Product Overview

The CPMH080208HQ is a premium CVD-coated carbide indexable insert from Kyocera, engineered for precision CNC turning operations. Featuring the advanced CA125P grade with a multi-layer TiCN/Al₂O₃/TiN coating, this insert delivers exceptional wear resistance, fracture toughness, and thermal stability in steel machining environments. The 80° rhombic (diamond) geometry with a 0.8 mm nose radius ensures optimal edge strength and surface finish quality, making it ideal for high-precision finishing, light semi-finishing applications.

ISO Designation Breakdown

Complete decoder for the CPMH080208HQ ISO 1832 designation:

PositionCodeMeaning
1 – ShapeC80° Rhombic (Diamond)
2 – ClearanceP11° (Positive)
3 – ToleranceM±0.13mm (Standard)
4 – TypeHWith cylindrical hole
5 – Length089.525 mm cutting edge
6 – Thickness022.38 mm insert thickness
7 – Radius080.8 mm nose radius
8 – ChipbreakerHQHigh Precision – optimized for finishing & semi-finishing

Engineering Dimensions & Geometry

Verified dimensional data per ISO 1832:2012 standard:

ParameterValueNotes
Inscribed Circle (IC)9.525 mmNominal cutting edge length per ISO 1832
Insert Thickness (S)2.38 mm±0.13 mm tolerance class M
Nose Radius (rε)0.8 mmDirectly affects surface roughness Rz
Corner Angle80°Determines tool engagement & stability
Relief AnglePositiveReduces flank rubbing, lowers heat
Hole Diameter4.4 mm (standard clamp)Compatible with lever-lock toolholders

Surface roughness estimate: Rz ≈ f² / (8 × rε) × 1000. For f = 0.1 mm/rev and rε = 0.8 mm, theoretical Rz ≈ 1.56 μm.

Grade Details – Key Grade Characteristics

  • Substrate: Newly developed high-temperature-strength carbide with enhanced plastic-deformation resistance
  • Coating Stack: Proprietary TiCN base layer + ultra-uniform Al₂O₃ (alumina) crystal layer + gold TiN surface layer
  • Rake Face: Black finish – highly uniform alumina reduces crater wear and suppresses chip welding
  • Flank Face: Gold finish – hard surface layer improves abrasion resistance; color contrast aids edge-wear inspection
  • ISO Application Group: P15–P35 (steel machining, continuous to interrupted)
  • Hardness: ~1,600 HV (coating surface); substrate optimized for 800–1,000°C cutting zone

Grade Comparison Matrix

CA115PTiCN + Al₂O₃ + TiN (CVD)Steel, high-speedContinuous → light interrupted
CA525TiCN + Al₂O₃ + TiNSteel, stainlessGeneral purpose
CA6515TiCN + Al₂O₃ + TiNSteel, heavy dutyHeavy interrupted

Chipbreaker Profile

HQ – High Precision – optimized for finishing & semi-finishing

  • Geometry: High-positive rake with polished groove for minimal adhesion
  • Chip Formation: Fine, needle-like chips, excellent surface integrity
  • Cutting Force: Low-to-moderate radial & axial forces; reduced chatter risk on slender workpieces
  • Coolant Compatibility: Optimized for wet cutting and MQL; flood coolant recommended for deep cuts

Recommended Applications & Workpiece Materials

  • Primary Materials: Hardened steel, alloy steel, stainless steel
  • Hardness Range: 80–350 HB (ideal 150–280 HB)
  • Typical Components: Shafts, gears, bearing races, hydraulic cylinders, valves, pump housings
  • Industries: Automotive, aerospace, general machinery, energy, mold & die

Application Map by Operation

OperationSuitabilityNotes
External Turning★★★★★ ExcellentPrimary application; stable at high speeds
Internal Boring★★★★☆ Very GoodUse with minimum 11.525 mm bore diameter

Profiling / Copying★★★☆☆ Good80° corner provides strong edge entry
Interrupted Cutting★★★☆☆ GoodReduce Vc 20% for heavy interrupted cuts

Recommended Cutting Conditions

Starting parameters for CA125P with CPMH080208HQ in wet machining of carbon/alloy steel:

OperationVc (m/min)f (mm/rev)ap (mm)Condition
Finishing3000.050.1Wet / MQL
Semi-Finishing2000.075000000000000010.2Wet
Medium2000.12 mm/rev0.8 mmWet

Adjustments: Reduce Vc by 15% for dry cutting; increase feed by 10% for cast iron; reduce both by 20% for stainless steel.

Operating Guidelines

  • Run-in Period: For first 5 min, reduce Vc by 25% to stabilize coating and edge micro-geometry
  • Tool Life Indicator: Monitor flank wear (VB) ≤ 0.3 mm; replace insert when gold flank shows uniform wear land
  • Chip Inspection: Blue or purple chip color indicates excessive heat – reduce Vc or increase coolant flow
  • Clamping Torque: Lever-lock toolholders: 3.5–4.5 N·m; do not overtighten to avoid insert fracture
  • Storage: Keep inserts in original blister pack; avoid direct sunlight and humidity >60% RH

Toolholder Compatibility

PCLN, PCLNL, MCLN, MCLNR, CCLN (80° rhombic). Use lever-lock or top-clamp styles. Recommended shim: 80° diamond shim (e.g., ST-1303).
