Hertel 72038615 Chucking Reamer 0.8610 in Hss 8 Flute

Product Description

The HERTEL 72038615 is a chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing and smooth surface finishes in drilled or bored holes. It features 8 straight flutes with right-hand cutting action, a straight-cylindrical shank for standard chuck mounting, and measures 10 inches in overall length with a 2-5/8 inch flute length. The 0.8610 inch diameter falls within the 0.7000 to 0.9999 inch decimal range. Machinists and toolroom professionals use this reamer in drill presses, lathes, and machining centers where tight hole tolerances are required.

This chucking reamer is suited for production and toolroom environments where repeatable hole sizing is critical. The straight-cylindrical shank allows direct chucking in standard drill chucks or collet systems. Right-hand cutting direction is compatible with conventional clockwise spindle rotation. The 8-flute configuration improves chip clearance and surface finish compared to lower-flute-count reamers, making it appropriate for through-holes and blind-hole finishing in ferrous and non-ferrous materials.

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, and CNC machining centers equipped with a chuck or collet system capable of holding a straight-cylindrical shank.

Installation Notes

This reamer is installed by a machinist or toolroom technician. Secure the straight-cylindrical shank firmly in a suitable drill chuck or collet before operation. Always bring the spindle to a full stop before changing tooling. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
