Hertel 45676798 Chucking Reamer 0.438 in Solid Carbide

Product Description

The HERTEL 45676798 is a solid carbide chucking reamer designed to finish-size drilled or bored holes to tight tolerances. At 0.438 inches in diameter with a 4 inch overall length and a 1-3/8 inch flute length, this reamer delivers precise, repeatable results in ferrous and non-ferrous materials. The 6-flute, straight-flute geometry with a right-hand cutting direction produces smooth bore finishes while maintaining dimensional accuracy. A bright polished finish reduces friction and improves chip evacuation. Solid carbide construction provides rigidity and wear resistance well beyond high-speed steel alternatives, making it a dependable choice for production and job-shop environments alike.

This chucking reamer is suited for use on CNC machining centers, manual mills, and drill presses wherever a straight-shank tool can be held in a drill chuck, collet, or end-mill holder. It is appropriate for through-hole and blind-hole finishing operations in metals including steel, cast iron, aluminum, and brass. The 0.438 inch diameter falls within the 0.4000 to 0.4999 inch reamer diameter range and is well-matched to precision fixture, jig, and assembly work requiring close-tolerance bore sizing.

Key Features

• Solid carbide construction for superior rigidity and extended tool life compared to HSS reamers
• 6-flute straight geometry delivers a smooth, consistent surface finish in the bored hole
• Right-hand cutting direction compatible with standard spindle rotation
• Bright polished finish reduces built-up edge and aids chip flow
• Straight shank accepts standard drill chucks, collets, and hydraulic holders
• 0.438 inch diameter for precision hole sizing in production or toolroom applications

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in any machine tool spindle that accepts a straight-shank tool within the appropriate collet or chuck size range.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians. Secure the straight shank firmly in a clean, concentric holder to minimize runout before use. Power down and lock out the machine spindle before changing tooling. Always use appropriate cutting fluid for the workpiece material, and never reverse spindle rotation while the reamer is engaged in the bore.
