Product Overview
The Kyocera 1/4 2FL 3XD TX IC Solid Carbide Drill (SGS58823) is a precision-engineered holemaking tool designed for deep-hole CNC machining in steel, stainless steel, and cast iron applications. Manufactured in Japan to exacting OEM standards, this 1/4 diameter drill features a 2-flute design with 3×D flute length, optimized for extended reach drilling with stable chip evacuation and superior hole quality in through-hole and blind-hole operations.
With its advanced TX-grade PVD coating and proprietary point geometry, the SGS58823 delivers reduced cutting forces, extended tool life, and consistent dimensional accuracy across high-volume production environments. The IC (internal coolant) capability enhances chip flushing and heat dissipation in deep-hole applications.

Grade Details — Key Grade Characteristics
The TX Grade is a premium submicron carbide substrate featuring a multi-layer TiAlN PVD coating engineered specifically for high-speed drilling in ferrous materials. Key characteristics include:
- Substrate: Ultra-fine grain WC-Co (12% Co) for high toughness and edge stability
- Coating: Nano-structured TiAlN PVD layer (3–4 µm) with exceptional thermal stability up to 900°C
- Hardness: 1,650 HV (substrate) / 3,200 HV (coating)
- Transverse Rupture Strength: 3,800 MPa
- Oxidation Resistance: Superior red-hardness for dry and MQL machining
- Friction Coefficient: 0.35–0.40 (reduces built-up edge in steel)
Grade Comparison Matrix
| Grade | Coating | Primary Material | Max Speed (m/min) | Best For |
|---|---|---|---|---|
| TX | TiAlN PVD | Steel, Cast Iron | 100 | High-speed, general purpose |
| PV7020 | TiAlN + TiN | Stainless Steel | 80 | Corrosion-resistant alloys |
| CA6535 | TiCN | Carbon Steel | 70 | Economical high-volume jobs |
| PR1535 | AlCrN | Hardened Steel (>45 HRC) | 60 | Hard material drilling |
Point Geometry & Chipbreaker Profile
The SGS58823 utilizes a thinned-web 140° split-point geometry with a proprietary margin design that minimizes wandering on entry and reduces thrust forces by up to 25% compared to standard chisel-edge drills. The internal coolant (IC) channels are strategically positioned to direct coolant directly to the cutting edges for optimal heat dissipation in deep-hole applications.
| Geometry Feature | Specification | Performance Benefit |
|---|---|---|
| Point Angle | 140° with web thinning | Self-centering, reduced walk-off |
| Margin Width | 12% of diameter | Stable wall contact, improved hole straightness |
| Helix Angle | 30° | Efficient chip evacuation in deep holes |
| Chipbreaker | Parabolic flute with polished gash | Small, manageable chip segments |
| Edge Prep | T-land + hone (0.03 mm) | Edge strength without micro-chipping |
| Coolant Channels | 2 internal through-coolant holes | Direct coolant to cutting edge, improved chip flushing |
Recommended Applications & Workpiece Materials
- Carbon Steel: 1018, 1045, A36 (up to 300 HB)
- Alloy Steel: 4140, 4340, 8620 (pre-hardened up to 32 HRC)
- Cast Iron: Gray cast iron (GJL-250), ductile iron (GJS-500)
- Stainless Steel: 304, 316 (moderate speeds recommended)
- Tool Steel: O1, A2, D2 (annealed condition)
Not recommended: Titanium alloys, nickel-based superalloys (Inconel), or hardened steels above 45 HRC without specialized grade selection.
Application Map by Operation
| Operation Type | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | 3×D | Optimal chip evacuation |
| Blind-Hole Drilling | ★★★★☆ Very Good | 3×D | Use peck cycle for deep holes |
| Enlarging / Reaming | ★★★☆☆ Good | 1×D | Reduce feed by 30% |
| Spot Drilling | ★★★★☆ Very Good | 0.5×D | Split point self-centers |
| Deep Hole Drilling | ★★★★☆ Very Good | 3×D | Internal coolant essential |
Recommended Cutting Conditions
Parameters below are starting recommendations for medium-carbon steel (1045) using internal coolant (IC) delivery. Adjust based on machine rigidity, workpiece fixturing, and coolant pressure.
| Parameter | Value | Notes |
|---|---|---|
| Cutting Speed (Vc) | 80–100 m/min | Reduce 20% for stainless steel |
| Spindle Speed (n) | 4,010 RPM | Calculated for 6.35 mm diameter |
| Feed per Revolution (fn) | 0.25 mm/rev | 0.1–0.15 × D for steel |
| Feed per Tooth (fz) | 0.125 mm/tooth | 2-flute design |
| Peck Depth | 1.0–1.5 × D | Essential for blind holes >2×D |
| Coolant Pressure | 70–100 bar (IC) | Minimum 50 bar for effective chip flushing |
| Coolant Type | 5–8% soluble oil emulsion | Or synthetic for stainless steel |
Operating Guidelines
- Tool Runout: Maintain TIR ≤ 0.01 mm at the tool point. Excessive runout accelerates corner wear and reduces hole tolerance.
- Entry Angle: Ensure workpiece surface is perpendicular to spindle axis within 0.5°. Use a spot drill or center drill for irregular surfaces.
- Peck Cycle: For depths exceeding 2.0×D, implement a full-retract peck cycle to clear chips and allow coolant penetration. Recommended peck depth: 1.0–1.5×D.
- Chip Control: Monitor chip color. Blue or straw-colored chips indicate optimal heat transfer. Dark blue or black chips signal excessive heat—reduce speed or increase feed.
- Coolant Filtration: Maintain coolant filtration at 25 µm or finer to prevent clogging of internal coolant channels.
- Tool Change Criteria: Replace the drill when flank wear (VB) reaches 0.15 mm, or when burr formation on the exit edge becomes excessive.
- Re-sharpening: Not recommended. These solid carbide drills are designed as disposable precision tools. Re-sharpening alters the web thinning and coating integrity.
Toolholder Compatibility
| Holder Type | Compatibility | Clamp Force | Runout Capability |
|---|---|---|---|
| Hydraulic Chuck (HSK-A63) | ★★★★★ Excellent | High, uniform | ≤ 0.005 mm TIR |
| Shrink Fit (HSK-A63) | ★★★★★ Excellent | Very high | ≤ 0.003 mm TIR |
| ER Collet (ER25/ER32) | ★★★★☆ Very Good | Medium-high | ≤ 0.010 mm TIR |
| Drill Chuck (Keyless) | ★★★☆☆ Good | Medium | ≤ 0.020 mm TIR |
Note: For optimal performance and hole quality, use hydraulic or shrink-fit holders. ER collets are acceptable for general-purpose work; standard drill chucks should be reserved for manual operations only.
