SPB326 Parting Tool Holder

The SPB326 is a durable parting tool holder designed for CNC and conventional lathes. Engineered for stability and precision, it is specifically made to hold indexable parting inserts from the SP-series (such as SP300 and SP400). Its robust design allows reliable parting-off and external grooving with consistent accuracy and surface finish.

With its rigid blade-style construction, the SPB326 provides strong clamping of the insert, ensuring reduced vibration and excellent chip evacuation during cutting. The design enables deeper parting and grooving compared to smaller models like SPB226, making it suitable for medium to heavy-duty applications.

The SPB326 is commonly used in automotive, general machining, and heavy engineering industries, where productivity and tool life are critical. When combined with the correct SP-series inserts, it delivers stable performance for steels, stainless steels, and alloys.
