Value Collection 144429603810000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603810000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3810-inch diameter. Chucking reamers are machine-held tools used in drill presses, lathes, and CNC machining centers to bring a hole to tight dimensional tolerance and a smooth surface finish. This reamer features a straight-cylindrical shank for secure chuck retention, six straight flutes for clean chip evacuation, and a bright/uncoated finish suited to general-purpose ferrous and non-ferrous stock. Right-hand cutting direction is standard for conventional machine operation.

This reamer is appropriate for job shops, tool rooms, maintenance departments, and production machining environments where a hole in the 0.3500 to 0.3999-inch diameter range requires final sizing. It is particularly well suited to moderate-volume applications on manual machines and CNC setups alike. The straight flute geometry performs reliably in through-holes and short blind-hole applications where chip clearance is adequate.

Key Features

• 0.3810-inch finished-hole diameter in the 0.3500 to 0.3999-inch reamer range
• High-speed steel (HSS) construction for toughness and re-sharpenability
• Six straight flutes for efficient chip clearance and consistent finish
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Right-hand cutting direction compatible with conventional machine spindle rotation
• Bright/uncoated finish for general-purpose use across a broad range of workpiece materials

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank tool in the applicable diameter range.

Installation Notes

Chucking reamers are installed and removed by a qualified machinist with the machine spindle fully stopped and locked out per applicable safety procedures. Secure the straight-cylindrical shank firmly in a drill chuck or collet to minimize runout, which directly affects hole quality and reamer life. Always apply cutting fluid appropriate to the workpiece material to reduce heat and extend tool life. Do not run a reamer in reverse, as reverse rotation will damage the cutting edges.
