Powder HSS-Co Spiral Flute Taps Set 7pcs With TiAlN Coating

This product is a 7-piece professional spiral flute tap set, made of high-quality powder HSS-Co (high-speed steel with cobalt) and coated with TiAlN. It integrates high hardness, wear resistance and corrosion resistance, suitable for tapping internal threads in various metal materials, widely used in machinery manufacturing, auto parts processing, hardware processing and other professional scenarios, as well as the needs of senior DIY enthusiasts.

Core Product Advantages

1. High-Quality Powder HSS-Co Material

Adopting advanced powder metallurgy technology, the taps are made of HSS-Co material, which has higher hardness, toughness and wear resistance than ordinary high-speed steel. The added cobalt element enhances the red hardness of the taps, enabling them to maintain stable performance even at high temperatures during tapping, reducing wear and extending service life.

2. TiAlN Coating for Enhanced Performance

Each tap is coated with TiAlN (Titanium Aluminum Nitride), which features high hardness, low friction coefficient and excellent corrosion resistance. The coating effectively reduces the friction between the tap and the workpiece, prevents chip adhesion, improves tapping efficiency and surface quality of internal threads, and also protects the tap from oxidation and corrosion.

3. Spiral Flute Design for Smooth Chip Removal

The taps adopt a spiral flute design, which can smoothly discharge chips generated during tapping, avoid chip clogging in the flute, reduce tapping resistance, prevent tap breakage, and ensure smooth and stable tapping process. The spiral angle is scientifically designed to adapt to different tapping materials and improve tapping efficiency.

4. 7-Piece Complete Set, Wide Application

The set includes 7 common specifications of taps, covering M3 to M12, which can meet most daily and professional tapping needs. The taps comply with DIN371/376 standards, with precise thread pitch and high tapping accuracy, ensuring that the processed internal threads are uniform and firm, suitable for tapping various metals such as carbon steel, alloy steel, stainless steel and cast iron.

Application Scenarios

Widely used in professional fields such as machinery manufacturing, auto parts processing, hardware processing, mold making and instrument manufacturing. It is also suitable for senior DIY enthusiasts to carry out home maintenance, hand-made production and other tapping operations, which can effectively improve tapping efficiency and quality.

Core Product Parameters

Usage Notes

1. Check the tap for damage, wear or coating peeling before use, and replace it in time if any abnormality is found;

2. Select the appropriate tap according to the workpiece material and thread specification, and use tapping oil during operation to reduce friction and extend tap life;

3. Control the tapping speed and feed rate properly to avoid excessive speed leading to tap overheating or breakage;

4. After use, clean the tap in time to remove chips and cutting oil, and store it in a dry and clean place to prevent rust;

5. Do not use the tap beyond its applicable material range, and avoid forced tapping to prevent tap damage.
