Value Collection 144429604385000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604385000 is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in a wide range of ferrous and non-ferrous workpiece materials. The reamer measures 0.4385 inches in diameter and 7 inches overall length, with a 1.75-inch flute length and a straight-cylindrical shank for direct chuck mounting. It is designated as an over-size reamer at 0.4385 O/S, making it suited for applications requiring a slightly enlarged finished bore. Right-hand cutting direction follows standard reaming convention.

This chucking reamer is used in machine shop and maintenance environments where precise hole sizing is required after drilling or boring operations. It mounts in a drill press, lathe, or CNC machining center via a standard chuck. The straight-cylindrical shank allows secure clamping without requiring a tapered adapter. Typical applications include sizing holes for close-tolerance pin fits, bushing installations, and similar precision work across light manufacturing, toolroom, and MRO settings.

Key Features

• HSS construction provides good wear resistance and toughness across common workpiece materials
• Bright, uncoated finish reduces initial cost while maintaining acceptable surface finish in standard applications
• Straight flute geometry suits through-hole and short blind-hole reaming
• Over-size designation (0.4385 O/S) targets applications requiring a bore slightly above nominal 0.4375 inches (7/16 inches)
• Straight-cylindrical shank allows direct chuck mounting without adapters
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a chuck capable of accepting a straight-cylindrical shank. Suited for applications within the 0.4000 to 0.4999 inch reamer diameter range.

Installation Notes

A licensed machinist or toolroom technician should verify spindle speed and feed rate against published HSS reaming guidelines for the workpiece material before use. Secure the shank fully in the chuck and confirm runout is within acceptable limits before cutting. Always use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Power down and lock out the machine before changing or inspecting the reamer.
