Value Collection 14442960176400S Chucking Reamer 17/64 in

Product Description

The VALUE COLLECTION 14442960176400S is a straight-flute chucking reamer designed to finish-ream drilled holes to a precise 17/64 inch (0.2656 inch decimal) diameter. Made from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate hole sizing in a wide range of metals and materials. The straight-cylindrical shank seats securely in standard drill chucks and collets. With a 6 inch overall length and a 1-1/2 inch flute length, it is suited for general-purpose reaming on drill presses, lathes, and CNC machining centers. Machinists and tool-and-die professionals reach for this style of reamer when a drilled hole needs to be brought to final tolerance.

This chucking reamer is a general-purpose tool used in machine shops, maintenance facilities, and production environments. It handles finish reaming in ferrous and non-ferrous materials where a drilled hole must meet close dimensional tolerances. The right-hand spiral flute geometry pulls chips forward and away from the cutting edges, reducing chatter and improving surface finish. It is not configured as an over/under size or dowel pin reamer, making it a standard replacement or stock item for everyday reaming operations.

Key Features

• 17/64 inch (0.2656 inch) diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across common workpiece materials
• Right-hand spiral flute direction promotes chip evacuation and reduces chatter
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 6 inch overall length with 1-1/2 inch flute length for versatile machine setups

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a chuck or collet capable of accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by licensed machinists and toolroom technicians. Secure the shank fully in the chuck or collet and confirm runout before cutting. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Pre-drill the hole to within 0.005 to 0.010 inch of final size before reaming; do not attempt to ream an undersized hole in a single pass without a properly sized pilot hole.
