Chipbreaker Profile
The #38 TN features a 2-flute standard twist geometry with polished flutes and a precisely ground margin. The chipbreaker design ensures:
- Controlled chip curl: Chips form tight spirals for easy evacuation
- Reduced cutting forces: Lower torque requirements and improved hole straightness
- Minimized built-up edge: TiN coating prevents material adhesion to the cutting edge
- Stable chip flow: Consistent chip breaking across steel, stainless steel, and cast iron
Recommended Applications & Workpiece Materials
| Material | Cutting Speed (m/min) | Feed (mm/rev) | Coolant Strategy |
|---|---|---|---|
| Carbon Steel (≤45 HRC) | 25 – 40 | 0.08 – 0.15 | External / Through-spindle |
| Alloy Steel (≤35 HRC) | 20 – 35 | 0.07 – 0.12 | External / Through-spindle |
| Stainless Steel (304/316) | 15 – 25 | 0.06 – 0.10 | Through-spindle preferred |
| Cast Iron (GG25/GGG50) | 30 – 50 | 0.10 – 0.18 | External / Dry machining |
| Aluminum Alloy (≤12% Si) | 60 – 100 | 0.10 – 0.20 | External / MQL |
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | ★★★★★ | Ideal for blind and through holes up to 5×D |
| Blind-hole Drilling | ★★★★★ | 140° point angle ensures clean bottom finish |
| Peck Drilling | ★★★★☆ | Use 1.5–2.0×D peck depth for deep holes |
| Enlarging / Reaming | ★★★☆☆ | Not recommended; use dedicated reamer |
| Countersinking | ★★☆☆☆ | Use dedicated countersink tool |
Recommended Cutting Conditions
| Condition | Value | Remarks |
|---|---|---|
| Cutting Speed (Vc) | 15 – 100 m/min | Material-dependent; start at lower end |
| Feed Rate (f) | 0.06 – 0.20 mm/rev | Higher feeds for softer materials |
| Spindle Speed (n) | 2,500 – 17,000 RPM | Calculated from Vc and diameter |
| Depth of Cut (ap) | 1 × D (full diameter) | Standard drilling engagement |
| Coolant Flow Rate | ≥ 8 L/min | Higher for stainless steel |
Operating Guidelines
| Parameter | Value | Note |
|---|---|---|
| Runout Tolerance | ≤ 0.01 mm at 3×D | Critical for hole accuracy and tool life |
| Coolant Pressure | ≥ 20 bar (through-tool) | Required for deep-hole drilling (>3×D) |
| Peck Depth | 1.5 – 2.0 × D | Standard peck cycle for chip breaking |
| Entry Angle / Chamfer | 90° ± 1° | Use spot drill or chamfer to prevent walk |
| Max Hole Depth | 5 × D | Standard flute length limitation |
| Spindle Warm-up | 5 min at 5,000 RPM | Before precision work to stabilize thermal expansion |
