Product Overview
The Kyocera DRILL PR1225 SGM06076 is a #29mm diameter solid carbide drill engineered for high-performance CNC machining. Featuring a 140° point angle and 2FL-flute design, this tool delivers exceptional hole quality, dimensional accuracy, and extended tool life in demanding production environments. The PR1225 (TiAlN PVD) coating minimizes built-up edge and ensures stable machining across a wide range of ferrous and non-ferrous materials.

Chipbreaker Profile
The SGM06076 features an optimized chipbreaker geometry designed for #29mm diameter drilling. The flute profile incorporates a variable helix design with polished rake surfaces to ensure smooth chip evacuation and minimize cutting forces. The chipbreaker width is calibrated to produce short, manageable chips in steel and stainless steel applications, reducing the risk of chip packing and hole distortion.
- Variable helix angle (30° ± 2°) for harmonic vibration suppression
- Polished flute surface (Ra 0.2 μm) for reduced friction and built-up edge resistance
- Optimized chipbreaker width for short-segment chip formation
- Reinforced core diameter for enhanced rigidity in deep-hole applications
Recommended Applications & Workpiece Materials
| Material Group | Examples | Machinability |
|---|---|---|
| P - Steel | C45, 42CrMo4, 16MnCr5, 100Cr6 | ★★★★★ Excellent |
| M - Stainless Steel | 304, 316, 17-4PH, 15-5PH | ★★★★☆ Very Good |
| K - Cast Iron | GG25, GGG50, CGI | ★★★★☆ Very Good |
| N - Non-Ferrous | Aluminum 7075, Brass CuZn37 | ★★★☆☆ Good |
Application Map by Operation
| Operation | Suitability | Depth (L/D) |
|---|---|---|
| Through-hole Drilling | ✓ Recommended | Up to 5xD |
| Blind-hole Drilling | ✓ Recommended | Up to 3xD |
| Stack Drilling | ✓ Suitable | Up to 2xD |
| Enlarging / Reaming | ○ Possible with reduced feed | Up to 1.5xD |
| Trepanning | ✗ Not Recommended | — |
Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel (C45) | 70-110 | 0.10-0.18 | Emulsion 8-10% |
| Alloy Steel (42CrMo4) | 59-104 | 0.10-0.18 | Emulsion 8-10% |
| Stainless Steel (304) | 52-93 | 0.09-0.16 | Emulsion 10-12% |
| Cast Iron (GG25) | 77-137 | 0.11-0.2 | Dry / MQL |
Operating Guidelines
- Pecking Cycle: For depths exceeding 3xD, use a peck depth of 1-1.5xD with full retract to break chips.
- Coolant Pressure: Maintain minimum 20 bar (290 psi) internal coolant pressure for effective chip evacuation.
- Tool Runout: Ensure spindle runout is less than 0.01 mm TIR for optimal hole quality and tool life.
- Entry Angle: Use a chamfer or center drill to prevent walk-off on inclined surfaces greater than 5°.
- Pre-drilling: Not required for standard applications; tool is self-centering at 140° point angle.
- Speed Ramp: Reduce spindle speed by 20% for the first 10 mm of engagement to prevent thermal shock.
