Value Collection SM220248 Straight Shell Reamer 2-3/4 in

Product Description

The VALUE COLLECTION SM220248 is a straight-flute shell reamer designed for precision bore finishing in metal fabrication and machining applications. Built from high-speed steel, it delivers consistent cutting performance across a 2.75-inch diameter with a 4-inch overall length. The right-hand cutting direction suits standard spindle rotation, and the 1.5-inch center hole accepts a No. 10 arbor for secure mounting on compatible arbor setups. Machinists and tool-and-die professionals reach for this reamer when a final pass is needed to bring a bored hole to close tolerance.

This shell reamer is suited for production and job-shop environments where large-diameter bore finishing is required. It is typically used on manual mills, boring mills, and CNC horizontal machining centers. The straight flute geometry works well with through-holes and shorter blind bores where chip clearance is not a limiting factor. Typical applications include finishing cast iron, mild steel, and non-ferrous bores to a tight size and smooth surface finish.

Key Features

• 2.75-inch reamer diameter for large-bore finishing work
• High-speed steel construction for durability across a range of workpiece materials
• Straight flute design suited to through-hole and short blind-hole applications
• Right-hand cut compatible with standard spindle rotation
• No. 10 arbor compatibility with a 1.5-inch center hole for secure arbor mounting
• 4-inch overall length provides rigid support during the finishing pass

Compatibility

Designed to mount on No. 10 arbors with a 1.5-inch center hole bore. Consult arbor manufacturer specifications to confirm fitment before use.

Installation Notes

Shell reamers are installed by a machinist or toolroom technician onto a matching arbor before mounting in the spindle. Ensure the machine spindle and workpiece are fully stopped and the work is securely fixtured before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Follow your shop's lockout/tagout procedures before any tooling setup on powered equipment.
