TANGFACE MAHPR-XL-...-JHP-MC & TNFPAD-XL ...R/L-...-JHP
A new range of tools and adapters for deep face grooving operations is introduced with the following advantages

• Reinforced design enables deep face grooving operation with excellent stability
• Great chip evacuation with less chip jamming due to the JETCUT coolant option
• Can be used with low pressure coolant up to high pressure of 140 Bar
• Cooling hole pinpointed to the cutting edge reduces built up edge and improves tool life
• Available for standard TNF inserts 4, 5 and 6mm width
• Designed for face grooving depths from 20 - 50mm and diameters from Ø35 -Ø315mm
