Collection: Power Tools

Power tools for sanding, grinding and polishing are the machines that plug in or run on batteries, as opposed to pneumatic tools. The catalogue has 24 of them, from finish sanding to heavy grinding.

Families in the catalogue

• Orbital sanders: Mirka DEROS II range, Dynabrade NITRO. See our electric orbital sanders.
• Belt sanders: FEIN GRIT GKS 75 and GILS.
• Grinders: FEIN CCG 18-125-12 AS angle grinder, AGSZ 18-280 LBL AS straight grinder, Dynabrade electric. See our electric grinders.
• Polishers: Dynabrade NITRO RB4, DB8E, ROB2, FLEX PXE 80. See our electric polishers.
• Drilling and screwdriving: FEIN ASCM 18-4 QM AS and ASCM 18 QMP AS.

Electric or pneumatic, the real trade-off

Electric delivers constant torque without depending on an air network, and plugs in anywhere. It needs no sized compressor, dryer or drain.

Pneumatic remains lighter for the same power and does not overheat in continuous use. At a workstation held by hand all day, this is measured in fatigue.

The deciding criterion is often infrastructure: a workshop without a correctly sized air network will run its pneumatic tools below their performance, with no breakdown and no visible sign.

Cordless: the trap of stated run time

The run time of a cordless machine is measured at reduced speed and without load. Under real pressure it often falls by half.

The right criterion is not the stated run time but the number of batteries available, the charging time and above all platform compatibility. Multiplying brands means multiplying chargers and tying up capital in batteries that only serve one machine.

Variable speed is not a comfort extra

Each abrasive has an optimum speed range, expressed at the periphery. Too slow it rubs, too fast it heats and wears. As this speed depends on the diameter of the tool fitted, a fixed-speed machine can only be right for one diameter.

On aluminium and plastics, which load and melt at high speed, being able to slow down changes the result more than any change of abrasive.
