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

Introduction:

This 6-flute solid carbide T-slot end mill is designed for precision machining of T-shaped grooves, slots, and undercuts in hardened steel, aluminum, and other metals. Made from high-grade tungsten carbide (YG8), it ensures exceptional hardness, wear resistance, and long tool life. The optimized 6-flute design enhances cutting stability and efficiency, making it ideal for CNC machining centers, milling machines, and industrial routers.

Available in multiple shank sizes (6mm, 8mm, 10mm, 12mm), this T-slot cutter is widely used in mold making, aerospace, automotive, and general metalworking applications.

Features:

✔ Premium Tungsten Carbide Construction – Ultra-hard material (up to HRC55 hardness) ensures long-lasting durability in demanding machining conditions.

✔ Optimized 3-Flute Design – Provides superior chip clearance vs. 4/6-flute end mills, reducing heat buildup and preventing chip clogging in aluminum and steel.

✔ High-Precision Grinding – Razor-sharp cutting edges deliver smooth finishes (±0.01mm tolerance) and minimize burrs.

✔ Versatile Coating Options – TiAlN coating (for steel) enhances heat resistance; uncoated/polished (for aluminum) prevents material 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, offering flexibility for different CNC setups.

Advantages:

✅ Efficient Chip Evacuation – 3-flute design prevents clogging in gummy materials like aluminum.

✅ Rigid & Stable Cutting – Reduced vibration vs. 2-flute end mills for better surface finish.

✅ Cost-Effective – Longer tool life reduces downtime and replacement costs.

✅ Multi-Material Compatibility – Works on steel, aluminum, brass, plastics, and composites.

Typical Applications:

• T-Slot Machining – Cutting T-grooves in machine tables, fixtures, and workholding systems.

• Steel & Hardened Alloys – Ideal for mold/die cavities, tool steels (H13, P20), and stainless steel.

• Aluminum & Non-Ferrous Metals – High-speed cutting with excellent surface finish (Ra≤0.8μm).

• General CNC Milling – Slotting, profiling, and pocketing in vertical/horizontal machining centers.
