Product Overview

Our metric solid carbide straight flute taps are engineered for high-precision internal threading in a wide range of materials, especially non-ferrous metals, cast iron, and hardened steels up to HRC 55. Manufactured from ultra-fine grain tungsten carbide, these taps provide exceptional wear resistance, rigidity, and dimensional accuracy, making them ideal for CNC high-speed tapping and precision machining applications.

The straight flute design ensures stable chip evacuation in short-threaded blind holes and through-holes, particularly in materials that produce short, broken chips like cast iron and aluminum alloys.

Key Features

• Metric Thread Standards: Compatible with ISO metric pitch (coarse and fine)

• Solid Carbide Construction: Superior hardness and heat resistance

• Straight Flute Geometry: Ideal for short-chip materials and high-rigidity tapping

• High Thread Accuracy: Achieves 6H/6G class internal threads

• Optimized for CNC Machines: Designed for high-speed, high-precision threading

Applications

• Threading cast iron, aluminum alloys, brass, copper, and plastics

• Hardened steel components (up to HRC 55) such as dies, molds, and tooling plates

• High-volume automotive, aerospace, mold making, and electronics industries

• Suitable for blind holes and through-holes with stable chip control

Advantages

• Ultra-long tool life in abrasive or hard materials

• Maintains tight tolerance threading across thousands of cycles

• Ideal for automated CNC tapping, minimizing downtime

• Excellent performance in non-ferrous and brittle materials

• Chip control stability for blind and through holes

Usage Recommendations

• Use tapping oil or minimum quantity lubrication (MQL) for best performance in hard metals

• Suitable for rigid tapping cycles on CNC machines

• For high-speed applications, adjust feed rate to avoid overloading the tap

• Ensure pre-hole diameter follows recommended drill size for the thread pitch
