Product Overview

Our solid carbide spiral flute taps with Unified thread profiles (UNC/UNF) are purpose-built for blind hole threading in materials that are tough, ductile, or require superior chip evacuation. With a left-hand spiral design, these taps lift chips upward and out of the hole, ensuring smooth, burr-free thread formation and reduced tap breakage. Ideal for use in precision CNC operations, especially in aluminum, stainless steel, carbon steel, and non-ferrous alloys.

Crafted from ultra-fine grain tungsten carbide, these taps offer maximum tool life, edge stability, and thermal resistance, making them ideal for high-speed tapping environments with demanding thread quality requirements.

Key Features

• Thread Standard: Unified threads – UNC (coarse) and UNF (fine)

• Spiral Flute Design: Optimized for blind holes and efficient chip evacuation

• Solid Carbide Substrate: Ensures high rigidity, minimal deflection, and long wear life

• Sharp Cutting Edges: Precision-ground flutes enable clean and consistent threads

• Excellent Performance in Ductile Materials: Ideal for aluminum, brass, stainless steel, and carbon steel

Applications

• Threading blind holes in aerospace, automotive, medical device, and electronic component manufacturing

• Tapping in CNC machining centers or automated production lines

• Suited for aluminum alloys, mild steel, alloy steel, and non-ferrous metals

• High-reliability threading in parts that require uniform thread depth and finish

Advantages

• Superior chip evacuation reduces tap breakage in deep blind holes

• Clean, precise threads even in sticky or soft metals like aluminum

• Performs exceptionally in high-speed and dry cutting environments

• Stable thread profile with less torque variation during tapping

• Available in both standard sizes and custom geometries upon request

Usage Recommendations

• Ensure correct pilot hole diameter and drilling depth

• Use lubrication (cutting oil or MQL) to reduce friction and extend tool life

• Ideal for use with rigid tapping cycles on CNC machinery

• Avoid in extremely abrasive or brittle materials — consider straight flute for those cases
