Can a grinder replace a wall chaser?

It can, but the result differs: depth varies, the machine has to make two passes for two parallel cuts, and dust spreads uncontrolled. A chaser runs twin discs at fixed width with extraction at source.

Which figure matters on a mortar mixer?

Torque at low speed, and the speed control. Watts alone say little; a machine that cannot make torque at low speed will labour and overheat in dense mixes.

Can I mix mortar with a drill?

In small volumes yes, but a drill's gearbox is not built for continuous high torque. For regular work use a proper mixer.

Where are pipe press tools used?

On press-fit systems: steel, stainless and multilayer pipe, where a calibrated jaw compresses a sealed fitting into a leak-tight joint. Jaw profile is chosen to match the pipe system.

Is a heat gun the same as a torch?

No. A heat gun is flameless with stepped temperature control, used for stripping paint, forming plastic and shrinking sleeving. A torch produces much higher temperatures with an open flame.

Specialty Power Tools

Specialty tools exist to do quickly and cleanly what a general-purpose machine only manages under strain: chasing a services channel in a wall, mixing mortar, making a press-fit joint or cutting rebar. This page covers the main machines in the group and what each replaces. The catalogue holds 95 models.

The machines in this group

What these share is being built to do one job repeatedly and fast. The same work can be done with a grinder or a drill, but the difference in time, finish and dust control is large.

Machine	Job	Versus the alternative
Wall chaser	Services channels in masonry	Twin discs, fixed depth, dust extraction
Mortar mixer	Mortar, paint, plaster	High torque at low speed
Pipe press tool	Press-fit joints	Calibrated jaws, repeatable force
Rebar/wire cutter	Cutting reinforcement bar	No sparks, fast square cut
Heat gun	Stripping paint, forming	Controlled temperature steps

Wall chasers

A wall chaser runs two parallel diamond discs to cut two lines of fixed width and depth; the material between them is knocked out with a chisel. Unlike a channel opened with a single-disc grinder, the depth stays constant and the chase comes out straight.

Dust extraction is not an extra here but basic equipment: dry cutting releases respirable silica dust, and extraction collects most of it at source.

Mortar mixers

The figure that matters is not speed but torque at low speed. Plaster and paint need only a single-paddle, low-viscosity machine; screed, mortar and adhesives call for twin paddles and high torque.

Paddle geometry follows the mix too: an up-lifting paddle for dense mortar without whipping air in, a down-drawing one for paint and liquid mixes.
