Value Collection SM1500028 Chucking Reamer 7/16 in Cobalt

Product Description

The VALUE COLLECTION SM1500028 is a cobalt steel chucking reamer designed to finish-ream drilled or bored holes to precise tolerances. The 7/16 inch (0.4375 inch) cutting diameter removes material from pre-drilled holes and brings the bore to a consistent, repeatable size. Cobalt steel construction handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel. The bright, uncoated finish suits general-purpose reaming across a range of ferrous and non-ferrous materials. Six spiral flutes in a right-hand cutting direction provide smooth chip evacuation and reduce chatter during the cut.

This chucking reamer is sized for machine use in drill presses, lathes, machining centers, and CNC setups where a straight-cylindrical shank seats securely in a drill chuck or collet. The 1-3/4 inch flute length handles typical through-hole and shallow blind-hole applications in production and job-shop environments. Machinists, tool-and-die workers, and maintenance technicians reach for this reamer when hole tolerances are tighter than a drill alone can achieve.

Key Features

• Cobalt steel construction resists heat and wear on harder workpiece materials
• Six spiral flutes with right-hand cutting direction for smooth chip flow and reduced chatter
• 0.4375 inch (7/16 inch) cutting diameter for precise hole finishing
• 7 inch overall length provides reach and rigidity in standard machine setups
• Straight-cylindrical shank seats in drill chucks and collets without modification
• Bright, uncoated finish suitable for use with common cutting fluids

Compatibility

Designed as a machine chucking reamer for use in drill presses, lathes, and machining centers that accept a straight-cylindrical shank tool in a standard drill chuck or collet holder.

Installation Notes

Install in a drill chuck or collet that matches the straight-cylindrical shank diameter and ensure the tool is fully seated and securely clamped before use. Always pre-drill or bore the hole close to final size before reaming — the reamer is a finishing tool, not a material-removal tool. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Follow shop safety procedures and machine manufacturer guidelines for spindle speed and feed rate selection.
