Value Collection 144429601950000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429601950000 is a high-speed steel (HSS) chucking reamer designed to bring bored or drilled holes to a precise finished diameter. With a 0.1950-inch cutting diameter and a straight-cylindrical shank, it seats securely in a drill chuck or collet for accurate, repeatable sizing. The six-flute straight configuration shears cleanly through steel, cast iron, aluminum, and similar workpiece materials. The bright, uncoated finish keeps the tool at close dimensional tolerance right out of the box. Machinists, tool-and-die workers, and maintenance professionals use chucking reamers like this one when a drilled hole needs to meet tight tolerance for a press fit, clearance fit, or dowel pin location.

This reamer is suited for manual drill press work and CNC or manual lathe and mill operations where a through-hole or blind-hole finish diameter of 0.1950 inches is required. The straight-cylindrical shank accepts standard drill chucks and ER-style collet systems without an adapter. It is not configured as a dowel pin reamer and is not an over- or under-size variant, making it the standard go-to choice when the nominal diameter is the target. Right-hand cutting direction matches conventional spindle rotation on all standard machine tools.

Key Features

• 0.1950-inch finished hole diameter, within the 0.1500 to 0.1999-inch decimal inch range
• Six straight flutes for smooth material removal and consistent surface finish
• HSS construction provides good wear resistance across a wide range of workpiece materials
• Bright, uncoated finish maintains close dimensional accuracy
• Straight-cylindrical shank seats in standard drill chucks and collet holders
• Right-hand cutting direction for use with conventional spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank at the 0.1950-inch diameter range.

Installation Notes

Chucking reamers are installed by qualified machinists or maintenance technicians; secure the shank firmly in a chuck or collet before operation and verify runout before cutting. Always ream a pre-drilled or bored hole that is undersized by the appropriate stock allowance for the material being machined — do not attempt to ream from solid. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect the reamer for chipping or wear before each use and replace if cutting edges are damaged.
