Electric Porcelain Thread Tapping Machine Tap

Special Ceramic Pre‑Sintered Solid Carbide Internal‑Coolant Machine Tap

Engineered for precision threading in hard, brittle materials such as electrical porcelain insulators, this tap combines a pre‑sintered ceramic overlay with a solid carbide body and internal coolant channels to deliver exceptional wear resistance, chip evacuation, and thread quality on CNC tapping machines.

Key Features

• Pre‑Sintered Ceramic Overlay + Solid Carbide Core
  A thin, fused ceramic layer on the cutting flutes offers outstanding hardness and abrasion resistance, while the carbide core provides rigidity and toughness for reliable machine use.

• Internal Coolant Channels
  Through‑tool coolant delivery flushes chips and controls heat directly at the cutting edge, extending tool life and ensuring consistent thread form.

• Optimized for Porcelain & Technical Ceramics
  Geometry and coatings are tailored to cut hard, non‑metallic insulator materials without cracking or chipping.

• High‑Precision Machine Use
  Straight‑flute design with ground tapping teeth delivers accurate thread pitch and minimal backlash at high spindle speeds.

Specifications

Applications

• Thread cutting in high‑voltage porcelain insulators and ceramic connectors

• Pre‑tapping of sintered ceramic components and hardened technical ceramics

• High‑volume CNC tapping operations requiring minimal downtime and maximum tool life

Benefits

• Extended Tool Life: Ceramic wear layer significantly reduces flank wear.

• Improved Surface Finish: Internal coolant ensures clean, burr‑free threads.

• Reduced Breakage: Carbide core provides shock resistance during high‑speed tapping.

• Versatile Use: Ideal for both through‑hole and blind‑hole ceramic threading tasks.
