Horn is presenting no fewer than 20 new or recently introduced cutting tool products on its 232m² stand (6-210) at MACH 2026 (NEC Birmingham, 20-24 April). A key focus is the company’s carbide inserts featuring chip-breaking geometry pressed directly into the green blank before sintering, delivering high-speed, repeatable and cost-efficient production.

This approach removes the need for post-sintering laser cutting or grinding, traditionally required for miniature inserts due to the difficulty of maintaining precision during heating. With these challenges now overcome, new Supermini type 105 GM (geometry moulded) inserts are priced comparably to standard versions without chip breakers.

As with machined geometries, the sintered designs eliminate long, stringy swarf that can damage tools or workpieces. Suitable for boring and internal threading in holes down to 4 mm diameter, the inserts use teardrop-shaped blanks to maximise contact area in the holder, improving rigidity, preventing twist and maintaining accurate centre height. This design enhances stability, particularly in long overhang applications.

Available in TH35 and IG35 grades, the inserts are compatible with a wide range of holders and support internal coolant delivery. The Supermini system comprises around 2500 standard variants.

Further highlights include new GM inserts for metric ISO internal threading, first shown at EMO 2025, delivering reliable chip control in hole diameters from 5 mm. The Mini 114 system for deep axial grooving (up to 10 mm) and Mini 111 and 108 inserts with sintered I-geometry also feature, enabling effective chip breaking in finishing applications. Also on show is the six-edged 66T grooving system, offering increased depth capability and competitive cost per edge, alongside the S234 system for parting off to depths of 33 mm with high process reliability.
