Hertel 79888996 Chucking Reamer 0.065 in Solid Carbide

Product Description

The HERTEL 79888996 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a reamer diameter of 0.065 inches and a tight tolerance range of 0.0000 to 0.0002 inches over nominal, this tool delivers accurate, repeatable bore sizing in small-diameter holes. The 4-flute straight flute geometry provides smooth cutting action and consistent chip evacuation. The bright, uncoated solid carbide construction offers rigidity and wear resistance well-suited to ferrous and non-ferrous materials. Machinists and toolroom professionals use this reamer in CNC machining centers, drill presses, and manual lathes where precise hole sizing is required.

This chucking reamer is suited for small-hole finishing operations in production and toolroom environments. The straight cylindrical shank allows it to be held securely in standard drill chucks, collets, and floating reamer holders. With an overall length of 1.5 inches and a flute length of 0.375 inches, it is well-proportioned for shallow reaming passes in blind or through holes at the 0.065-inch diameter range. Right-hand cutting direction is standard for conventional spindle rotation.

Installation Notes

Chucking reamers should be installed by a qualified machinist following the machine tool manufacturer guidelines. Power down and lock out the spindle before changing tooling. Ensure the shank is fully seated and clamped securely in the holder before operating. Use appropriate cutting fluid for the workpiece material to maintain tool life and hole finish quality.
