Chipbreaker Profile
This 0.8 mm drill utilises a Helical parabolic flute with reinforced core profile with a polished rake face and optimised land width. The flute geometry produces short, manageable chips that evacuate efficiently through the helical channel, preventing packing and reducing the risk of hole wall damage. A secondary margin land provides stabilising support during breakthrough, ensuring exit burr minimisation.
- Rake angle: 12°–14° (positive)
- Margin width: 0.08–0.12 mm
- Flute surface finish: Ra 0.2 µm (polished)
- Core thickness ratio: 0.35 × Dc
Recommended Applications & Workpiece Materials
The TA grade substrate and point geometry make this tool ideally suited for:
- Carbon steel (≤ 45 HRC) — Excellent chip control and tool life
- Alloy steel — Stable cutting with minimal burr formation
- Cast iron — High-speed capability with abrasion resistance
- Mild stainless steels — Compatible with reduced parameter sets
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | ★★★★★ | Primary design intent; optimised exit geometry |
| Blind-hole Drilling | ★★★★☆ | Ensure adequate coolant flow for chip evacuation |
| Spot Drilling | ★★★☆☆ | Use reduced feed to protect point geometry |
| Cross-hole Drilling | ★★★☆☆ | Reduce speed by 20% at intersection |
| Stack Drilling | ★★★★☆ | Clamp plates firmly; use peck cycle |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel (C45) | 80-120 | 0.05-0.15 | Emulsion / MQL |
| Alloy Steel (42CrMo4) | 70-110 | 0.05-0.15 | Emulsion |
| Stainless Steel (304) | 60-90 | 0.03-0.10 | High-pressure emulsion |
| Cast Iron (GG25) | 100-140 | 0.08-0.18 | Air blast / MQL |
| Aluminium (AlSi10Mg) | 150-250 | 0.06-0.15 | Air blast / UNIST |
Operating Guidelines
- Spindle Speed (n): Calculate from Vc = π × Dc × n / 1000. For 0.8 mm at 80 m/min, start at approximately 31831 RPM.
- Peck Cycle: Recommended for depths > 3×Dc. Initial peck = 1×Dc, subsequent pecks = 0.5×Dc, retract to clear chips.
- Coolant Pressure: Minimum 20 bar for through-tool coolant; 10 bar acceptable for external flood coolant in shallow holes.
- Run-out Tolerance: Maintain < 0.01 mm TIR at the tool point to prevent premature corner chipping.
- Entry Angle: Use a 90° entry surface or spot-drill to < 0.1 mm depth to protect the chisel edge.
- Tool Life Indicator: Monitor flank wear (VB). Resharpen or replace when VB = 0.15 mm or when burr height exceeds 0.05 mm.
Toolholder Compatibility
| Holder Type | Collet / Bore Size | Max Run-out | Recommended |
|---|---|---|---|
| ER Collet Chuck | ER11 (≤ 3 mm) or ER16 | 0.015 mm | General purpose |
| Hydraulic Expansion Chuck | HSK-A63 / BT40 taper | 0.003 mm | ★★★★★ High precision |
| Shrink Fit Chuck | 3.0 mm bore | 0.002 mm | ★★★★★ Best for micro-drilling |
| Weldon Side-lock | 3.0 mm | 0.020 mm | Not recommended for < 2 mm drills |
