Value Collection 144429603790000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603790000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3790-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank allows secure seating in standard drill chucks and collet holders. Six evenly spaced straight flutes provide a smooth cutting action with a right-hand cutting direction. This reamer is suited for machine-tool applications where tight hole tolerances are required and a hand-reamer is not appropriate.

Chucking reamers of this diameter range are commonly used in machine shop and production environments, including job shops, maintenance facilities, and manufacturing lines. The 0.3790-inch diameter falls within the 0.3500 to 0.3999 decimal-inch range, making this tool appropriate for medium-bore finishing operations on lathes, drill presses, and milling machines. Machinists, toolmakers, and maintenance technicians working with precision bore requirements will find this a standard fit for everyday reaming tasks.

Key Features

• 0.3790-inch finished bore diameter for tight dimensional tolerance
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Bright, uncoated finish — no additional coating to affect final bore size
• 6-flute straight configuration for smooth chip evacuation and consistent surface finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet systems

Compatibility

Designed as an OEM-style machine reamer compatible with standard drill chucks and collet holders accepting a straight-cylindrical shank in the 0.3500 to 0.3999 decimal-inch diameter range.

Installation Notes

Chucking reamers should be installed by a qualified machinist or toolmaker in a properly aligned machine spindle. Before mounting, ensure the machine is fully de-energized and the chuck or collet is clean and free of debris. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never use a chucking reamer by hand or force it into an undersized pilot hole — always pre-drill or bore to the recommended undersize before reaming.
