4 Flute Square End Mill, 3/8 in dia, 7/8 in LOC, AlTiN Solid Carbide

The Titan USA TC29524 is a premium AlTiN-coated 4 flute solid carbide square end mill engineered for high-temperature milling of hardened steels, stainless steel, titanium, and heat-resistant alloys. The Aluminum Titanium Nitride (AlTiN) coating forms an aluminum oxide layer at elevated cutting temperatures, dramatically increasing thermal hardness and oxidation resistance for longer tool life at aggressive cutting speeds. The 3/8 in cutting diameter and 7/8 in length of cut make the TC29524 a versatile choice for slotting, profiling, and contouring in challenging materials that wear conventional uncoated tools quickly. AlTiN coating allows for dry machining or minimal lubrication in many applications, reducing coolant costs and improving machining efficiency. The 4 flute geometry provides superior surface finishes and higher material removal rates. Ideal for aerospace, automotive, and die/mold machining where difficult materials and extended tool life are critical requirements.

• AlTiN coating forms a protective oxide layer at high temps — extends tool life in hardened steels and titanium
• Supports dry machining or minimal lubrication, reducing coolant costs
• Outperforms uncoated tools in stainless steel, heat-resistant alloys, and exotic materials
• 4 flutes deliver superior surface finishes and higher material removal rates
• Engineered for aerospace, automotive, and die/mold applications with demanding materials
• Maintains cutting-edge hardness at elevated temperatures where uncoated carbide degrades
