Value Collection 144429604070000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604070000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.4070-inch diameter. Chucking reamers are machine-driven tools used in drill presses, lathes, and CNC machining centers to bring holes to tight dimensional tolerances and improve surface finish. This reamer features a straight-cylindrical shank for secure chuck holding, 8 straight flutes for consistent chip evacuation, and a bright uncoated finish. Right-hand cutting direction is standard for conventional machine operation. At 0.16 pounds, it is a lightweight, single-piece tool suited for production and maintenance machining environments.

This chucking reamer is appropriate for general metalworking applications where hole diameter accuracy in the 0.4000 to 0.4999-inch range is required. Typical applications include finishing holes in ferrous and non-ferrous materials in job shops, maintenance facilities, and light manufacturing operations. The straight flute geometry is well suited to through-holes and shorter blind holes where chip clearance is manageable. It is installed and operated by machinists, toolmakers, and maintenance mechanics using standard machine toolholding equipment.

Key Features

• 0.4070-inch reamer diameter for precise hole finishing
• HSS construction provides durability across a range of common workpiece materials
• 8 straight flutes for smooth cutting action and consistent chip removal
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction for conventional machine spindle operation
• Bright uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with a chuck or collet capable of accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists or maintenance mechanics. Always power down and lock out the machine spindle before mounting or removing the tool from the chuck or collet. Secure the shank fully within the toolholder to prevent slippage under cutting load. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
