Hertel 45674744 Chucking Reamer 0.1235 in Solid Carbide

Product Description

The HERTEL 45674744 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a nominal diameter of 0.1235 inches and an overall length of 2.25 inches, this reamer is sized for small-bore work where dimensional accuracy is critical. The four-flute, right-hand cutting geometry with a straight flute configuration delivers consistent stock removal and a clean, accurate finish. A bright polished coating reduces friction and aids chip evacuation. Machinists and toolroom professionals use chucking reamers like this one to bring drilled or bored holes to a precise final diameter.

This reamer is suited for use in CNC machining centers, manual mills, and drill presses where a straight shank and collet or chuck mounting is standard. The 0.625-inch flute length makes it appropriate for shallow-to-moderate depth holes in ferrous and non-ferrous materials. Applications include precision component manufacturing, fixture and jig work, and production runs requiring tight hole tolerances. The solid carbide construction provides rigidity and wear resistance that HSS tooling cannot match at this diameter range.

Key Features

• 0.1235-inch finished bore diameter for precision hole sizing
• Solid carbide construction for maximum rigidity and tool life at small diameters
• Four-flute straight geometry for consistent, chatter-free cutting action
• Right-hand cutting direction compatible with standard spindle rotation
• Bright polished finish reduces friction and aids chip clearance
• Straight shank fits standard collets, chucks, and reamer holders

Compatibility

Designed as a standard straight-shank chucking reamer for use in CNC or manual machine tools equipped with collet chucks or drill chucks accepting straight-shank tooling in the applicable diameter range.

Installation Notes

Chucking reamers are installed and removed by qualified machinists with the machine powered off and the spindle fully stopped. Ensure the shank is fully seated and securely clamped in the collet or chuck before operation. Use the appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain bore quality. Do not use a chucking reamer as a substitute for a drill to remove bulk material.
