Value Collection 144429604010000 Chucking Reamer 0.4010 in Hss

Product Description

The VALUE COLLECTION 144429604010000 is a chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and smooth bore surfaces in drilled or bored holes. The straight-flute design with six flutes provides stable cutting action and clean chip evacuation on through-holes and blind holes alike. The straight-cylindrical shank mounts directly in a drill chuck or collet holder. This reamer is intended for use by machinists and tool-and-die professionals requiring tight dimensional tolerances in production or maintenance environments.

This reamer is suited for finishing holes to a 0.4010-inch diameter in ferrous and non-ferrous materials. It is commonly used in manual milling machines, drill presses, and CNC machining centers where a drill chuck or straight-shank collet is the workholding method. Typical applications include bearing fits, pin holes, and bushing bores requiring a precise finished diameter. The right-hand cutting direction is standard for conventional clockwise spindle rotation.

Key Features

• 0.4010-inch reaming diameter for precise hole finishing within the 0.4000 to 0.4999-inch decimal inch range
• High-speed steel (HSS) construction provides hardness and wear resistance across a broad range of workpiece materials
• Six straight flutes for stable cutting geometry and efficient chip removal
• Straight-cylindrical shank for direct chucking in standard drill chucks or straight-shank collets
• Bright, uncoated finish suitable for general-purpose reaming without coating-related dimensional offsets
• Right-hand cut matches standard clockwise machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a drill chuck or straight-shank collet capable of accepting the straight-cylindrical shank diameter of this tool.

Installation Notes

Chucking reamers are installed and removed by a qualified machinist with the machine spindle fully stopped and locked out per shop lockout/tagout procedures. Ensure the shank seats fully and is clamped securely in the chuck or collet before operation. Always pre-drill or bore the hole close to finished size, leaving only a small amount of stock for the reamer to remove. Do not run a reamer in reverse, as this will damage the cutting edges.
