Value Collection SM0407540 Chucking Reamer 0.754 in Hss

Product Description

The VALUE COLLECTION SM0407540 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.7540-inch diameter. Built with 6 straight flutes and a bright, uncoated finish, it delivers accurate hole sizing in ferrous and non-ferrous materials across machining and fabrication environments. The straight-cylindrical shank seats directly into standard drill press chucks, CNC collets, or lathe tailstock chucks. At 9.5 inches overall length with a 2.5-inch flute length, this reamer suits through-hole and moderate-depth blind-hole applications where tight dimensional tolerances are required.

This chucking reamer is suited for machine shop, toolroom, and production floor use. It is appropriate for sizing holes in fixtures, bearing bores, bushings, and general mechanical assemblies where a clean, close-tolerance finish is needed. Right-hand cutting direction makes it compatible with standard spindle rotation on drill presses, milling machines, and lathes. It fits within the 0.7000 to 0.9999 inch decimal inch reamer diameter range, making it a common choice for mid-range bore sizing work.

Key Features

• 0.7540-inch finished bore diameter for precision hole sizing
• HSS construction provides durability across a range of common workpiece materials
• 6 straight flutes for smooth, consistent material removal
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank fits standard chucks and collets without adapters
• Right-hand cutting direction matches standard machine spindle rotation

Compatibility

Designed as a machine chucking reamer for use in drill presses, lathes, and milling machines equipped with standard chucks or collets accepting a straight-cylindrical shank in the 0.7000 to 0.9999 inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists and toolroom technicians. Secure the straight-cylindrical shank firmly in the chuck or collet and verify runout before cutting. Always apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Do not use this reamer for initial stock removal — pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
