Positive diamond-shaped H6310 carbide insert – applications and design

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

The DCMT 11T302 turning insert is a single-sided, diamond-shaped indexable insert made of grade H6310 cemented carbide, designed for finish turning steel and stainless steel. Shape D, a diamond with a 55° corner angle, facilitates copy turning and access to the workpiece profile without tool holder interference. The positive 7° clearance angle (letter C) provides positive geometry with low cutting forces, beneficial for slender and thin-walled components. The insert cuts on one side and provides two cutting edges at its two 55° corners. The small nose radius rε of 0.2 mm provides a very smooth surface finish at low feed rates.

Key advantages of the H6310 cemented carbide insert

  • Two cutting edges — 2 corners of 55° each on one side; the positive geometry prevents use of the other side of the insert.
  • Grade H6310 for ISO groups P and M — PVD-coated carbide: steel (P20-P40) and stainless steel (M20-M40), occasionally also cast iron.
  • Corner radius rε 0.2 mm — finishing and precision machining, very smooth surface finish at low feed rates.
  • The positive 7° clearance angle reduces cutting forces — less deflection of slender and thin-walled workpieces.
  • Dimensions according to ISO 1832: edge length 11.6 mm, IC 9.525 mm (3/8″), thickness 3.97 mm — fit holders with a 11 pocket.
  • The 55° corner angle facilitates copy turning and machining curved profiles without undercutting the walls.

Design and cutting data selection for the DCMT diamond-shaped insert

Positive geometry means that the rake face is inclined and chips flow freely with lower cutting resistance. This design reduces power consumption and temperature in the cutting zone, resulting in a cleaner machined surface. Tolerance class M provides repeatable corner positioning relative to the mounting hole, so the workpiece dimension remains stable after indexing the edge. The countersunk hole accommodates the mounting screw head, keeping the insert from projecting above the tool holder surface. The chip breaker formed on one side controls the flow and breaking of the small chips typical of finishing.

The DCMT 11T302 insert (also written without spaces as dcmt11t302) is suitable for finishing shafts, bushings, and flanges made of structural steels, as well as stainless steel components. Calculate spindle speed using the formula n = 1000·Vc/(π·D): for a workpiece with a diameter of 30 mm at Vc = 200 m/min, the result is approximately 2122 rpm. For stainless steels, maintain a cutting speed of 124–216 m/min and a constant feed rate to limit work hardening of the layer being cut. For roughing and greater depths of cut, choose a version with a larger nose radius that better withstands edge loading. These grade H6310 turning tool inserts are supplied by the Korean brand Horn.

Application limitation

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

Frequently asked questions about the DCMT 11T302 insert

use, turning tool selection, and turning parameters

Two — the diamond has 2 corners of 55° on one side, and the positive geometry (7° clearance angle) allows only one side of the insert to be used. When one edge becomes dull, rotate the insert in the pocket to the other corner without changing the tool holder.

Holders with a 11 diamond-shaped pocket (IC 9.525 mm): for external turning SDHCR/L, SDJCR/L and SDNCN with shank cross sections from 12×12 to 32×32 mm; for internal turning, boring bars S16P–S40U with the suffixes SDXCR/L, SDPCR/L, SDQCR/L, SDUCR/L, or SD-CR/L.

Only in corner radius: 0.2 mm is a finishing version for low feed rates and a very smooth surface finish, 0.4 mm is a general-purpose version, while 0.8 mm better withstands higher feed rates and greater depths of cut. The other dimensions (IC 9.525 mm, thickness 3.97 mm) are identical.

Yes — grade H6310 covers group ISO M20-M40. Maintain a cutting speed of 124–216 m/min, a constant feed, and continuous emulsion cooling: austenitic steel conducts heat poorly and work-hardens when cutting is too slow.
