Frequently Asked Questions
Q: What is the advantage of using TOGT inserts in gun drills?
TOGT inserts provide superior chip fragmentation and allow for much higher feed rates compared to standard carbide-tipped drills, leading to increased productivity and easier chip removal.
Q: What is the difference between the DJQ and ZDJQ series?
The DJQ series (12-32mm) features a brazed shank construction, while the ZDJQ series (16-32mm) uses an integral shank design for different machine spindle requirements.
Q: Can these gun drills handle blind hole drilling?
Yes, the DJQ-ZDJQ series is specifically designed for complex machining tasks, including blind holes, stepped bores, and intersecting holes.
Q: Is regrinding necessary for these tools?
No, these are indexable tools. When the cutting edge is worn, you simply replace the TOGT insert and guide pads, eliminating the need for complex regrinding processes.
Q: Are there different grades available for different materials?
Yes, we offer various insert grades optimized for different materials, particularly focused on steel and mold-making materials to ensure maximum tool life.
Q: What is the typical production capacity for these drills?
We maintain a production capacity of approximately 5000 pieces per month to ensure steady supply for industrial requirements.
