Value Collection ST0220044 Chucking Reamer 11/16 in Hss

Product Description

The VALUE COLLECTION ST0220044 is an 8-flute high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal and other machinable materials. With a diameter of 0.6875 inches (11/16 inches) and a 2 Morse Taper (2MT) shank, this reamer mounts directly to compatible taper-socket machines and drill presses without an additional adapter. The 9-inch overall length and 2.25-inch spiral flute section provide stable cutting geometry and efficient chip evacuation. The bright, uncoated HSS construction suits general-purpose reaming where high surface speeds or exotic alloys are not a concern.

This chucking reamer is suited for machine shop, maintenance, and production environments where bored or drilled holes require final sizing to close tolerance. The right-hand spiral flute configuration and right-hand cutting direction are standard for use with conventional drill press or lathe tailstock setups. Typical applications include finishing holes in ferrous metals, aluminum, brass, and plastics. It is packaged individually, making it a practical single-replacement purchase for tool cribs or job-site kits.

Key Features

• 11/16 inches (0.6875 inches decimal) diameter for precise hole sizing
• 8-flute spiral design promotes smooth cutting action and efficient chip removal
• 2 Morse Taper (2MT) shank for direct mounting in compatible machine spindles
• Right-hand spiral flutes with right-hand cutting direction — standard machine-room configuration
• Bright/uncoated HSS construction — suitable for general-purpose reaming across common metals and plastics
• 9-inch overall length with 2.25-inch flute length for controlled material removal

Compatibility

Designed as an OEM-style replacement or stock chucking reamer for machine tools equipped with a No. 2 Morse Taper socket, including drill presses, lathes, and milling machine tailstocks.

Installation Notes

Chucking reamers are installed and operated by machinists and tool-room technicians. Power down and de-energize the machine spindle completely before mounting or removing the reamer from the taper socket. Ensure the taper socket and shank are clean and free of chips or burrs before seating to prevent runout. Always operate at the feed rate and spindle speed appropriate for the workpiece material — consult published HSS cutting data for the specific alloy being reamed.
