Carbide Straight Flute Tap

Our Quality Carbide straight flute tap is a premium machine tap designed for ISO metric and UNC/UNF threads. Engineered for both through-hole and blind-hole applications, it offers thread accuracy up to IT6–IT8 and surface finish as low as Ra1.6μm. Its straight flute design ensures smooth chip evacuation, excellent rigidity, and high stability. Made from ultra-fine carbide, it is ideal for hard-to-machine materials such as carbon steel, stainless steel, aluminum, cast iron, and hardened steels, covering sizes from M0.8 to M30. Compared to conventional HSS taps, Wangdefu carbide taps offer three times the tool life, lower downtime, and more efficient production.

Technical Specifications

What are the features of this product?

Ultra-Hard Carbide Core + High-Performance Coating Wangdefu’s Durable Carbide straight flute tap uses ultra-fine carbide with HRA92+ hardness and ≥3200MPa bending strength. Optional coatings like TiCN and TiAlN improve wear resistance and heat tolerance. For challenging materials such as cast iron, aluminum alloys, and HRC48+ hardened steels, tool life is increased by 3x compared to uncoated taps.

Straight Flute Design for Smooth Chip Removal The axial straight flute allows short, powder-like chip evacuation, reducing clogging and preventing tap breakage. Internal coolant channels provide efficient cooling, making it ideal for blind-hole operations and high-volume production.

Precision Ground Cutting Edge Five-axis precision grinding ensures accurate thread profile and smooth rounded cutting edges. Dimensional consistency across batches exceeds 98%, ensuring high-precision assembly for automotive, aerospace, and precision machinery components.

Wide Compatibility & Cost Efficiency Carbide straight flute taps are suitable for CNC machining centers, lathes, and tapping machines, supporting coarse and fine thread machining of various pitches and sizes. They reduce tool changes and the risk of tool breakage, potentially lowering machining costs by up to 40%.
