Value Collection 144429602490000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602490000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.2490-inch undersize diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent material removal on ferrous and non-ferrous workpieces in lathe, drill press, and CNC applications. The straight-cylindrical shank seats securely in standard chucks, and the right-hand cutting direction suits conventional clockwise spindle rotation. With a 6-inch overall length and a 1.5-inch flute length, this reamer is suited for general-purpose through-hole and shallow blind-hole finishing work.

This chucking reamer is intended for machine shop environments where close-tolerance hole finishing is required. It is classified as an undersize reamer at 0.2490 U/S, making it appropriate for applications that require a controlled interference or transition fit prior to pressing in a pin, bushing, or bearing. Machinists and toolroom technicians working in production or maintenance settings will find it applicable to light steel, aluminum, brass, and similar materials where a reamed finish is specified on the drawing.

Key Features

• 0.2490-inch finished-hole diameter — undersize designation (0.2490 U/S) for controlled-fit applications
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Straight flute geometry for smooth cutting action and easy chip clearance in through-holes
• Bright, uncoated finish — compatible with cutting oils and water-soluble coolants
• Straight-cylindrical shank for direct chuck mounting without adapters
• Right-hand cutting direction for use with standard clockwise spindle rotation

Compatibility

Designed as an OEM-style replacement or general-purpose chucking reamer for machine operations requiring a 0.2490-inch undersize reamed hole with a straight-cylindrical shank interface.

Installation Notes

Chucking reamers are installed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify runout before engaging the workpiece. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and achieve the target surface finish. Do not run a reamer in reverse, as this will damage the cutting edges.
