SumiTurn X-Bar - Anti-vibration boring bars

Amazing anti-vibration capabilities provide low cost, high efficiency and deep-hole boring operations

Precaution

Clamping on labeled portion may prevent the tool from working correctly (due to the built-in anti-vibration mechanism). Therefore, minimum tool overhang should be 3.5D.

1. Achieves 6D deep hole boring for ø32mm or more.
2. Negative type insert reduces the per corner cost.
3. Coupled with a wide selection of chipbreakers to cover a wide range of applications from roughing to finishing.

Cutting Conditions	vc=20 to 200m/min, f=0.1 to 0.3mm/rev, ap=0.1 to 2.0mm

*Actual tool overhang amount may change depending on work material, tool geometry, machining conditions, etc.
