Value Collection 144429601100000 Letter K Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429601100000 is a Letter K chucking reamer ground from high-speed steel (HSS) for precision hole finishing in metal workpieces. With a reamer diameter of 0.281 inches and a straight-cylindrical shank, it mounts directly in a drill chuck or collet for reliable concentricity. The bright, uncoated finish suits general-purpose ferrous and non-ferrous material applications where added coating is not required. Right-hand cutting geometry and straight flutes provide clean, consistent stock removal when bringing a drilled hole to final size. Overall length is 6 inches with a 1.5-inch flute length, keeping the tool rigid in standard machine setups.

This chucking reamer is suited for machine shop, toolroom, and maintenance applications where Letter K diameter holes are required to close tolerances. Typical uses include finishing drilled bores on manual lathes, knee mills, and drill presses. The straight-cylindrical shank accepts standard three-jaw chucks and ER-style collet systems without modification. It is sized for light-to-moderate material removal to bring an undersize hole to finished diameter, and is appropriate for use in both production and repair environments.

Key Features

• Letter K diameter (0.281 inches) for precise hole finishing to standard letter-series tolerances
• HSS construction provides good wear resistance across ferrous and non-ferrous workpiece materials
• Straight flutes deliver consistent cutting action and are easy to inspect and resharpen
• Bright uncoated finish suited for general-purpose use without coating-related dimensional offset
• Right-hand cutting direction compatible with standard CW machine spindle rotation
• Straight-cylindrical shank fits three-jaw chucks and collet holders without adapters

Compatibility

Designed as a general-purpose chucking reamer for use in any machine spindle or chuck setup accepting a straight-cylindrical shank tool in the Letter K diameter range.

Installation Notes

A licensed machinist or qualified toolroom technician should install and operate this reamer in a properly aligned machine spindle. Power down and lock out the machine before mounting or changing the tool. Secure the shank fully within the chuck or collet to the recommended engagement depth for the holder in use. Run at manufacturer-recommended cutting speeds for HSS tooling and apply appropriate cutting fluid for the workpiece material to extend tool life and protect hole finish.
