Value Collection 144429600600000 Chucking Reamer Letter F Hss

Product Description

The VALUE COLLECTION 144429600600000 is a straight-flute chucking reamer designed for finishing drilled holes to a precise diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer holds a Letter F diameter of 0.2570 inches, placing it in the 0.2500 to 0.2999 inch decimal range. The straight-cylindrical shank seats securely in a drill chuck or collet holder, and the right-hand cutting direction is standard for conventional machine operation. With a 6 inch overall length and a 1.5 inch flute length, this tool is suited for production and maintenance machining environments where repeatable hole sizing is required.

This chucking reamer is used in manual or CNC lathes, drill presses, and machining centers for reaming through-holes or blind holes to close tolerances. It is appropriate for ferrous and non-ferrous workpiece materials in general machine shop, toolroom, and maintenance repair operations. The bright finish indicates no additional surface treatment, making it suitable for applications where coating interaction with the workpiece material is a concern. A machinist or toolroom technician typically selects this reamer as a finishing step after drilling or boring to achieve final hole geometry.

Key Features

• Letter F diameter — 0.2570 inches decimal equivalent for precise hole finishing
• High-speed steel (HSS) construction for durability in general machining applications
• Straight flute geometry suited for through-hole and short blind-hole reaming
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cut, right-hand flute — compatible with standard spindle rotation
• Bright, uncoated finish — no coating interaction with workpiece material

Compatibility

Designed as a standard chucking reamer for use in drill chucks and collet systems accepting a straight-cylindrical shank; compatible with drill presses, lathes, and machining centers set up for right-hand rotation finishing operations.

Installation Notes

A machinist should power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. The reamer should be run at reduced speeds compared to drilling, with appropriate cutting fluid applied to extend tool life and improve surface finish. Do not use this tool to remove excessive stock — pre-drill or bore the hole to near-final size before reaming. Inspect the cutting edges for chips or wear before each use to avoid damage to the workpiece bore.
