Chipbreaker Profile
The SGM series features an optimized flute profile engineered for alloy steel applications. The 30° helix angle with polished flute surfaces ensures smooth chip evacuation, reducing built-up edge and minimizing heat retention at the cutting edge. The dual-margin design provides superior hole straightness and surface finish quality.
| Profile Feature | Description |
|---|---|
| Flute Form | Parabolic with polished finish |
| Chipbreaker Type | Continuous helical groove (no discrete breakers) |
| Chip Control | Optimized for short, curled chips in alloy steel |
| Coolant Channel | Through-tool (internal coolant ready) |
Recommended Applications & Workpiece Materials
- Alloy Steel: Ideal for continuous and interrupted cuts in alloy steel with stable chip formation.
- Alloy Steels: Suitable for 4140, 4340, and similar medium-carbon alloys up to 35 HRC.
- Cast Irons: Compatible with gray cast iron (GG25) and nodular iron (GGG40) at optimized speeds.
- Non-Ferrous: Effective in aluminum alloys when used with appropriate coolant strategy.
- General Engineering: Perfect for precision holes in automotive, aerospace, and mold-making sectors.
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Standard application; use peck cycle for depths > 3×D |
| Blind-Hole Drilling | ★★★★☆ Very Good | Ensure adequate coolant flow for chip evacuation |
| Stack Drilling | ★★★☆☆ Good | Use reduced feed to prevent burr between plates |
| Micro-Drilling | ★★★★☆ Very Good | Rigid setup and high-speed spindle recommended |
| Enlarging / Reaming | ★★☆☆☆ Fair | Not recommended; use dedicated reamer for precision |
Recommended Cutting Conditions
| Material Group | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel (< 0.5% C) | 89.8 – 109.8 | 0.09 – 0.13 | Emulsion (8–10%) |
| Alloy Steel (30–45 HRC) | 71.8 – 86.8 | 0.072 – 0.102 | Emulsion or Oil |
| Stainless Steel (Austenitic) | 65.9 – 80.9 | 0.081 – 0.111 | High-pressure coolant |
| Cast Iron (Gray / Nodular) | 107.9 – 132.9 | 0.09 – 0.14 | Compressed air or mist |
| Aluminum Alloy | 224.5 – 274.5 | 0.135 – 0.215 | Mist or flood coolant |
Note: Values are starting recommendations. Adjust based on machine rigidity, workpiece clamping, and coolant delivery efficiency.
Operating Guidelines
- Runout: Maintain spindle runout ≤ 0.01 mm to prevent premature edge chipping and hole oversize.
- Peck Drilling: For holes deeper than 3×D, use a peck cycle with retract to 1×D above the bottom of each peck.
- Coolant Pressure: Minimum 70 bar (1,000 psi) for through-tool coolant; ensures effective chip evacuation in deep holes.
- Entry Angle: Use a 90° entry surface or chamfer to avoid drill walk and ensure concentric start.
- Pre-Spotting: Recommended for 1.97 mm drills; use a 90° or 120° spot drill to create a precise pilot.
- Speed Ramp: Reduce spindle speed by 20% for the first 2 mm of engagement, then ramp to full Vc.
- Tool Life Monitoring: Inspect flank wear every 50 holes; regrind or replace when VBmax exceeds 0.15 mm.
