Product Overview
The Kyocera 15/32 TB SGS54826 is a premium solid carbide drill engineered for die & mold production. Manufactured in Japan to exacting ISO standards, this 3-flute, 5×D through-coolant drill delivers exceptional hole quality, superior chip evacuation, and extended tool life in demanding production environments. The optimized point geometry minimizes cutting forces and reduces burr formation, ensuring consistent performance across high-volume manufacturing runs.

Chipbreaker Profile
The proprietary chipbreaker geometry on the 15/32 TB SGS54826 is designed to produce short, manageable chips even at high feed rates. The optimized land width and rake angle combination ensures:
- Reduced cutting pressure on the drill point
- Improved chip flow through the 3-flute gullet
- Minimized built-up edge (BUE) on stainless and sticky materials
- Consistent chip formation across the recommended speed/feed window

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Optimal chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | Peck cycle recommended |
| Stack Drilling | ★★★☆☆ | Use reduced feed |

| Enlarging | ★★★★☆ | Up to 1.5×D pre-hole |
Recommended Cutting Conditions
| Material | Vc (m/min) | fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel | 85 – 127 | 0.109 – 0.214 | Emulsion / MQL |
| Alloy Steel | 75 – 112 | 0.109 – 0.214 | Emulsion (8–10%) |
| Stainless Steel | 65 – 102 | 0.089 – 0.194 | High-pressure coolant |
| Cast Iron | 95 – 142 | 0.129 – 0.234 | Dry / Air blast |
| Aluminum | 125 – 177 | 0.139 – 0.254 | MQL / Air |
Operating Guidelines
- Run-out: Ensure spindle run-out is less than 0.01 mm at the tool tip to prevent uneven wear.
- Coolant Pressure: Maintain minimum 70 bar (1,000 psi) for through-tool coolant to guarantee adequate chip evacuation in 5×D applications.
- Peck Cycle: For blind holes deeper than 3×D, use a peck depth of 1–1.5×D with full retract to break chips.
- Toolholder: Use hydraulic or shrink-fit holders; collet holders are not recommended for 5×D drills.
- Entry Surface: Chamfer or spot-drill inclined surfaces to prevent drill walk and corner chipping.
- Re-sharpening: Not recommended; these solid carbide drills are designed as disposable tools for maximum consistency.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| Hydraulic Chuck | ✓ Full | Best for 5×D drills – excellent damping |
| Shrink Fit | ✓ Full | Ideal for high-speed applications |
| Milling Chuck | △ Limited | Acceptable for lower speeds only |
| ER Collet | ✗ Not Recommended | Insufficient rigidity for 5×D |
| Weldon Shank | ✓ Full | Secure side-lock for heavy cuts |
