Kyocera #28 2XD TX SGS58490 — Precision Carbide DRILL
Product Overview
The Kyocera #28 2XD TX SGS58490 is a premium-grade solid carbide drill engineered for tool steel machining. Featuring a 2FL flute design 2XD length-to-diameter ratio and AlCrN + TiSiN nano-composite PVD coating, this tool delivers exceptional hole quality, dimensional accuracy, and extended tool life in demanding CNC environments. The optimized point geometry minimizes thrust forces and ensures stable entry, making it ideal for high-volume production and precision engineering applications.

Chipbreaker Profile
TX Chipbreaker Geometry: Variable helix design with AlCrN-coated edge for extreme heat resistance and reduced built-up edge
- Flute surface polished to Ra ≤ 0.20 μm for superior chip flow
- Optimized helix angle (32°) balances chip evacuation and tool rigidity
- Reinforced corner radius (0.02 mm) prevents chipping on exit
- Internal coolant channels (where applicable) deliver high-pressure coolant directly to cutting edge
Recommended Applications & Workpiece Materials

Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Optimized point geometry ensures clean breakthrough |
| Blind-Hole Drilling | ★★★★☆ | Use peck cycle; excellent chip evacuation |
| Stack Drilling | ★★★★☆ | Stable margin design prevents burr formation |
| High-Speed CNC | ★★★★★ | Balanced for spindle speeds up to 20,000 RPM |
| Micro-Drilling | ★★★☆☆ | Suitable for holes ≥ 0.5 mm diameter |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap |
|---|---|---|---|
| Mild Steel (≤ 250 HB) | 85-105 | 0.15-0.25 | 1.0-2.0D |
| Alloy Steel (250-350 HB) | 75-95 | 0.12-0.20 | 0.8-1.5D |
| Stainless Steel | 65-85 | 0.10-0.18 | 0.5-1.2D |
| Cast Iron (≤ 300 HB) | 95-115 | 0.18-0.28 | 1.0-2.5D |
| Aluminum Alloy | 125-165 | 0.20-0.35 | 1.5-3.0D |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece clamping. Use internal coolant (10–70 bar) where possible.
Operating Guidelines
- Coolant: Use water-soluble coolant (8–10% concentration) or neat oil for titanium and nickel alloys. Minimum coolant pressure: 10 bar for holes > 3×D.
- Peck Cycle: For holes > 3×D, use peck depth of 1–1.5×D with full retraction every 3×D to clear chips.
- Tool Overhang: Minimize overhang to ≤ 4×D for optimal stability and hole straightness.
- Entry Surface: Ensure flat, perpendicular entry surface. Chamfer or center-drill if surface is irregular.
- Speed/Feed Ramp: Reduce feed by 30% for the first 1 mm of entry; ramp to full feed after engagement.
- Tool Life Monitoring: Monitor flank wear (VB max = 0.3 mm). Replace tool when surface finish degrades or hole diameter exceeds tolerance.
Toolholder Compatibility
| Holder Type | Standard | Compatibility |
|---|---|---|
| Hydraulic Chuck | DIN 69871 / ISO 7388 | Excellent — best for high-speed applications |
| Shrink Fit Chuck | HSK-A63 / HSK-A100 | Excellent — maximum torque transmission |
| Collet Chuck (ER) | ER16 / ER20 / ER32 | Very Good — ensure runout ≤ 0.01 mm |
| Milling Chuck | DIN 1835-B | Good — suitable for general machining |
