Kyocera 1/2 ENDMILL 5FL 0.010R TM IC SGS38836

Product Overview

The Kyocera 1/2 ENDMILL 5FL 0.010R TM IC SGS38836 is a high-performance solid carbide endmill engineered for precision milling operations in modern CNC machining centers. With a 1/2 inch (12.7 mm) cutter diameter, five flutes, and a fine 0.010 inch (0.254 mm) corner radius, this tool combines an ultra-fine carbide substrate with an advanced TM multi-layer PVD coating to deliver exceptional wear resistance, thermal stability, and surface finish quality. The IC grade geometry minimizes cutting forces, reduces vibration, and optimizes chip evacuation across finishing and semi-finishing tasks, making it ideal for demanding production environments where accuracy and repeatability are critical.

Designed for aerospace, automotive, die/mold, and general engineering applications, the SGS38836 endmill offers stable performance across a wide range of ferrous and non-ferrous materials. Its variable-pitch flute design and polished flutes help reduce built-up edge and improve chip flow, enabling extended tool life and predictable machining economics.

Engineering Dimensions & Geometry

Grade Details - Key Grade Characteristics

The IC grade combines an ultra-fine-grained tungsten carbide substrate with the proprietary TM PVD coating to provide an outstanding balance of hardness, toughness, and thermal stability. The sub-micron grain structure improves edge sharpness and coating adhesion, while the multi-layer coating reduces heat transfer into the substrate and suppresses crater wear in high-speed machining.

Chipbreaker Profile

The flute and edge geometry of the SGS38836 is tuned to break chips efficiently at the cutting edge while minimizing force spikes. The 0.010 inch corner radius improves edge strength and creates a smooth machined transition, while the variable helix and pitch suppress chatter during high-speed finishing.

• 35° Helix Angle: Provides smooth axial cutting action and excellent surface finish.
• Variable Flute Pitch: Breaks up harmonic vibration to reduce chatter and extend tool life.
• Eccentric Relief: Reduces rubbing on the flank and lowers heat generation.
• 0.010" Corner Radius: Reinforces corner edges and improves part edge quality.
• Polished Flute Surface: Enhances chip evacuation and reduces built-up edge.

Recommended Applications & Workpiece Materials

*For aluminum, use the tool at reduced speeds and with appropriate coolant to avoid chip welding; dedicated aluminum geometries may be preferred for high-volume work.

Recommended Cutting Conditions

Parameters are starting values for stable setups with 3D carbide holders; adjust based on machine rigidity, coolant, and part fixturing.

Operating Guidelines

• Runout: Maintain total indicator runout below 0.005 mm (0.0002 in) at the cutting tip for best surface finish and tool life.
• Peck Cycle: When plunging or slotting, use a ramp or helical entry and a peck cycle to avoid full-width engagement and chip packing.
• Coolant: Apply adequate coolant or air blast to evacuate chips and control temperature, especially in stainless steel and titanium.
• Entry Angle: Use ramp angles ≤ 5° for conventional entry, or employ a helical interpolation path to reduce impact loading.
• Speed / Feed: Start at the lower end of the recommended range for new materials; increase speed only after confirming stable chip formation and part quality.
• Tool Life: Monitor flank wear and replace the tool when edge wear reaches 0.15–0.20 mm to maintain dimensional accuracy and avoid catastrophic failure.
