Frequently Asked Questions

What is a YG-1 square end mill used for?

A YG-1 square end mill is used for general-purpose milling of steel, stainless steel, and other ferrous materials. Its square profile creates flat-bottomed slots, shoulders, and pockets. The TiN coating reduces friction and heat, extending tool life in machining operations.

What are the specifications of the YG-1 01391CN end mill?

The YG-1 01391CN is a 7/8" diameter, 2-flute, TiN-coated cobalt square end mill with a 7/16" length of cut and 2-5/16" overall length. It is designed for general-purpose milling and is made from cobalt high-speed steel for improved wear resistance.

Where to buy YG-1 end mills worldwide?

3G Electric supplies YG-1 end mills worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine YG-1 cutting tools like the 01391CN square end mill to customers across multiple industries.

How to select the right YG-1 end mill for your application?

Select a YG-1 end mill based on material, coating, and geometry. For general milling of steel, a TiN-coated cobalt end mill like the 01391CN offers good heat resistance. Match flute count to operation: 2-flute for slotting, 4-flute for finishing. Always verify shank diameter and length of cut.
