Value Collection 144429601865000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429601865000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled holes to a precise diameter of 0.1865 inches. Built with a straight flute geometry and a straight-cylindrical shank, this tool mounts directly in a drill chuck or collet for reliable, repeatable sizing. It carries an overall length of 4.5 inches with a 1.125-inch flute length, making it suitable for through-holes and shallow blind holes in light to medium workpiece materials. The bright, uncoated finish is standard for general-purpose HSS reamers. This tool is intended for machinists, toolroom technicians, and maintenance professionals working on precision hole-finishing operations.

This chucking reamer is used in machine shop, maintenance, and production environments where hole tolerances require finishing beyond what a drill bit alone can achieve. It is classified as an under-size reamer at 0.1865 U/S, meaning it is ground slightly below nominal to bring interference-fit or press-fit holes to a controlled final dimension. Right-hand cutting direction suits standard CNC mills, drill presses, and manual lathes. Typical applications include finishing bores in metal components, jig and fixture work, and precision hole preparation in ferrous and non-ferrous materials.

Key Features

• 0.1865-inch finished hole diameter, classified as an under-size reamer (0.1865 U/S)
• High-speed steel (HSS) construction for cutting ferrous and non-ferrous metals
• Straight flute design provides smooth cutting action in through-hole applications
• Straight-cylindrical shank for direct chuck or collet mounting without adapters
• Bright/uncoated finish — no coating buildup that can affect finished hole size
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style replacement chucking reamer for use in drill chucks or collets accepting a straight-cylindrical shank in the 0.1500 to 0.1999-inch diameter range.

Installation Notes

This reamer is installed and operated by machinists or toolroom technicians on drill presses, lathes, or CNC machining centers. Secure the straight-cylindrical shank firmly in a chuck or collet before use and confirm there is no runout before cutting. Pre-drill the hole close to final size before reaming — do not use a chucking reamer as a primary material-removal tool. Always apply appropriate cutting fluid for the workpiece material to extend tool life and achieve the target surface finish.
