Value Collection SM2200356 Straight Shell Reamer 3-7/8 in

Product Description

The VALUE COLLECTION SM2200356 is a straight-flute shell reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel, it delivers consistent material removal and accurate bore sizing in production and job-shop environments. The reamer measures 3.875 inches in diameter with a 5-inch overall length and accepts a No. 12 arbor through a 2-inch center hole. Right-hand cutting direction makes it compatible with standard spindle rotation on mills, lathes, and dedicated reaming machines. Machinists and tool-and-die technicians install this type of reamer as the final pass to achieve tight dimensional tolerances and smooth bore finishes.

This shell reamer is suited for medium-to-large bore finishing operations in manufacturing, maintenance, and repair environments. The 3.875-inch cutting diameter addresses bore sizes common in heavy equipment components, large fixtures, and industrial assemblies. The straight flute geometry works well in materials that produce short, breaking chips and where rigidity in the cut is prioritized. A licensed machinist or CNC operator would typically mount this reamer on an arbor press, horizontal mill, or lathe for finish-reaming pre-drilled or bored holes to final specification.

Key Features

• 3.875-inch reamer diameter for large-bore finish work
• 5-inch overall length provides stable reach in the cut
• High-speed steel construction handles a wide range of ferrous and non-ferrous workpiece materials
• Straight flute design suits through-bore applications with favorable chip evacuation conditions
• No. 12 arbor compatibility with 2-inch center hole for secure, concentric mounting
• Right-hand cutting direction matches standard machine spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling option for No. 12 arbor setups used in large-bore shell reaming operations on mills, lathes, and reaming fixtures.

Installation Notes

Shell reamers are installed by machinists and toolroom technicians. Always mount the reamer securely on the correct arbor size before use and verify runout with a dial indicator prior to cutting. Power down and lock out the machine spindle before changing tooling. Do not use a shell reamer as a primary material-removal tool — it is intended as a finishing pass on a pre-bored or pre-drilled hole held close to final size.
