Hertel 45676434 Chucking Reamer 0.363 in Solid Carbide

Product Description

The HERTEL 45676434 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. Built with a straight flute geometry and a straight shank, this reamer delivers accurate, repeatable sizing in a broad range of drilling and boring operations. The 0.363-inch cutting diameter and 6-flute configuration produce smooth bore finishes with minimal runout. At 3.5 inches overall length with a 1.25-inch flute length, it fits standard chuck toolholders on CNC machining centers, drill presses, and manual lathes. The bright, uncoated solid carbide construction provides rigidity and wear resistance suitable for ferrous and non-ferrous workpiece materials. Machinists, toolroom operators, and production floor personnel install and operate this tool.

This chucking reamer is used in machining environments where a drilled or bored hole must be brought to a precise final diameter. Typical applications include through-hole and blind-hole reaming on machining centers and lathes in job shops, production facilities, and maintenance tool rooms. The straight flute design suits softer materials and short-chipping workpieces where chip evacuation is straightforward. The straight shank allows direct chuck mounting without an adapter. This reamer is not configured as a dowel pin reamer and is not an over- or under-size specialty tool.

Key Features

• Solid carbide construction for rigidity and extended tool life compared to HSS equivalents
• 0.363-inch cutting diameter with 6 flutes for smooth, accurate bore finishing
• Straight flute geometry suited to softer materials and short-chip alloys
• Straight shank for direct mounting in standard drill chucks or collet holders
• Bright, uncoated finish — no coating concerns for materials sensitive to coated tools
• Right-hand cutting direction for standard spindle rotation setups

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard straight-shank chuck toolholders on CNC machining centers, manual lathes, and drill presses requiring a 0.363-inch finished bore diameter.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with cutting tool setup and machine tool operation. Power down the spindle and confirm the machine is in a safe, locked-out state before mounting or removing the reamer from the toolholder. Ensure the straight shank is fully seated and the chuck or collet is properly torqued to the toolholder specification before initiating a cut. Do not use this reamer as a primary drilling tool — always pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
