Value Collection 144429604164000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604164000 is a straight-flute chucking reamer designed to bring bored or drilled holes to precise final diameter in machine shop and production environments. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer measures 0.6406 inches (41/64 inches) in diameter and delivers a right-hand cutting action suitable for use in drill presses, lathes, and CNC machining centers. With a 9 inch overall length and a 2.25 inch flute length, it is sized for moderate-depth through-holes and blind holes in ferrous and non-ferrous materials. Machinists and tool-and-die technicians are the primary users.

This chucking reamer is applied in precision finishing operations where hole tolerance and surface finish are critical. The straight-cylindrical shank allows it to seat directly in a drill chuck or collet without special adapters. It is well suited for production runs requiring consistent hole sizing across multiple workpieces in steel, aluminum, brass, and similar machinable materials. The reamer falls within the 0.5000 to 0.6999 inch diameter range, making it a standard size for common fastener clearance and bearing seat applications.

Key Features

• 41/64 inch (0.6406 inch) diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across a wide range of materials
• Straight flute geometry suited for through-holes and short blind holes
• Right-hand cutting direction compatible with standard machine rotation
• Straight-cylindrical shank seats in standard drill chucks and collets without adapters
• Bright, uncoated finish — no coating to add dimensional uncertainty to the cutting edge

Compatibility

Designed as a standard-style chucking reamer for use in drill presses, lathes, and machining centers that accept a straight-cylindrical shank tool in the 41/64 inch diameter range.

Installation Notes

Chucking reamers are installed and removed by a qualified machinist with the machine fully powered down and the spindle at a complete stop. Secure the straight-cylindrical shank firmly in the chuck or collet before operation, and verify runout with a dial indicator when tight tolerances are required. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use a chucking reamer to remove excessive stock — pre-drill or bore the hole to within 0.005 to 0.015 inches of finish size before reaming.
