SG66 Grade
The carbide grade SG66 is available for all common Horn insert systems. The in-house coating also enables a short delivery time for special tools. SG66 cannot replace the CBN grade. Horn has, however, filled the gap for particularly difficult groove turning applications. In comparison, the CBN grade achieves twice the cutting speed and more when…
SG3P Carbide Grade
The SG3P carbide grade also enables shorter cycle times for thread production thanks to higher cutting values, including when processing materials that are difficult to machine. In addition, the combination of an ultra-fine grain carbide powder and the high temperature resistant coating results in high process reliability and better component…
Solid Carbide Milling Cutter
Due to their geometry and good chip breaking, the milling tools are suitable for machining numerous other materials. Due to the precise combination of the substrate, the macro and micro geometry as well as the IG3 coating, the milling system exhibits high performance and long tool life. The coating in particular offers high temperature resistance…
Supermini
The insert of the Supermini Type 105 system requires only one tool holder for well over 1,000 insert variants. This applies equally to left-hand and right-hand versions. The carbide inserts are available in coated and uncoated versions in different grades for every application including hard machining up to 66 HRC. The patented droplet shape of…
Carbide Grade IG3
IG3 when compared to previous generation offerings sets the new benchmark for tool life and machine time efficiency. IG3 offers similar performance to our previous standard, TH3, while in some instances increasing tool life beyond twice that of TH3. Making it a fantastic drop-in replacement in established processes.
Adjustable Damped Boring Bar
The exact adjustment of the damper, made of a carbide rod supported in O-rings, is made from the outside via an adjustment screw. Adjustment is achieved by fine-tuning the pre-tension of the O-rings. This allows the boring bar to be precisely set according to the vibration occurring in each application. As standard, Horn offers the tools from…
Polished Rake Faces
Especially for milling aluminium alloys and plastics, Horn offers the indexable inserts with polished rake faces on all four edges from stock to counteract the formation of built-up edges. In conjunction with the positive chip breaker geometry, the sharp ground cutting edge produces a soft cut and high surface quality. The special grade is…
DR Reaming System
As with other tool systems, high-performance reaming systems are also subject to demanding requirements. In addition to high process reliability, long tool life and low tool costs, modern reaming tools must fulfil further criteria. These include, among other things, the modularity of the tools. While machining with an HSS reamer is partially…
M911, M913 and M928 Nine-Edged Milling Systems
The nine-edged milling systems M911, M913 and M928 are stocked in cutting widths from 1.5 mm (0.059") to 3 mm (0.118") as standard. The maximum milling depth is 3.5 mm (0.138") (M911), 4.5 mm (0.177") (M913) and 6.5 mm (0.256") (M928). The inserts are available with different coatings to suit the material to be machined.…
Modular Tooling System
The modular system has a selection of tool holders for turrets and other tool carrier interfaces based on common machine types. The matching grooving tool holders with integral coolant supply allow height adjustment of the cassettes and their mounting in the normal or overhead position, on the left or right of the holder.
S224 Type Indexable Insert
Horn has revised the clamping of the S224 type indexable insert for use in Swiss-type lathes. In order not to have to remove the holder for indexing or changing the insert, the Horn engineers relocated the clamping screw to the side. Clamping now takes place via a camshaft. This allows the insert to be clamped quickly at either side of the holder…
FB Geometry
The geometry is available as a standard tool for the 224, 229, S34T, 315, and 64T systems for precision machining of external grooves. For internal machining, it is available for the 105, 108, 111, 114, and 216 systems. Further insert types are available as special tools and can be delivered quickly via the Greenline system, whereby it is possible…
DDHM CVD Diamond-Tipped Tool System
The DDHM system is aimed primarily at customers in the tool and die-making industries. The focus is on machining carbide punches and dies efficiently. The tool system also offers significant advantages in other areas such as the medical and aerospace sectors, the automotive industry, and punching, forging and forming technology. The diamond tools…
EH Geometry
The stable cutting edge enables feed rates in the range of f = 0.25-0.4 mm/rev, during grooving and parting-off, which results in reduced machining time across multiple operations. Reliable chip evacuation and control is ensured by a special chip formation. High feed rates require a stable machine  when grooving and parting-off, as well as secure…

Combating the crisis with bits and bytes: Digitalization in the machine tool industry and metalworking

May 5, 2020 — In the midst of the corona crisis, in between restrictions on movement and contact, a key word that seems to be a universal remedy for industry and the economy is suddenly doing the rounds again: digitalisation. The virologists who are constantly searching for answers surrounding the corona epidemic should be able to use the large…
