Recommended Applications & Workpiece Materials
| Material Group | Examples | Suitability | Notes |
|---|---|---|---|
| Carbon Steel | C45, C60, 1045, 1060 | Excellent | Ideal for high-speed drilling |
| Alloy Steel | 42CrMo4, 4140, 4340 | Excellent | Consistent performance up to 45 HRC |
| Tool Steel | H13, D2, O1 (≤40 HRC) | Very Good | Reduce speed by 20% for hardened grades |
| Stainless Steel | 304, 316, 303 | Good | Use peck drilling cycle recommended |
| Cast Iron | GG25, GGG40, Class 40 | Good | Dry machining possible |
| Aluminum | 6061, 7075 | Fair | Polished flutes prevent built-up edge |
Application Map by Operation
| Operation Type | Recommended Use | Max Depth | Key Considerations |
|---|---|---|---|
| Through-Hole Drilling | Primary application | 3×D | Standard peck cycle for depths >2×D |
| Blind-Hole Drilling | Recommended with caution | 2×D | Ensure adequate chip evacuation |
| Spot Drilling | Not recommended | — | Use dedicated spot drill for starting |
| Enlarging | Possible with reduced feed | 1.5×D | Reduce feed by 30% for enlarging |
| Cross-Hole Drilling | Requires reduced parameters | 1×D | Reduce speed by 25% at intersection |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | RPM | Coolant |
|---|---|---|---|---|
| Carbon Steel (<30 HRC) | 82 | 0.110 | 4,774 | Emulsion (8-10%) |
| Alloy Steel (30-40 HRC) | 66 | 0.093 | 3,819 | Emulsion (10-12%) |
| Stainless Steel (304/316) | 62 | 0.087 | 3,559 | Emulsion (10-12%) |
| Cast Iron (GG25) | 102 | 0.130 | 5,903 | Dry or Mist |
| Tool Steel (≤40 HRC) | 54 | 0.083 | 3,103 | Emulsion (12-15%) |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece setup, and desired surface finish. For peck drilling, divide total depth into increments of 1×D to 1.5×D.
Operating Guidelines
- Starting Hole: Always use a spot drill or center drill to create a precise starting point. Recommended spot drill angle: 90°-120°.
- Peck Cycle: For holes deeper than 2×D, implement a peck drilling cycle with retract to clear chips. Peck depth: 1×D to 1.5×D.
- Coolant Pressure: Maintain coolant pressure ≥ 20 bar for through-tool coolant systems to ensure effective chip evacuation.
- Feed Rate: Reduce feed by 50% for the first 1 mm of entry to prevent chipping. Resume full feed once fully engaged.
- Tool Life Monitoring: Monitor flank wear (VB). Resharpen or replace when VB reaches 0.3 mm or when surface finish degrades.
- Storage: Store in original packaging in a dry environment. Avoid contact between cutting edges to prevent chipping.
Toolholder Compatibility
| Holder Type | Compatibility | Recommended Application |
|---|---|---|
| ER Collet Chuck (ER16/ER20) | Fully compatible | General purpose drilling, good runout control |
| Hydraulic Chuck | Excellent | High-precision applications, minimal runout |
| Shrink Fit Holder | Excellent | High-speed machining, best rigidity |
| Drill Chuck (Keyless) | Acceptable for short runs | Manual setups, prototype work |
| Whistle Notch Holder | Not recommended | Insufficient grip for carbide drills |
Runout Requirement: Maximum total indicator runout (TIR) at the cutting edge should not exceed 0.01 mm for optimal tool life and hole quality.
