Grade Details - Key Grade Characteristics
The TX grade features Kyocera's proprietary micrograin carbide substrate (0.8 μm grain size) paired with a multi-layer AlTiN PVD coating. This combination delivers optimal hardness, toughness, and thermal stability for high-speed drilling.
| Property | Value | Test Method |
|---|---|---|
| Co-Hardness (HV30) | 1,650 ± 50 | ISO 3878 |
| Transverse Rupture Strength | 3,800 MPa | ISO 3327 |
| Coating Thickness | 2.5 ± 0.5 μm | Calotest |
| Coating Hardness (HV) | 3,200 ± 200 | Nanoindentation |
| Oxidation Resistance | 900°C | TGA Analysis |
Grade Comparison Matrix
Comparative analysis of TX grade against alternative Kyocera grades:
| Grade | Coating | Hardness | Toughness | Best For |
|---|---|---|---|---|
| TX | AlTiN | Very High | High | Universal drilling (steel, stainless, cast iron) |
| PR1535 | TiAlN | Extreme | Medium | High-speed steel, abrasive materials |
| CA6535 | TiSiN | High | Very High | Stainless, titanium, interrupted cuts |
| GW15 | Diamond | Ultra-High | Low | Aluminum, copper, composites |
Chipbreaker Profile
Solid carbide drills utilize advanced flute geometry to control chip formation and evacuation. The parabolic flute profile is optimized for the 5×D length-to-diameter ratio.
| Parameter | Specification | Functional Benefit |
|---|---|---|
| Flute Profile | Parabolic (35% core) | Maximized chip pocket volume for deep-hole drilling |
| Flute Surface Finish | Ra 0.2 μm | Reduced friction and chip adhesion |
| Helix Angle | {helix_angle}° | Balanced axial and radial force distribution |
| Radial Rake Angle | 8° positive | Reduced cutting forces, improved surface finish |
| Core Taper | 1:50 toward shank | Enhanced rigidity and chip transport |
| Margin Design | Dual margin, 0.15 mm | Improved hole straightness and stability |
Recommended Applications & Workpiece Materials
The TX grade and 2-flute geometry make this drill suitable for a broad spectrum of ISO material groups:
| ISO Group | Material | Hardness | Suitability |
|---|---|---|---|
| P.1 | Low-carbon steel (C < 0.25%) | < 180 HB | ★★★★★ Excellent |
| P.2 | Medium-carbon steel (0.25-0.55% C) | 180-280 HB | ★★★★★ Excellent |
| P.3 | High-carbon steel, alloy steel | 280-350 HB | ★★★★☆ Very Good |
| M.1 | Austenitic stainless steel | < 200 HB | ★★★★☆ Very Good |
| M.2 | Ferritic/martensitic stainless | 200-320 HB | ★★★★☆ Very Good |
| K.1 | Grey cast iron (GG/GJL) | 180-260 HB | ★★★★★ Excellent |
| K.2 | Nodular cast iron (GGG/GJS) | 200-300 HB | ★★★★☆ Very Good |
| N.1 | Aluminum alloys (wrought) | < 100 HB | ★★★★☆ Very Good |
Application Map by Operation
| Operation Type | Suitability | Max Depth | Recommended Conditions |
|---|---|---|---|
| Through-hole drilling | ★★★★★ Ideal | 5×D (standard) | Standard feed/speed |
| Blind hole drilling | ★★★★★ Ideal | 5×D | Reduce feed 20% at bottom |
| Peck drilling (deep hole) | ★★★★☆ Good | Up to 8×D with peck | Peck depth 1-1.5×D |
| Stack drilling | ★★★★☆ Good | Per plate thickness | Clamp plates securely |
| Helical interpolation | ★★★☆☆ Fair | Hole > 1.5×D | Reduce radial engagement |
| Micro-pooling | ★★★★★ Ideal | 5×D | Min. 20 bar coolant pressure |
Recommended Cutting Conditions
Optimized parameters for 5,5 mm diameter. Values are starting recommendations; adjust based on machine rigidity and workpiece stability.
| Material | Vc (m/min) | fz (mm/rev) | RPM (n) | Feed (mm/min) |
|---|---|---|---|---|
| Steel (P.1-P.2) | 99 | 0.147 | 5729 | 842.0 |
| Stainless (M.1-M.2) | 74 | 0.118 | 4282 | 505.0 |
| Cast Iron (K.1-K.2) | 119 | 0.177 | 6887 | 1219.0 |
| Non-ferrous (N.1) | 173 | 0.216 | 10012 | 2163.0 |
Operating Guidelines
- Coolant: Use water-soluble coolant (5-8% concentration) or neat oil. Minimum pressure 20 bar for through-tool delivery.
- Peck Cycle: For depths > 3×D, use peck depth of 1.0-1.5×D. Full retract every 3 pecks for chip clearing.
- Entry Angle: Use chamfer or center drill for entry. Avoid direct entry on inclined surfaces > 5°.
- Speed/Feed: Start at 80% of recommended Vc for first 50 holes, then increase to 100%.
- Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB = 0.3 mm or edge chipping appears.
- Rigidity: Ensure workpiece clamping and spindle runout < 0.01 mm for optimal hole tolerance.
