Kyocera 0.0200 Solid Carbide SGM01585 ENDMILL 3FL BN - CNC Milling

Product Overview

The Kyocera 0.0200 ENDMILL 3FL BN SGM01585 is a premium solid carbide ball-nose endmill engineered for high-performance CNC milling operations. With a 0.0200" cutting diameter and 3FL design, this tool delivers exceptional surface finish, dimensional accuracy, and extended tool life across a wide range of workpiece materials. The nACo coating minimizes friction and enhances heat resistance, making it ideal for high-speed machining environments in aerospace, automotive, die/mold, and general manufacturing sectors.

• Transverse Rupture Strength (TRS): ≥ 4,200 MPa
• Coating: nACo multi-layer PVD coating (2.5–3.5 μm thickness)
• Coating Hardness: 3,300 HV
• Oxidation Temperature: 1,100°C (nACo variant)
• Coefficient of Friction: 0.35 (dry machining)
• Surface Finish (Ra): 0.05 μm on coating surface

Grade Comparison Matrix

Chipbreaker Profile

Although the SGM01585 is a solid endmill (not an indexable insert), its flute geometry incorporates an advanced chipbreaker design:

• Flute Profile: Variable helix with unequal flute spacing to suppress chatter and harmonics
• Core Diameter: 60% of tool diameter for optimal rigidity in deep-pocket milling
• Rake Angle: Positive 8° radial rake, 5° axial rake for efficient chip flow
• Chipbreaker Geometry: Concave flute form with polished chip evacuation channels for smooth surface generation in complex geometries
• Edge Preparation: Micro-honed cutting edge (0.02 mm hone radius) for edge stability
• Chip Evacuation: Optimized for upward spiral chip flow; suitable for both dry and MQL machining

Recommended Cutting Conditions

Values below are starting parameters for Steel (P). Adjust based on machine rigidity, coolant delivery, and workpiece fixturing.

Operating Guidelines

• Runout: Maintain TIR ≤ 0.01 mm (0.0004") at the tool tip to prevent uneven wear and chatter.
• Coolant: Flood coolant or air blast recommended for steel and stainless; compressed air preferred for aluminum to prevent built-up edge.
• Entry Strategy: Use helical or ramp entry; avoid direct plunging with non-center-cutting tools.
• Stepover: For finishing, keep radial stepover (ae) between 5–10% of tool diameter to achieve mirror surface finish.
• Tool Overhang: Minimize overhang to 4×D or less. Use shrink-fit or hydraulic chucks for best results.
• Pre-Machining Inspection: Verify collet condition and spindle bearing health before high-speed operation.
• Tool Life Monitoring: Replace tool when flank wear (VB) reaches 0.15 mm or when surface finish degrades below Ra 0.4 μm.
