Gold coated carbide end mill with four spiral flutes and square tip

YG-1 Tool Company

YG-1 Tool Company Carbide End Mill 7/16 Square 2in Cut Length 4 Flute TiN E5012

SKU CH-Y0Q5-NMJRT

A 7/16 inch square carbide end mill with 2 inch cut length, 4 flutes and TiN coating for steels and non-ferrous metals

  • Carbide construction handles high-speed milling in steel
  • 4-flute design improves chip evacuation and surface finish
  • TiN coating reduces friction and extends tool life
  • 30-degree helix angle balances cutting strength with smooth action
  • 2-inch cut length enables deeper profiling in a single pass

General-Purpose Carbide End Mill

This carbide end mill suits machinists and maintenance technicians who need a reliable square-end cutter for slotting and profiling. It handles mild steels, soft to medium-hard steels, stainless steels and non-ferrous metals in a single pass.

Replaces Worn or Lower-Flute Cutters

The jump is worth it when an existing tool shows flank wear, chipping or poor chip evacuation in the listed materials. A fresh four-flute geometry with TiN finish restores feed rates and surface finish without changing the tool path.

Straightforward Collet or Chuck Mounting

The 7/16 inch shank matches the cutting diameter for direct fit in standard holders. Common issues include excessive runout from worn collets, insufficient coolant on stainless grades and over-aggressive depth of cut causing deflection.

Questions about this item

What shank diameter does the 7/16 inch end mill need in a collet or holder?

The shank diameter is 7/16 inch, so use a matching 7/16 inch collet or end-mill holder for a secure fit.

How should the TiN-coated carbide end mill be installed to avoid runout?

Insert the shank fully into the holder, tighten the collet nut evenly, and verify the tool runs true before cutting; insufficient shank engagement causes vibration.

When should the TiN coating on this 4-flute end mill be considered worn and the tool replaced?

Replace the tool when the gold TiN coating has worn away at the cutting edges, when flank wear exceeds acceptable limits, or when surface finish degrades on mild or stainless steels.
