For shop fabrication, both the Bosch GWS13-50 and Metabo WEV15-125 are serious 5-inch angle grinders, but they are aimed at different work habits. The Bosch is a straightforward, high-speed 13-amp grinder for cutting, grinding, and flap-disc work. The Metabo adds variable speed and more electronic protection, which matters when you use wire wheels, sanding discs, … Read more
Weld spatter is usually best removed with a flap disc or a hard grinding disc, not a cutoff wheel. The right choice depends on whether you need to preserve the surrounding surface, how much spatter there is, and what the workpiece is made of. A disc that is too aggressive can gouge the parent metal; … Read more
For most steel roofing work, a metal-cutting circular saw is the better tool for making long, straight cuts. It is faster, easier to guide along a marked line, and—when fitted with a blade made for ferrous metal—usually leaves a cleaner edge than an angle grinder. An angle grinder costs less, handles short notches and awkward … Read more
The short answer For cutting conduit, the Milwaukee M18 FUEL metal saw is usually the cleaner, faster choice—especially for repeated cuts in EMT. Its larger blade and metal-cutting design suit the job. The DeWalt DCS373 is a compact 5-1/2-inch metal-cutting circular saw that can make neat cuts too, but its smaller blade and less forgiving … Read more
The short answer For occasional cuts on a jobsite, a cordless angle grinder is usually the easier tool to use. It needs no outlet or extension cord, and cutting a few pieces of rebar is well within the reach of a modern 4½- or 5-inch grinder. For repeated cuts, long sessions, or the lowest upfront … Read more
Quick answer For removing grout between floor tiles, start with a carbide-grit oscillating grout-removal blade sized to fit the grout joint. It is usually the best balance of cutting speed, cost and control for ordinary cement-based grout. Choose a diamond-grit blade instead if the grout is especially hard, you expect to work on several joints, … Read more
What you need from a guard Switching an angle grinder between grinding and cutting is not a reason to run without a guard. It is a reason to use a guard designed for the wheel and operation, and to check that it can be repositioned securely. A grinding guard is deeper and covers more of … Read more
For metal cleanup, the Milwaukee M18 FUEL grinder and Makita XAG26 are both capable 4½-inch cordless angle grinders. They can remove weld spatter, clean edges and cut steel, but their controls and handling differ enough to matter when you’re working for more than a few minutes. The right pick depends less on peak power than … Read more
Flush cutting with a reciprocating saw means cutting as close as possible to a fixed surface, such as trimming a pipe against a wall, cutting off protruding nails, or removing a door jamb without damaging nearby material. Blade length matters, but the longest blade is rarely the best choice. The right length gives you enough … Read more
Why flush cuts scar the surface A flush cut removes a protruding nail, shim, dowel, or piece of trim level with a finished surface. The risk is that the blade teeth—or the blade’s side—rub against the work and leave scratches, burn marks, or a shallow gouge. Oscillating tools are useful here because their short, controlled … Read more
