Value Collection 144429603090000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603090000 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.3090 inch diameter. Manufactured from high-speed steel (HSS), it delivers the hardness and wear resistance needed for accurate sizing in ferrous and non-ferrous metals. The straight-cylindrical shank mounts directly in a drill chuck or collet holder on a drill press, lathe, or CNC machining center. With 6 straight flutes, the tool produces clean, consistent bore walls and evacuates chips efficiently during through-hole and blind-hole finishing operations. It is a solid-body reamer intended for standard-size holes, not over- or under-size applications.

This chucking reamer is suited for machine shop, maintenance, and production environments where hole tolerance and surface finish are critical. Typical applications include finishing drilled or bored holes in steel, cast iron, aluminum, brass, and similar materials. The 0.3090 inch diameter falls within the 0.3000 to 0.3499 inch decimal inch range, making it a go-to tool for precision hole sizing in fixtures, housings, and mechanical assemblies. It is intended for use by machinists, tool and die makers, and maintenance mechanics working on manual or CNC equipment.

Key Features

• 0.3090 inch finished-hole diameter for precise bore sizing
• HSS construction provides hardness and heat resistance for general-purpose machining
• 6 straight flutes deliver clean walls and efficient chip clearance
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Standard-size reamer — not configured for over- or under-size applications
• Lightweight at 0.11 pounds, suitable for bench or machine use

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a standard chuck or collet that accepts a straight-cylindrical shank.

Installation Notes

A licensed machinist or trained operator should install this reamer in a properly sized collet or drill chuck, ensuring the shank is fully seated and the runout is within acceptable limits before operation. Power down and de-energize the machine before changing tooling. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not exceed the recommended feed and speed parameters for HSS tooling in the material being machined.
