Value Collection SM0500550 Chucking Reamer 5.50mm Hss

Product Description

The VALUE COLLECTION SM0500550 is a straight-flute chucking reamer designed to finish-ream drilled holes to a precise 5.50mm (0.2165 inch) diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bores in a wide range of ferrous and non-ferrous workpiece materials. The straight-cylindrical shank seats securely in standard drill chucks and collets, making it a practical choice for machine shop, tool room, and production floor use. With an overall length of 5 inches and a six-flute geometry, it provides stable cutting action and good chip clearance on through-holes and blind holes alike.

This reamer is suited for general-purpose machine reaming operations where close-tolerance hole finishing is required. It is intended for use in drill presses, CNC machining centers, lathes, and manual milling machines. The right-hand cutting direction is compatible with standard spindle rotation. Typical applications include reaming pilot holes, bearing bores, and dowel-pin fits in light manufacturing and maintenance machining environments. The compact flute length of 1-1/4 inches keeps the cutting zone stiff and minimizes deflection in shallow reaming passes.

Key Features

• 5.50mm (0.2165 inch) reamer diameter for precise hole finishing
• High-speed steel (HSS) construction provides durability across a range of workpiece materials
• Six straight flutes with right-hand cutting direction for smooth, consistent stock removal
• Bright, uncoated finish reduces built-up edge on non-ferrous materials
• Straight-cylindrical shank fits standard drill chucks and collets without an adapter
• 5-inch overall length with 1-1/4-inch flute length keeps the tool rigid during light passes

Compatibility

Designed as a general-purpose chucking reamer compatible with any machine spindle equipped with a drill chuck or collet sized to accept a straight-cylindrical shank in the 5.50mm diameter class.

Installation Notes

Chucking reamers are installed and removed by a qualified machinist with the machine spindle fully stopped and locked out per applicable safety procedures. Secure the shank firmly in a drill chuck or collet before operation to prevent runout. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never attempt to ream a hole that has not been pre-drilled or bored to the correct undersize diameter.
