Value Collection 144429603930000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603930000 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing and smooth bore quality in ferrous and non-ferrous materials. It measures 0.3930 inches in diameter and features a straight-cylindrical shank for secure seating in standard drill chucks and collet holders. With 6 flutes and a right-hand cutting direction, it provides controlled material removal and reduced chatter during through-hole and blind-hole finishing operations. Machinists and tool-and-die professionals reach for this type of reamer when tolerances are tight and surface finish matters.

This chucking reamer is suited for use in manual mills, drill presses, CNC lathes, and machining centers where hole diameters in the 0.3500 to 0.3999 inch range require finishing to close tolerance. It is a general-purpose tool appropriate for job shops, maintenance departments, and production environments working with steel, aluminum, brass, and similar machinable materials. The straight flute geometry makes it well-suited for interrupted cuts and through-holes where chip evacuation is straightforward.

Key Features

• 0.3930 inch finished hole diameter for precision bore sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 6 straight flutes for controlled cutting action and consistent surface finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Bright uncoated finish suitable for general-purpose machining without specialized coolant requirements

Compatibility

Designed as a general-purpose chucking reamer for machines accepting straight-cylindrical shank tooling, covering finished hole diameters in the 0.3500 to 0.3999 inch decimal inch range.

Installation Notes

A licensed machinist or qualified tool operator should install and run this reamer. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet before operation, and verify runout is within acceptable limits for the application. Always reduce spindle speed relative to drilling and apply appropriate cutting fluid to extend tool life and improve finish quality. Inspect the reamer for chipping or wear before each use, as a damaged reamer can compromise hole tolerance.
