12V SDS Hammer Drill

  • Concrete and masonry drilling — ideal for creating anchor holes, fixings, and dowels in concrete, brick, stone, and blockwork.

  • Construction and renovation work — perfect for installing conduit, pipe runs, cable channels, and general site drilling tasks.

  • Electrical and plumbing installations — efficient for drilling access points and fastening holes for mounts, brackets, clips, and fixtures.

  • HVAC installation and service — suitable for mounting units, supports, and ducting hardware into masonry surfaces.

  • Light chiselling and material removal — capable of tile removal, surface preparation, and small-scale demolition work.

  • Industrial and facility maintenance — dependable for routine drilling and fixing tasks throughout factories, warehouses, and workshops.

  • Carpentry and joinery on mixed substrates — effective when drilling into reinforced or composite surfaces where additional impact force is required.

  • General trade use — a versatile tool for builders, electricians, plumbers, maintenance crews, and multi-trade professionals needing compact SDS performance.

Tool Features

Technologies

Our patent-pending All-In-One motor includes the power, control & communication board along with the automatic winding stator with an interior permanent magnet design rotor, all enclosed in a die-cast cover. These one-unit components have several advantages, including weight reduction, longer lifespan, and crucially our number one design goal of efficiency as there are no additional components to cool.

DC motors have traditionally been driven by carbon brushes to power the motor. Over time these wear out and need replacing. All our motors are brushless meaning that the motor is controlled electronically without the need for carbon brushes ensuring your tool is maintenance-free.
