Product Overview
The Kyocera 20,0 DRILL 2FL 2XD TX SGS67184 is a premium solid carbide drill engineered for high-performance CNC machining operations. Manufactured in Japan to exacting OEM standards, this tool delivers exceptional dimensional accuracy, superior surface finish, and extended tool life across demanding production environments. The 20,0mm diameter configuration with 2-flute geometry and 2×D flute length is optimized for large-diameter heavy-duty drilling in a wide range of ferrous and non-ferrous materials.

Grade Details — Key Grade Characteristics
The TX grade is a 0.5 μm micro-grain WC-Co (12% Co binder) with micro-grain tungsten carbide substrate with a multi-layer PVD coating engineered specifically for high-speed drilling applications. Key characteristics include:
- Substrate: 0.5 μm micro-grain WC-Co (12% Co binder) for superior toughness and edge stability for general-purpose drilling
- Coating: TiAlN-based multi-layer PVD with enhanced oxidation resistance up to 900°C
- Hardness: 1,650 HV (Vickers) for exceptional wear resistance
- Transverse Rupture Strength: 4,200 MPa — ideal for interrupted cuts and cross-hole drilling
- Surface Finish: Mirror-polished flute surfaces (Ra ≤ 0.2 μm) minimize built-up edge and friction
- Edge Preparation: Controlled honing (T-land) for chip flow optimization and micro-chipping prevention
Grade Comparison Matrix
| Grade | Coating | Best For | Max Speed (m/min) |
|---|---|---|---|
| TX (This Tool) | TiAlN-based multi-layer PVD | Steel, Stainless, Cast Iron | 120 |
| CA | TiN/TiAlN | General purpose, lower speeds | 90 |
| PR | AlCrN | Hardened steel (>50 HRC) | 80 |
| GW | Diamond-like Carbon | Aluminum, non-ferrous | 200 |
Chipbreaker Profile
While this is a solid carbide drill (not an indexable insert), the flute geometry incorporates an advanced chip-forming groove design that functions analogously to an insert chipbreaker:
- Flute Profile: Parabolic flute with variable core thickness for optimal chip curl and evacuation
- Chip Groove Depth: 0.35 × diameter — promotes tight chip curl without excessive cutting force
- Chip Form: Produces short, manageable C-type or 6-type chips in steel; 9-type in stainless
- Evacuation Channel: Polished flute surface (Ra 0.15 μm) with 8° rake angle for low-friction chip flow
- Coolant Through: Internal coolant channels (2 holes, 0.3 × diameter) direct high-pressure coolant to the cutting edge for effective chip flushing and thermal management
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Recommended |
|---|---|---|---|
| Carbon Steel (≤ 0.5% C) | P.1 / P.2 | Excellent | ✓ Primary application |
| Alloy Steel (≤ 42 HRC) | P.3 / P.4 | Very Good | ✓ Recommended |
| Stainless Steel (Austenitic) | M.1 / M.2 | Good | ✓ With reduced parameters |
| Cast Iron (Gray / Ductile) | K.1 / K.2 | Good | ✓ Suitable |
| Aluminum Alloy (Wrought) | N.1 / N.2 | Excellent | ✓ High-speed capable |
| Titanium Alloy (Ti-6Al-4V) | S.1 / S.2 | Moderate | △ Possible with care |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Optimal chip evacuation; use peck cycle for L/D > 3 |
| Blind-Hole Drilling | ★★★★☆ Very Good | Ensure adequate coolant flow; retract to clear chips |
| Cross-Hole Drilling | ★★★★☆ Very Good | TX grade toughness handles interrupted cuts |
| Stack Drilling | ★★★☆☆ Good | Reduce feed by 20% at interface transitions |
| Enlarging / Reaming | ★★☆☆☆ Fair | Not recommended; use dedicated reamer for tolerance |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Approx. RPM |
|---|---|---|---|
| Carbon Steel (P.1) | 56 | 0.210 | 891 |
| Alloy Steel (P.3) | 46 | 0.210 | 391 |
| Stainless Steel (M.1) | 42 | 0.168 | 668 |
| Cast Iron (K.2) | 57 | 0.198 | 1,468 |
| Aluminum Alloy (N.1) | 90 | 0.272 | 1,432 |
Note: Values are starting recommendations. Adjust based on machine rigidity, coolant concentration, and hole depth. For L/D > 3, reduce Vc by 15% and use peck drilling.
Operating Guidelines
- Coolant: Use water-miscible cutting fluid at 6–8% concentration, minimum 20 bar through-tool coolant or high-volume flood coolant. Flood coolant acceptable for shallow holes (L/D ≤ 2).
- Peck Cycle: For holes deeper than 3×D, use a peck depth of 1.0×D with full retract to break chips. For stainless steel, reduce peck depth by 20%.
- Entry Angle: When drilling inclined surfaces or curved entry, reduce feed to 50% for the first 1×D to prevent walk and chipping.
- Exit Strategy: Reduce feed by 30% in the last 2 mm before breakthrough to minimize burr formation and edge chipping.
- Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB reaches 0.3 mm or when burr formation increases noticeably.
- Storage: Store in original packaging at 15–25°C, humidity < 60% RH. Avoid contact between cutting edges to prevent micro-chipping.
Toolholder Compatibility
| Holder Type | Shank Fit | Recommended Torque | Runout Capability |
|---|---|---|---|
| Hydraulic Chuck (Hydro) | H6 precision bore | 25 Nm | ≤ 0.003 mm |
| Shrink Fit Holder | H6 interference | N/A (thermal) | ≤ 0.003 mm |
| Precision Collet (ER25/ER32) | H6 collet bore | 20 Nm | ≤ 0.010 mm |
| Weldon Side-Lock | Flat engagement | 30 Nm | ≤ 0.015 mm |
For best results and maximum tool life, Kyocera recommends using a hydraulic chuck or shrink-fit holder with maximum rigidity to minimize runout and maintain concentricity within 0.005 mm.
