Chipbreaker Profile
The 7/16 drill features an optimized 3-flute geometry with a proprietary chipbreaker design that ensures efficient chip formation and evacuation. The flute profile is engineered to produce short, manageable chips even at elevated feed rates, reducing the risk of chip packing and improving hole quality.
- Flute Form: Parabolic gash with polished rake surface for reduced friction
- Chipbreaker Type: Continuous micro-edge geometry along cutting lip
- Chip Control: Optimized for spiral/curled chip formation in ductile materials
- Evacuation Path: Wide flute gulley with polished surface finish (Ra 0.2 μm)
- Coolant Channels: Dual through-coolant ports delivering 20-30 bar pressure
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Recommendation |
|---|---|---|---|
| Carbon Steel (< 0.5% C) | P.1 | Excellent | Ideal - high speeds and feeds |
| Carbon Steel (> 0.5% C) | P.2 | Good | Recommended - reduce speed 10% |
| Alloy Steel (annealed) | P.3 | Good | Recommended |
| Stainless Steel (austenitic) | M.1 | Moderate | Suitable - use peck cycle |
| Gray Cast Iron | K.1 | Excellent | Ideal - excellent chip control |
| Ductile Cast Iron | K.2 | Good | Recommended |
| Aluminum Alloy (wrought) | N.1 | Excellent | Suitable - high speeds possible |
| Titanium Alloy | S.1 | Moderate | Possible - reduce parameters 30% |
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Primary application - optimized exit burr control |
| Blind-Hole Drilling | ★★★★☆ | Excellent - chip evacuation via coolant |
| Stack Drilling | ★★★★☆ | Recommended with proper clamping |
| Cross-Hole Drilling | ★★★☆☆ | Reduce feed by 20% at intersection |
| Enlarging / Reaming | ★★☆☆☆ | Not recommended - use dedicated reamer |
| Trepanning | ★☆☆☆☆ | Not suitable - solid drill design |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) | Feed per Rev (fn) | RPM Range |
|---|---|---|---|
| Mild Steel (P.1) | 35-55 m/min | 0.12-0.20 mm/rev | 8,731-13,097 |
| Stainless Steel (M.1) | 18-28 m/min | 0.08-0.12 mm/rev | 4,365-6,548 |
| Cast Iron (K.1) | 25-40 m/min | 0.10-0.15 mm/rev | 6,548-9,822 |
| Aluminum (N.1) | 80-120 m/min | 0.15-0.25 mm/rev | 17,462-26,194 |
Operating Guidelines
- Coolant Pressure: Maintain 20-30 bar (290-435 psi) for effective chip evacuation and tool cooling
- Peck Cycle: For depths > 3×D, use peck depth of 1.5-2×D with full retract to break chips
- Entry Angle: Ensure perpendicular entry (±0.5°) to prevent chipping and uneven wear
- Pre-Drill: For cast iron or interrupted surfaces, chamfer entry with 90° countersink
- Speed/Feed Ramp: Reduce feed by 30% for the first 2 mm of entry to stabilize cutting
- Tool Life Check: Monitor flank wear (VB); regrind or replace when VB exceeds 0.3 mm
- Surface Finish: For mirror finish requirements, reduce feed by 20% and increase speed by 10%
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck (HSK-A63) | ★★★★★ | Best damping - recommended for precision |
| Shrink Fit Holder | ★★★★★ | Excellent runout (< 3 μm at 3×D) |
| ER Collet Chuck (ER25/ER32) | ★★★★☆ | Suitable - ensure collet quality and torque |
| Milling Chuck | ★★★★☆ | Good for general machining |
| Drill Chuck (Keyless) | ★★☆☆☆ | Not recommended - excessive runout |
