❓ Frequently Asked Questions (FAQ)

1. What are the main features of the 31mm Two Pipe Deep Hole Ejector Drill?

This drill head features a robust structure made of Aviation pre-hardened material. It offers high efficiency, low operational costs, a short lead time, and easy installation with high-quality alloy steel body design.

2. How does the double-tube ejector system work compared to single-tube systems?

The double-tube (two pipe) ejector system delivers coolant via the space between the outer and inner tubes. Chips and coolant are then suctioned back out through the inner tube, preventing chip clogging and providing cleaner drilling processing.

3. What kind of inserts and guide pads are compatible with this BTA drill head?

It utilizes super-coated carbide inserts (including central, intermediate, and peripheral types) and solid carbide guide pads designed to enhance drilling accuracy and prolong tool lifespan.

4. Can this ejector drill be used for machining hard or specialty alloys?

Yes. Thanks to the aviation pre-hardened tool body and super-coated carbide inserts, this drill head is widely designed for machining different tough workpieces and materials efficiently.

5. What sizes are available for the DTS BTA drilling head range?

The product parameters catalog lists dimensions ranging from 25mm to 65mm. Standard configurations for central, intermediate, and peripheral inserts correspond directly to the specific size brackets required.
