Value Collection 144429601270000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429601270000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.1270-inch diameter. Straight flutes and a bright, uncoated surface make this reamer well suited for softer ferrous and non-ferrous materials where chip flow is straightforward. The straight-cylindrical shank seats cleanly in standard drill chucks or collet holders on lathes, drill presses, and CNC machining centers. With six flutes and a right-hand cutting direction, the tool produces smooth bore surfaces and holds tight dimensional tolerances. Machinists, toolmakers, and maintenance technicians install this reamer as a finishing step after rough drilling.

This reamer covers the 0.1000 to 0.1499 inch diameter range class and is a solid choice for production and repair applications requiring a finished 0.1270-inch bore. Typical use cases include reaming precision pin-hole locations, bearing bores, and close-tolerance clearance holes in light manufacturing and maintenance environments. It is equally at home in a manual lathe tailstock setup or a CNC turret. The standard straight-cylindrical shank makes it compatible with a wide variety of common workholding setups already on the shop floor.

Key Features

• 0.1270-inch finished bore diameter with straight-cylindrical shank for broad chuck compatibility
• HSS construction provides good toughness and regrindability compared to carbide
• Six-flute geometry improves surface finish and distributes cutting load evenly
• Right-hand cutting direction — standard for conventional reaming operations
• Bright, uncoated finish suitable for use with standard cutting fluids on most common materials
• Not configured as a dowel-pin or over/under-size reamer — nominal sizing only

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, and CNC machining centers equipped with a drill chuck or collet system accepting a straight-cylindrical shank.

Installation Notes

This reamer should be installed by a qualified machinist or toolroom technician. Always secure the workpiece and confirm the shank is fully seated and properly clamped before starting the spindle. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use a chucking reamer to remove excessive stock — pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
