Value Collection SM0405250 Chucking Reamer 0.5250 in Hss

Product Description

The VALUE COLLECTION SM0405250 is a straight-flute chucking reamer designed to finish-ream pre-drilled holes to a precise 0.5250-inch diameter. Made from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bores in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill chuck or collet, and the right-hand cutting direction suits standard spindle rotation. With an overall length of 8 inches and a 2-inch flute length, this reamer is well-suited for general-purpose machine-shop and maintenance work where dimensional accuracy and surface finish are critical.

This chucking reamer is intended for use in drill presses, lathes, CNC machining centers, and manual milling machines wherever a finish-reamed hole is required. It is a practical choice for tool-and-die, maintenance-repair-operations (MRO), and production environments that require consistent hole sizing in the 0.5000 to 0.6999-inch diameter range. The straight flute geometry works reliably on through-holes and shallow blind holes across most common workpiece materials.

Key Features

• 0.5250-inch finished-hole diameter for precise dimensional control
• High-speed steel (HSS) construction provides good wear resistance across common metals
• Straight flute geometry suits through-holes and shallow blind holes
• Bright, uncoated finish — ready to use out of the package, re-sharpenable
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction matches standard machine spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and machining centers that accept a straight-cylindrical shank toolholder or drill chuck sized for 0.5250-inch diameter reamers.

Installation Notes

A licensed machinist or experienced tooling technician should secure the shank firmly in a precision chuck or collet before operation, ensuring minimal runout to protect hole geometry. The workpiece must be rigidly fixtured, and the hole should be pre-drilled or bored to within accepted reaming stock allowance before the reamer is used. Cutting fluid appropriate to the workpiece material is recommended to extend tool life and improve surface finish. Do not reverse spindle rotation during a cut, as reversing direction on a right-hand reamer will damage the cutting edges.
