Value Collection SM0407250 Chucking Reamer 0.7250 in Hss

Product Description

The VALUE COLLECTION SM0407250 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.7250-inch diameter in metalworking and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance on ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill chuck or collet for accurate, on-center alignment. With a 9-inch overall length and a 2.25-inch flute length, this reamer is suited for through-holes and shallow blind holes where close-tolerance sizing is required. Right-hand cutting direction is standard for conventional machine spindle rotation. Machinists, tool-and-die makers, and maintenance technicians are the primary users.

This chucking reamer is used in general machining, maintenance repair, and production environments where drilled holes must be brought to a precise final diameter. It is appropriate for use in drill presses, lathes, and milling machines with a compatible chuck or collet setup. Typical applications include sizing bearing bores, pin-fit holes, and close-tolerance through-holes in steel, cast iron, aluminum, and similar materials. The uncoated HSS construction makes it easy to resharpen with standard tool-grinding equipment when cutting edges wear.

Key Features

• 0.7250-inch reamer diameter for precise hole finishing to tight tolerances
• High-speed steel (HSS) construction provides hardness and wear resistance across a broad range of workpiece materials
• Straight flute geometry suits a wide variety of materials and reduces chatter in through-hole applications
• Bright, uncoated finish simplifies regrinding and inspection of cutting edges
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Right-hand cutting direction matches conventional machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in any drill press, lathe, or milling machine equipped with a drill chuck or collet capable of holding a straight-cylindrical shank of 0.7250 inches in diameter.

Installation Notes

Always power down and lock out the machine before installing or removing the reamer from the chuck or collet. Secure the straight-cylindrical shank with sufficient chuck jaw engagement to prevent slippage under cutting load. Use cutting fluid appropriate for the workpiece material to extend tool life and maintain hole finish quality. Pre-drill the hole to the recommended undersize before reaming to avoid overloading the flutes.
