NPT BSPT 4 Flutes Thread Endmill Cutter 1/2" Solid Carbide Milling Tools

Introduction:

This 4-flute solid carbide thread end mill is designed for precision machining of NPT (National Pipe Taper) and BSPT (British Standard Pipe Taper) tapered pipe threads in various materials, including steel, stainless steel, aluminum, and cast iron.

Key Features:

Thread Type: Compatible with 1/2"-14 NPT and 1/2"-14 BSPT tapered pipe threads

Material: Solid carbide for high rigidity, wear resistance, and long tool life

Flute Design: 4 flutes for balanced cutting performance and chip evacuation

Coating Options:

• Uncoated (for general use)

• TiAlN/TiCN coated (for harder materials like stainless steel)

• Polished flutes (for aluminum/soft metals to prevent material buildup)

✔ Taper Angle: Matches standard pipe taper (1°47' for NPT, 1°47' or 1:16 for BSPT)

✔ Right-hand cutting (standard)

Advantages:

✅ Higher accuracy – CNC-controlled thread milling ensures tight tolerances

✅ Longer tool life – Carbide resists wear better than HSS taps

✅ Flexibility – One tool can machine multiple thread depths

✅ Better chip control – 4-flute design improves chip evacuation

Typical Applications:

• • Hydraulic & pneumatic fittings

• • Oil & gas pipe connections

• • CNC-machined flanges & couplings

• • High-precision tapered thread milling
