High-Performance Indexable Drilling Solutions for CNC Excellence
Maximize your hole-making efficiency with our 2026 collection of indexable drills and U drills. Engineered for high-speed stability and superior chip evacuation, our drilling tools are designed to handle the most demanding CNC drilling operations, from shallow holes to deep-hole processing.
Precision U Drills & Fast Drills
Our drilling range features high-rigidity tool bodies that minimize deflection and ensure high dimensional accuracy. By utilizing replaceable carbide inserts (such as WCMX, SPMG, and WCMT series), our tools offer a cost-effective alternative to solid carbide drills, especially in large-diameter applications.
Key Technical Advantages
- Optimal Chip Evacuation: Optimized flute geometry with internal coolant channels ensures smooth chip removal and prevents heat buildup.
- Versatile Range: Available in 2xD, 3xD, 4xD, and 5xD drilling depths, covering diameters from φ12mm to φ60mm.
- Multi-Material Application: Expertly machines Steel (P), Stainless Steel (M), Cast Iron (K), and Aluminum (N).
- Durability: Nickel-plated tool bodies provide excellent wear resistance and prevent corrosion during long-term use.
*Technical Note: We support a vast array of indexable drilling specifications. If the specific diameter or depth you require is not shown in the gallery, please contact our technical team for immediate selection support.*

FREQUENTLY ASKED QUESTIONS AND ANSWERS
Q: What are the advantages of using indexable U drills over solid carbide drills?
A: Indexable drills are significantly more cost-effective for larger diameters (usually >φ12mm). They offer higher flexibility—you only need to replace the carbide inserts (like WCMX or SPMG) rather than the entire tool, which drastically reduces your tooling cost per hole.
Q: Do your U drills support internal cooling?
A: Yes. All our indexable drills come standard with internal coolant holes. This is essential for effective chip evacuation and cooling the cutting edge, especially when drilling 3xD, 4xD, or 5xD depths.
Q: Can your drilling tools be used on both CNC lathes and milling machines?
A: Absolutely. Our drills are designed for both rotating and stationary applications. They feature standard shanks (like Side-lock/Weldon shanks) that can be easily mounted on CNC machining centers or CNC lathes.
Q4: Which insert grades should I use for machining stainless steel?
A: For stainless steel (M), we recommend our specific PVD-coated carbide inserts with sharp chip-breakers. When you send an inquiry, please specify your material, and our engineers will recommend the exact insert grade to optimize tool life.
Q5: What is the maximum drilling depth you can provide?
A: Our standard stock includes 2xD, 3xD, 4xD, and 5xD depths. For deeper hole requirements or non-standard diameters, we can provide customized tool body solutions to meet your specific machining challenges.
