Value Collection 144429603780000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603780000 is a chucking reamer designed to bring bored or drilled holes to a precise final diameter with a smooth, accurate finish. Manufactured from high-speed steel (HSS) with a bright, uncoated surface, this reamer measures 0.3780 inches in diameter and features a straight-cylindrical shank for secure chuck mounting. Six straight flutes and a right-hand cutting direction produce clean, consistent material removal in a wide range of ferrous and non-ferrous workpiece materials. Machinists and tool-and-die professionals install this type of reamer in drill presses, lathes, or machining centers when hole tolerance and surface finish are critical.

This chucking reamer is suited for finishing operations in machine shops, maintenance facilities, and production environments where close-tolerance holes are required. The straight-cylindrical shank seats directly in standard drill chucks or collets, making it straightforward to integrate into existing setups. Its 0.3780-inch diameter falls within the 0.3500 to 0.3999 inch reamer diameter range, making it a practical choice for finish-reaming holes to that specific dimension in both prototype and production runs.

Key Features

• 0.3780-inch cutting diameter for precise hole finishing to close tolerances
• High-speed steel (HSS) construction provides durability across a broad range of materials
• Six straight flutes promote smooth cutting action and accurate sizing
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank seats in drill chucks or collets without special toolholders
• Bright, uncoated finish — no coating buildup to affect critical diameter dimensions

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with drill chucks or collets that accept a straight-cylindrical shank.

Installation Notes

Chucking reamers should be installed by qualified machinists following established shop safety practices. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the chuck. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Never use a reamer to remove excessive stock — pre-drill or bore the hole close to final size before reaming.
