[Product Overview]

The BT-MTB Morse Taper Adapter is an essential tool holder that allows CNC mills equipped with standard BT spindles to utilize Morse Taper shank tools. The MTB designation indicates that the adapter is designed to hold tools with an internal threaded hole at the end of the taper. A built-in drawbolt inside the adapter securely pulls the tool into the taper, making it ideal for holding end mills, shell mill arbors, and boring heads where axial pull-out forces are significant.

[Key Features & Advantages]

• High-Precision Runout: The inner and outer tapers are precision ground to achieve a runout (T.I.R.) of ≤ 0.005mm, ensuring accurate machining and extending the life of your cutting tools.

• Premium Material & Hardness: Constructed from high-quality 20CrMnTi steel. The surface is carbonitrided to a hardness of HRC 56-60 for excellent wear resistance, while the core remains tough to absorb cutting vibrations.

• Secure MTB Locking: Features the standard MTB internal drawbar mechanism, providing a positive lock that prevents the tool from loosening or pulling out during heavy radial cuts.

• Comprehensive Size Range: We manufacture the full spectrum of combinations, including popular sizes like BT40-MTB2, BT40-MTB3, BT40-MTB4, and heavy-duty BT50-MTB5 holders.

• Dynamic Balancing (Optional): Standard holders are suitable for general CNC use. For high-speed applications, we offer dynamic balancing to G6.3 or G2.5 at 12,000 - 25,000 RPM.

[Why Partner with Pingyuan Zhenghao Machinery?]

• Direct Manufacturer: We produce these adapters in-house, allowing us to offer highly competitive prices without middleman markups.

• Strict Quality Control: Every adapter is inspected using advanced air gauges to verify the taper contact area (≥ 85%) and concentricity before shipping.

• One-Stop Tooling Solution: We also supply the matching BT Pull Studs (Retention Knobs), MTA Adapters (for drills), and a wide variety of collet chucks.

• Customization & OEM: We can laser engrave your company logo and part numbers on the tool holders for easy inventory management and brand building.

Frequently Asked Questions (FAQ) - Selection Guide

Q1: What is the exact difference between MTA and MTB adapters?

A:

• MTA (Morse Taper with Tang): Designed for tools with a flat tang at the end (like twist drills). It relies on friction and the tang slot for driving.

• MTB (Morse Taper with Drawbar): Designed for tools with a threaded hole at the end (like milling cutters). It uses a drawbolt to pull and lock the tool securely into the taper, preventing it from falling out during milling.

Q2: Does the adapter come with the internal drawbolt?

A: Yes, all our MTB adapters come fully assembled with the internal drawbolt/screw required to secure your Morse Taper tool.

Q3: Are pull studs (retention knobs) included?

A: Pull studs are generally sold separately because different CNC machines use different pull stud standards (e.g., 45°, 60°, 90° angles). Please let us know your machine model, and we can supply the correct pull studs with your order.

Q4: Can I use coolant-through tools with this adapter?

A: Standard MTB adapters are solid. If you require Coolant-Through (AD or AD/B type) functionality for internal tool cooling, please specify this in your inquiry, as it requires a specialized manufacturing process.
