CoroTap overview A complete tapping programme

​With a complete tapping programme covering all thread profiles and material groups, Sandvik Coromant offers two tapping ranges: optimized for ISO-specific materials and optimized for flexibility. 

CoroTap™ optimized for ISO-specific materials is the solution for high batch quantities, when tapping the same component in the same material or when there are specific application requirements. 

CoroTap™ -XM optimized for flexibility is the solution when tapping small to medium batch quantities and when there is a variation of components in a wide range of materials. 

Benefits

• High productivity and long tool life
• Reduced machine downtime
• Highly efficient machining process
• Increased productivity through higher cutting speeds
• Optimum performance through material-specific designs and coatings  

CoroTap for flexibility:

• Suitable for a wide range of materials
• Reduces tool inventory and minimizes costs
• Provides long consistent tool life
• Offers a stable machining process due to unique cutting geometry
  

Depending on your specific hole requirements, there are four different CoroTap families.

CoroTap™ families

​	CoroTap™ 100 Taps with straight flutes Mainly used for short chipping materials like cast iron Suitable for both through and blind holes Flute mainly used for cutting fluid but with internal coolant, chip evacuation is also possible​
​	CoroTap™ 200 Taps with spiral point grinding Pushes the chips forward Used for through holes Strongest design due to shallow flutes Flute only used for cutting fluid, not for chip evacuation​
​	CoroTap™ 300 Taps with spiral flute grinding The spiral flute transports the chips out of the hole Best option for blind holes Different helix angle for different applications Flute used for both cutting fluid and chip evacuation Different threading depths due to application and geometry​
​	CoroTap™ 400 Taps that form the thread instead of cutting A chip-free solution All materials not suitable since there is need of certain ductility. Recom-mended tensile strength limit is 1200 N/mm2 For both through and blind holes Available with and without oil grooves​

​Recommendations

Use CoroChuck™ 970 for synchronized tapping as a first choice. The  versatile CoroChuck 970 is designed for a stable and precise tapping process in all materials. It improves tap tool life, surface quality and offers the highest process security. 

• Synchronized tapping reduces thrust force on tap flanks
• Accurate depth thanks to limited axial compensation
• Improved design for internal coolant
• Suitable for high pressure coolant up to 80 bar (1160 psi)
• More back-ends to fit your machine
