GRABER

What GRABER does

GRABER (GRA.BER. s.r.l.) is an Italian family-owned precision tooling manufacturer founded in 1968 and headquartered in Gravellona Toce (province of Verbano-Cusio-Ossola), Italy. The company designs, produces, and sells drilling tools and accessories for the ferrous metallurgy industry, with a product portfolio organized into eight core lines: drill bits (Borer, Ejector, Join, Galileo, Leonardo, Appia), drill bars (round, light/hexagonal), soaker bars, shank couplings (threaded, keyed, quick-coupling, QuickRelease), hammer shafts, milling cutters and core drills, ball check valves, and injection/blowing lances. These components form an interconnected system for blast furnace taphole and refractory drilling operations, supporting standardized coupling interfaces (R32, R35, R38, GB27, DIN405, keyed, and quick-release systems).

The firm's technical core is a proprietary manufacturing process that produces tubes from solid billets (full bars), enabling drill bars and related components with specifications that the company claims are difficult for competitors to replicate. This capability, developed over 40+ years since the firm's 1982 specialization in deep drilling, underpins just-in-time delivery on demanding custom orders and supports tailored dimensions, threads, and profiles on customer request. All production — from design through hot forming, deep drilling, machining, assembly, and shipping — is conducted at two production units in Gravellona Toce, using EU-sourced raw materials and an in-house 48.1 kW photovoltaic system. Quality is managed under ISO 9001 (2008, upgraded to 2015).

Commercially, GRABER operates a B2B enterprise field-sales model, targeting the world's leading ferrous metallurgy groups globally via direct sales through its website, LinkedIn presence, downloadable technical brochures, and published case studies (e.g., Appia, QuickRelease). Pricing is custom quotation-based and not publicly disclosed, with multi-year supply arrangements implied by long-tenured customer relationships (20+ years cited). The company has no disclosed external investors, parent, subsidiaries, or public listing; it remains independently held by the founding Grandi family, with Ferruccio Grandi serving as chairman.

Broad incumbents

• Sandvik: Swedish multinational with a Mining and Rock Solutions division that produces rotary drilling tools, drill bits, and consumables for mining and rock excavation. Comparable to GRABER because both serve hard-rock/abrasive drilling applications, though Sandvik is far larger and serves mining customers rather than steel mills specifically.
• Epiroc: Swedish mining and infrastructure equipment manufacturer offering rotary and percussive drill bits, rods, and consumables. Comparable to GRABER as a producer of drilling consumables for hard-rock applications, though Epiroc operates at massive scale and primarily serves mining customers.
• Kennametal: US-based tooling manufacturer producing metal cutting tools, wear-resistant components, and mining/construction consumables including drill bits. Comparable to GRABER in tungsten carbide drill bit production for demanding applications, though Kennametal serves a much broader cross-section of industries.
• ISCAR (IMC Group): Israeli metal cutting tools manufacturer producing milling cutters, drills, and turning tools. Comparable to GRABER's milling cutter line (especially the interchangeable inserts product), though ISCAR serves general machining rather than blast furnace applications.

Direct peers

• Boart Longyear: Global drilling tools and services provider serving mining, energy, and infrastructure. Comparable because it produces drill rods, bits, and drilling consumables for hard-rock and abrasive conditions similar to blast furnace taphole drilling, though its primary market is exploration drilling rather than blast furnace steel production.
• Tricon Drilling Tools: Manufacturer of drilling consumables including drill bits and rods for mining and quarrying. Comparable to GRABER as a niche drill bit and drilling consumables producer serving hard-rock applications, though Tricon's focus is more on exploration and production drilling than blast furnace steel operations.

Emerging players

• Walter Tools (Walter AG): German precision tooling manufacturer specializing in metal cutting tools, inserts, and milling systems. Comparable to GRABER's milling cutter product line and carbide insert expertise, though Walter primarily serves general machining customers rather than ferrous metallurgy specifically.
• Dormer Pramet: Manufacturer of drilling, milling, and turning tools including rotary drill bits and threading tools. Comparable to GRABER in drill bit manufacturing and carbide tooling, though Dormer Pramet is a general industrial supplier rather than a steel-mill specialist.
