Value Collection 144429601500000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429601500000 is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Built from high speed steel (HSS) with a bright polished finish, this reamer holds tight dimensional tolerances and delivers a clean surface finish in a wide range of ferrous and non-ferrous materials. The straight shank seats directly into a drill chuck or collet, making it fast to deploy on a drill press, lathe, or milling machine. At 0.316 inches in diameter and 6 inches overall length, it handles typical through-hole and blind-hole finishing operations where an O-letter or 0.316-inch final bore diameter is required. Cutting direction is right hand.

This reamer is suited for machine shop, maintenance, and tool-room applications where a finish-reamed hole is needed to close tolerance. Common use cases include fitting dowel pins, press-fit bushings, and precision shaft bores in both production and repair contexts. The 1.5-inch flute length accommodates standard material thicknesses encountered in benchtop and floor-model machine tools. It is sold individually and is appropriate for machinists, millwrights, and tool-and-die technicians working in job shop or industrial maintenance environments.

Key Features

• High speed steel construction provides good hardness and wear resistance across a broad range of workpiece materials
• Bright polished finish reduces built-up edge and promotes chip evacuation in the flutes
• Straight shank accepts standard drill chucks and collets without an adapter
• Right-hand cutting direction compatible with conventional machine tool spindle rotation
• 1.5-inch flute length handles typical stock thicknesses for finish-reaming operations
• Letter O diameter (0.316 inches) covers the 0.3000 to 0.3499-inch reamer diameter range

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with a drill chuck or collet that accepts a straight shank. Suitable for any application requiring a finish-reamed hole at the O-letter or 0.316-inch diameter.

Installation Notes

Chucking reamers are installed and operated by machinists or millwrights using standard machine tool practices. Secure the straight shank firmly in a drill chuck or collet before operation and confirm the spindle rotates in the right-hand direction. Always ream at reduced spindle speed compared to drilling, and use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never reverse spindle rotation while the reamer is engaged in the workpiece, as this will damage the cutting edges.
