Making the Hard Easy with HardMill End Mills ( Jul. 01. 2014 )

Rule number one when machining high hardness materials is the harder the material, the greater the demands placed on the cutting tool.

To mitigate the negative effects on cutting tools brought on by reduced cycle times, TaeguTec has introduced HardMill, a new solid carbide end mill dedicated towards high-speed machining of high hardness materials.

With tougher application requirements demanded from the mold and die and automotive industries, TaeguTec has applied an advanced coating on the HardMill line grade, the TT5505, in order to improve on current offerings in the market right now. Its improved tool life and coating is a direct result of the ultrafine grain size substrate which, in the end, provides excellent surface finish.

While this is a dedicated cutting tool for high-speed machining of hardened workpieces, the end mill’s optimized shape gives the user levels of resistance to wear and tear that increases productivity and offers greater performance while at the same time, its superior radius and diameter tolerances enables for precise finishing operations.

TaeguTec’s new end mill is available in 645 standard items and comes in three types: flat, radius and ball nose types. The HardMill is also available in a wide selection of neck length covering a broad range of applications for the mold and die, automotive and general machining sectors.

A further advantage of the HardMill is its precision and stability due to its improved “R” accuracy and diameter tolerance.

The best solution for high-speed machining of high hardness steel from one of Asia’s metalworking leaders is accentuated by the PVD coated TT5505 grade, a new ultrafine substrate with resistance properties that improves tool life and offers excellent surface finish.

Real-world case studies against some of the biggest competitors in the business have found that TaeguTec’s HardMill series of flat, radius and ball nose types have substantially increased tool life.
