Hertel 45676335 Chucking Reamer 0.351 in Solid Carbide

Product Description

The HERTEL 45676335 is a solid carbide chucking reamer designed for precision hole finishing in machining operations. With a reamer diameter of 0.351 inches and a bright, uncoated finish, it delivers consistent bore sizing in a wide range of materials. The straight flute geometry and right-hand cutting direction make it well suited for through-hole and shallow blind-hole applications where chip evacuation is straightforward. Machinists and tool and die professionals rely on this type of reamer to bring pre-drilled holes to final tolerance with minimal stock removal. Overall length is 3.5 inches with a 1.25-inch flute length.

This chucking reamer is intended for use in CNC machining centers, manual knee mills, and drill presses where a standard straight cylindrical shank can be held in a drill chuck, collet, or keyless chuck. It is suited for production and toolroom environments working with ferrous and non-ferrous metals, plastics, and composites where tight bore tolerances are required. With six flutes, it produces a smooth finish on the reamed bore wall. It is sold individually and is a current catalog item from HERTEL.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 0.351-inch reamer diameter for precision hole finishing to close tolerances
• Six straight flutes for smooth bore finish and efficient chip evacuation
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight cylindrical shank fits standard drill chucks and collets
• Bright, uncoated finish suitable for general-purpose reaming applications

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in machining applications requiring a 0.351-inch finished bore diameter with a standard straight cylindrical shank interface.

Installation Notes

Installation and use should be performed by qualified machinists or tool and die professionals. Ensure the machine spindle and workpiece are fully stopped and locked out before changing or inspecting the reamer. Secure the straight shank firmly in the chuck or collet to the manufacturer-specified clamping depth to prevent pullout under cutting loads. Carbide tooling is brittle and should not be subjected to impact or dropped on hard surfaces, as chipping or fracture may result.
