Product Overview

Our solid carbide straight flute taps with UNC and UNF threads are engineered for precision internal threading in brittle, abrasive, or hard materials, such as cast iron, non-ferrous metals, plastics, and composites. These taps are manufactured from ultra-fine grain tungsten carbide, offering superior hardness, thermal resistance, and edge stability — ideal for CNC machining and rigid tapping.

Designed with straight flutes, this tap ensures controlled chip flow and clean thread cutting, especially effective in short chipping materials or when tapping through holes.

Key Features

• Thread Type: Unified Inch Standards – UNC (coarse) & UNF (fine) threads

• Solid Carbide Material: Ultra-hard, wear-resistant, and long-lasting

• Straight Flute Geometry: Ideal for through holes and short-chipping materials

• Thread Class: 2B / 3B internal thread tolerance (precision tapping)

• Rigid Tapping Ready: Perfect for CNC machining centers and automated production

Applications

• Tapping cast iron, aluminum alloys, copper, brass, and engineering plastics

• Used in aerospace, automotive, electronics, mold making, and precision machining

• Ideal for through holes or shallow blind holes in abrasive or brittle materials

• Recommended for high-speed tapping with minimal chip interference

Advantages

• High wear resistance in abrasive or tough-to-machine materials

• Produces accurate, consistent thread profiles with minimal burr

• No chip clogging in short chipping or brittle materials

• Excellent for automated high-speed production lines

• Reduced tap breakage risk due to superior rigidity and edge sharpness

Usage Recommendations

• Use cutting fluid or mist lubrication for better finish and tap longevity

• Pre-drill holes to the recommended minor diameter for best thread quality

• Avoid using on ductile materials that generate long chips – consider spiral taps instead

• Ideal for rigid tapping mode on CNC or high-precision machines
