Value Collection 144429603220000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603220000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3220-inch diameter. The bright, uncoated HSS construction provides reliable cutting performance on a wide range of ferrous and non-ferrous materials. Six straight flutes promote smooth chip evacuation and consistent surface finish in through-holes and blind-hole applications. The straight-cylindrical shank seats securely in standard drill chucks, collet chucks, and floating reamer holders for use in drill presses, lathes, and CNC machining centers. This tool is suited for machinists, tool-and-die makers, and maintenance technicians requiring accurate hole sizing in production and repair work.

This chucking reamer is appropriate for general-purpose hole finishing operations in machine shops, maintenance facilities, and production environments. It is used wherever a drilled hole must be brought to a close-tolerance finish diameter of 0.3220 inches. The right-hand cutting direction and straight-flute geometry make it well-suited for softer steels, aluminum, brass, and similar machinable materials. It is sold as a single unit and is compatible with any spindle or chuck that accepts a straight-cylindrical shank of the corresponding diameter.

Key Features

• 0.3220-inch finished hole diameter, within the 0.3000 to 0.3499-inch decimal inch reamer range
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• 6-flute straight configuration for smooth chip flow and consistent bore finish
• Right-hand cutting direction, compatible with standard clockwise-rotation spindles
• Bright, uncoated finish — no added coating thickness to affect dimensional tolerance
• Straight-cylindrical shank fits standard drill chucks, collet holders, and floating reamer holders

Compatibility

Designed as a general-purpose straight-shank chucking reamer for use in any machine tool spindle or chuck that accepts a straight-cylindrical shank, including drill presses, engine lathes, turret lathes, and CNC machining centers.

Installation Notes

A licensed machinist or qualified maintenance technician should secure the straight-cylindrical shank firmly in a true-running chuck or collet before operation to minimize runout. Always pre-drill or bore the hole to within recommended undersize allowance before reaming — do not use a chucking reamer as a primary hole-making tool. Ensure the workpiece and spindle are properly aligned; misalignment will cause bell-mouthing or chatter. Follow applicable shop safety procedures and use appropriate cutting fluid for the workpiece material.
