YG-1 Carbide End Mill 5011

The YG-1 Tool Company carbide end mill 5011 is a square, single-end cutter with a 3/4 inch diameter and shank. Its 2-1/4 inch length of cut and 30 degree helix suit general-purpose milling in mild steels, stainless steels and non-ferrous metals.

Replaces worn or undersized square end mills

This tool upgrades from dull or smaller-diameter cutters when slots, pockets or drilled holes need a 3/4 inch profile. The jump is worth it for shops cutting hardened alloys, steel castings or brass where a fresh TiN finish extends edge life.

Holds dimension in extended cuts

The 5 inch overall length and two-flute design evacuate chips efficiently during deep slotting or pocketing. Center-cutting geometry allows direct plunging, while the TiN coating resists heat buildup across stainless steels, malleable cast iron and copper alloys.

Questions about this item

What shank diameter is required for the 3/4 in carbide end mill to fit a tool holder?

The shank diameter is 3/4 in, so a matching 3/4 in collet or end-mill holder is needed for secure clamping.

How should the TiN-coated 2-flute end mill be installed to avoid run-out?

Insert the shank fully into a clean, matched 3/4 in holder, tighten evenly, and verify concentricity before cutting to prevent vibration.

When will the TiN coating on this 30-degree helix cutter need replacement?

The TiN layer wears gradually; replace the tool once the gold coating is gone at the cutting edges or when cut quality drops on mild steel or aluminium.
