Value Collection 144429600716000 Chucking Reamer 7/16 in Hss

Product Description

The VALUE COLLECTION 144429600716000 is a straight-flute chucking reamer designed to finish-ream holes to a precise 7/16 inch (0.4375 inch) diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing and smooth surface finish in a wide range of common shop materials. The straight-cylindrical shank seats securely in a drill chuck or collet, and the right-hand cutting direction suits standard spindle rotation. Overall length is 7 inches with a 1-3/4 inch flute length. It is well suited to maintenance machinists, tool-and-die shops, and general metalworking operations.

This reamer is used in drilling and boring operations where a drilled hole must be brought to a precise final diameter with improved roundness and surface finish. Typical applications include reaming holes in metal fixtures, machine components, and fabricated assemblies. The 7-inch overall length gives adequate reach for most bench-top and knee-mill setups without excessive deflection. A single reamer is supplied per package, making it a practical single-replacement purchase for production or maintenance use.

Key Features

• Reamer diameter: 7/16 inch (0.4375 inch decimal equivalent)
• High-speed steel (HSS) construction for hardness and wear resistance in metalworking applications
• Straight flute geometry for clean, chatter-resistant cuts in through-holes and blind holes
• Bright, uncoated finish — no coating buildup to affect tolerance
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank for direct chuck or collet mounting without adapters

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, knee mills, and CNC machining centers equipped with a drill chuck or straight-shank collet sized for a 7/16 inch shank.

Installation Notes

Chucking reamers are installed and removed by a licensed machinist or qualified shop technician. Power down and lock out the machine spindle before changing tooling. Secure the straight-cylindrical shank fully in the chuck or collet to minimize runout before engaging the workpiece. Feed rate and cutting speed should follow standard HSS reaming guidelines for the material being machined; excessive feed pressure can cause chatter or bell-mouthing at the hole entrance.
