brass, and mild steel. The straight-cylindrical shank provides broad compatibility with standard toolholding equipment without the need for specialized adapters.

Key Features

• 0.2155 inch cutting diameter for precise hole finishing
• Six straight flutes for rigidity and consistent chip clearance in short-chipping materials
• High-speed steel (HSS) construction offers good wear resistance across a range of workpiece materials
• Straight-cylindrical shank seats securely in drill chucks, ER collets, and similar toolholders
• Not configured as a dowel pin reamer or over/under size reamer — intended for standard diameter finishing

Compatibility

Designed as a standard chucking reamer for use in any machine spindle or chuck capable of accepting a straight-cylindrical shank tool at the 0.2155 inch diameter specification.

Installation Notes

Chucking reamers are installed by machinists in drill presses, lathes, or machining centers. Ensure the workpiece and machine are fully secured before operation, and confirm spindle runout is within acceptable limits to avoid oversizing the bore. Pre-drill or bore the hole to the recommended under-size before reaming, and apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
