Value Collection SM0407430 Chucking Reamer 0.7430in Hss

Product Description

The VALUE COLLECTION SM0407430 is a chucking reamer designed for precision hole finishing in metal and similar materials. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth bore surfaces. The reamer measures 0.7430 inches in diameter with an overall length of 9.5 inches. Six straight flutes and a right-hand cutting direction provide consistent chip evacuation and clean finishes in through and blind holes. The straight-cylindrical shank seats securely in drill chucks, collet chucks, and floating holders used on lathes, drill presses, and milling machines.

This chucking reamer is suited for machine reaming operations in job shops, tool rooms, and production environments. It is appropriate for finishing bored or drilled holes to close tolerance in ferrous and non-ferrous workpieces. The 0.7430-inch diameter falls within the 0.7000 to 0.9999 inch range category, making it a practical selection for shaft fits, bushing seats, and precision locating holes. Machinists and tool-and-die workers are the primary users. It is sold individually and requires no additional components for standard installation in compatible toolholding equipment.

Installation Notes

A licensed machinist or skilled operator should install this reamer in a properly sized chuck or collet holder, ensuring the shank is fully seated and the holding device is tightened to the equipment manufacturer's specification. The spindle and any automatic feeds should be powered down before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the cutting edges for wear or damage before each use and remove the reamer from service if chipping or deflection is observed.
