Product Overview
The Kyocera 4,1 PR1535 SGS64811 is a premium solid carbide drill engineered for high-performance CNC machining. Featuring a 4.1 mm diameter with 3-flute geometry and 5XD flute length, this long-reach through-coolant tool is optimized for deep-hole precision drilling in demanding production environments. Built to exacting OEM standards, it delivers exceptional dimensional accuracy, superior surface finish, and extended tool life across a broad spectrum of workpiece materials.
Through-Coolant (TB) Design: The internal coolant channels deliver coolant directly to the cutting edge at pressures up to 150 bar, ensuring superior chip evacuation in deep-hole applications up to 5×D. This is essential for maintaining hole quality and preventing chip packing in long-reach operations.

Chipbreaker Profile
The 4.1 mm drill features an optimized 3-flute chipbreaker geometry designed for efficient chip evacuation and reduced cutting forces:
- Chipbreaker Type: Double-rake positive geometry with polished flute surface
- Rake Angle: 12° positive rake for reduced cutting pressure
- Chip Groove Width: 1.43 mm
- Chip Curl Radius: Optimized for short, controllable 6-9 mm curl segments
- Flute Polishing: Mirror-polished (Ra 0.05 μm) to minimize built-up edge and friction
- Edge Preparation: Micro-honed T-land (0.03 mm × 20°) for edge stability
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Hardness | Suitability |
|---|---|---|---|
| Carbon Steel | P.1-P.3 | < 30 HRC | ★★★★★ Excellent |
| Alloy Steel | P.4-P.6 | 30-45 HRC | ★★★★★ Excellent |
| Stainless Steel (Austenitic) | M.1-M.2 | < 280 HB | ★★★★☆ Very Good |
| Stainless Steel (Martensitic) | M.3-M.4 | < 35 HRC | ★★★★☆ Very Good |
| Cast Iron (Gray) | K.1-K.2 | 180-260 HB | ★★★☆☆ Good |
| Tool Steel | P.7-P.9 | 30-50 HRC | ★★★★☆ Very Good |
Application Map by Operation
| Operation | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-hole Drilling | ★★★★★ | 5×D (standard) | Optimal chip evacuation |
| Blind-hole Drilling | ★★★★☆ | 5×D | Ensure adequate peck cycle |
| Stack Drilling | ★★★☆☆ | 1.5×D per plate | Use reduced feed |
| Cross-hole Drilling | ★★★☆☆ | 1×D | Reduce Vc by 20% |
| Enlarging | ★★★★☆ | 0.5×D step | Excellent hole quality |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Low-Carbon Steel (C15-C35) | 78 - 93 | 0.12 - 0.17 | Emulsion (8-10%) |
| Medium-Carbon Steel (C40-C55) | 68 - 83 | 0.1 - 0.15 | Emulsion (8-10%) |
| Alloy Steel (42CrMo4, 16MnCr5) | 58 - 73 | 0.09 - 0.12 | Emulsion or Oil |
| Austenitic Stainless Steel (304, 316) | 48 - 63 | 0.08 - 0.11 | High-pressure coolant |
| Gray Cast Iron (GG25, GG30) | 73 - 88 | 0.14 - 0.18 | Dry or compressed air |
Operating Guidelines
- Peck Cycle: For depths > 2×D, use peck drilling with retract to 1×D after every 0.5×D advance
- Coolant Pressure: Through-tool coolant (TB) mandatory for optimal chip evacuation
- Runout Tolerance: Maximum 0.01 mm at 3×D projection; use precision collet or hydraulic chuck
- Entry Angle: Ensure perpendicular entry; use spot drill or chamfer if angle > 2°
- Speed Ramp: Reduce spindle speed by 30% for first 2 mm entry, then ramp to full Vc
- Tool Life Reference: Expect 15-25 minutes of cutting time in steel at recommended parameters before edge wear reaches 0.15 mm flank wear
- Re-sharpening: Not recommended; solid carbide construction is designed for single-use precision
Toolholder Compatibility
| Holder Type | Clamping Range | Runout | Recommended |
|---|---|---|---|
| Hydraulic Chuck (Hydro) | 4.1 mm | < 0.003 mm | ★★★★★ Primary choice |
| Precision Collet (ER16-ER25) | 4.1 mm | < 0.010 mm | ★★★★☆ Good alternative |
| Shrink Fit Chuck | 4.1 mm | < 0.003 mm | ★★★★★ Excellent rigidity |
| Weldon Side-Lock | 4.1 mm | < 0.020 mm | ★★☆☆☆ Not recommended for precision |
