Hertel 79891404 Chucking Reamer 15mm Straight Flute Carbide

Product Description

The HERTEL 79891404 is a solid carbide chucking reamer designed to finish-ream bores to a precise 15 mm (0.5906 inch) diameter. Solid carbide construction provides the rigidity and wear resistance needed to hold tight tolerances in ferrous and non-ferrous materials alike. The straight flute geometry delivers clean, accurate hole sizing in through-bore and short blind-bore applications. Overall length is 4 inches with a 1.5-inch flute length, keeping the tool compact for use in CNC machining centers, manual lathes, and knee mills. Machinists and tool-and-die professionals install this reamer using a standard collet or drill chuck with a straight cylindrical shank interface.

This reamer is suited for production and job-shop environments requiring repeatable bore sizing in the 0.5000 to 0.6999 inch diameter range. Typical applications include sizing hydraulic valve bores, bearing seats, bushing housings, and precision-fit pin holes in steel, cast iron, aluminum, and brass workpieces. The compact 4-inch overall length makes it a practical choice for short-reach setups on vertical machining centers and turret lathes.

Key Features

• Solid carbide body for superior rigidity and extended tool life compared to HSS alternatives
• Straight flute design for accurate bore sizing in through-hole and short blind-hole applications
• 15 mm (0.5906 inch) reamer diameter for precision final-pass material removal
• Straight cylindrical shank compatible with collets, drill chucks, and floating reamer holders
• Compact 4-inch OAL with 1.5-inch flute length for short-reach machining setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank collet systems and drill chucks accepting a cylindrical shank in the 0.5000 to 0.6999 inch diameter class.

Installation Notes

Installation is performed by qualified machinists. Secure the straight shank firmly in a collet, drill chuck, or floating reamer holder before use. Ensure the spindle and workpiece fixture are fully locked and the machine is at the correct speed and feed for the workpiece material before engaging the reamer. Never run a reamer in reverse, as this damages cutting edges and degrades bore finish.
