Magnetic drilling machines and accessories

The magnetic drilling machine is carried to the workpiece, not the other way round. You attach it with the electromagnet to the beam, the column or the sheet and drill holes up to 50 mm with a core drill — horizontally, vertically and overhead. At Promash there are 17 Optimum and Metallkraft magnetic drilling machines with prices from €679 to €1,678.80, all for 230 V.

What types of magnetic drilling machines are there?

Magnetic drilling machines are divided by the maximum diameter with a core drill — with us 35, 38 and 50 mm — by power and by weight. All have an electromagnetic base and run on 230 V, and on most models the speed is adjustable, for example from 100 to 800 rpm on the Metallkraft MB 351 BL-V.

Compact models up to 35–38 mm

The OPTIdrill DM 35 V, DM 38 VF and Metallkraft MB 351 BL-V are for installers and welders who carry the machine around the site. The DM 35 V weighs 10.8 kg, drills with a core drill up to Ø35 mm and with a drill bit up to Ø13 mm, and the magnet holds with 14.8 kN.

Powerful models up to 50 mm

The DM 50 V, DM 50 PM and Metallkraft MB 502 BL-V work with core drills up to Ø50 mm. The DM 50 V weighs about 11 kg and holds with 15.6 kN. The DM 50 PM has a 1.7 kW motor, a magnetic force of 16.5 kN, a 3/4″ Weldon holder and a drilling depth of 50 mm — for thick flat bars and beams.

How to choose a magnetic drilling machine?

Choose according to the largest hole you will make and the thickness of the material. For holes up to 35 mm in profiles and flat bars a compact model at €679–701 is sufficient. For Ø40–50 mm and thick metal take a machine of the 50 mm class, so as not to work at the limit of its capabilities.

• Diameter with a core drill. 35 mm (DM 35 V, DM 35 PF, MB 351 BL-V), 38 mm (DM 38 VF), 50 mm (DM 50 V, DM 50 PM, MB 502 BL-V).
• Power. All models are between 1.55 and 1.75 kW and run on 230 V — you plug them into an ordinary socket or a generator on site.
• Speed. Adjustable speed helps when you change core drills from small to large and work with stainless steel.
• Weight and magnet. A lighter machine is easier to carry up a ladder, a stronger magnet holds more securely on thin material.

Core drills and drill bits are replaced more often than the machine. You will find HSS TiAlN core drill sets and other consumables in the drilling accessories.

Comparison of popular models

All seven models run on 230 V. The differences are in power, in maximum diameter and in price — the table shows the five we are asked about most often.

What is a magnetic drilling machine used for?

The magnetic drilling machine is the tool of the metal structure installer. It is used when erecting halls and canopies, in shipbuilding, in the repair of bridges and machines — wherever the workpiece is too large or already installed and cannot go under a pillar drilling machine.

A core drill cuts only a ring out of the metal, so the hole is made quickly and with less effort than with a twist drill of the same diameter. When the workpieces are small and come to the machine, the pillar drilling machine is more convenient.
