55° RH and LH Tool Holders for Inserts w/7° Relief Angle

These holders are identical to our standard 55° Insert Tool Holders, with one key distinction.

While our original 55° holders are designed for DPMT inserts with an 11° relief angle, these updated holders are configured for DCMT inserts, which feature a 7° relief angle.

Over time, insert availability and design options evolve. The DPMT insert, once standard in our 55° holders, has become increasingly scarce and offers fewer chip breaker variations. In contrast, the DCMT insert is widely available and comes in a broad range of styles, making it a more versatile and accessible option.

Note: Many customers machining brass found excellent results with our uncoated 11° DPMT insert featuring a straight-groove chip breaker. Unfortunately, this insert is no longer available. That’s why we introduced these updated holders to accommodate 7° DCMT inserts.

For those working with brass, insert P/N 7613 is an ideal replacement. It cuts cleanly and delivers a high-quality surface finish.

Coated inserts with various chip breaker designs are still available for both DPMT and DCMT styles.
