Turning Inserts

1) Negative Turning Inserts

Negative Turning Inserts are engineered for high-strength, high-performance metal cutting operations. Built with a 0° clearance angle, these inserts deliver exceptional edge stability, multi-edge usability, and enhanced tool life. Their robust geometry allows them to withstand heavy cutting loads, making them ideal for machining tough materials such as alloy steels, stainless steels, cast iron, and super alloys.

Whether for roughing or continuous high-feed operations, Negative Turning Inserts ensure dependable precision and durability.

Key Features:

  • Superior Edge Strength: The negative rake design offers outstanding rigidity, reducing the chance of chipping during tough cuts.
  • Multiple Cutting Edges: Each insert can be indexed several times, lowering tooling costs and improving productivity.
  • Optimized for Tough Materials: Performs reliably on hardened steels, stainless steels, cast iron, and heat-resistant alloys.
  • Advanced Carbide Grades: Enhanced wear resistance ensures consistent performance, even in demanding machining environments.
  • High-End PVD/CVD Coatings: Improves thermal stability, reduces friction, and extends tool life.
  • Improved Chip Control: Special chip-breaker designs ensure smooth chip flow and better machining stability.
  • Ideal for Roughing & Heavy Loads: Built to handle high feed rates and continuous cutting without losing accuracy.

Example:

CNMG 120408 – Negative Turning Insert

Type: CNMG (80° Diamond)

Size: 12 mm

Application: Roughing & general-purpose turning

Material: Carbide

Coating: CVD coated for high wear resistance

Features:

  • Multi-edge usability (4 edges)
  • Ideal for steel and stainless steel
  • Excellent chip breaking at medium to high feeds
  • Suitable for both continuous and interrupted cuts

2) Positive Turning Inserts

Positive Turning Inserts are designed for light to medium machining, offering exceptional sharpness, smooth cutting action, and reduced cutting forces. With a positive rake angle and thinner cross-section, these inserts produce cleaner finishes and are ideal for machining small parts, delicate components, and materials that require low cutting resistance — such as aluminum, stainless steel, mild steel, and non-ferrous metals.

Their razor-sharp edges ensure precise, vibration-free cutting, making them perfect for finishing and semi-finishing operations where accuracy and surface quality matter most.

Key Features:

  • Low Cutting Forces: Positive rake geometry enables smooth, effortless cutting, ideal for weaker or delicate workpieces.
  • Sharp Cutting Edges: Provides excellent surface finish with reduced burr formation and minimal heat generation.
  • Ideal for Small & Lightweight Machines: Requires less spindle power, making it suitable for compact CNCs and light turning setups.
  • Excellent for Finishing Operations: Offers high precision, stable cutting, and better surface quality on finishing passes.
  • Optimized for Soft & Medium Materials: Performs exceptionally on aluminum, mild steel, stainless steel, copper, and other non-ferrous metals.
  • Improved Chip Evacuation: Positive geometry naturally lifts and curls chips away from the workpiece, preventing chip packing.
  • Premium Carbide & PVD Coatings: Ensures edge sharpness while providing wear resistance and thermal stability during high-speed cutting.

Example: 

CCMT 060204 – Positive Turning Insert

Type: CCMT (80° Diamond, positive rake)

Size: 06 mm

Application: Finishing & semi-finishing

Material: Ultra-fine carbide

Coating: PVD coated for sharpness & wear resistance

Features:

  • Designed for low cutting forces
  • Best suited for small parts & precision turning
  • Excellent for stainless steel, mild steel & aluminum
  • Produces fine surface finish with minimal vibration
  • Single-sided but extremely sharp cutting edges

3) Turning Pos Aluminium

Turning POS Aluminium Inserts are designed for precision machining of aluminium and other non-ferrous materials where sharpness, speed, and ultra-smooth finishing are essential.

With a highly positive rake angle and razor-sharp cutting edges, these inserts deliver extremely low cutting resistance, eliminate built-up edge (BUE), and ensure bright, mirror-quality surface finishes.

Ideal for aerospace aluminium components, automotive parts, mould machining, and general aluminium turning, POS Aluminium Inserts offer consistent performance at high RPMs while maintaining exceptional edge integrity.

Key Features:

    • Ultra-Positive Geometry: Provides low cutting forces and smooth, effortless machining—perfect for lightweight aluminium components.
    • Razor-Sharp Cutting Edge: Prevents built-up edge and ensures clean, burr-free cutting at high speeds.
  • Polished Rake Face: Minimizes friction and improves chip evacuation for long, continuous aluminium chips.
  • Optimized for Non-Ferrous Materials: Perfect for aluminium alloys, copper, brass, magnesium, and plastics.
  • High-Speed Machining Ready: Engineered to perform at very high spindle speeds typical in aluminium turning.
  • Premium Polished or Uncoated Carbide: Ensures maximum sharpness and prevents material sticking, improving life and finish.
  • Superior Surface Finish: Produces glossy, reflective finishes ideal for precision parts and moulds.

Example: 

VCGT 110302 – POS Aluminium Insert

Type: VCGT (35° diamond, high-positive geometry)

Size: 11 mm

Application: High-speed finishing of aluminium

Material: Ultra-fine, polished carbide

Coating: Uncoated or PVD-polished grade

Features:

  • Exceptional sharpness for high-precision aluminium machining
  • Prevents built-up edge during long cuts
  • Suitable for thin, delicate components
  • Produces mirror-like surface finishes
  • Ideal for aerospace and automotive aluminium alloys

4) Parting & Grooving

Parting & Grooving Inserts are specially designed for precise cutting, slotting, and separation operations in turning applications. Engineered for stability and accuracy, these inserts ensure clean groove formation, controlled chip flow, and minimal material waste.

With optimized geometries and high-strength carbide grades, they deliver excellent performance in both shallow and deep grooving, as well as reliable part-off operations across a wide range of materials.

Used extensively in automotive, aerospace, and general manufacturing, Parting & Grooving Inserts provide consistent results even under demanding cutting conditions.

Key Features:

  • High Stability Design: Rigid insert geometry minimizes vibration during deep grooving and parting operations.
  • Clean & Accurate Groove Formation: Ensures precise groove widths with excellent dimensional control.
  • Optimized Chip Control: Special chip-breaker designs prevent chip jamming and improve process reliability.
  • Strong Carbide Substrate: Withstands high cutting forces and resists edge chipping during interrupted cuts.
  • High-Performance Coatings: PVD/CVD coatings enhance wear resistance and thermal stability.
  • Suitable for Multiple Materials: Ideal for steel, stainless steel, cast iron, and non-ferrous materials.
  • Efficient Material Separation: Delivers smooth, burr-free parting with minimal tool wear.
