Value Collection 144429602750000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602750000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to precise tolerances. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance across a wide range of ferrous and non-ferrous materials. The 0.2750-inch diameter and straight-cylindrical shank make it compatible with standard drill chucks and collet systems. With 6 flutes and a right-hand cutting direction, this reamer removes material evenly and produces a smooth, accurate bore finish. It is a standard, non-dowel-pin, non-over-under-size tool suited to general-purpose precision work.

This chucking reamer is used in machine shop, maintenance, and production environments where hole finishing to close tolerances is required. Typical applications include reaming through-holes and blind holes in metal workpieces mounted on drill presses, lathes, milling machines, or CNC machining centers. The straight-cylindrical shank seats directly in a drill chuck or collet without additional adapters. It is appropriate for machinists, tool-and-die makers, and maintenance technicians working in light to medium production settings.

Key Features

• 0.2750-inch reamer diameter within the 0.2500 to 0.2999-inch decimal-inch range
• High-speed steel (HSS) construction for durability across common workpiece materials
• 6 straight flutes for smooth, even material removal and accurate bore sizing
• Right-hand cutting direction compatible with standard machine rotation
• Straight-cylindrical shank seats directly in drill chucks and collet holders
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks and collet systems on drill presses, lathes, milling machines, and CNC machining centers that accommodate a straight-cylindrical shank tool.

Installation Notes

This reamer should be installed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and power is locked out before mounting or removing the tool from the chuck or collet. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Avoid forcing the reamer into an undersized pilot hole — pre-drill or bore to the recommended undersize before reaming to finished diameter.
