With the combination of the premium powderHSS (characterized by high abrasion resistance and heat resistance) and the special coating, tool life has increased 5 times compared with the conventional tap designed for aluminum. ●Cutting edge damage diminishes on the flutes. Dimensional change in the internal thread pitch diameter is reduced while surface finishes are improved. ● Suitable from medium to high speed by offering the optimal coCmombpairinsoan tofiotonol lifoe fbetnweeegn AaXtEivaned LAra-Ok(pereviaouns gproleducat )nd eccentric relief. ⑥ Tapping Data AXE-HT AXE-HT and the LA-O (conventional product) 40,000 Processing condition [M8 × 1.25] Can Continue AXE-HT HSS-P special coating LA-0 7,000 ⑦ LA-O HSS-E NI surface treatment 0 10,000 20,000 30,000 40,000 Workpiece Material AC4A-T6 (Number of holes processed) Bored Hole Size φ6.8 Tapping Length 13mm blind hole Change in internal thread pitch diameter.
