Value Collection ST0120056 Chucking Reamer 7/8 in Hss

Product Description

The VALUE COLLECTION ST0120056 is a chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing and surface finish in ferrous and non-ferrous materials. It features a 7/8 inch (0.8750 inch decimal) cutting diameter, an overall length of 10 inches, and a 2-5/8 inch straight flute length. The Morse taper shank - specifically a 2MT designation - seats directly into compatible lathe tailstocks, drill presses, or milling machine spindles. Eight right-hand flutes provide smooth chip evacuation and a fine finish on the reamed bore. Machinists and tool-and-die professionals are the primary users of this tool.

This chucking reamer is suited for production and maintenance machining environments where final bore sizing to 7/8 inch is required. Typical applications include finishing drilled or bored holes in fixtures, mechanical components, and assemblies where tight tolerances and smooth bore walls are critical. The 2MT Morse taper shank makes it compatible with a wide range of standard machine tool spindles found in job shops, maintenance facilities, and manufacturing operations. It is intended for right-hand cutting rotation and is not configured for over- or under-size boring or dowel pin applications.

Key Features

• 7/8 inch (0.8750 inch) cutting diameter for precise bore sizing
• High-speed steel (HSS) construction for durability in general machining
• 8 straight flutes with right-hand cutting direction for smooth finish
• 2MT Morse taper shank for direct mounting in compatible spindles
• Bright, uncoated finish suitable for use with standard cutting fluids
• 10 inch overall length with 2-5/8 inch flute length

Compatibility

Designed as a standard chucking reamer for use in lathes, drill presses, and milling machines equipped with a No. 2 Morse taper (2MT) spindle or tailstock socket.

Installation Notes

This reamer is installed and operated by machinists in a machine tool environment - always power down and lock out the spindle before seating or removing the Morse taper shank. Ensure the taper socket is clean and free of chips or oil before inserting the shank to prevent runout. Use an appropriate cutting fluid for the workpiece material to extend tool life and achieve the specified bore finish. Do not use this tool for hand reaming; it is designed for machine use only.
