Value Collection 144429602500000 Chucking Reamer Letter Y

Product Description

The VALUE COLLECTION 144429602500000 is a straight-flute chucking reamer sized to Letter Y, equivalent to 0.4040 inches in diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers precise hole finishing in a wide range of ferrous and non-ferrous materials. It features a straight-cylindrical shank for secure gripping in standard chucks, a 1.75-inch flute length, and a 7-inch overall length. The right-hand cutting direction suits conventional drilling setups. Machinists and tool-and-die professionals reach for this reamer when they need reliable, repeatable bore sizing in production or maintenance environments.

This chucking reamer is suited for use in drill presses, lathes, and milling machines where consistent hole tolerance and surface finish are required. The Letter Y designation targets holes in the 0.4000 to 0.4999-inch diameter range, making it a practical choice for pin fits, dowel holes, and precision bore finishing on machined components across general manufacturing, repair, and fabrication shops.

Compatibility

Designed as a standard chucking reamer for use in any machine tool accepting a straight-cylindrical shank in this diameter class, including drill presses, engine lathes, and vertical mills.

Installation Notes

A licensed machinist or qualified toolroom technician should verify spindle speed and feed rate against standard HSS reamer recommendations for the workpiece material before use. Always secure the shank fully in the chuck or collet and confirm runout is within acceptable tolerance before cutting. Apply appropriate cutting fluid to extend tool life and improve bore finish. Inspect the reamer for chipping or wear before each use and do not force the tool through an undersized pilot hole.
