Value Collection 14442960078000S Chucking Reamer 7/8 in Hss

Product Description

The VALUE COLLECTION 14442960078000S is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to precise diameter tolerances. It measures 0.875 inches (7/8 inch) in diameter with an overall length of 10 inches and a spiral flute length of 2-5/8 inches. The straight-cylindrical shank seats securely in a drill press chuck, CNC lathe, or milling machine collet. Right-hand spiral flutes pull chips away from the cutting edge, helping maintain hole finish quality. Machinists, toolroom technicians, and maintenance mechanics use this reamer when a drilled hole must be opened to a close-tolerance final diameter.

This reamer is suited for use in machine shops, maintenance facilities, and production environments where 7/8-inch finish-reamed holes are required in ferrous and non-ferrous materials. It fits standard drill press, lathe, or mill setups that accept a straight shank. Typical applications include bearing seat preparation, bushing fits, and precision bore finishing where a drilled hole alone does not achieve the required surface finish or dimensional accuracy.

Key Features

• HSS construction provides hardness and wear resistance suitable for a wide range of workpiece materials
• Spiral right-hand flutes evacuate chips efficiently during the reaming pass
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• 0.875-inch diameter delivers a precise finish bore in the 0.700 to 0.9999-inch range class
• 2-5/8-inch flute length accommodates moderate material depth in a single pass
• Right-hand cutting direction matches conventional machine rotation

Compatibility

Designed as a standard straight-shank chucking reamer for use in any drill press, lathe tailstock, or milling machine setup that accepts a straight-cylindrical shank tool with a 7/8-inch cutting diameter.

Installation Notes

A licensed machinist or experienced toolroom operator should set up and run this reamer. Before mounting, confirm the spindle and workpiece are secured and the machine is at a safe reaming speed with cutting fluid applied to extend tool life and protect hole finish. Never reverse spindle direction while the reamer is engaged in the bore, as back-cutting damages flutes and degrades hole finish. Follow applicable shop safety procedures and machine manufacturer guidelines for tooling installation and secure chuck tightening.
