Value Collection SM0406720 Chucking Reamer Hss 0.6720 in

Product Description

The VALUE COLLECTION SM0406720 is a straight-flute chucking reamer designed to bring finish-bored or drilled holes to a precise 0.6720-inch diameter. Made from high-speed steel (HSS) with a bright, uncoated finish, it provides the hardness and edge retention needed for controlled material removal in ferrous and non-ferrous workpieces. The straight-cylindrical shank seats directly in a drill chuck or collet chuck on a drill press, lathe, or CNC machining center. At 9 inches overall length with a 2.25-inch flute length, it handles moderate-depth through-holes and blind holes common in general machining and maintenance work. Machinists and toolroom technicians typically install and run this reamer as the final sizing step before press-fitting bushings, dowel pins, or precision pins.

This reamer suits general-purpose machine shop and maintenance machining applications where a 0.6720-inch finished bore is required. It is well matched to drill press, turret lathe, and knee-mill setups where a straight-cylindrical shank is preferred. The right-hand cutting direction is standard for conventional forward-feed reaming operations. Typical use cases include hole sizing for locating pins, bearing bores, and fixture bushings in both production and one-off repair scenarios.

Key Features

• 0.6720-inch finished bore diameter for precision hole sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Straight flute geometry suited to through-holes and shallow blind holes
• Bright, uncoated finish — ready to use out of the package, no additional prep required
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Right-hand cutting direction for conventional forward-feed reaming

Compatibility

Designed as a standard chucking reamer for use in any machine tool accepting a straight-cylindrical shank — including drill presses, lathes, and milling machines — where a 0.6720-inch finished diameter is required.

Installation Notes

A licensed machinist or qualified toolroom technician should set up and operate this reamer. Always pre-drill or bore the hole to the correct undersize before reaming — attempting to remove excessive stock with a reamer will shorten tool life and degrade hole finish. Secure the shank firmly in a chuck or collet and verify runout before taking a reaming pass. Use an appropriate cutting fluid for the workpiece material to improve finish and extend cutting edge life.
