Value Collection ST0110028 Chucking Reamer 7/16 in Hss

Product Description

The VALUE COLLECTION ST0110028 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 7/16 inch (0.4375 inch) diameter. It features a straight-flute, 6-flute geometry with a right-hand cutting direction, delivering smooth material removal and accurate sizing in metal machining applications. The Morse taper shank (1MT) seats directly into compatible taper-socket spindles on drill presses, lathes, and milling machines. The bright, uncoated HSS construction handles general-purpose reaming on steel, cast iron, aluminum, and similar materials. Overall length is 7 inches with a 1-3/4 inch flute length, and the tool weighs approximately 0.18 pounds.

This chucking reamer is suited for machine shop, maintenance, and production environments where a clean, finished bore at 0.4375 inch is required. It is a standard tool for licensed machinists and tool-and-die tradespeople working on fixtures, shafts, bushings, and mechanical assemblies. The 1MT shank makes it straightforward to mount on bench-top drill presses and engine lathes equipped with a No. 1 Morse taper socket, without requiring an additional adapter in most cases.

Key Features

• 7/16 inch (0.4375 inch) reamer diameter for precise hole finishing
• 6 straight flutes with right-hand cutting direction for smooth, consistent material removal
• No. 1 Morse taper (1MT) shank for direct mounting in compatible taper-socket spindles
• High-speed steel (HSS) construction handles general-purpose machining on ferrous and non-ferrous materials
• Bright, uncoated finish — no coating buildup to affect dimensional tolerance
• Compact 1-3/4 inch flute length suits shallow to moderate bore depths

Compatibility

Designed as a standard 1MT shank chucking reamer for use in drill presses, lathes, and milling machines equipped with a No. 1 Morse taper socket.

Installation Notes

Chucking reamers are installed by machinists on powered machine tools — always power down and lock out the spindle before seating or removing the taper shank. Clean the taper socket and shank of chips and oil before seating to ensure full contact and prevent runout. Use cutting fluid appropriate for the workpiece material during reaming to extend tool life and improve bore finish. Do not use a chucking reamer as a hand reamer or apply side-load forces that could spring the flutes.
