Product Overview
The Kyocera SGM01122 is a precision-engineered solid carbide 3-flute square endmill with tapered neck, featuring the PR1535 grade with PVD TiAlN coating. This 0.042" diameter tool is optimized for aggressive material removal in slotting, profiling, and roughing operations while maintaining excellent surface finish quality and dimensional stability.
The tapered neck design provides enhanced reach and accessibility in deep cavity machining, while the 3-flute configuration offers an optimal balance between chip evacuation and core strength. Engineered for general milling, slotting, profiling, roughing, this endmill delivers extended tool life and reduced cycle times across a broad spectrum of workpiece materials.

Chipbreaker Profile
The SGM 3-flute square series features an advanced chipbreaker geometry optimized for high-efficiency milling:
- Variable Helix Design (38°): Suppresses regenerative vibration and extends tool life in unstable setups
- Positive Rake Face: Reduces cutting forces by 15% compared to conventional geometries, minimizing deflection in long-reach applications
- Polished Flute Surface: Mirror-finish flutes prevent chip adhesion and built-up edge, critical for stainless steel machining
- Core Thickness Optimization: 35% core ratio provides maximum rigidity for the tapered neck while maintaining chip evacuation
- Sharp Cutting Edge: Honing preparation ensures clean shearing action and reduced burr formation

Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Slotting (Full Diameter) | ★★★★★ Excellent | Up to 1.5xD depth; 3-flute optimizes chip evacuation |
| Side Milling / Profiling | ★★★★★ Excellent | High radial engagement capability with stable finish |
| Pocketing (Trochoidal) | ★★★★★ Excellent | Tapered neck ideal for deep pocket access |
| Roughing | ★★★★☆ Good | High feed rates possible; adjust ae for stability |
| High-Speed Machining (HSM) | ★★★★☆ Good | Variable helix suppresses chatter at high speeds |
| Deep Cavity Machining | ★★★★★ Excellent | Tapered neck provides extended reach without interference |
Recommended Cutting Conditions
| Material | Vc (m/min) | fz (mm/tooth) | ap max (mm) | ae max (mm) |
|---|---|---|---|---|
| Carbon Steel (C45) | 90 | 0.004 | 1.067 | 0.853 |
| Stainless Steel (304) | 70 | 0.003 | 0.800 | 0.640 |
| Cast Iron (GG25) | 110 | 0.005 | 1.333 | 1.067 |
| Aluminum (6061-T6) | 180 | 0.008 | 1.600 | 1.280 |
Note: Values are starting recommendations for stable setups. Reduce parameters by 20-30% for long-overhang or deep-cavity applications. Use high-pressure coolant for stainless steel and titanium alloys. Always verify spindle speed and feed rate against machine capabilities.
Operating Guidelines
- Tool Runout: Maintain TIR ≤ 0.005 mm at the tool tip for optimal tool life and surface finish
- Coolant Strategy: Flood coolant or through-spindle coolant (TSC) recommended; for aluminum, consider air blast or MQL to prevent chip re-cutting
- Entry Strategy: Use helical or ramping entry at 2-3° angle; avoid direct plunging with square endmills
- Radial Engagement: For roughing, ae = 0.6-0.8 × D1; for finishing, ae = 0.1-0.2 × D1
- Axial Depth: For slotting, ap ≤ 1.0 × D1; for profiling, ap ≤ 1.5 × D1 with reduced ae
- Chip Evacuation: Ensure adequate coolant pressure (≥70 bar for TSC) to clear chips from deep cavities
- Tool Inspection: Check for coating wear, edge chipping, and neck deflection after extended use
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chucks | ✓ Recommended | Best damping for long-reach tools; TIR < 0.003 mm |
| Shrink Fit Holders | ✓ Recommended | Excellent rigidity and concentricity for high-speed operations |
| ER Collet Systems (ER16/ER20) | ✓ Compatible | Use precision collets (AA grade); minimize protrusion |
| Milling Chucks | ✓ Compatible | Suitable for general milling; ensure proper torque |
| Side-Lock Endmill Holders | △ Not Recommended | May cause runout issues; avoid for precision work |
