Value Collection 144429603110000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603110000 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.3110-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, making it a direct fit for CNC machining centers, manual mills, and drill presses. With 6 flutes and a right-hand cutting direction, it produces consistent, clean-walled bores suitable for precision fit applications including dowel pin holes and bearing seats.

This chucking reamer is suited for machine-shop and maintenance applications where a finished hole in the 0.3000 to 0.3499 inch diameter range is required. It is appropriate for use in both production environments and job-shop settings. Machinists, tool-and-die makers, and maintenance technicians working on jigs, fixtures, and mechanical assemblies will find this reamer a practical choice for achieving tight tolerances in through-holes and blind holes.

Key Features

• 0.3110-inch finished-hole diameter for precise bore sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• 6 straight flutes provide consistent chip evacuation and a smooth bore finish
• Right-hand cutting direction for conventional machine operation
• Bright, uncoated finish — ready to use without additional surface prep

Compatibility

Designed as a standard chucking reamer for use in drill presses, manual mills, and CNC machining centers equipped with drill chucks or collet systems accepting a straight-cylindrical shank. Suitable for hole diameters in the 0.3000 to 0.3499 inch decimal range.

Installation Notes

This reamer is installed and operated by machinists and toolroom technicians. Always secure the workpiece firmly before reaming and ensure the shank is fully seated and tightened in the chuck or collet. Reaming should be performed at appropriate spindle speeds with cutting fluid applied to extend tool life and improve surface finish. Never ream a hole that has not been pre-drilled or bored to leave only a small amount of stock for the reamer to remove.
