Value Collection 144429603070000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603070000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3070-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in drill chucks or collet holders on lathes, drill presses, and CNC machining centers. With 6 flutes and a right-hand cutting direction, it produces smooth, tight-tolerance bores suited to production and maintenance work alike. Weight is 0.12 pounds.

This chucking reamer is used in metalworking applications where a drilled hole must be brought to a precise final diameter with a quality surface finish. Typical applications include finishing bearing bores, pin holes, and close-tolerance shaft fits in job shops, maintenance repair operations, and light manufacturing environments. It is suitable for use in manual lathes, drill presses, and CNC equipment where a straight-cylindrical shank toolholder is available.

Key Features

• 0.3070-inch finished bore diameter for precision hole sizing
• High-speed steel (HSS) construction for durability in a wide range of materials
• 6 straight flutes for smooth cutting action and consistent surface finish
• Right-hand cutting direction, standard for most lathe and drill press setups
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a drill chuck or straight-shank collet holder sized to accept the straight-cylindrical shank diameter.

Installation Notes

Chucking reamers are installed and operated by machinists and toolmakers. Power down and de-energize the machine spindle before loading or unloading the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened securely before operation. Reamers should be run at lower RPM and higher feed rates than the pilot drill to achieve the intended surface finish and dimensional tolerance — consult machining reference data for appropriate speeds and feeds for the workpiece material.
