Value Collection 144429604300000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604300000 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.4300-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable cutting performance on a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats directly into drill chucks, collet chucks, or machine spindles without requiring a taper adapter. Eight flutes distribute cutting load evenly, producing smooth bore finishes and consistent dimensional accuracy. This reamer is intended for use by machinists and tool-and-die professionals working on CNC machining centers, manual lathes, or drill presses.

This chucking reamer is suited for production and job-shop environments where tight hole tolerances are required after drilling. It handles through-hole and blind-hole applications in materials including mild steel, aluminum, brass, and cast iron. Right-hand cutting direction is standard for conventional machine spindle rotation. The 0.4300-inch diameter falls within the 0.4000 to 0.4999 inch reamer diameter range, making it a practical choice when a standard 7/16-inch reamer does not meet the required finish dimension.

Key Features

• 0.4300-inch finished bore diameter for tight-tolerance hole sizing
• 8-flute straight configuration for smooth surface finish and even chip load
• HSS construction provides good toughness and wear resistance across common workpiece materials
• Straight-cylindrical shank fits standard drill chucks and collet systems without adapters
• Right-hand cutting direction matches conventional machine spindle rotation
• Bright uncoated finish — no coating buildup to affect dimensional tolerance

Compatibility

Designed as a standard chucking reamer for use in drill chucks, collet chucks, and machine spindles accepting a straight-cylindrical shank at 0.4300-inch finished diameter.

Installation Notes

A licensed machinist or trained operator should install this reamer in a properly trammed and secured machine spindle before use. Ensure the workpiece is firmly clamped and the machine is at a safe, reduced RPM appropriate for reaming — reaming feeds and speeds are significantly lower than drilling. Apply cutting fluid suited to the workpiece material to extend tool life and improve surface finish. Never use a reamer to remove excessive stock; pre-drill or bore the hole close to final size before reaming.
