Chipbreaker Profile
The SGM series features a polished, precision-ground flute geometry optimized for micro-scale chip evacuation:
- Flute Profile: Parabolic or standard helix with polished surfaces to minimize chip adhesion
- Chipbreaker Type: Natural chip curling via optimized rake angle (typically 8°–12° positive)
- Chip Evacuation: Through-flute air/oil mist recommended for deep holes >3×D
- Surface Treatment: Edge honing (T-land) of 0.02–0.05 mm to prevent micro-chipping
Recommended Applications & Workpiece Materials
| Material Group | Examples | Machinability | Notes |
|---|---|---|---|
| Carbon & Alloy Steels | 1045, 4140, 4340 | ★★★★★ Excellent | Ideal for <30 HRC; reduce speed >35 HRC |
| Stainless Steels | 303, 304, 316, 17-4PH | ★★★★☆ Very Good | Use peck cycle; avoid work hardening |
| Tool & Die Steels | D2, A2, H13 | ★★★☆☆ Good | Pre-heat treatment drilling preferred |
| Non-Ferrous Metals | Aluminum 6061, Brass 360 | ★★★★★ Excellent | High speeds possible; excellent finish |
| Plastics & Composites | PEEK, G10, FR4 | ★★★★☆ Very Good | Use sharp edge; avoid heat buildup |
Application Map by Operation
| Operation Type | Suitability | Recommended Peck Depth |
|---|---|---|
| Blind Hole Drilling | ✓ Recommended | 1×D per peck |
| Through Hole Drilling | ✓ Recommended | 1×D to 2×D per peck |
| Deep Hole Drilling (>3×D) | △ Caution | 0.5×D per peck; forced coolant |
| Micro-Drilling (<1 mm) | ✓ Recommended | 0.3×D per peck; high RPM |
| Enlarging / Reaming | ✗ Not Recommended | — Use dedicated reamer |
Recommended Cutting Conditions
| Material | Cutting Speed (Vc) | Feed per Rev (fn) | RPM (approx.) |
|---|---|---|---|
| Mild Steel (C < 0.3%) | 40 – 60 m/min | 0.01 – 0.03 mm/rev | 8,000 – 25,000 |
| Alloy Steel (30-40 HRC) | 25 – 40 m/min | 0.008 – 0.02 mm/rev | 5,000 – 16,000 |
| Stainless Steel (Austenitic) | 15 – 25 m/min | 0.005 – 0.015 mm/rev | 3,000 – 10,000 |
| Aluminum Alloys | 80 – 120 m/min | 0.02 – 0.05 mm/rev | 15,000 – 50,000 |
| Copper / Brass | 60 – 100 m/min | 0.015 – 0.04 mm/rev | 12,000 – 40,000 |
| Plastics / Composites | 50 – 80 m/min | 0.02 – 0.06 mm/rev | 10,000 – 30,000 |
Note: RPM values are approximate for common diameters. Actual RPM = (Vc × 1000) / (π × D). Reduce speeds by 20-30% for deep holes or interrupted cuts.
Operating Guidelines
- Runout: Maintain TIR < 0.01 mm at the tool tip. Excessive runout causes uneven wear and breakage.
- Coolant: High-pressure coolant (70+ bar) or MQL (Minimum Quantity Lubrication) strongly recommended for holes >2×D.
- Peck Cycle: Always use peck drilling for depths >1.5×D. Full retraction is not required; use "chip breaking" peck with 0.5×D retract.
- Entry Angle: Use chamfered or center-drilled entry when possible. Avoid direct entry on curved surfaces without spot drilling.
- Tool Life Monitoring: Replace tool when flank wear exceeds 0.05 mm or when burr formation increases significantly.
- Spindle Warm-Up: Warm up spindle for 10-15 minutes before precision micro-drilling to ensure thermal stability.
Toolholder Compatibility
| Holder Type | Compatibility | Best Use Case |
|---|---|---|
| Collet Chuck (ER11 / ER16) | ✓ High | General purpose; good grip and runout |
| Hydraulic Chuck | ✓ Excellent | Best for high-speed micro-drilling |
| Shrink Fit Holder | ✓ Excellent | Maximum rigidity and runout control |
| Drill Chuck (Keyed/Keyless) | △ Moderate | Acceptable for low-speed applications only |
