Grade Details - Key Grade Characteristics
The PR2005 grade is built on an ultrafine-grain carbide substrate (0.5 μm grain size) delivering high hardness (~92 HRA) and superior transverse rupture strength. The Diamond coating coating provides:
- Exceptional thermal stability up to 911°C
- Low coefficient of friction for reduced built-up edge
- High oxidation resistance for dry machining applications
- Superior adhesion strength preventing premature flaking
Grade Comparison Matrix
| Grade | Coating | Best For | Hardness |
|---|---|---|---|
| PR2005 | Diamond coating | composite materials, CFRP | 92 HRA |
| PR1535 | AlTiCrN PVD multi-layer | steel machining, stainless steel | 91 HRA |
| PR1725 | TiAlN PVD | cast iron machining, hardened steel | 93 HRA |
| PR1225 | Diamond-like carbon (DLC) | aluminum machining, non-ferrous | 91.5 HRA |
Chipbreaker Profile
The single-flute geometry features a high-positive rake angle of 12° with a polished flute surface for excellent chip flow. The chipbreaker groove is precision-ground to ensure:
- Controlled chip curling and segmentation
- Reduced cutting heat accumulation
- Minimal burr formation at exit
- Stable chip evacuation in blind-hole applications
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability |
|---|---|---|
| Aluminum (AlSi10Mg) | P.1 | Excellent |
| Brass (CuZn37) | P.2 | Very Good |
| Copper (Cu) | M.1 | Good |
| Plastics (PEEK) | K.2 | Very Good |
| Acrylic (PMMA) | P.3 | Good |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Ideal chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | Use peck cycle recommended |
| Stack Drilling | ★★★★☆ | Stable entry/exit behavior |
| Cross-Hole Intersection | ★★★☆☆ | Reduce feed by 30% |
| Inclined Entry | ★★★☆☆ | Use spot drill first |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) |
|---|---|---|
| Carbon Steel | 80-150 | 0.02-0.05 |
| Alloy Steel | 70-140 | 0.02-0.05 |
| Stainless Steel | 60-130 | 0.08-0.15 |
| Cast Iron | 90-160 | 0.12-0.22 |
| Aluminum | 120-200 | 0.15-0.30 |
Values are starting recommendations. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing.
Operating Guidelines
- Ensure spindle runout is less than 0.01 mm at the tool tip
- Use high-pressure coolant (external) delivery for optimal chip evacuation
- Maintain coolant concentration at 8-10% for water-miscible fluids
- Inspect tool point after every 50 holes in abrasive materials
- Replace tool when flank wear exceeds 0.15 mm or chipping is visible
- For standard drilling, use peck cycle with 1×D depth increments
