What is an Indexable Drill?
An indexable drill — also called an indexable insert drill or replaceable tip drill — is a high-performance drilling tool designed for CNC machining centers and turning centers. It features a reusable drill body and replaceable inserts, allowing users to replace only the worn cutting edges instead of the entire tool.
We offer a complete selection, from indexable drill bits for general drilling to flat bottom indexable drills, modular drill, and other specialized types, covering a wide range of machining needs.

Why Choose Our Indexable Drill bits
Our Indexable Drills are engineered for precision, durability, and cost-efficiency, making them the preferred choice for CNC machining centers and turning centers. As a reliable alternative to major brands like Iscar indexable drills, Ingersoll indexable drills, Komet indexable drills, and Mitsubishi indexable drills, they deliver comparable performance while providing significant savings.
Significant Cost Savings
With our Indexable drills, you can reduce tooling costs by up to 50% without compromising performance. By replacing only the indexable drill inserts instead of the entire indexable drill body, manufacturers have achieved measurable cost reductions and productivity gains. We have delivered quantified savings and efficiency improvements for over 100 global customers in industries ranging from automotive to heavy machinery.
World-Class Products
Our product range combines the reliability of global brands with the value of a trusted Chinese alternative, helping customers achieve the highest cost-performance ratio. From technical selection to after-sales support, we provide end-to-end service for large-scale clients, ensuring every step — from choosing the right indexable u drill or adjustable indexable drill to setting the correct feeds and speeds — meets your production demands.
Whether you need a flat bottom indexable drill for counterboring, an indexable core drill for enlarging pre-drilled holes, or a spot drill for precision hole positioning, our solutions offer the perfect balance between performance and cost.

High Efficiency & Productivity
From indexable u drills for high-feed drilling to flat bottom indexable drills for counterboring, our tools enable faster cycle times, better chip evacuation, and higher throughput.
Integrated One-Stop Sourcing
Beyond indexable insert drills, we supply complete CNC tooling solutions — milling cutters, turning tools, and measuring instruments — helping you reduce supplier management costs.
Precision & Stability
Optimized cutting edge geometry and rigid clamping systems ensure high concentricity, accurate hole dimensions, and longer insert life — whether you're using an indexable spot drill or an indexable core drill.
Brand-Compatible Alternative
A cost-effective solution that matches the performance of Iscar indexable drills, Ingersoll indexable drills, Komet indexable drills, and Mitsubishi indexable drills, while offering shorter lead times and better value.
Flexible Options & Customization
We offer a complete range of designs, including adjustable indexable drills for variable hole sizes and indexable drill boring bars for combined drilling and boring operations. Custom lengths, coatings, and insert grades are available upon request.
Proper maintenance of your indexable drill ensures maximum performance and longevity. To keep your tool in top condition, start by regularly inspecting the inserts for signs of wear or damage. Replacing worn inserts promptly prevents unnecessary damage to the drill body and maintains cutting efficiency. Next, make sure to clean the drill after each use to remove debris, cutting fluids, and chips. Keeping the drill clean helps avoid clogging and overheating, which can impact cutting performance. Lubricate the tool with the appropriate cutting fluid or oil to minimize friction and heat generation during use, ensuring smooth operation and preventing premature wear. Lastly, store the indexable drill in a dry, clean environment to prevent rust or corrosion. Using a protective case or tool holder can prevent physical damage when not in use. By following these simple maintenance steps, you can extend the life of your indexable drills, reduce downtime, and maintain consistent hole quality in your machining operations.
FAQ
What is an Indexable Drill and how does it work?
+
-
An indexable drill is a cutting tool with replaceable carbide inserts mounted on a drill body. Instead of regrinding the entire tool, you replace the worn inserts, reducing downtime and cost. It works by using the inserts to cut material in a balanced way, ensuring stability and consistent hole size.
What is the ideal drilling depth for indexable drills?
+
-
Most indexable drills are designed for depths up to 5xD (five times the diameter), though some specialized designs can go deeper. Always follow the manufacturer’s recommendations.
What hole sizes can indexable drills achieve?
+
-
They are typically available in diameters from 12 mm to over 100 mm, depending on the drill body design. Custom solutions are available for special sizes.
What are the main advantages of indexable drills?
+
-
Key advantages include quick insert replacement, reduced tool cost over time, high productivity, and the ability to maintain consistent hole quality without frequent regrinding.
How do indexable drills compare to solid carbide drills?
+
-
Indexable drills are more economical for larger diameters and high-volume production due to replaceable inserts, while solid carbide drills offer higher precision for small diameters and deep holes.
