Value Collection SM0403155 Chucking Reamer 0.3155 in Hss

Product Description

The VALUE COLLECTION SM0403155 is a chucking reamer designed to finish-size drilled or bored holes to a precise 0.3155-inch diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent material removal and smooth bore surfaces in metalworking applications. The straight-cylindrical shank allows secure seating in standard drill chucks, collets, and machine spindles. Four straight flutes provide controlled chip evacuation and stable cutting geometry. Right-hand cutting direction suits conventional lathe, drill press, and CNC machine spindle rotation. This tool is intended for machinists, toolmakers, and maintenance professionals working in production or job-shop environments.

This chucking reamer is suited for finishing holes in ferrous and non-ferrous metals where tight diameter tolerances are required. Typical applications include sizing holes for close-tolerance pin fits, bushings, and bearing bores in both light manufacturing and maintenance-repair operations. The 0.3155-inch diameter falls within the 0.3000 to 0.3499 inch decimal-inch reamer diameter range, making it a standard selection for precision hole finishing at this size class.

Key Features

• 0.3155-inch finished bore diameter for precision hole sizing
• High-speed steel (HSS) construction resists heat and wear during cutting
• Bright, uncoated finish suitable for general-purpose metalworking
• 4 straight flutes for stable cutting and efficient chip clearance
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard chucks and collets without adapters

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with standard straight-shank chuck or collet toolholding systems.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or toolmaker familiar with precision hole finishing operations. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation, and verify spindle runout is within acceptable limits to avoid oversizing the bore. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Discontinue use if chatter, excessive heat, or diameter drift is observed, as these conditions indicate incorrect speed, feed, or tool condition.
