Turning heat-resistant super alloys (HRSAs) has always been a challenging prospect for the modern machine shop.

However, TaeguTec is now simplifying this challenge with the arrival of insert designations that have been added to its T-Turn turning series of cutting tools.
With a glossy yellow sheen, the PVD coated TT3010 grade is characterised by its high abrasion resistance and high bonding strength, which result from its ultra-fine substrate. In combination, this abrasion-resistant, high-bonding strength, ultra-fine substrate – and a special coated layer – enables chipping resistance to prevent built-up-edges. The grade is suited to low depths-of-cut finishing applications.
Alongside the TT3010 will be the new PVD coated TT3020 grade. This insert uses an ultra-fine substrate that is said to generate high abrasion resistance and toughness during machining. With a smooth coated layer surface manufactured through a special treatment process, the TT3020 demonstrates resistance to built-up-edges. For HRSA materials, this is TaeguTec’s most frequently recommended grade for the machining of scaled surfaces and light external applications in the low-to-medium speed range.
Both grades are available with two new chip breakers, MGS and FGS. The MGS chip breaker is a negative insert with a sharp cutting edge that reduces cutting resistance and heat generation during machining. In contrast, the FGS chip breaker is a positive insert that has a sharp cutting edge to generate low cutting resistance while guaranteeing precision machining. The chip breaker serves to minimise heat when machining high-temperature alloys.
