Product Overview
The Kyocera SGS32841 is a premium solid carbide endmill engineered for high-performance milling operations. This 1/2 diameter, 3-flute, corner-radius cutter with a 0.090" (2.286 mm) corner radius features an advanced SGS carbide substrate optimized for exceptional wear resistance and thermal stability. Designed for precision machining of ferrous and non-ferrous materials, it delivers consistent surface finishes and extended tool life in demanding CNC environments. This variant features a Tapered Body (TB) design with a slight back-taper to reduce friction and prevent wall rubbing during pocketing and profiling operations.

Grade Details - Key Grade Characteristics
SGS Carbide Grade: A micro-grain tungsten carbide substrate (average grain size 0.6–0.8 μm) with 12% cobalt binder. This grade offers an optimal balance of hardness (HRA 92.0–92.5) and transverse rupture strength (≥3,800 MPa), making it ideal for high-speed milling of steels, stainless steels, and cast irons.
- Hardness: HRA 92.3 (HV 1,650)
- Co Content: 12% by weight
- Grain Size: 0.6 μm (ultra-fine)
- TRS: 3,850 MPa
- Coating Compatibility: TiAlN, TiSiN ready
Grade Comparison Matrix
| Grade | Hardness (HRA) | Co (%) | Best For |
| SGS | 92.3 | 12 | Steel, SS, General purpose |
| SGF | 93.0 | 10 | Hardened steel >45 HRC |
| SGN | 91.5 | 13 | Tough applications, interrupted cuts |
Chipbreaker Profile
This 3-flute corner-radius endmill features a variable-pitch helix design that acts as a natural chipbreaker, reducing harmonic chatter and improving chip evacuation. The flute geometry includes:
- Primary Rake Face: Positive 18° rake for reduced cutting forces
- Chip Curl Radius: Optimized for short, manageable chip formation
- Flute Depth: Deep-groove design for enhanced chip pocket capacity
- Edge Preparation: Micro-honed T-land (0.002–0.003") for edge stability
Recommended Applications & Workpiece Materials
| Material Group | Examples | Machinability |
| Carbon Steel | 1018, 1045, A36 | ★★★★★ Excellent |
| Alloy Steel | 4140, 4340, 8620 | ★★★★☆ Very Good |
| Stainless Steel | 304, 316, 17-4PH | ★★★★☆ Very Good |
| Cast Iron | Gray CI, Ductile CI | ★★★★★ Excellent |
| Tool Steel | H13, D2, O1 (<40 HRC) | ★★★☆☆ Good |
Application Map by Operation
| Operation | Suitability | Recommended Conditions |
| Slotting | ★★★★☆ | Ae = 1.0 × D1, light radial engagement |
| Profiling / Side Milling | ★★★★★ | Ae = 0.2–0.5 × D1, high feed |
| Pocketing | ★★★★☆ | Constant engagement toolpath recommended |
| Plunging | ★★☆☆☆ | Not recommended for vertical plunge; ramp entry only |
| High-Feed Milling | ★★★★☆ | Use with reduced Ae, increased fz |
Recommended Cutting Conditions
| Workpiece Material | Vc (SFM) | fz (IPT) | Ap (Axial) | Ae (Radial) |
| Mild Steel (1018) | 400–600 | 0.002–0.004 | 1.0–1.5 × D1 | 0.2–0.5 × D1 |
| Alloy Steel (4140) | 300–450 | 0.002–0.003 | 1.0 × D1 | 0.2–0.4 × D1 |
| Stainless Steel (304) | 250–350 | 0.0015–0.0025 | 1.0 × D1 | 0.15–0.3 × D1 |
| Gray Cast Iron | 350–500 | 0.003–0.005 | 1.0–2.0 × D1 | 0.3–0.6 × D1 |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece fixturing.
Operating Guidelines
- Coolant: Flood coolant or high-pressure through-spindle (MQL acceptable with reduced speeds)
- Runout: Maintain TIR < 0.0005" (0.013 mm) at the tool tip for optimal life
- Entry Method: Use helical or ramp entry; avoid direct vertical plunging
- Chip Evacuation: Ensure adequate coolant flow to prevent chip re-cutting, especially in deep pockets
- Speed Ramp: Reduce cutting speed by 15% for full-width slotting (Ae = 1.0 × D1)
- Tool Life Benchmark: 45–90 minutes in continuous cut mild steel at recommended parameters
Toolholder Compatibility
| Holder Type | Shank Fit | Max RPM | Remarks |
| ER Collet (ER16/ER20/ER32) | h6 clearance | 20,000 | Most common; ensure collet bore matches shank |
| Hydraulic Chuck | H6 interference | 25,000 | Best for high-speed finishing |
| Shrink Fit | H5 interference | 30,000+ | Maximum rigidity and runout control |
| Milling Chuck (Power Grip) | h6 clearance | 15,000 | Heavy roughing applications |
