Value Collection 144429603340000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603340000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3340-inch diameter. Built with a straight-cylindrical shank for secure chuck mounting, this reamer features six straight flutes and a right-hand cutting direction for smooth, accurate material removal. The bright, uncoated HSS construction provides adequate hardness and wear resistance for reaming operations in a wide range of ferrous and non-ferrous materials. This tool is suited for machinists and toolroom technicians who require consistent hole tolerance and surface finish in production or maintenance environments.

This chucking reamer is appropriate for use in manual drill presses, lathes, and CNC machining centers where a straight-cylindrical shank is compatible with the collet or drill chuck in use. The 0.3340-inch diameter falls within the 0.3000 to 0.3499 decimal inch reamer diameter range, making it a standard fractional-adjacent size used in close-tolerance hole finishing applications across general machining, toolroom work, and light manufacturing.

Key Features

• 0.3340-inch finished bore diameter for precise hole sizing
• Six straight flutes for consistent chip evacuation and smooth cutting action
• Right-hand cutting direction compatible with standard machine rotation
• HSS tool material provides durability across a broad range of workpiece materials
• Straight-cylindrical shank fits standard drill chucks and collets
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a chuck or collet sized for a straight-cylindrical shank tool. Verify spindle and chuck clearance before installation.

Installation Notes

Chucking reamers are installed and removed by machinists or toolroom technicians — ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight-cylindrical shank firmly in the chuck or collet to prevent slippage during the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use a reamer to remove excessive material; pre-drill or bore the hole to within a few thousandths of the final diameter before reaming.
