One-Step Threading with High Precision and Speed
The Solid Carbide Spiral Flute Drill-Tap Combo Tool is a high-efficiency, all-in-one cutting solution designed to drill and tap threads in a single pass. Engineered from premium tungsten carbide, this combination tool reduces machining time, improves alignment accuracy, and is ideal for automated CNC operations, especially in high-volume production environments.
Equipped with a spiral flute geometry and precision-ground thread section, this tool ensures excellent chip evacuation, minimal tool deflection, and clean internal threads, even in blind holes. It is particularly effective for materials such as aluminum, copper, non-ferrous alloys, and mild steels.
2-in-1 Functionality: Performs both drilling and tapping in a single operation
Material: Ultra-fine grain solid tungsten carbide for superior wear resistance
Spiral Flute Design: Ensures efficient chip removal and smooth threading
High Precision: Tight tolerance control for thread accuracy and consistency
Ideal for CNC Machining: Reduces cycle time and tool changes
Ideal for high-efficiency threading in blind or through holes
Used in electronics casings, aerospace parts, aluminum components, and precision mechanical assemblies
Compatible with aluminum, brass, copper, plastics, and mild steels
Suitable for vertical/horizontal CNC machines, robotic arms, and multi-axis machining centers
Streamlined workflow – Drill and tap without changing tools
Consistent, clean threads – No secondary tapping needed
Reduced machining time – Up to 50% faster than traditional methods
Enhanced accuracy – Drill and tap alignment in one setup
Long tool life – Durable carbide body withstands high cutting loads
Ensure proper RPM/feed rate calibration based on material and size
Use appropriate coolant or MQL to improve surface finish and reduce tool wear
Designed primarily for ductile or soft metals – not recommended for hardened steel
For blind holes, verify that thread depth doesn’t exceed flute length
