2 Flute Solid Carbide Square End Mill for Steel HRC55 - AlTiN Coated

High-performance 2 flute solid carbide end mill for steel (HRC55). Features AlTiN coating and large chip gullets for efficient slotting and plunging. Sizes 1mm to 12mm.

2 Flute Solid Carbide End Mill for Steel (HRC55)

Engineered for heavy slotting, plunging, and general milling, this 2-Flute Solid Carbide End Mill series is your go-to tool for machining Carbon Steel, Alloy Steel, and Pre-hardened Steel up to 55 HRC.
Featuring a premium AlTiN (Aluminum Titanium Nitride) coating, these cutters offer superior heat resistance and tool life compared to standard TiN coated tools. The 2-flute design provides ample space for chip evacuation, making it ideal for deep vertical cuts and slotting operations where chip clogging is a major concern.

Key Features & SEO Benefits

  • Optimized for Slotting: The large chip gullet design of the 2-flute geometry ensures rapid chip removal, preventing breakage during full-width slotting and plunging.
  • AlTiN Coating: Dark-grey/black high-performance coating withstands high cutting temperatures, extending tool life in hardened materials.
  • High Rigidity Design:

Why Choose 2-Flute Over 4-Flute?

While 4-flute end mills provide a better surface finish, 2-flute end mills are essential when chip clearance is the priority. If you are cutting slots or machining soft/gummy steels where chips tend to pack, the 2-flute design allows chips to escape freely, preventing the tool from snapping.
