Mongtec PSC turning tool bodies by ISO 5608 style

357 article numbers across 50 tool styles, in coupling sizes PSC32 to PSC100 (Capto^®-size C3 to C10). Every style has its own page with the designation decoded, the approach angle, the insert it takes, and the full size range. Source: Mongtec PSC Product Catalog, Ver 2026.07. Mongtec Precision is a Taiwanese brand, designed and engineered in Taichung, Taiwan.

Reading a Mongtec PSC article number

Every code is built the same way, so once you can read one you can read all of them:

Block	Example	What it is
1	PSC50	Polygon shank coupling size per ISO 26623 — here equivalent to coupling size C5 and to PSK C5
2	DCLNR	ISO 5608 tool style: clamping system, insert shape, approach angle, insert clearance angle, cutting direction
3	35060	Functional cross-section and functional length in millimetres (35 mm × 60 mm)
4	12	ISO insert size

External turning tool bodies — 42 styles

Bodies that mount in the turret or spindle and turn the outside diameter, face and shoulders.

Internal turning / boring bar bodies — 8 styles

Bodies for boring and internal profiling, where reach and the minimum bore you can enter decide the choice as much as the insert does.

The coupling size is the one thing that must be right. PSC is a self-locking polygon taper — the wrong size will not clamp at all. Approach angle, reach and insert grade we can work out with you from the part drawing; the coupling we verify from the machine before quoting. Send the machine model if the size is not stamped where you can see it.

Frequently asked

Which PSC turning tool styles does Mongtec publish?

Mongtec publishes 357 PSC turning tool body article numbers across 50 ISO 5608 tool styles, split into 42 external turning styles and 8 internal turning / boring bar styles, in coupling sizes PSC32 through PSC100.

How do I read a code like PSC50-DCLNR-35060-12?

PSC50 is the polygon shank coupling size per ISO 26623, equivalent to coupling size C5. DCLNR is the ISO 5608 tool style: D is the clamping system, C is the insert shape (80 degree rhombic), L gives a 95 degree approach angle, N is the insert clearance angle (0 degrees, negative insert) and R makes it right hand. 35060 is the functional cross-section and length in millimetres, and 12 is the ISO insert size.

Is PSC the same as Coromant Capto?

PSC is the polygon shank coupling standardised in ISO 26623 and is an open standard that any manufacturer may build to. The sizes correspond dimensionally to coupling sizes C3, C4, C5, C6, C8 and C10 and to the German PSK designation. Mongtec Precision is an independent tooling brand and is not affiliated with, endorsed by or a licensee of Sandvik Coromant.

Do you publish dimensioned drawings?

No. Mongtec supplies the full dimensioned drawing by email once an enquiry is open, so the drawing matches your actual machine and coupling.
