Grade H6310 cemented carbide indexable insert – applications and construction

double-sided 90° square with a hole and chip breaker

The SNMG 120404 turning insert is a double-sided, square indexable insert made of H6310 grade cemented carbide, designed for turning steel and stainless steel. The S shape, a square with a 90° corner angle, provides a short, rigid edge that withstands loads during longitudinal turning and facing. Negative geometry with a 0° clearance angle allows both sides of the insert to be used — a total of eight cutting edges. The nose radius rε 0.4 mm promotes finishing and precision machining at low feed rates. The hole with a chip breaker on both sides (type G per ISO 1832) controls chip flow and breaking.

Key advantages of the H6310 cemented carbide insert

  • Eight cutting edges — 4 corners 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.
  • Corner radius rε 0.4 mm — a finishing variant for low surface roughness at shallow depths of cut.
  • The 90° square corner provides rigid support in the pocket and withstands varying machining allowances and interrupted cuts.
  • Tolerance class M provides repeatable cutting edge positioning after indexing the insert in the holder pocket.
  • Dimensions conform to ISO 1832: side length 12.7 mm, IC 12.7 mm (1/2″), thickness 4.76 mm — compatible with holders with a 12 pocket.

Square insert applications and cutting data selection

The SNMG 120404 insert (also written without a space as snmg120404) is suitable for turning shafts, sleeves and flanges made of structural steels, as well as stainless steel components. The square shape provides rigid corner support, allowing the insert to withstand varying machining allowances and lightly interrupted cuts. 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. When machining stainless steels, maintain a constant feed and a cutting speed within the range in the table to avoid work hardening of the layer being cut.

H6310 is a PVD-coated carbide grade covering ISO P20-P40 and M20-M40 groups, allowing one insert to machine both structural steel and austenitic stainless steel. The 0.4 mm nose radius is a finishing variant and provides low surface roughness at feed rates up to 0.2 mm/rev without an additional pass. For roughing with a larger machining allowance, select an insert from the same SNMG 1204 family with a larger nose radius, which distributes cutting forces more effectively over a longer section of the edge. H6310 grade indexable inserts are supplied by the Korean brand Horn.

Application limitation

Grade H6310 is not intended for steels hardened above 45 HRC — for hard turning, choose a version with a cubic boron nitride cutting edge (CBN).

Frequently asked questions about the SNMG 120404 insert

use, turning tool selection, and turning parameters

Eight — a square has 4 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 square 12 pocket (IC 12.7 mm): for external turning, the families PSSNR/L, TSSNR/L and PSDNN, TSDNN (entering angle 45°) and PSKNR/L, TSKNR/L and PSBNR/L (75°) with shank cross sections of 20×20–32×32 mm; for internal turning, boring bars S25S–S50V and A25R/A32S with the suffix PSKNR/L or TSKNR/L.

Only in corner radius: 0.4 mm is a finishing variant for low feed rates, 0.8 mm is a general-purpose version, while 1.2 mm is selected for roughing with a larger machining allowance. The remaining dimensions (IC 12.7 mm, thickness 4.76 mm) are identical.

Yes — grade H6310 covers group ISO M20-M40. Maintain a constant feed, a cutting speed within the range in the table and continuous emulsion cooling: austenitic steel dissipates heat poorly and work-hardens when cutting too slowly.
