YG-1

YG-1 is a South Korean manufacturer of cutting tools, established in 1981 and headquartered in Incheon. The company specializes in end mills, drills, taps, reamers, and other rotary cutting tools for metalworking industries. YG-1’s product line includes high-speed steel (HSS), cobalt, and carbide end mills in square, ball, and roughing configurations, with coatings such as TiN and TiCN available on select models. The brand is known for producing tools that meet ISO 9001 quality management standards, with many items manufactured to metric and inch dimensions for global compatibility. YG-1 tools are used in applications such as die and mold making, aerospace component machining, automotive part production, and general fabrication. The company operates multiple manufacturing facilities in South Korea and has a distribution network that spans over 60 countries. 3G Electric supplies a range of YG-1 end mills, including general-purpose cobalt square end mills (e.g., MPN 04338, 6-flute, 5/8" diameter), cobalt ball end mills with TiCN coating (e.g., MPN 43297CC, 4-flute, 1/4" diameter), HSS square end mills (e.g., MPN 07228, 6-flute, 2" diameter), and double-end HSS square end mills in various sizes and coatings. The cobalt tools are suitable for machining harder materials such as stainless steel and titanium alloys, while HSS variants are appropriate for general-purpose milling of carbon steels and non-ferrous metals. YG-1 end mills are available with flute counts ranging from 2 to 6, lengths of cut from 13/32" to 2", and overall lengths from 2-7/16" to 4-1/2". The tools are designed for use in CNC milling machines, manual mills, and machining centers. 3G Electric supports the YG-1 line by offering these products with logistics support for global shipping, ensuring that plant engineers and procurement specialists can source specific geometries and coatings for their machining operations without relying on local stock limitations.

Common Applications

Die and mold machining — YG-1 cobalt ball end mills (e.g., MPN 43297CC) for contouring and finishing cavities in hardened tool steels.
Aerospace component production — YG-1 cobalt square end mills (e.g., MPN 04338) for milling titanium and nickel-based alloys.
Automotive part manufacturing — YG-1 HSS square end mills (e.g., MPN 07228) for high-volume machining of cast iron and steel components.
General fabrication — YG-1 double-end HSS end mills (e.g., MPN 13040) for slotting and profiling in mild steel and aluminum.
Roughing operations — YG-1 cobalt roughing end mills (e.g., MPN 60321) for rapid material removal in stainless steel and alloy steels.
Precision finishing — YG-1 TiN-coated HSS end mills (e.g., MPN 12059HN) for achieving tight tolerances on ferrous workpieces.

Frequently asked questions

Common questions about YG-1 from 3G Electric.

What materials are YG-1 cobalt end mills suitable for machining?

YG-1 cobalt end mills, such as the general-purpose square end mill MPN 04338 (cobalt, 6-flute, 5/8" diameter) and the ball end mill MPN 43297CC (cobalt, TiCN coated, 4-flute, 1/4" diameter), are designed for machining harder materials including stainless steels, titanium alloys, and high-temperature alloys. The cobalt content (typically 8% cobalt in M42 grade) provides increased hot hardness and wear resistance compared to standard HSS, making these tools effective in applications where heat generation is significant. They are also suitable for machining carbon steels and alloy steels at higher speeds than HSS tools.

What is the difference between YG-1 single-end and double-end end mills?

YG-1 single-end end mills have cutting edges on one end only, while double-end end mills have cutting edges on both ends, allowing the tool to be flipped when one end wears out. For example, YG-1 double-end HSS square end mills like MPN 13040 (4-flute, 9/64" diameter) and MPN 13048 (4-flute, 17/64" diameter) provide two usable cutting sections per tool, effectively doubling tool life per unit. Double-end tools are typically used in applications where tool change time is a factor, though they may have slightly shorter flute lengths compared to single-end equivalents of the same overall length.

What coatings are available on YG-1 end mills supplied by 3G Electric?

3G Electric supplies YG-1 end mills with various coatings, including TiN (titanium nitride) and TiCN (titanium carbonitride). For instance, the double-end HSS square end mill MPN 12059HN (4-flute, 13/32" diameter) has a TiN coating, which provides increased surface hardness and reduces friction. The cobalt ball end mill MPN 43297CC features a TiCN coating, which offers higher oxidation resistance and is suitable for machining abrasive materials. Uncoated HSS and cobalt tools are also available for general-purpose applications where coating is not required.

What flute configurations are available for YG-1 end mills from 3G Electric?

YG-1 end mills supplied by 3G Electric are available in 2-flute, 4-flute, and 6-flute configurations. For example, the double-end HSS square end mill MPN 50016HN (2-flute, 9/64" diameter) is designed for slotting and plunge cutting, while 4-flute tools like MPN 13040 are suitable for general milling and finishing. The 6-flute cobalt square end mill MPN 04338 provides a finer finish and is used for high-speed machining of harder materials. The choice of flute count affects chip evacuation, surface finish, and cutting speed.

What is the typical length of cut (LOC) range for YG-1 end mills at 3G Electric?

YG-1 end mills available through 3G Electric have lengths of cut ranging from 13/32" (approximately 10.3 mm) on smaller double-end tools like MPN 50016HN to 2" (50.8 mm) on larger single-end tools like MPN 07228. For example, the cobalt ball end mill MPN 43297CC has a 5/8" LOC, while the cobalt roughing end mill MPN 60321 has a 1-1/4" LOC. Overall lengths vary from 2-7/16" to 4-1/2", depending on the tool size and type.
