Frequently Asked Questions
What can the HM 12 P process?
It creates rectangular mortises for tenon-mortise joints on solid wood, plywood, and wood-based panels.
Bernardo HM square chisel mortisers allow for the direct creation of right-angle mortises, without the need for manual finishing. Typical applications: door and window frames, chairs, furniture, and structural assemblies.
What chisel sizes does it support?
Typically chisels from 6 to 25 mm in width. Check the technical table for "drilling capacity" or "mortising capacity".
Bernardo HM chisels are dedicated accessories with a cylindrical shank and a hardened hollow tip. Krollit supplies original spare parts compatible with the HM 12, HM 25, and HM 30 series.
Is the head tiltable or rotatable?
It depends on the model: HM 25 has a 180° rotatable head, HM 25 TOP has a tiltable head ±22.5° right/left.
The rotatable head allows working on large pieces such as doors and frames from the back. The tiltable head allows for angled mortises for mitered assemblies.
What power supply does it require?
Models HM 12, HM 25, and HM 30 are equipped with a 0.75 kW single-phase 230 V motor. See "Voltage" in the technical table.
The single-phase power supply makes these mortisers usable even in workshops without a three-phase line. The machine still requires dedicated residual current protection.
How much does the machine weigh?
See the "Weight" data in the technical table. Typically 100 kg (HM 25) or 110 kg (HM 25 TOP).
The high cast iron mass provides rigidity during mortising, reducing vibrations and improving precision. For handling and installation, a hydraulic trolley or the help of a second operator is recommended.
