Applications for YG-1
YG-1’s solid carbide drills are ideal for production environments focused on reducing machining costs and ensuring consistent production schedules.
Typical use cases include minimizing tool changes on mass production lines or reducing setup time between batches.
Combining high-hardness, heat-resistant Z-Coating with a wave-shaped cutting edge design, YG-1 drills extend tool life and lengthen intervals between regrinds.
This leads to lower cost per hole and more predictable production planning.
Note: Performance may vary depending on tool type and machining conditions such as spindle speed, feed rate, coolant, and machine rigidity.

Overview
This is YG-1’s flagship series for high-efficiency drilling in mass production lines—especially for steel and cast iron.
The proprietary Z-Coating protects the cutting edge from heat and wear during continuous operation and when machining hard materials.
Its wave-shaped cutting edge and helical thinning geometry reduce cutting forces and break chips into smaller pieces,enabling smooth evacuation—even at depths of 3×D to 5×D.
This series is best suited for optimized processes where tool life consistency and productivity gains are critical.
Compatible Materials
- Carbon and alloy steels (including quenched/tempered)
- Stainless steels (austenitic and martensitic)
- Cast iron (gray and ductile)
- Non-ferrous metals (aluminum, copper, brass)
- Heat-resistant alloys and titanium alloys
- Hardened steels (up to approx. 45 HRC)
Lineup
- DGN506 Series – 3×D (Short Type) with Coolant Holes
- DGN508 Series – 5×D (Long Type) with Coolant Holes

https://product.yg1.solutions/product/series?type=undefined&type2=undefined&idx=23
Overview
A versatile series designed for general-purpose drilling across a broad range of materials such as carbon steel and pre-hardened steels (HRc30–50).
The drills feature a TiAlN-based coating with special surface treatment to improve chip evacuation and maintain consistent hole quality.
Unlike the FORCE-driven PRO series for highly controlled processes, GENERAL is made for flexible use across diverse conditions.
It supports materials like steel, cast iron, non-ferrous metals, and even some plastics, with depth options of 3×D, 5×D, and 8×D.
Ideal for job shops, small-lot production, or initial process setups requiring reliable all-around performance.
Compatible Materials
- General & cast steels (unalloyed, low-alloy, high-alloy)
- Stainless steels (austenitic and martensitic)
- Cast iron (gray and ductile)
- Non-ferrous metals (aluminum, copper, brass)
- Heat-resistant alloys (nickel- and titanium-based)
- Hardened materials (medium hardness)
Lineup
- DH406 Series – 3×D (Short Type) with Coolant Holes
- DH408 Series – 5×D (Long Type) with Coolant Holes
- DH421 Series – 8×D (Extra Long Type) with Coolant Holes
- DH414 Series – 3×D (Stub Type) with Coolant Holes
- DH416 / DH711 Series – 3×D (Short Type) with Coolant Holes
- DH418 / DH712 Series – 5×D (Long Type) with Coolant Holes
- DH423 Series – 3×D (Short Type) without Coolant Holes
- DH424 Series – 5×D (Long Type) without Coolant Holes
- DH722 Series – 5×D (Long Type) without Coolant Holes
- DH404 Series – 3×D (Short Type) without Coolant Holes

Overview
Made from HSS-PM (high-performance powdered high-speed steel), this series offers excellent toughness and chip control under challenging conditions.
A TiAlN coating enhances wear resistance, while a precision-ground point ensures high positioning accuracy—even on machines with lower rigidity or unstable setups.
A practical choice for pre-drilling or general-purpose use on conventional machines or machining centers where reliability and toughness are priorities.
Compatible Materials
- Aluminum
- Stainless steels
- Carbon steels
- Structural steels
