Chipbreaker Profile
The SGS63949 features an optimized chipbreaker geometry specifically engineered for 5XD drilling operations. The flute profile incorporates a variable helix design that minimizes harmonic vibration while promoting efficient chip curl and breakage.
- Wide-flute design — increases chip pocket volume for deeper hole drilling without chip packing
- Polished flute surface (Ra 0.2 μm) — reduces friction and built-up edge formation
- Variable core thickness — strengthens the drill center while maintaining flexibility at the periphery
- Optimized rake angle (8°) — balances cutting edge strength with shear efficiency for carbon steel

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Primary application; optimized for continuous cut exit |
| Blind-Hole Drilling | ★★★★☆ | Reduce feed by 20% in last 2×D to avoid bottom damage |
| Spot Drilling | ★★★★☆ | 140° point angle matches standard countersinks |
| Chamfering | ★★★☆☆ | Possible with reduced depth; not primary purpose |
| Enlarging / Reaming | ★★☆☆☆ | Not recommended; use dedicated reamer for tolerance |
| Peck Drilling | ★★★★★ | Recommended for depths >5×D; 1×D peck increment |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Approx. RPM |
|---|---|---|---|
| Carbon Steel (≤ 300 HB) | 130 | 0.109 | 5,046 |
| Alloy Steel (≤ 350 HB) | 117 | 0.098 | 4,541 |
| Stainless Steel (304/316) | 91.0 | 0.087 | 3,532 |
| Gray Cast Iron (≤ 250 HB) | 117.0 | 0.120 | 4,541 |
| Aluminum Alloy (≤ 100 HB) | 325 | 0.164 | 12,615 |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant concentration, and workpiece fixturing. Reduce Vc by 15% for peck drilling cycles.
Operating Guidelines
- Coolant: Use high-pressure internal coolant (≥ 70 bar) for holes deeper than 2×D. Minimum 5% water-miscible coolant concentration.
- Run-in: For the first 5 holes, reduce Vc by 20% and feed by 10% to season the cutting edge.
- Pecking: For 5XD drills, use full retraction pecking at 1×D increments when drilling beyond 5×D depth.
- Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent walk and chipping.
- Exit Strategy: Reduce feed by 50% in the last 1 mm of through-holes to prevent burr and breakout.
- Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB exceeds 0.15 mm or when burr formation increases.
- Speed/Feed Adjustment: If chip color is blue/purple, reduce Vc by 10%. If chips are silver/white, increase feed by 5%.
