If you work in a trade or even for domestic DIY use, you are likely going to need to buy tools; there are so many companies that offer tool to buy that it can be slightly overwhelming to find the right one. If you are looking for a shop I recommend just staying local as there really wont be too much difference in stores, if you are looking online I would however recommend looking around as prices and products can vary greatly between online shops and because most companies deliver world wide you have a wide range of options.
Due to the magnitude of available tools I am going to list some of the most common and regularly used by tradesmen and DIY users:
Drills – Power, Cordless and Bench are the most common ones purchased you also have a range of drill bits available: HSS, Masonry, Diamond Core and Wood.
Fixing Tools – Glue Guns, Staple Nailers / Tackers
General Tools – Angle Grinders, Bench Grinders, Multitools and Cordless Screwdrivers.
Saws – Band / Fret, Circular, Jigsaw, Mitre, table, specialist and cutting discs.
Wood Working – Biscuit Jointers, Power Planers, Routers, Sanders, Sanding Sheets and Woodturning.
Workshop Tools – Air Compressors, Spray Guns, Air Brushes, Dust Extractors and Transformers.
Miscellaneous – Water Pumps, Extension Reels / Sockets and Submersible Pumps.
As you can imagine there are a lot more different tools available and a lot of different stores that offer them, if you are looking to Buy Tools and have a specific one in mind, there are a lot of companies that specialise in certain tools, they may have more variations of the one you are looking for.
