Value Collection SM2300124 Spiral Shell Reamer 1-3/8 in

Product Description

The VALUE COLLECTION SM2300124 is a spiral shell reamer designed for precision hole finishing in metalworking applications. This right-hand cut reamer features a left-hand spiral flute configuration and is manufactured from high-speed steel, providing durability under the heat and pressure of reaming operations. With a 1.375-inch reaming diameter and a 3-inch overall length, this tool is sized for moderate bore finishing tasks where dimensional accuracy and surface finish are the primary objectives. It is installed on a No. 7 arbor and includes a 0.75-inch center hole. Machinists, toolroom operators, and maintenance technicians working with manual or CNC machinery are the primary users.

This spiral shell reamer is suited for finishing pre-drilled or bored holes to a precise 1.375-inch diameter in ferrous and non-ferrous metals. The spiral flute geometry promotes smooth chip evacuation and reduces chatter compared to straight-flute designs, making it a practical choice for through-hole and blind-hole applications in production machining, repair shops, and tool rooms. The right-hand cutting direction combined with the left-hand spiral helps draw chips away from the finished surface during operation.

Key Features

• 1.375-inch reaming diameter for precision bore finishing
• High-speed steel construction for heat and wear resistance
• Left-hand spiral flute promotes effective chip evacuation
• Right-hand cutting direction for standard machine spindle use
• No. 7 arbor compatibility with a 0.75-inch center hole
• Compact 3-inch overall length suits bench and knee mill setups

Compatibility

Designed for use with No. 7 arbor holders. Fits standard shell reamer arbors accepting a 0.75-inch center hole. Verify arbor taper and drive slot dimensions before installation.

Installation Notes

Shell reamers are installed and removed by a qualified machinist or toolroom technician. Secure the reamer firmly on a matched arbor before mounting in the machine spindle, and confirm all set screws and drive lugs are properly engaged. Always power down and lock out the machine before changing tooling. Use cutting fluid appropriate for the workpiece material to extend tool life and achieve the specified surface finish.
