Value Collection 144429604000000 Chucking Reamer 0.4000 in Hss

Product Description

The VALUE COLLECTION 144429604000000 is a chucking reamer designed to finish-ream drilled or bored holes to a precise diameter of 0.4000 inches. Manufactured from high-speed steel (HSS), it delivers the hardness and wear resistance needed for production and job-shop reaming in metals including mild steel, aluminum, and cast iron. The bright, uncoated finish suits general-purpose applications where coating is not required. With 6 straight flutes and a right-hand cutting direction, this reamer produces smooth, accurate bores when driven by a drill press, lathe, or CNC machine. Machinists, tool-and-die makers, and maintenance technicians are the primary users.

This chucking reamer is suited for finishing through-holes and blind holes to close tolerances in both production and maintenance settings. The straight-cylindrical shank seats directly into a drill chuck or collet without the need for a taper adapter, making it straightforward to set up on a drill press, lathe tailstock, or machining center. It is appropriate for residential shop, commercial machine shop, and industrial maintenance applications where a 0.4000-inch finished bore diameter is required.

Key Features

• 0.4000-inch finished bore diameter for precise hole sizing
• HSS construction provides hardness and wear resistance for general-purpose metal cutting
• 6 straight flutes for smooth cutting action and efficient chip clearance
• Right-hand cutting direction compatible with standard spindle rotation
• Straight-cylindrical shank accepts standard drill chucks and collets with no adapter required
• Bright, uncoated finish suitable for general-purpose reaming applications

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and machining centers equipped with a standard drill chuck or collet capable of holding a straight-cylindrical shank in the 0.4000-inch to 0.4999-inch diameter range.

Installation Notes

Machinists and maintenance technicians should power down and lock out the machine spindle before installing or removing the reamer from the chuck or collet. Secure the straight-cylindrical shank firmly to prevent slippage during operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always ream to final size from a pre-drilled pilot hole that leaves only the recommended stock for reaming.
