Grade H6310 cemented carbide indexable insert – applications and construction
double-sided 80° trigon with a hole and chip breaker
The WNMG 060408 turning insert is a double-sided, trigon-shaped indexable insert made of grade H6310 cemented carbide, designed for turning steel and stainless steel. Shape W, a trigon with a 80° corner angle, combines tip strength similar to that of a square insert with better access to the workpiece contour. Negative geometry with a 0° clearance angle allows both sides of the insert to be used — a total of six cutting edges. The nose radius rε of 0.8 mm balances surface finish with edge durability at feed rates of 0.15–0.3 mm/rev. A hole with a chip breaker on both sides (type G according to ISO 1832) controls chip flow and breaking during longitudinal turning.
Key advantages of the H6310 cemented carbide insert
- Six cutting edges — 3 corners at 80° on each of the two sides reduce the cost per cutting edge compared with single-sided inserts.
- Grade H6310 for ISO groups P and M — general-purpose PVD-coated carbide: steel (P20-P40) and stainless steel (M20-M40), and occasionally cast iron.
- Included angle 80° — the strong trigon tip handles greater depths of cut than rhombic inserts with a sharper corner.
- The nose radius rε of 0.8 mm is a general-purpose version — semi-finishing without changing the insert between roughing and finishing passes.
- Tolerance class M, with an inscribed circle IC tolerance of ±0.05 mm, ensures repeatable cutting edge positioning after indexing the insert in its pocket.
- Dimensions according to ISO 1832: IC 9.525 mm (3/8″), thickness 4.76 mm, ANSI code WNMG 332 — fit holders with a W trigon pocket.
Applications and cutting data selection for the trigon insert
The WNMG 060408 insert (also written without a space as wnmg060408) is suitable for longitudinal turning and facing of shafts, bushings and flanges. It machines structural steels and stainless steel components. Calculate spindle speed using n = 1000·Vc/(π·D): for a shaft diameter of 50 mm at Vc = 250 m/min, the result is approximately 1592 rpm. The large 80° corner angle strengthens the insert tip, allowing it to withstand a greater depth of cut than inserts with sharper corners. It is a good choice for general-purpose work and light roughing.
When machining stainless steels, maintain a cutting speed in the range of 50–230 m/min and a constant feed rate to reduce work hardening of the layer being cut and built-up edge. The PVD (physical vapor deposition) coating of grade H6310 increases the edge's resistance to wear and oxidation. This extends cutting edge life between indexing operations in the pocket. The double-sided chip breaker keeps chips short and controlled even with varying stock allowances, facilitating operation on automatic lathes without constant operator supervision. Grade H6310 indexable inserts for series production are supplied by the Korean brand Horn.

Application limitation
Grade H6310 is not intended for steels hardened above 45 HRC — for turning inserts for hardened steel, choose version WNMG 060408 CBN with a cubic boron nitride cutting edge.

Frequently asked questions about the WNMG 060408 insert
use, turning tool selection, and turning parameters
Six — the trigon has 3 corners per side, and the negative geometry (0° clearance angle) allows both sides of the insert to be used. Once an edge becomes dull, simply rotate the insert in its pocket without changing the holder.
Holders with a trigon pocket for a W insert (IC 9.525 mm): for external turning TWLNR/L and MWLNR/L (entering angle 95°) and MWDNN (45°) with shank cross sections of 16×16–25×25 mm; for internal turning, boring bars S16P–S32T with a TWLNR/L or MWLNR/L head.
Only in corner radius: 0.4 mm is used for finishing at low feed rates, 0.8 mm is the general-purpose version, and 1.2 mm is selected for roughing at higher feed rates. The remaining dimensions (IC 9.525 mm, thickness 4.76 mm) are identical.
Yes — grade H6310 covers group ISO M20-M40. Maintain a cutting speed of 50–230 m/min, a constant feed, and continuous emulsion cooling: austenitic steel conducts heat poorly and work-hardens when cutting is too slow.
