Value Collection 144429603980000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603980000 is a chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3980-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders on lathes, drill presses, and milling machines. Six straight flutes cut on right-hand rotation, providing smooth material removal and clean hole surfaces. This reamer is intended for machinists, toolmakers, and maintenance technicians who require consistent, tight-tolerance hole sizing in production or repair work.

This chucking reamer is suited for machine-tool applications where a precise finish bore is required after drilling. The 0.3980-inch diameter falls within the 0.3500 to 0.3999-inch decimal-inch range, making it a common choice for close-tolerance fits in metal fabrication, maintenance, and repair operations. It mounts in any machine spindle that accepts a straight-cylindrical shank, including lathes, knee mills, and drill presses. The right-hand cutting direction is compatible with standard forward-rotation spindle setups found in most machine shops.

Key Features

• 0.3980-inch finished-hole diameter for precise, repeatable sizing
• High-speed steel (HSS) construction for durability across a wide range of workpiece materials
• Six straight flutes provide smooth cutting action and good chip clearance
• Right-hand cutting direction matches standard forward spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated finish suitable for general-purpose reaming applications

Compatibility

Designed as a general-purpose chucking reamer for use in any machine spindle that accepts a straight-cylindrical shank, including lathes, drill presses, and milling machines operating with standard right-hand rotation.

Installation Notes

Chucking reamers are installed and operated by machinists or qualified tool-and-die personnel. Secure the straight-cylindrical shank fully in the chuck or collet before starting the spindle. Always bring the spindle to a full stop before measuring or adjusting the workpiece. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish.
