Harbor Freight Tools has several models for different applications, from carving wood to cutting metal.
Answering the following questions should help you decide on the best tool for the job.
- How often will the tool be used? If the tool will be used daily, then you should consider a more
powerful rotary tool.
- What will the tool be used for? If your application will mostly involve precision work like carving and
engraving, then consider a tool with a flexible shaft and a handpiece. The handpiece offers more control
when detailing. If your application will mostly involve cutting metal like bolts, all-thread rod, or
thin metal sheet, then consider a more powerful tool with speed control.
The Warrior 12V Cordless Variable-Speed Rotary Tool is a medium duty, general application tool. It will cut
metal and can also be used for precision carving, engraving, sharpening, and polishing. Because this Rotary Tool
is cordless, it offers portability and flexibility. This tool uses the same battery pack as other Warrior 12V
cordless tools.
There are many types of bits supplied with the tools. Refer to the manual and the included bit/material/speed
chart.
- High-speed cutting bits: intended for cutting and carving wood, plastic, and soft metal
- Tungsten carbide cutters: intended for engraving hard materials
- Grinding stones, Aluminum oxide (red or orange): intended for general purpose grinding and sharpening
- Grinding stones, Silicon carbide (blue or green): intended for griding hard materials like glass and
fired ceramic
- Diamond coated bits: intended for carving and engraving wood as well as hard materials like ceramic,
stone, and glass
- Wire brushes: intended for conditioning metals like rust removal
- Nylon brushes: intended for detail cleaning
- Polishing wheels and bobs: intended to be used with polishing compounds to polish metals and plastics
- Sanding bands: intended for detail sanding of wood, metal and plastics
- Cutting discs: intended for cutting off metal or plastic materials
When using the tool, make sure that the vents are not covered because covering the vents will impede airflow and
cause the housing to build up heat. Also, if the tool is used continuously, it may start to feel warm. To lower
the tool temperature, turn off the tool and let it cool or run the tool without load and without a bit for about
a minute to circulate air through the motor. When working on a workpiece, always let the tool do the work
instead of pushing hard on the material, which can stress the tool.
Let the tool do the work. Adding pressure and pressing hard on the workpiece is not necessary and may decrease
the speed of the bit. If the tool stops, either decrease the force being applied until the bit spins faster or
turn it back on and apply less force to the workpiece. If reducing the pressure on the tool does not work, the
tool may not have enough power for your application. Please make sure you use the proper tool based on the needs
of your application.
