Core Product Specifications
Our Indexable flathead drill series is designed for precision, efficiency, and versatility across a wide range of materials and applications. Below are the core technical specifications for your reference:
| Parameter Type | Available Options |
| Tool Type | General-purpose flat-end drill, Long-neck type (for long overhang), Internal coolant type, Miniature tools for automated machinery |
| Tool Body Material | Submicron carbide |
| Coating Type | EgiAs coating, TiAlN coating, TiCN coating, Uncoated |
| Hole Diameter | φ0.2–φ30mm (standard), larger diameters can be customized |
| Depth-to-Diameter Ratio (L/D) | 2D (general), 3D (standard), 5D (deep hole specialized) |
| Shank Type | Straight shank, Morse taper, BT/HSK interface |
| Cooling Method | External coolant, Internal coolant (high-pressure oil holes) |
| Machining Accuracy | Hole tolerance IT8–IT10, bottom flatness <0.01mm, surface roughness Ra1.6–3.2μm |
| Suitable Materials | Carbon steel, Alloy steel, Mold steel, Stainless steel, Cast iron, Ductile iron, Aluminum alloys, Pre-hardened steel (HRC40–55), Plastic mold steel, etc. |
Typical Applications
Automobile manufacturing:
For countersunk machining of transmission housing bolts (M10-M27), our φ20mm internally cooled Indexable flathead drill performs exceptionally well. Cutting speed of 150 m/min, feed rate of 0.1 mm/revolution, a single tool can machine more than 3500 holes with flat bottom without burrs, no subsequent grinding process, significantly improve production efficiency.
Bearing industry
For 1020 steel bearing counterbore machining (1.5 - 4 inch depth), this tool can replace traditional step drilling or pecking without pre-drilling pilot holes. Machining efficiency increased by 50%, tool life more than 200 holes, counterbore surface finish high.
Mold manufacturing
For oblique bolt hole machining in SKD11 die steel (draft angle 0°-25°), our rigid tool body and precision centering design ensure accurate hole positioning. A single tool can complete drilling and countersinking at one time, reducing the processing cycle by 40%.
Precision instruments
For aluminum assembly holes (φ3-φ8mm), the uncoated design reduces adhesion and achieves a bottom flatness of 0.008 mm and a surface roughness of Ra 1.6 μm. This ensures excellent flatness and meets precision assembly requirements.
Recommended Cutting Parameters
| Material | Cutting Speed (Vc) | Feed (f) | Axial Depth (Ap) |
| 45# Carbon Steel | 80–150 m/min | 0.10–0.20 mm/rev | 5–25 mm |
| 304 Stainless Steel | 30–70 m/min | 0.03–0.08 mm/rev | 3–15 mm |
| Gray Cast Iron | 70–120 m/min | 0.09–0.15 mm/rev | 8–30 mm |
| 6061 Aluminum Alloy | 165–300 m/min | 0.14–0.20 mm/rev | 5–20 mm |
| Pre-Hardened Steel (HRC45) | 40–80 m/min | 0.05–0.10 mm/rev | 4–18 mm |
Notes:
1.For draft angles above 30°, reduce spindle speed to 70% and feed rate to 30% of standard values.
2.Reserve 1–2 mm chip evacuation space for blind holes.
3.For stainless steel or high-temperature alloys, use internal coolant type with extreme pressure cutting fluids.
