CAT50 angle heads for machining centres

Every angle head Mongtec publishes in the BT50 class can be built on a CAT50 V-flange shank instead. The 7/24 taper is the same; the flange form and the pull stud (retention knob) thread are what change. 74 models are listed below. Mongtec Precision is a Taiwanese brand, designed and engineered in Taichung, Taiwan.

Pull stud — the part that is easy to get wrong

A CAT40 spindle and a BT40 spindle share the 7/24 taper, so the head goes in — but the pull stud thread does not carry over. CAT tooling in North America is commonly 5/8-11, while BT40 is M16. If the retention knob is wrong the head will not clamp, and that is the single most common reason an angle head arrives and cannot be used. Send the spindle type and the retention knob drawing or part number with the enquiry and Mongtec confirms it before quoting.

Custom angle heads and drawing conversion

Every model in this range can be built to order. Reach, head profile, output interface, angle, coolant and the stop arrangement are matched to the operation and the machine.
