1)   PM POWDER METALLURGY HIGH SPEED STEEL – High Performance Taps :
Powder Metallurgy High Speed Steel Grade is Premium Steel Engineered For Hardness , Wear Resistance , Tool Life , Heat Resistance , Toughness , Strength and Performance Under Difficult Cutting Conditions with Higher Cutting Speeds for Increased Productivity

Application :
  • ALLUMINIUM :    Recommended for all types of aluminum alloys.
  • EXOTIC ALLOYS :    Recommended for steels, steel alloys, stainless steels, titanium alloys, nickel and nickel base alloys, other exotic alloys
  • HARD MATERIALS :   Recommended for harder (32Rc-45Rc) materials including steel alloys, titanium alloys, nickel base high temperature alloys, tool and mold steels, and stainless steels.
  • CAST IRON :    Recommended for all types of gray, ductile and malleable cast iron
 
     
ET has started manufacturing high performance taps in superior grade powder metallurgy high speed steel. ET is now maintaining stock of superior grade powder metallurgy high speed steel taps in all standard sizes, mainly in Metric sizes ranging from 3 mm to 14 mm. These taps are available in the following varieties:

  • Fluteless Taps for blind & through hole in ductile materials.
  • Spiral Pointed Taps for through hole application
  • C.I. Taps for Cast Iron applications.
  • Spiral Fluted Taps for Blind hole application.
We are also manufacturing different varieties in superior powder metallurgy high speed steel for user-specific applications on request.

2)   CARBIDE TAPS :
The structure of carbide is very stable with consistent sub-micro grain particles and hard in nature with character more resistant to abrasion, pressure, heat, and material adhesion. Carbide is more brittle, therefore contributory factors to success or failure may comprise of the following: rigid work piece - rigid tapping avoiding shock or undesirable "float" - vibration. Carbide Taps offers a longer/faster and more consistent performance in specific application.

Application
  • High volume production in materials with abrasive qualities like cast iron and aluminum - silicon alloys (Si > 10%).
  • Materials which exhibit high wear characteristics or a "closing" nature. Composites - pure alloys such as tungsten, copper, etc - "exotics" - iron - alum alloys.
  • Materials hardened above Rc40. Steels and "exotic" alloys.

ET has started manufacture of Carbide Taps and at the moment are manufacturing different varieties of Carbide Taps against specific requests from customers.

3)   THROUGH COOLANT TAPS (T.C.H) :
The performance of taps with through coolant holes is higher than the same taps used with external lubrication. These kinds of taps allow better evacuation of the chip, which is transported away from the cutting area itself. Wear on the cutting edge is reduced, since the cooling effect on the cutting zone is higher than the heat generation. TCH taps give excellent performance while tapping deep blind holes up to 3xD. The advantage of T.C.H taps over conventional machine tap is increased tool life and a reduction in cycle times, cleaner cut threads, accurate dimensions, increased production with more tapped holes per tool resulting in lower machining cost per part.

Lubrication can be oil, emulsion or air pressurized with oil mist. Working pressure not less then 12 - 15 bar is required.

Application
T.C.H Taps is used for a variety of challenging applications involving tough, abrasive materials.

  • Through Coolant Taps with Axial hole  :    For blind hole tapping.
  • Through Coolant Taps with Radial holes: :    For through hole tapping.

ET has started manufacturing T.C.H high performance taps in HSS-E and superior grade PM- Powder Metallurgy high speed steel. These taps are available in the following varieties:

  • Fluteless Taps for blind & through hole in ductile materials.
  • Spiral Pointed Taps for through hole application
  • C.I. Taps for Cast Iron applications.
  • Spiral Fluted Taps for Blind hole application.

ET at the moment is manufacturing different varieties of T.C.H taps against specific requests from customers.
