Product Overview
The Kyocera #40 2FL DRILL (SGS50000) is a precision-engineered solid carbide drilling tool from the SGS micro-drill series. This through-coolant performance series variant is manufactured to exacting standards in Japan and delivers exceptional hole quality, dimensional accuracy, and surface integrity for high-performance through-coolant drilling in hardened steels, titanium alloys, nickel-based superalloys, and stainless steels. The #40 nominal diameter combined with tialn coated substrate ensures reliable performance in high-volume CNC production environments.

Application Map by Operation
| Operation | Suitable | Guidance |
|---|---|---|
| Through-Hole Drilling | ✓ Recommended | Primary application; use peck cycle for depths >3×D |
| Blind-Hole Drilling | ✓ Recommended | Ensure adequate chip evacuation with compressed air or MQL |
| Countersinking | △ Limited | Possible at reduced feed; not designed for large chamfers |
| Enlarging / Reaming | ✗ Not Recommended | Use dedicated reamer for tolerance IT7 and better |
| Trepanning | ✗ Not Recommended | Insufficient core strength for core retention |
Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap |
|---|---|---|---|
| Low-Carbon Steel (C<0.3%) | 25 – 50 | 0.04 – 0.1 | 5.0 – 10.0×D (up to 2.54mm) |
| Medium-Carbon Steel (0.3–0.6%) | 20 – 45 | 0.04 – 0.1 | 5.0 – 10.0×D (up to 2.54mm) |
| Stainless Steel (AISI 304) | 15 – 40 | 0.03 – 0.08 | 1.0 – 2.0×D |

Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece fixturing.
Operating Guidelines
- Run-out: Maintain TIR ≤0.01 mm at the tool tip to prevent premature corner wear and hole enlargement.
- Coolant: Through-spindle coolant (minimum 70 bar, 15 L/min) is mandatory. Use water-miscible coolant at 8–10% concentration or neat oil for best thermal management.
- Peck Cycle: Use 0.25×D peck depth for 8–10×D applications with full retraction to break chips. For <5×D, 0.5×D peck is acceptable.
- Entry Angle: Drill perpendicular to surface (90° ±1°). For inclined entry, use spot drilling or chamfering first.
- Speed / Feed Ramp: Reduce Vc by 20% and increase feed gradually over the first 5 mm to stabilize cutting forces.
- Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB ≥0.05 mm for precision applications.
Toolholder Compatibility
| Holder Type | Compatible | Recommendation |
|---|---|---|
| ER Collet Chuck (ER16 / ER20 / ER25) | ✓ Yes | Use AA-precision collet for best run-out control |
| Hydraulic Chuck | ✓ Yes | Recommended for high-speed applications; damping improves surface finish |
| Shrink-Fit Chuck | ✓ Yes | Excellent rigidity and torque transmission for demanding cuts |
| Weldon Flat Holder | ✗ No | Cylindrical shank without Weldon flat; use side-lock only with brass shim |
