1/2" Carbide Thread Milling Cutter Customized Coolant Through End Mill Rc 3/8

Rc 3/8 Coolant Through Custom Thread Endmill CNC Alloy Cutting Tools

Introduction:

This custom-designed coolant-through thread end mill is engineered for precision machining of Rc 3/8-19 BSPT (British Standard Pipe Taper) threads in high-performance alloys (stainless steel, titanium, Inconel, etc.). The internal coolant channels ensure superior chip evacuation, thermal management, and extended tool life in demanding applications.

Key Features:

✔ Thread Standard: Rc 3/8-19 BSPT (ISO 7-1 / BS 21)

✔ Material: Ultra-fine grain solid carbide for extreme wear resistance

✔ Coolant Design: High-pressure through-tool coolant (2-4 jets, 0.8-1.2mm holes)

✔ Coating Options:

• TiAlN (best for steel & stainless steel)

• AlCrN (for high-temp alloys like Inconel)

• DLC (Diamond-Like Carbon) (for non-ferrous & sticky materials)
  ✔ Flute Geometry:

• 4-6 flutes (balanced between chip space & rigidity)

• Variable helix for reduced vibration in tough alloys

Advantages:

✅ 50%+ longer tool life in alloys due to efficient cooling

✅ No chip recutting – Coolant flushes chips from deep threads

✅ Tighter tolerances (ISO 2H/4H thread fit) from reduced thermal expansion

✅ Single-tool solution for roughing & finishing in hardened materials

Typical Applications:

• • • Aerospace hydraulic fittings (Ti-6Al-4V, 17-4PH SS)

• • • Oil & gas subsea connectors (Inconel 718, Duplex SS)

• • • Medical implant threads (CoCr, 316L SS)

• • • High-performance automotive systems (Al-Si alloys, hardened steels)
