Product Overview
The Kyocera SGS 3/4 SGS30806 is a solid-carbide 3-flute, square-end end mill with TC (TiCN) coating. The 3/4″ (19.05 mm) cutting diameter on a rigid 3/4" shank is built for slotting, profiling and pocketing in steels and cast metals.
The 3-flute layout opens deep chip gullets and suppresses harmonic chatter, while the TiCN (Titanium Carbonitride) coating — harder and more abrasion-resistant than TiN — protects the cutting edges against wear in steels, stainless alloys and cast iron.

Chipbreaker Profile
Chip control on this 3-flute tool comes from its flute and gash geometry:
- Extra-deep polished gullets — fewer flutes means more room per flute, so chips clear before they pack.
- 30° helix lifts chips smoothly out of the cut with low cutting forces.
- Odd (3) flute count breaks up harmonic vibration for chatter-free finishes.
- Center-cutting gash allows plunging and ramping entries without a pilot hole.
Recommended Applications & Workpiece Materials
| Workpiece Material (ISO Class) | Suitability | Notes |
|---|---|---|
| ISO P — Carbon & alloy steels (≤35 HRC) | Excellent | Primary application |
| ISO M — Stainless steels (303/304/316) | Very Good | Light radial engagement, steady feed |
| ISO K — Cast irons | Excellent | Abrasion-resistant TiCN excels here |
| Copper Alloys (brass, bronze) | Good | Light cuts, air blast |
| ISO N — Aluminum (wrought) | Not recommended | Aluminum affinity — use uncoated variant |
| ISO H — Hardened steels (>45 HRC) | Not recommended | Use TiAlN-coated variant |
Application Map by Operation
| Milling Operation | Suitability | Guideline |
|---|---|---|
| Full Slotting | ★★★★☆ | Axial DOC ≤ 0.5×D (0.375"), reduce feed 20% |
| Side Milling / Profiling | ★★★★★ | Radial WOC 5–15% of D for best finish |
| Pocketing | ★★★★☆ | Ramping entry at 3–5° |
| Thin-Wall Milling | ★★★★★ | Odd flute count minimizes chatter marks |
| Plunging | ★★★☆☆ | Center-cutting; peck in 0.5×D steps |
| 3D Contouring | ★★★☆☆ | Square end — use ball nose variant for 3D work |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed | Spindle Speed | Feed per Tooth | Feed Rate (3FL) |
|---|---|---|---|---|
| Mild / Low-Carbon Steel | 120 SFM | 600 RPM | 0.0045"/tooth | 8.1 IPM |
| Alloy Steel (≤35 HRC) | 100 SFM | 500 RPM | 0.0045"/tooth | 6.7 IPM |
| Stainless Steel (304/316) | 85 SFM | 400 RPM | 0.0045"/tooth | 5.4 IPM |
| Cast Iron | 140 SFM | 700 RPM | 0.0045"/tooth | 9.4 IPM |
| Brass / Bronze | 220 SFM | 1,100 RPM | 0.0045"/tooth | 14.8 IPM |
Starting recommendations for rigid setups; adjust ±20% for machine stiffness and holder runout.
Operating Guidelines
- Keep tool-holder runout below 0.0004" (10 µm) TIR — runout is the leading cause of premature edge failure.
- Use the shortest possible gauge length for maximum rigidity.
- TiCN prefers moderate temperatures — use flood coolant or MQL in steels; avoid dry high-heat cuts.
- Do not use on aluminum — switch to the uncoated 305xx variant to prevent edge welding.
- Climb mill whenever machine rigidity allows for better finish and tool life.
- Start at 70% of recommended feed and speed, then optimize upward in 10% steps.
- Retire the tool at the first sign of edge chipping or size drift.
Toolholder Compatibility
| Holder System | Specification | Notes |
|---|---|---|
| ER Collet Chuck | ER16 / ER20 collet, 3/4" bore | Best all-round choice |
| Shrink-Fit Holder | 3/4" bore | ≤3 µm runout for finishing |
| Side-Lock (Weldon) End Mill Holder | 3/4" bore | Maximum grip for slotting |
| Hydraulic Chuck | 3/4" bore | Excellent vibration damping |
| Spindle Interface | BT40, CAT40, HSK-A63 or straight-shank adapters | Match to machine spindle |
