Wholesaler + Factory

A unique dual-role model built to eliminate middlemen, optimize your cost-per-hole, and accelerate time-to-market.

Manufacturing Excellence

In-house production on Swiss/German CNC grinding centers ensures sub-micron runout tolerance and complete control of every geometry -- from substrate to coating.

  • 100% Virgin Ultra-Fine Tungsten Carbide substrate
  • In-house PVD coating line (AlTiN, TiCN, CrN)
  • Ph.D.-led R&D with ex-KORLOY engineers

Wholesale Advantage

Direct factory pricing, no-MOQ flexibility, and consolidated shipping -- everything a distributor or OEM procurement team needs in one supplier.

  • 60% cost of legacy European brands
  • OEM / White-label & custom geometries
  • Lead times under 7 days for stock items
Product Portfolio

Three Core Product Lines

Engineered for process security, thread accuracy, and extreme-condition reliability across every threading application.

Solid Carbide Taps
01 -- Premium Line

Spiral Fluted Taps

Technical Advantage: This "chip-lifting" action prevents chip accumulation at the bottom of the hole, ensuring a smooth threading process and preventing chipping of the cutting edges. It ensures high thread accuracy even in deep-hole applications.

HSS-PM Powder Metallurgy Taps
02 -- Versatile Line

HSS-PM Taps

Powder metallurgy high-speed steel delivers superior toughness and wear resistance -- the ideal balance between carbide performance and cost-efficiency for general engineering and automotive subcontracting.

Hardness

Cold Forming Taps
03 -- Chipless Line

Spiral Point Taps

Since no chips are produced, the risk of chip-related failures is eliminated. The resulting threads have higher tensile strength and an exceptional surface finish because the grain structure of the metal is compressed rather than severed.
