What is an Indexable Flathead Drill?
An Indexable Flathead Drill is a replaceable-insert flathead drill designed for high-precision drilling of various materials. Its replaceable inserts reduce tool wear and improve machining efficiency, making it particularly suitable for complex parts and demanding projects. It can precisely machine holes in metals, plastics, and composites while maintaining extremely high dimensional stability.
Key Features
Efficient Drilling: Suitable for medium to high hardness materials.
Replaceable Insert Design: Reduces replacement costs and extends tool life.
Precision Positioning: Ensures hole diameter accuracy and hole wall finish.
Versatile Adaptability: Suitable for milling, drilling, thread pre-machining, and more.
By using our Wangdefu Indexable Flathead Drill, customers can significantly improve productivity, reduce downtime, and ensure high precision and consistency in every hole.
Core Technical Advantages
Indexable Inserts + Rigid Tool Body: Cost-Effective Precision You Can Trust
At Wangdefu, we design our Indexable Flathead Drill to combine economy with top-notch rigidity. Using 4-corner indexable inserts, our tools allow both peripheral and central cutting edges to share the same insert—cutting tool costs by over 40% without compromising performance. Our inserts come in premium carbide or CBN materials with advanced TiAlN/MEGACOAT NANO coating (hardness 35 GPa, oxidation resistance up to 1150°C), delivering up to 2× higher wear resistance than traditional inserts.
The tool bodies are crafted from high-strength alloy steel or solid sintered carbide, offering 2.5× more rigidity than conventional steel tools. This means even for deep-to-diameter ratios (L/D) suitable for 2D–3D specifications with long overhangs, you get minimal deflection and vibration—perfect for consistent, precise machining.
Flat-End Geometry + Optimized Cutting for Perfect Results
Our flat-end geometry is designed with a 180° cutting edge and specialized arc honing to ensure perfectly flat hole bottoms with deviation under 0.01mm. The sharp tip features a positive rake angle, reducing cutting resistance by 30% and minimizing burrs (≤0.037mm).
Thanks to our innovative chip breaker design, chips are short and easy to evacuate—even in blind or semi-through holes. This means less downtime, smoother operation, and higher productivity for your production line.
Multi-Operation Integration: Simplify Your Workflow
We understand that efficiency matters. With Wangdefu indexable insert + rigid tool body solutions, no pre-drilling is required. One tool handles:
Inclined surfaces
Cylindrical surfaces
Intersecting holes, including 3° draft surfaces
Indexable Flathead Drill also supports drilling, countersinking, and internal end-face finishing—reducing traditional six-step processes down to three. This integration can cut cutting cycle times by up to 50%, saving you both time and cost. Our tools are fully compatible with horizontal machining centers, automatic lathes, and standard holders like BT/HSK.
Precision & Stability for Batch Production
Every rigid tool body is paired with a wedge-type insert clamping system featuring eccentric pin adjustment, ensuring cutting edge runout ≤0.01mm. Diameter tolerance remains stable within ±0.03mm, while unequal pitch and low-resistance tip reduce vibration.
The result? Exceptional surface finish (Ra1.6–3.2μm) and diameter deviation <0.02mm even after 500 holes. This level of precision ensures consistent batch production—ideal for automotive, aerospace, electronics, and mold manufacturing.

Typical Applications of Wangdefu Indexable Flathead Drill
At Wangdefu, our indexable flathead drill solutions are engineered for high precision, stability, and efficiency across multiple industries. Here are some typical applications where our tools shine:
Automotive Manufacturing
For tasks like transmission housing bolt countersinking (M10–M27), our φ20mm indexable flathead drill provides exceptional performance. With a cutting speed of 150 m/min and feed rate of 0.1 mm/rev, a single tool can machine up to 3,520 holes. Compared to conventional replaceable drills, our solution improves efficiency by 50%, while maintaining consistent hole quality and burr-free finishes.
Mold Industry
When machining SKD11 mold steel inclined bolt holes with a 3° draft, our tools integrate drilling and countersinking in one step. The precise flat-end geometry ensures burr-free flat hole bottoms, completely eliminating the need for post-grinding and improving workflow efficiency.
Machinery Equipment
Large structural rib semi-through holes often require tools with excellent rigidity. Our indexable flathead drill features a robust tool body capable of long overhangs, combined with an optimized chip breaker that prevents clogging. This allows machining efficiency to increase by up to 60% compared to conventional methods, while maintaining tight tolerances and minimal tool wear.
Aerospace
For aluminum alloy housing internal end-face finishing, the flat-end geometry ensures perfect planarity. Coupled with our low-friction coating, the tools minimize workpiece damage and achieve superior surface finishes down to Ra1.6μm, meeting the high precision standards of the aerospace sector.
