Complete Guide to Horn Cutting Tools: History, Product Lines & Grade Selection
About Horn
Paul Horn GmbH is a German precision cutting tool manufacturer founded in 1969 by Paul Horn in Tübingen, Germany—the same city that is home to Walter AG. Horn has built an exceptional reputation as a specialist in grooving, parting-off, and precision turning tools for high-precision CNC machining applications. The company remains family-owned and is known for its meticulous German engineering, producing tools that achieve tolerances and surface finishes that exceed industry standards. Horn operates manufacturing facilities in Tübingen, Germany, and in the United States (through Horn USA), with distribution in over 50 countries. The brand is particularly revered in the medical device, automotive precision parts, and watch-making industries where micron-level accuracy is critical. With 3,193 products on Hooguu, Horn offers a focused but premium selection of grooving, parting, and precision turning solutions.
Horn Product Lines
Turning Inserts
Horn’s turning portfolio focuses on precision turning rather than heavy roughing. The Horn DAH (Double-Angle Holder) system provides precision turning capability for Swiss-type lathes and multi-spindle automatics. The Supermini system offers the world’s smallest indexable boring bars, capable of boring holes as small as 0.5 mm diameter. Horn’s turning inserts feature exceptionally sharp cutting edges with edge radii below 5 microns, enabling mirror-finish turning of aluminum, brass, and engineering plastics. The Mini System and S272 platforms provide modular turning solutions for small-part machining on Swiss-type and sliding-headstock lathes.
Milling Cutters
Horn offers a specialized milling range focused on precision micro-milling and profile milling. The Horn 3V6 solid carbide end mill series provides precision profile milling with diameters from 0.1 to 6 mm for micro-machining applications. The Horn DAH Milling system offers precision face milling for small-part production on Swiss-type lathes. The DS-System provides precision slot milling cutters for narrow slot machining with widths from 0.2 to 3 mm. Horn’s milling tools are particularly valued in the medical and watch industries for machining titanium, stainless steel, and precious metal components.
Drilling Tools
Horn’s drilling range includes the Bore-Check system for in-process bore measurement and precision boring. The Horn Micro Drill series offers solid carbide micro-drills from 0.1 mm diameter for medical device and electronics manufacturing. The Eco Drill system provides economical indexable drilling for standard precision applications. Horn’s drilling tools are designed for high-precision, small-diameter holes where accuracy and surface finish are paramount.
Grooving & Threading
This is Horn’s undisputed specialty and where the brand truly excels. The Horn Supermini Type 105 is the industry’s smallest grooving system, capable of grooving in holes as small as 0.5 mm diameter. The Horn Mini System Type 315 provides external grooving, internal grooving, and parting-off in small-diameter applications. The Horn DAH 83 system handles precision grooving on Swiss-type lathes with tool widths from 0.5 to 4 mm. The Horn S274 and S275 series offer multi-directional grooving capability for complex groove profiles. For parting-off, the Horn DAH 84 system provides the narrowest parting widths (from 1.0 mm) for material-saving production on bar-fed lathes. Horn’s threading range includes micro-threading tools for threads as small as M0.5, essential for medical implants and precision instruments.
