Explore our export-ready industrial tool program engineered to rigid European specifications. In addition to our flagship metric thread dies, we manufacture fully ground cutting, drilling, and finishing systems tested in demanding automotive and structural operations.
In high-torque powertrain systems, hydraulic assemblies, and structural fastening throughout Maribor and the Drava industrial corridor, external metric threads require flawless lead entry, precise flank angles, and predictable chip evacuation. Our manufacturing facility produces circular dies (DIN EN 22568) and hexagon die nuts (DIN 382) engineered to withstand extreme torsional stress across austenitic stainless steel, high-tensile carbon steels, and ductile alloys.
We manufacture metric dies from vacuum-hardened HSS M2 (6542), cobalt-alloyed M35 (Co 5%), and powder-metallurgy HSSE-PM steels. With uniform carbide distribution and hardness levels reaching 64–67 HRC, our dies resist abrasive flank wear and micro-chipping even during continuous automated lathe threading of 304 and 316 grade stainless steel.
Standard dies feature a 1.75 to 2.25 pitch chamfer lead for smooth torque transition. For blind threaded studs or close-to-shoulder operations, we grind short 1.25-pitch leads. For automated CNC lathe threading, our spiral point (gun nose) metric dies drive swarf forward ahead of the cut, completely eliminating thread binding and face gouging.
Ground to strict ISO 6g tolerance classes (with optional 6e for pre-galvanized bolts and 4h for aerospace-grade precision fits), all dies undergo specialized surface engineering. Options include steam tempering (black oxide) for anti-welding coolant retention, TiN physical vapor deposition for high lubricity, and TiAlN for heat-intensive dry threading.

Maribor holds a rich engineering legacy as Slovenia’s industrial hub, pivoting rapidly toward smart automation, commercial e-mobility systems, and precision sub-tier manufacturing. Our export operations supply metric thread cutting tools directly matched to local factory shop floors.
Situated in the historic TAM industrial zone, modern automotive suppliers manufacture suspension links, steering arms, and brake caliper housings. Our M6–M16 6g round dies provide chatter-free external threading on hardened alloy steel studs, ensuring tight vibration tolerances demanded by German and Austrian OEMs.
Serving regional bus builders and rail maintenance hubs connected to Maribor’s primary rail network, our heavy-duty M18 to M36 hexagon die nuts allow rapid on-chassis thread chasing and repair without disassembling bulky structural bogies or air reservoir brackets.
Maribor-based machine builders and automation integrators rely on our fine-pitch metric dies (such as M12x1.25 and M14x1.5) for pneumatic manifolds, ball screw mounts, and sensor adapter spindles requiring concentricity within 0.015 mm TIR.
Hydroelectric power stations along the Drava River require corrosion-resistant stainless steel fasteners. Our cobalt M35 steam-tempered dies cut clean metric threads on 316Ti rods and valve shaft stems, preventing surface galling in damp subterranean generator halls.
As Slovenia strengthens its supply chain integration with Austrian (Styria) and German industrial sectors, tooling procurement managers in Maribor face shifting production requirements. Here is how our precision metric die program supports these evolving standards.
Vehicle lightweighting trends require threading high-strength structural alloys like 42CrMo4 and aluminum-silicon castings. Conventional carbon steel dies fail prematurely under these loads. We supply vacuum-hardened HSS-E cobalt dies designed with acute relief angles that reduce cutting torque by up to 28% and prevent tear-out.
European environmental directives are driving Slovenian machine shops toward Minimum Quantity Lubrication (MQL) and dry threading. Our advanced TiAlN and AlCrN multi-layer coatings form an ultra-hard aluminum oxide thermal barrier, permitting surface speeds up to 15 m/min without thermal softening or welded edge buildup.
Serving Maribor's manufacturers with agile factory-direct deliveries, our export supply chain utilizes sea-freight corridors into the Port of Koper for bulk container shipments, combined with direct air express hubs into Graz Airport (GRZ) and Ljubljana (LJU) for rapid 48-hour delivery of custom CNC die runs.
Founded in March 2007 in Danyang—the heart of China's premium cutting tool cluster—Jiangsu WRD Tools Co., Ltd. operates as a dedicated OEM/ODM manufacturer with RMB 10 million in registered capital. We are an authentic production facility, not a trading intermediary. Every single metric threading die, twist drill, and hole saw is manufactured in-house under uncompromising DIN and ISO metrology protocols.
With annual revenues exceeding RMB 80 million, our plant was awarded High-Tech Enterprise status by the Jiangsu Provincial Government in 2019. Our external thread cutting tools and precision ground drills are relied upon by premier multinational cutting tool brands across Western Europe and the Americas.
Everything procurement heads, tooling engineers, and distributors in the Podravska region need to know regarding technical standards, import processing, and custom manufacturing.
Solid round dies (DIN EN 22568) maintain an exact fixed diameter and produce rigid, consistent ISO 6g threads across continuous production runs on CNC lathes. Split dies feature an adjustable expansion slot, allowing manual operators to slightly adjust pitch diameter for loose or interference fitting in maintenance workshops.
ISO 6g is the universal European standard for untreated bolts and threaded shafts. If your Maribor facility applies heavy electrolytic zinc or hot-dip galvanizing, choose our undersized ISO 6e or 6az dies to prevent assembly bind after surface plating.
Yes. Our CNC toolroom grinds left-hand (LH) metric dies (e.g., M12x1.25 LH for circular saw spindles and bicycle hubs) and special pitch combinations (such as M18x1.0 or M27x1.5) with standard lead times under 15 working days.
Shipments to Slovenia follow EU customs procedures (TARIC code for threading dies: 8207.40). Bulk orders ship via container into the Port of Koper within 28–32 days. Urgent tool orders ship via DHL or FedEx straight into Maribor or Graz within 4 to 6 business days.
When cutting external threads on AISI 304 or 316 stainless bar stock, water-soluble emulsions must have at least 8–10% oil concentration with extreme-pressure (EP) chlorinated or ester additives. For manual tapping or low-speed threading, sulfurized neat cutting oil prevents thread tearing.
Standard off-the-shelf single metric dies have an MOQ starting at 50 to 100 pieces per size. Custom-branded tap and die sets in custom metal or molded plastic boxes with bilingual Slovenian/English labeling typically begin at 500 sets.
Whether you require standard DIN EN 22568 round dies for automotive Tier-2 manufacturing in Tezno or custom TiAlN-coated external threading tools for tough alloys, our engineering specialists will provide comprehensive technical drawings and competitive FOB/CIF quotation within 24 hours.
