Hertel 45674488 Chucking Reamer 0.0655 in Solid Carbide

Product Description

The HERTEL 45674488 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a cutting diameter of 0.0655 inches and an overall length of 1.75 inches, this compact reamer is built for tight-tolerance bore sizing in small-diameter work. The 4-flute straight geometry produces a clean, controlled cut in right-hand rotation, while the bright polished finish reduces friction and promotes chip evacuation. A straight shank allows direct mounting in standard collet chucks, drill chucks, or reaming fixtures. Machinists and tool-and-die professionals select this reamer where dimensional accuracy and surface finish in small bores are critical.

This reamer is suited for production and job-shop environments where small-diameter hole finishing is required in ferrous and non-ferrous materials. The solid carbide construction provides the rigidity needed to hold close tolerances at higher spindle speeds compared to high-speed steel alternatives. Typical applications include finish-reaming drilled or bored holes to precise diameter in CNC machining centers, knee mills, and bench drill presses. It is commonly used in instrument manufacturing, mold work, and precision component production where hole quality cannot be left to drilling alone.

Key Features

• 0.0655 inch cutting diameter for small-bore precision finishing
• Solid carbide construction for rigidity and wear resistance
• 4-flute straight flute geometry for controlled material removal and smooth finish
• Bright polished coating reduces friction and aids chip clearance
• Straight shank compatible with standard collet and drill chuck setups
• Right-hand cutting direction for conventional spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank reamer holders, collet chucks, and drill chucks on CNC and manual machining equipment accepting tools in the 0.0500 to 0.0999 inch diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool from the chuck. Secure the straight shank firmly in a properly sized collet or chuck to prevent runout that could damage the cutting edges or compromise bore diameter. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
