About YG-1

Turning Inserts
YG-1 offers a range of carbide turning inserts for general CNC turning operations. The YG-Turn insert family includes CNMG, WNMG, DNMG, CCMT, and TCMT shapes in grades covering steel, stainless steel, and cast iron machining. The YG-3000 grade is a versatile CVD-coated insert for general steel turning, while YG-5000 provides PVD-coated sharp edges for stainless steel and aluminum. YG-1 turning inserts are designed to be compatible with all standard ISO toolholders, providing an economical alternative to premium brands for routine production turning.
Milling Cutters
YG-1’s milling range centers on solid carbide end mills, which represent the company’s strongest product category. The X-POWER series features premium 4-flute solid carbide end mills with AlTiN coating and variable helix geometry for chatter-free milling in steel up to 50 HRC. The Alu-Power series is specifically designed for high-speed aluminum milling with polished flutes and ZrN coating for anti-adhesion properties. The Power Long Shank end mills provide extended reach for deep pocket milling with reinforced shanks for rigidity. The 4-POWER roughing end mill features serrated cutting edges for aggressive material removal in steel roughing. YG-1 also offers the Eco-Mill series providing economical 2-flute and 4-flute end mills for general-purpose milling.
Drilling Tools
YG-1’s drilling portfolio includes the YG-Drill solid carbide drill series with TiAlN coating and through-coolant channels for high-speed drilling in steel and stainless steel. The YG-Spot Drill and YG-Center Drill ranges provide precision pre-drilling tools. YG-1 also produces the Multi-Drill series offering step drills and combination drill-countersink tools for efficient hole preparation. The Deep Hole Drill series provides extended-length carbide drills for deep-hole applications up to 15xD.
Grooving & Threading
This is YG-1’s founding specialty and remains a core strength. The YG-Tap range is one of the world’s most comprehensive tap portfolios, including: Spiral Point Taps (for through-hole tapping with forward chip evacuation), Spiral Flute Taps (for blind-hole tapping with backward chip evacuation), Forming/Roll Taps (thread forming without cutting, ideal for ductile materials), and Pipe Taps (NPT, NPTF, BSP thread forms). The YG-VXL series features premium cobalt HSS taps with TiAlN coating for high-speed machine tapping. The YG-Threading Insert range provides partial and full-profile threading inserts for CNC turning centers in metric and imperial forms.
