An integrated production system in Korea — we own every step from raw powder to the finished, ground and inspected part. That control is what keeps tolerance, grade consistency and lead time together.
In-House System
From powder formulation to final inspection, production stays under one roof. We develop our own grades, hold standard stock for fast delivery, and machine to drawing for everything custom.
The Process
Tungsten and cobalt powders are weighed and milled to the target grade — grain size and binder content tuned to the wear and toughness profile of the application.
Powder is compacted in dies or extruded to near-net shape, with coolant-hole geometry and allowance built in for final grinding.
Compacts are sintered at high temperature into dense, fully consolidated cemented carbide — the step that defines hardness and structural integrity.
5-axis CNC grinding brings geometry to drawing — flutes, edges, diameters and lengths held to ±2 µm.
Edge prep, lapping and optional PVD/CVD coatings such as TiAlN or DLC extend tool life for the target material.
Every lot is verified on Zoller and CMM equipment, documented for traceability, and packed for stable worldwide shipment.
Equipment & Metrology
Geometry and grade are verified, not guessed. Our metrology room ties every shipment back to its process record.

Grades & Materials
Representative cemented-carbide grade families. We tune cobalt content and grain size to your hardness, toughness and wear targets.
Low cobalt, sub-micron grain — for sharp edges and high wear resistance in cutters and inserts.
Balanced hardness and toughness for end mills, drills and turning tools.
Higher toughness for dies, punches and impact-loaded wear parts.
High cobalt, coarse grain for shock resistance in heavy-duty service.
