SINTER SUD

What SINTER SUD does

Sinter Sud S.p.A. is an Italian manufacturer of cemented tungsten carbide (metallo duro / widia) products, founded in 1974 and headquartered in Caserta, Italy, with consolidated production since 2003 at a single facility in Sant'Agata de' Goti (Benevento). The company produces solid and coolant-channel carbide rod blanks, rectangular bars, rotary burrs to DIN8033 standard, hexagonal prism inserts, and a broad portfolio of carbide grades (MK12, GF70, K12F, K10F, K06F for metal and wood; SS6, SS10, SS20, K30P, SG2, SG3, K20, K30 for mining, drilling, and stone cutting). Manufacturing relies on Sinter-HIP (Hot Isostatic Pressing) technology from ALD and PVA, DORST pressing equipment, and 2017-2019 Industry 4.0 upgrades.

The company sells primarily to industrial B2B buyers: toolmakers, metal cutting tool manufacturers, woodworking tool manufacturers, and mining and quarrying operators. Go-to-market is sales-led, combining a global network of agents and retailers with exclusive country distributors (Castlebar Corporation for the US since 2019, Mabtools for France) and direct sales capabilities, supplemented by participation in major trade shows including EMO, JIMTOF, IMTS, GRINDTEC, CIMT, and MAKTEK. Pricing is quote-based and not publicly disclosed. The company is certified ISO 9001:2015, ISO 14001:2015, and EMAS, and employs approximately 51 people.

Since 2022, Sinter Sud has operated as a subsidiary of Hyperion Materials & Technologies (Worthington, Ohio, USA), a global hard and super-hard materials platform with roughly 1,600 employees and sales offices in 70+ countries. Founder Antonio Suppa transitioned to an advisory role post-acquisition, with key business leaders retained and reporting into the Hyperion organization.

Core offering

SINTER SUD manufactures premium cemented tungsten carbide (metallo duro/widia) products, including solid and coolant-channel carbide rod blanks, rectangular bars, rotary burrs (DIN8033 standard), and hexagonal prism inserts. The company also develops specialized carbide grades (e.g., MK12, GF70, K10F, K06F, SS10, K30P) tailored for metalworking, woodworking, and mining/drilling/stone cutting applications, serving toolmakers globally with both standard catalog items and custom-engineered parts.

Product overview

SINTER SUD is a manufacturer of cemented tungsten carbide (metallo duro/widia) products established in 1974, specializing in carbide rod blanks (solid and with coolant channels), rectangular bars, and rotary burrs (DIN8033 standard). The company produces specialized carbide grades for three main application areas: metal/metal alloy working (MK12, GF70, K30, K10F, K06F grades), wood working (MK12, GF70, K12F, K10F, K06F grades), and mining/drilling/stone cutting (SS6, SS10, SS20, K30P, SG2, SG3, K20, K30 grades). The product portfolio centers on carbide rods, bars, and rotary burrs, with each product line available in multiple grades optimized for specific material hardness and processing conditions. SINTER SUD is recognized as Italy's leader in carbide cylinder production and operates as part of Hyperion Materials & Technologies following acquisition.
