Husqvarna Core Drills

The Husqvarna drilling range — what DM, DS and DMS stand for

Husqvarna sorts its drilling equipment with three symbols. DM stands for Drill Motor: gearbox and bit spindle, guided by hand or on a column carriage. DS stands for Drill Stand — base, feed mechanism and anchoring hardware. DMS is a factory-matched motor-and-stand set.

Motors here take bits on the 1 1/4" UNC thread, so tooling swaps freely between models and brands. Bits, extensions, water collection rings and the VP 200 vacuum pump sit under diamond core drill bits and core drill accessories.

Matching a Husqvarna core drill to the hole you need

Bit diameter drives the choice. Openings for pipes and cables are hand-held work; through-holes in load-bearing walls, slabs and foundations need a rig-mounted motor, since only a rigid column holds the axis steady under the torque of a large bit.

This page holds the DMS 240 set, the DM 400 rig motor, the hydraulic DM 406 H and DS stands from the DS 150 and DS 40 Gyro up to the DS 500 and DS 900, each picked to suit the motor it carries. The rest of the brand's line-up sits across core drill motors, core drill stands, hand-held core drills and complete core drills.

Wet drilling, anchoring the stand and motor protection

Husqvarna core drills are built for wet work. Water fed through the spindle cools the diamond segments and flushes slurry out of the kerf; a few litres per minute extends bit life and keeps the barrel from binding. On floors the run-off is caught by a collection ring connected to a slurry vacuum. The stand base is fixed with an expansion anchor or a jack braced against the ceiling, or, on smooth non-porous surfaces, by vacuum. Overload electronics, branded Elgard, cut power before a jammed bit damages the motor. With no site supply, the machines run off power packs and generators.
