Grade H6310 cemented carbide indexable insert – applications and construction

single-sided 55° diamond with a hole and chip breaker

The DCMT 070202 turning insert is a single-sided, diamond-shaped indexable insert made of H6310 grade cemented carbide, designed for turning steel and stainless steel. Shape D, a diamond with a 55° corner angle, facilitates access to the workpiece contour and machining of corners and undercuts. Positive geometry with a 7° clearance angle reduces cutting forces, making the insert suitable for slender shafts, boring, and smaller lathes. Two 55° corners on one side provide two cutting edges, while the rε 0.2 mm nose radius promotes smooth surfaces at low feed rates.

Key advantages of the H6310 cemented carbide insert

  • Two cutting edges — two 55° corners on one side of the insert; positive geometry prevents use of the other side, as is typical of 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 0.2 mm — for finishing and precision machining at low feed rates and with thin uncut chips.
  • The positive 7° clearance angle reduces forces and power consumption — suitable for slender workpieces and internal turning.
  • Dimensions per ISO 1832: edge length l 7.75 mm, IC 6.35 mm (1/4″), thickness s 2.38 mm — compatible with holders with a size 07 diamond-shaped pocket.
  • The 55° corner angle balances contour access and tip strength — smaller than 80°, larger than 35°.

Applications and cutting data selection for the diamond-shaped insert

The DCMT 070202 insert (also written without spaces as dcmt070202) is suitable for precision turning of shafts, bushings, and thin flanges made of structural steels, as well as stainless steel components. Calculate spindle speed using n = 1000·Vc/(π·D): for a shaft diameter of 40 mm at Vc = 200 m/min, the result is approximately 1592 rpm. For stainless steel, maintain a cutting speed of 70–230 m/min and a constant feed to limit work hardening of the layer being cut. H6310 grade indexable inserts are supplied by the Korean brand Horn.

The 0.2 mm nose radius and positive geometry make DCMT 070202 an insert for finishing and precision machining at shallow depths of cut and feed rates of approximately 0.03–0.11 mm/rev. For heavier roughing operations, choose an insert from the same DCMT 0702 family with a larger nose radius. The PVD coating on grade H6310 increases resistance to abrasive and adhesive wear, extending edge life when turning steel and stainless steel. The sharp, positive cutting edge reduces the tendency to form built-up edge, which is important when machining gummy materials and thin walls. These features make these inserts practical for turning precision parts on smaller machines.

Application limitation

Grade H6310 is not intended for steels hardened above 45 HRC — for hard turning, select a cubic boron nitride insert (CBN). The small nose radius 0.2 mm and positive geometry also limit the depth of cut — this is an insert for finishing operations, not roughing.

Frequently asked questions about the DCMT 070202 insert

use, turning tool selection, and turning parameters

Two — the 55° diamond has 2 corners per side, and positive geometry with a 7° clearance angle allows only one side of the insert to be used. Once both corners are dull, the insert is replaced with a new one.

Holders with a 07 diamond-shaped pocket (IC 6.35 mm): for external turning SDHCR/L, SDJCR/L and SDNCN with cross sections of 8×8–16×16 mm; for internal turning, boring bars S10K–S20R with the suffix SDUCR/L, SDQCR/L, SDPCR/L, SD-CR/L, or SDXCR/L. The full list is available in the compatible turning tools section.

Mainly in the nose radius: 0.2 mm is a version for precision finishing at low feed rates, while 0.4 mm is more versatile and has a stronger tip. The other dimensions (IC 6.35 mm, thickness 2.38 mm) are identical, so both inserts fit the same holders with a size 07 pocket.

Yes — grade H6310 covers group ISO M20-M40. Maintain a cutting speed of 70–230 m/min, a constant feed, and continuous emulsion cooling: austenitic steel conducts heat poorly and work-hardens when cutting is too slow.
