Value Collection SM0407230 Chucking Reamer 0.7230 in Hss

Product Description

The VALUE COLLECTION SM0407230 is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer holds a cutting diameter of 0.7230 inches to a tight tolerance of +0.0002 to -0.0000 inches. The right-hand cutting direction and straight-cylindrical shank make it compatible with standard drill chucks and collet holders on lathes, drill presses, and machining centers. At 9 inches overall length with a 2.25-inch flute length, it is well suited for through-holes and shallow blind-hole finishing operations in general machining environments.

This chucking reamer is used in metalworking shops, maintenance and repair operations, and production machining where a close-tolerance finished bore is required. Typical applications include reaming holes in steel, cast iron, aluminum, and similar machinable materials where a drilled hole alone does not achieve the required surface finish or dimensional accuracy. The straight flute geometry is preferred for short-chipping materials and interrupted cuts.

Key Features

• Cutting diameter of 0.7230 inches held to a +0.0002 to -0.0000 inch tolerance for precise finished bores
• High-speed steel (HSS) construction provides good wear resistance across a broad range of machinable metals
• Bright, uncoated finish suitable for general-purpose reaming without added coating cost
• Straight flute geometry performs well in short-chipping materials and interrupted-cut conditions
• Straight-cylindrical shank fits standard drill chucks and collet systems
• Right-hand cutting direction for conventional forward-feed operation

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks and collet holders; suitable for lathes, drill presses, and machining centers accepting a straight-cylindrical shank in this diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists and tool-and-die professionals. Ensure the workpiece and machine spindle are secure before beginning the reaming pass, and use the appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never run a reamer in reverse, as this will damage the cutting edges. Always pre-drill or bore the hole to within a few thousandths of the finished diameter before reaming.
