Chipbreaker Profile
The SGS54707 features an advanced flute profile optimized for alloy steel machining. The 3-flute 3×D design provides superior chip evacuation compared to standard 2-flute drills, reducing the risk of chip packing and hole distortion in medium-depth applications. The polished flute surface minimizes built-up edge (BUE) and ensures smooth chip flow even at elevated feed rates. The specialized land width and margin design enhance drill stability and hole straightness, particularly in deep-hole applications up to 3×D.
| Feature | Description |
|---|---|
| Flute Count | 3 (Triple-flute for stability) |
| Flute Surface | Polished to Ra 0.2 μm |
| Chipbreaker Style | Continuous helical flute with optimized gash |
| Max Drilling Depth | 3×D (standard), 5×D (with peck cycle) |
Recommended Applications & Workpiece Materials
- Primary: Precious Metals
- Material Compatibility: Alloy Steel
- Hardness Range: Up to 48 HRC
- Ideal Industries: Aerospace, Automotive, Medical, Mold & Die, General Engineering
- Hole Types: Through-holes, blind holes, interrupted cuts
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | ★★★★★ | Excellent chip evacuation |
| Blind-hole Drilling | ★★★★☆ | Use reduced feed near bottom |
| Peck Drilling | ★★★★★ | Recommended for depths >2×D |
| Helical Interpolation | ★★★☆☆ | Possible with reduced parameters |
| Stack Drilling | ★★★★☆ | Ensure proper clamping force |
Recommended Cutting Conditions
| Material Group | Cutting Speed (Vc) m/min | Feed (fn) mm/rev |
|---|---|---|
| Carbon Steel (< 30 HRC) | 52-72 | 0.081-0.223 |
| Alloy Steel (30-40 HRC) | 42-62 | 0.081-0.131 |
| Stainless Steel (Austenitic) | 32-52 | 0.081-0.111 |
| Cast Iron (Gray/Ductile) | 72-125 | 0.101-0.273 |
| Aluminum Alloys | 125-165 | 0.131-0.323 |
Operating Guidelines
- Coolant: High-pressure internal coolant (minimum 70 bar) is strongly recommended for optimal chip evacuation and tool life.
- Run-in: Reduce feed by 20% for the first 5 holes to allow the cutting edge to stabilize.
- Pecking: For holes deeper than 2×D, use a peck depth of 1×D with full retract to clear chips.
- Toolholder: Use hydraulic or shrink-fit holders with TIR ≤ 0.003 mm for best results.
- Spindle Warm-up: Allow 10-15 minutes of spindle warm-up before precision drilling operations.
- Inspection: Check drill point under microscope after every 50 holes for wear land development.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| Hydraulic Chuck | ★★★★★ | Best damping and gripping force |
| Shrink Fit | ★★★★★ | Excellent runout control |
| ER Collet (ER16/ER20) | ★★★★☆ | Use high-precision collets (≤5μm) |
| Milling Chuck | ★★★☆☆ | Acceptable for roughing only |
| Weldon Shank | ★★☆☆☆ | Not recommended for precision work |
