Value Collection SM0407440 Chucking Reamer 0.744 in Hss

Product Description

The VALUE COLLECTION SM0407440 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.7440-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate bore sizing in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill chuck or collet holder, making it compatible with standard drill presses, lathes, and CNC machining centers. With a 2.5-inch flute length and a 9.5-inch overall length, it provides the reach needed for moderately deep through-holes and blind bores. Right-hand cutting direction and six flutes produce a smooth, consistent finish with each pass.

This chucking reamer is suited for machine shop and production environments where hole tolerances require finishing beyond what a drill alone can achieve. It is appropriate for use in general metalworking, tool-and-die, maintenance and repair, and light manufacturing applications. The 0.7440-inch diameter falls within the 0.7000- to 0.9999-inch decimal inch range, making it a practical choice for jobs requiring near-half-inch-plus bore finishing in steel, cast iron, aluminum, and brass workpieces.

Key Features

• 0.7440-inch finished bore diameter for precise hole sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Six straight flutes for smooth cutting action and consistent surface finish
• Bright uncoated finish suitable for use with cutting fluids standard to HSS tooling
• Straight-cylindrical shank for secure seating in chucks and collet holders
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a standard machine chucking reamer for use in drill presses, lathes, and machining centers equipped with a chuck or collet capable of accepting a straight-cylindrical shank at the 0.7440-inch diameter class.

Installation Notes

Machine chucking reamers are installed and operated by machinists following standard shop practices. Secure the straight-cylindrical shank firmly in the machine chuck or collet before use and verify runout is within acceptable limits before engaging the workpiece. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never rotate a reamer in reverse, as back-cutting will damage the flute edges.
