Product Overview
The Kyocera SGS61116 is a precision-engineered solid carbide drill with a 9.1mm diameter and 2-flute design. Manufactured in Japan to exacting ISO standards, this drill is optimized for high-performance CNC machining across a broad spectrum of ferrous and non-ferrous materials. The SGS-grade substrate delivers exceptional wear resistance and thermal stability, ensuring consistent hole quality and extended tool life even under demanding production schedules.
With a 140° point angle and 30° helix geometry, the SGS61116 ensures efficient chip evacuation, reduced cutting forces, and minimal burr formation. Whether deployed in high-volume automotive production or precision aerospace component manufacturing, this tool provides the reliability and repeatability that modern machine shops demand.

Chipbreaker Profile
Although the SGS61116 is a solid carbide drill rather than an indexable insert, its flute geometry functions as an integrated chip control system. The 9.1mm diameter variant features a precisely ground flute profile with a rake angle optimized for the target material range.
| Geometric Feature | Specification | Chip Control Function |
|---|---|---|
| Flute Profile | Parabolic | Enhanced chip curl and evacuation in deep holes |
| Rake Angle (γ) | 12° | Reduces cutting force; minimizes built-up edge |
| Core Thickness Ratio | 22% | Balances rigidity with chip pocket volume |
| Margin Width | 0.12 × Dc | Stabilizes drill in cut; improves hole finish |
| Point Geometry | Split Point (S-point) | Self-centering; reduces thrust force by 40% |
Recommended Applications & Workpiece Materials
The 9.1 drill is validated for the following material groups and industrial applications:
| Material Group | Examples | Machinability | Recommended coolant |
|---|---|---|---|
| Carbon Steels | C45, C60, S355JR | Excellent | Emulsion / MQL |
| Alloy Steels | 42CrMo4, 4140, 4340 | Very Good | Emulsion / Oil |
| Stainless Steels | 304, 316, 17-4PH | Good | High-pressure emulsion |
| Cast Iron | GG25, GGG50, FC300 | Excellent | Dry / Compressed air |
| Aluminum Alloys | 6061, 7075, 2024 | Very Good | MQL / Air blast |
| Titanium Alloys | Ti-6Al-4V, Ti-5Al-5V | Good | High-pressure oil |
Application Map by Operation
| Operation Type | Suitability | Max Depth (Dc) | Notes |
|---|---|---|---|
| Through-hole Drilling | ★★★★★ | 3×Dc | Standard application; excellent chip evacuation |
| Blind-hole Drilling | ★★★★☆ | 2.5×Dc | Ensure adequate peck cycle for chip breaking |
| Stack Drilling | ★★★★☆ | 2×Dc | Use reduced feed at interface |
| Cross-hole Drilling | ★★★☆☆ | 1.5×Dc | Reduce speed by 20% at intersection |
| Enlarging / Reaming | ★★☆☆☆ | 1×Dc | Not recommended; use dedicated reamer |
Recommended Cutting Conditions
Parameters below are starting recommendations for stable machining centers with rigid toolholding. Adjustments may be required based on machine condition, workpiece fixturing, and coolant delivery pressure.
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | RPM (approx.) |
|---|---|---|---|
| Carbon Steel (≤ 0.45% C) | 67.1 | 0.123 | 2347 |
| Alloy Steel (≤ 35 HRC) | 57.0 | 0.111 | 1993 |
| Stainless Steel (304/316) | 49.7 | 0.105 | 1738 |
| Cast Iron (GG/GGG) | 73.8 | 0.135 | 2581 |
| Aluminum Alloy (Wrought) | 102.8 | 0.16 | 3595 |
| Titanium Alloy (Ti-6Al-4V) | 34.8 | 0.092 | 1217 |
Operating Guidelines
- Runout Check: Verify spindle runout is ≤ 0.01 mm at the tool tip. Excessive runout accelerates corner wear and degrades hole tolerance.
- Peck Cycle: For depths exceeding 2.5×Dc, implement a peck drilling cycle with retract to 0.5×Dc above the bottom of the previous peck.
- Coolant Strategy: Deliver coolant through the tool when possible (internal coolant) at a minimum pressure of 20 bar for holes deeper than 2×Dc.
- Entry Angle: When drilling into inclined surfaces, use a spot drill or chamfer mill to create a 90° entry surface. Alternatively, reduce feed to 30% for the first 0.5 mm.
- Tool Life Monitoring: Monitor flank wear (VB). Regrind or replace when VB reaches 0.3 mm for steels, or 0.2 mm for stainless and titanium.
- Chip Inspection: Ideal chips should be short, curled C-shapes or 6-shapes. Long stringy chips indicate insufficient feed or inadequate coolant.
- Storage: Store in original packaging away from vibration and humidity. Carbide is brittle; avoid contact with other tools.
Toolholder Compatibility
The 9.1mm cylindrical shank is compatible with the following clamping systems and collet types:
| Holder Type | Collet / Chuck Size | Runout Capability | Best For |
|---|---|---|---|
| Hydraulic Expansion Chuck | 9.1 mm (or next standard) | ≤ 0.003 mm | High-precision finishing; tight tolerances |
| ER Collet Chuck (ER16/ER20/ER25) | ER16 (9.1 mm) | ≤ 0.01 mm | General machining; good versatility |
| Shrink Fit Chuck | 9.1 mm H5 | ≤ 0.003 mm | High-speed machining; maximum rigidity |
| Milling Chuck (Power Chuck) | 9.1 mm | ≤ 0.008 mm | Heavy-duty roughing; high torque |
| Drill Chuck (Keyless) | 0.5–9.1 mm capacity | ≤ 0.05 mm | Manual operations; non-critical tolerances |
