3 Flute Carbide TSlot End Mill for Steel Aluminum T Type Groove Router Bit CNC Milling Cutter 1/4" 3/8" 1/2" Shank

This 6-flute solid carbide T-slot end mill is engineered for precision machining of T-shaped grooves, slots, and undercuts in hardened steel, aluminum, and other metals. Constructed from high-grade tungsten carbide (YG8), it delivers exceptional hardness, wear resistance, and extended tool life.

• Premium Tungsten Carbide Construction - Ultra-hard material (up to HRC55 hardness) ensures long-lasting durability in demanding machining conditions.
• Optimized 3-Flute Design - Superior chip clearance reduces heat buildup and prevents clogging in aluminum and steel.
• High-Precision Grinding - Razor-sharp cutting edges deliver smooth finishes (±0.01mm tolerance) with minimal burrs.
• Versatile Coating Options - TiAlN coating for steel enhances heat resistance; uncoated/polished version prevents aluminum adhesion.
• Anti-Vibration Geometry - Reinforced core design reduces chatter during deep slotting and side milling.
• Multiple Shank Sizes - Compatible with 1/4", 3/8", and 1/2" collets/chucks for flexible CNC setups.

• T-Slot machining in machine tables, fixtures, and workholding systems
• Mold/die cavities, tool steels (H13, P20), and stainless steel
• High-speed aluminum cutting with excellent surface finish (Ra≤0.8μm)
• General CNC milling including slotting, profiling, and pocketing
