Engineered to meet rigorous DIN, ISO, and NAS standards. Optimized for medical device manufacturing, aerospace maintenance, and precision CNC metalworking across Costa Rican Free Trade Zones.
Costa Rica has emerged as Latin America's primary high-tech manufacturing and life-sciences hub. Our OEM/ODM twist drill manufacturing lines are tailored specifically to solve the thermal and mechanical machining friction encountered in Central America's flagship industrial parks.
Costa Rica is home to over 30 tier-1 medical technology multinationals operating within the Coyol Free Zone, Zona Franca ZETA, and Global Park. Manufacturing surgical instruments, orthopedic implants (Ti-6Al-4V ELI), and 316L stainless steel cardiovascular components requires zero-burr micro-drilling.
Our Custom 2mm-10mm Solid Tungsten Carbide Drill Bits and micro-diameter internal coolant drills utilize ultra-fine micrograin carbide substrates (0.4μm) with AlTiN PVD coatings. This geometry prevents work hardening, reduces exit burs to under 5 microns, and maintains strict dimensional stability across 10,000-cycle medical manufacturing production runs without coolant contamination.
With major aircraft Maintenance, Repair, and Overhaul (MRO) facilities expanding around Juan Santamaría International Airport (SJO), technicians handle complex stacked materials including 2024-T3 / 7075-T6 aluminum alloys, titanium spar caps, and carbon-fiber reinforced polymers (CFRP).
Our supply line incorporates German HSS M35 5% Cobalt Parallel Coated Twist Drills and NAS 965 Type D threaded shank adapter drills. Designed with a 135° self-centering split point, these tools eliminate bit walking on hand-held pneumatic drills, cut cleanly through stacked aluminum-titanium joints without delamination, and comply with strict FAA and EASA structural repair documentation.
Generating over 98% of its electricity from renewable sources (hydroelectric, geothermal, and wind), Costa Rica’s heavy industrial sectors require aggressive metal removal solutions for high-nickel turbine alloys, cast steel penstocks, and geothermal valve housings exposed to corrosive hydrogen sulfide environments.
We provide heavy-duty DIN 6535/6537 Solid Carbide Coolant-Through Drills capable of deep hole depths up to 50xD. Featuring parabolic flute geometry and high-pressure internal coolant channels (up to 70 bar), these drills effectively clear chips from deep blind holes, dramatically reducing spindle downtime during hydroelectric turbine refurbishment.
Costa Rica’s massive agricultural export economy (pineapple, banana, coffee processing) relies heavily on stainless steel processing, washing, and automated packaging lines fabricated from AISI 304 and 316 stainless steels.
Machining austenitic stainless steels causes extreme work hardening and thermal friction. Our M35 Cobalt and TiAlN Coated Twist Drills feature optimized helix angles and reinforced web thicknesses that resist edge chipping, extended tool life by 300% over standard HSS drills, and maintain pristine hole surfaces required for food-grade hygienic welding.
As supply chains shift toward nearshoring in the Americas, Costa Rican manufacturing plants are rapidly upgrading from conventional machine tools to high-speed 5-axis CNC machining centers. This technological leap imposes stringent requirements on cutting tool performance.
With high-speed machining (HSM) becoming standard in Costa Rica's Free Trade Zones, tool life is dictated by thermal barrier performance. Modern sub-micron carbide grain sizes (0.4–0.6μm) coupled with nano-structured TiAlN and AlTiN coatings allow spindle speeds exceeding 15,000 RPM while maintaining tool integrity under intense friction.
Deep hole drilling in difficult-to-cut metals (such as Inconel 718 or Titanium Grade 5) can trigger tool failure within seconds if chips packing occurs. Twin internal coolant holes deliver pressurized cutting fluid directly to the cutting lip, instantly flushing chips, cooling the cutting point, and improving surface roughness to Ra < 0.4μm.
Aligned with Costa Rica's national decarbonization strategy, ISO 14001 certified factories are reducing coolant waste through Minimum Quantity Lubrication (MQL). Our OEM/ODM specialized twist drills feature micro-polished flutes that reduce friction co-efficients, enabling clean dry or MQL drilling in aluminum and structural steel.

Technical solutions and procurement details for manufacturing managers, CNC programmers, and tooling distributors in Costa Rica.
For austenitic stainless steels like 316L and 316LVM used in medical devices, we recommend solid carbide twist drills with a 135° or 140° point angle, featuring split-point web thinning and an AlTiN PVD coating. The high titanium content in AlTiN provides a thermal barrier up to 900°C, while the split point reduces axial thrust forces, eliminating burr height upon drill exit.
Tropical micro-climates can accelerate coolant degradation and rust formation on tool shanks. Our OEM twist drills feature passivation treatments on un-coated HSS tools and full PVD encapsulation on carbide drills. Furthermore, our drill shanks conform strictly to h6 tolerances, preventing coolant bypass and micro-corrosion inside precision hydraulic chucks or shrink-fit holders.
Yes. We regularly export tooling directly to companies operating under Costa Rica's Free Trade Zone Regime (Regimen de Zona Franca). We supply complete export documentation, customs invoices, commercial packing lists, and Certificates of Conformance (CoC) to facilitate tax-free import clearing through San José or Limón customs checkpoints.
For standard catalog sizes, we maintain instant dispatch stock with zero minimum order quantity. For custom OEM/ODM tooling—such as specialized step drills, custom diameters, or proprietary PVD coatings—our MOQ typically starts at 10 to 50 pieces depending on geometry complexity. We also offer rapid sampling programs for initial CNC test runs.
When drilling holes deeper than 3xD, external flood coolant cannot effectively reach the cutting lip because escaping chips block the flute orifice. Internal coolant channels force pressurized fluid directly to the cutting zone, fracturing chips into manageable segments and cooling the cutting edge instantly. This increases tool life by up to 400% and enables continuous drilling without peck cycles.
Absolutely. We partner with industrial distributors throughout Costa Rica and Central America to supply white-label cutting tools. We offer custom laser marking on drill shanks (brand logo, part number, batch code) and provide branded plastic packaging sleeves or multi-sets tailored to your corporate identity.
