Chipbreaker Profile
The DJ micro type chipbreaker geometry is engineered for optimal chip control in 3xD drilling operations. Features include:
- Positive rake angle design for reduced cutting forces and minimized burr formation
- Wide chip pocket volume to prevent chip packing in deep-hole applications
- Polished surface finish (Ra 0.2 μm) to reduce built-up edge and improve surface quality
- Optimized edge preparation: T-land + honed edge (0.03 mm) for edge stability
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Hardness Range | Performance Rating |
|---|---|---|---|
| Carbon Steel / Alloy Steel | P.1 – P.4 | ≤ 350 HB | ★★★★★ |
| Stainless Steel (Austenitic) | M.1 – M.2 | ≤ 280 HB | ★★★★☆ |
| Cast Iron (Gray / Ductile) | K.1 – K.3 | ≤ 300 HB | ★★★★☆ |
| Tool Steel (Pre-hardened) | P.5 – P.6 | 30 – 48 HRC | ★★★☆☆ |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | Excellent | Recommended primary application |
| Blind-hole Drilling | Good | Ensure adequate chip evacuation |
| Stack Drilling | Fair | Use reduced feed rates |
| Cross-hole Intersection | Good | Reduce speed by 20% at intersection |
| Inclined Entry / Exit | Fair | Use pilot hole or reduced feed |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Low-Carbon Steel (C < 0.25%) | 120 – 150 m/min | 0.15 – 0.25 mm/rev | 9.0 mm max |
| Medium-Carbon Steel (0.25 – 0.60%) | 100 – 130 m/min | 0.12 – 0.20 mm/rev | 9.0 mm max |
| Alloy Steel (Annealed) | 80 – 110 m/min | 0.10 – 0.18 mm/rev | 9.0 mm max |
| Stainless Steel 304/316 | 60 – 90 m/min | 0.10 – 0.16 mm/rev | 9.0 mm max |
| Gray Cast Iron (HB 180 – 220) | 90 – 120 m/min | 0.15 – 0.22 mm/rev | 9.0 mm max |
Operating Guidelines
- Coolant: High-pressure coolant (≥ 3 MPa / 435 psi) is strongly recommended for 3xD applications to ensure effective chip evacuation and heat dissipation.
- Peck Cycle: For depths exceeding 3xD, use a peck cycle with 1.5×D peck depth and full retract to break chips.
- Entry Surface: Ensure flat, perpendicular entry surface. Chamfer or center-drill inclined surfaces to prevent insert chipping.
- Tool Runout: Maintain total indicated runout (TIR) ≤ 0.02 mm at the tool tip for optimal hole straightness and surface finish.
- Edge Inspection: Inspect insert cutting edges after every 50 holes or 30 minutes of cutting time, whichever comes first.
- Replacement Criterion: Replace insert when flank wear (VB) exceeds 0.30 mm or when burr formation becomes excessive.
Toolholder Compatibility
| Holder Series | Diametric Range | Interface | Coolant Capability |
