Chipbreaker Profile
The SGM08089 features an optimized 2-flute micro geometry with a precision-ground chipbreaker designed specifically for steel machining at micro-scale. The parabolic flute profile ensures efficient chip evacuation from deep micro-holes, reduces cutting forces by up to 20%, and minimizes built-up edge (BUE) formation. The polished flute surface (Ra 0.1 μm) and through-coolant (TA) channels enhance chip flow and prevent material adhesion during high-speed micro-machining operations.

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole Micro Drilling | ★★★★★ | Optimal chip evacuation with TA coolant |
| Blind-hole Micro Drilling | ★★★★☆ | Use peck cycle for depths >3xD |
| Stack Micro Drilling | ★★★★☆ | Ensure proper clamping and alignment |
| Cross-hole Micro Drilling | ★★★☆☆ | Reduce feed by 40% at intersection |
| Enlarging | ★★☆☆☆ | Not recommended as primary use |
Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed f (mm/rev) | Depth of Cut ap |
|---|---|---|---|
| Carbon Steel | 15-35 | 0.02-0.06 | 1.0-2.0xD |
| Alloy Steel | 12-30 | 0.02-0.05 | 1.0-2.0xD |
| Stainless Steel | 8-22 | 0.02-0.04 | 1.0-2.0xD |
| Cast Iron | 15-35 | 0.03-0.07 | 1.0-2.5xD |
Operating Guidelines
- Always use high-pressure through-coolant (minimum 100 bar) for micro-drilling depths exceeding 2xD to ensure proper chip evacuation and heat dissipation from the cutting edge.
- Maintain ultra-rigid toolholder and workpiece clamping. Minimum recommended spindle runout: 0.003 mm at the tool tip for micro-drills.
- For peck drilling cycles on micro-holes, use a retract value of 0.1-0.2 mm and reduce feed by 30% at each peck entry to prevent drill breakage.
- Ensure coolant concentration of 8-12% for water-miscible fluids; use neat oil for difficult-to-machine materials at micro-scale.
- Inspect tool wear after every 20 holes; replace when flank wear exceeds 0.01 mm or when burr formation increases at hole exit.
- Store micro tools in original packaging at 15-25°C with humidity below 50% to prevent corrosion of the precision ground edges.
