Chipbreaker Profile
The SGS63903 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 (10°) — balances cutting edge strength with shear efficiency for general purpose 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) | 120 | 0.068 | 11,936 |
| Alloy Steel (≤ 350 HB) | 108 | 0.061 | 10,742 |
| Stainless Steel (304/316) | 84.0 | 0.054 | 8,355 |
| Gray Cast Iron (≤ 250 HB) | 108.0 | 0.075 | 10,742 |
| Aluminum Alloy (≤ 100 HB) | 300 | 0.102 | 29,841 |
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%.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck (HSK-A63) | ✓ Compatible | Best for 3,2 mm; runout ≤ 3 μm |
| Shrink Fit Holder | ✓ Compatible | Excellent gripping force; ideal for high-speed |
| Collet Chuck (ER25/ER32) | ✓ Compatible | Ensure correct collet size; torque to spec |
| Milling Chuck | ✓ Compatible | Suitable for stable drilling; check TIR |
| Weldon Side-Lock | △ Conditional | Acceptable for lower speeds; avoid for 3,2 mm at >96 m/min |
