What Samputensili does

Samputensili, now operating as Star SU Europe S.r.l., is an Italian manufacturer of precision gear cutting tools headquartered in Bentivoglio (Bologna). Founded in 1937 and integrated into the Star organization, the company designs and produces hobs, power skiving tools, master gears, chamfering and chamfer-roller tools, deburring tools, shaper cutters, and shaving cutters, with a proprietary Scudding® line that machines internal and external gears/splines without requiring an undercut or groove. Production is delivered in collaboration with strategic manufacturing partners, and the company maintains an INNO Tools sub-brand for advanced tooling solutions.

The business serves industrial customers across Aerospace, Automotive, Gear Tools, Industrial Application, Jobshops, Marine Applications, Pumps & Compressors, and Wind Power. Its go-to-market is an enterprise field-sales model led by a Sales Director, supported by recurring presence at major trade shows (EMO Hannover, IMTS Chicago, AMB Stuttgart, CIMT, GrindTec, IMTEX) and technical seminars in growth markets such as India. Distribution extends globally through a joint venture, Star SU International Trading (Shanghai), with Star Cutter Company for the Chinese market. Revenue is generated via quote-based, one-time sales of engineered tooling and related maintenance services, with pricing not publicly disclosed.

Ownership sits under Star as the strategic parent; Samputensili Cutting Tools was previously acquired and rebranded as Star SU Europe. The 2015 acquisition of SICMAT expanded manufacturing capability, and the company has since pursued geographic expansion (China JV, India demand generation) alongside product line development (Scudding®, INNO Tools). Customer education is delivered through Samputensili Master training programs, reinforcing lock-in with precision manufacturing customers who face high switching costs in qualified production environments.

Expansion highlights6 records

Broad incumbents

• Sandvik Coromant: Sandvik's metal cutting division offers cutting tools and tooling solutions overlapping with Samputensili's gear cutting range. Much larger conglomerate serving broader metalworking applications but competes for gear tooling budgets at tier-1 customers.
• Walter Tools (Walter AG): Walter AG, part of the Sandvik group alongside Sandvik Coromant, provides precision cutting tools including gear-related tooling. Comparable as a European precision tooling competitor serving similar automotive and industrial gear manufacturing customers.
• Mitsubishi Materials Corporation: Mitsubishi Materials produces cutting tools including gear-related tooling and inserts. Comparable as a major Asian-headquartered tooling supplier with global reach competing for similar industrial and automotive gear manufacturing contracts.
• Kennametal: Kennametal manufactures metal cutting tools and wear-resistant solutions used in gear production and machining. A broad incumbent serving aerospace, automotive, and industrial markets with comparable tooling applications but a wider product portfolio.
• Liebherr (Gear Cutting Machines and Tools): Liebherr manufactures gear cutting machines and corresponding tools serving automotive, aerospace, and heavy machinery markets. Comparable in gear technology offerings but as part of a much broader industrial conglomerate portfolio.

Emerging players

• OSG Corporation: OSG is a Japanese cutting tool manufacturer with global operations producing taps, end mills, and gear cutting tools. Comparable as an Asian-headquartered precision tooling player competing in automotive and industrial gear applications.
• EMUGE-FRANKEN: EMUGE-FRANKEN is a German precision cutting tool manufacturer with strong gear cutting tool capabilities serving European industrial customers. Comparable in product range and target market focus, though with broader clamping and threading offerings.

Direct peers

• Star Cutter Company: Star Cutter is both a strategic partner (JV in China) and a US-based manufacturer of custom cutting tools including gear cutting tools. Directly comparable in gear tooling products, target markets, and corporate relationship via the Star SUC organization.
• Gleason Corporation: Gleason is the global leader in gear manufacturing machinery and tooling, directly competing with Samputensili across hobs, shaper cutters, and shaving tools. Highly comparable in product portfolio, target customers (automotive/aerospace gear manufacturers), and gear technology expertise.

Others

• SAMAG (Samp S.p.A.): SAMAG (formerly part of SAMP Group) produces gear cutting machines complementary to Samputensili's tools. Closely related historical entity (shared Italian industrial heritage) serving the same gear manufacturing customers with equipment rather than consumable tooling.
