Product Overview
The Kyocera SGM07071 is a micro-sized solid carbide drill featuring a 0.15 mm cutting diameter and 2-flute design. Engineered with TA grade substrate and advanced PVD coating technology, this drill delivers exceptional dimensional accuracy, superior surface finish, and extended tool life in demanding CNC machining environments. The optimized helix and point geometry ensure efficient chip evacuation even in deep-hole applications up to 3×D to 5×D.

Chipbreaker Profile
The SGM07071 utilizes a proprietary TA-optimized micro-geometry with enhanced edge prep designed specifically for 0.15 mm diameter drilling. The edge preparation features a micro-honed land of 0.01–0.02 mm at 20°–25°, combined with a polished rake face (Ra 0.05 μm) to minimize built-up edge and adhesion when machining sticky materials such as stainless steel or titanium.
| Chipbreaker Parameter | Value | Function |
|---|---|---|
| Edge Preparation | Micro-hone 0.01–0.02 mm | Prevents chipping on entry |
| Rake Face Finish | Ra ≤ 0.05 μm | Reduces adhesion and BUE |
| Flute Polishing | Ra ≤ 0.08 μm | Enhances chip evacuation |
| Margin Width | 0.08×D | Stabilizes drill in hole |
Recommended Applications & Workpiece Materials
This drill is optimized for the following material groups and industrial sectors:
- General Engineering: Structural steels, free-cutting steels, and low-alloy steels (≤ 900 MPa tensile strength)
- Automotive: Crankshafts, camshafts, gearbox components, and hydraulic valve bodies
- Aerospace: Titanium alloy fasteners, aluminum structural brackets, and Inconel heat shields
- Medical: Stainless steel 316L surgical instruments and implant-grade titanium
- Mold & Die: Hardened tool steel (P20, H13) up to 52 HRC with TA grade
- Electronics: Copper and aluminum micro-holes for heat sinks and connectors
Application Map by Operation
| Operation Type | Suitability | Max Depth | Remarks |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ | 3×D | Excellent chip break and evacuation |
| Blind-Hole Drilling | ★★★★☆ | 2.5×D | Use peck cycle for deep blind holes |
| Center Drilling | ★★★★★ | 1×D | Self-centering 140° point angle |
| Spot Drilling | ★★★★☆ | 0.5×D | Reduced feed for accurate spotting |
| Enlarging / Reaming | ★★☆☆☆ | Not recommended | Not designed for enlarging operations |
| Cross-Hole Drilling | ★★★☆☆ | 1.5×D | Reduce feed by 30% at intersection |
Recommended Cutting Conditions
The following parameters are starting recommendations. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing.
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant Strategy |
|---|---|---|---|
| Hardened Steel (50-55 HRC) | 40-80 | 0.01-0.04 | External |
| Titanium Alloy (Ti-6Al-4V) | 50-90 | 0.01-0.05 | Flood / High-pressure |
| Stainless Steel (304/316) | 80-120 | 0.015-0.06 | External / Through-spindle |
| Carbon Steel (≤ 45 HRC) | 120-180 | 0.02-0.08 | External / MQL |
• 1st peck: 1.0×D depth, 50% retract
• 2nd peck: 0.7×D depth, 50% retract
• Subsequent pecks: 0.3×D depth, full retract to clear chips
• Reduce feed by 20% below 1×D depth to stabilize drill
Operating Guidelines
- Runout Tolerance: Maximum tool runout at the cutting lip should not exceed 0.01 mm (4 μm per lip). Use precision collets or shrink-fit holders.
- Coolant Pressure: For through-tool coolant, maintain 20–70 bar (300–1000 psi) pressure. For external coolant, use high-volume flood with 5–8% concentration emulsion.
- Entry Surface: Ensure the entry surface is flat and perpendicular to the drill axis. Chamfer or spot-drill inclined surfaces before drilling.
- Pre-Hole: For diameters ≤ 0.5 mm, a center drill or spot drill of 90°–120° is recommended to prevent wandering.
- Speed & Feed Ramp: Ramp spindle speed over 2–3 seconds to avoid thermal shock. Reduce feed by 50% for the first 0.5 mm of engagement.
- Tool Life Check: Monitor hole diameter and surface finish. Re-sharpen or replace when hole tolerance exceeds IT9 or surface roughness exceeds Ra 1.6 μm.
- Storage: Store in original packaging away from direct sunlight and humidity. Avoid contact between cutting edges and hard surfaces.
Toolholder Compatibility
| Holder Type | Recommended Series | Max Runout | Notes |
|---|---|---|---|
| Spring Collet | ER11/ER16 Collet | ≤ 10 μm | Most economical for general use |
| Precision Collet | SK10/SK16 Collet | ≤ 5 μm | Recommended for micro-drills ≤ 1 mm |
| Hydraulic Chuck | Hydraulic Chuck HSK-E32 | ≤ 3 μm | Best damping for tough materials |
| Shrink Fit | Shrink Fit HSK-E32 | ≤ 3 μm | Excellent for high-speed machining |
