Bosch Professional (blue) power tools are a favourite with Kenyan builders, fundis and workshops. Bosch model codes can be confusing, though: what is the difference between a GSR and a GSB, or a GWS 700 and a GWS 2200? This Bosch power tools buying guide explains the codes and lists prices on Buy More Mall.
| Code | Tool | Use it for |
|---|---|---|
| GSR | Drill driver | Drilling wood and metal, driving screws |
| GSB | Impact (hammer) drill | Everything a GSR does, plus drilling into brick and block |
| GDR / GDX | Impact driver | Driving long screws and bolts fast |
| GDS | Impact wrench | Nuts and bolts: vehicles, steel structures |
| GBH | Rotary hammer (SDS) | Drilling concrete, light chiselling |
| GSH | Demolition hammer | Breaking concrete and tiles |
| GWS | Angle grinder | Cutting and grinding metal, tile and stone |
| GST / GKS / GCO | Jigsaw / circular saw / cut-off saw | Cutting wood, boards and steel sections |
| GSS / GHO / GPO | Sander / planer / polisher | Finishing wood and polishing |
In cordless models, "LI" means lithium-ion battery, and the number (12V or 18V) is the battery voltage. 18V tools are more powerful, while 12V tools are lighter and more compact.






Tip: for general building work in Kenya (block, stone and brick), choose a GSB impact drill. For mostly wood and metal work, choose a GSR drill driver.

The number after GWS is roughly the wattage, and the last number is the disc size in millimetres (180 mm = 7", 230 mm = 9"). Small grinders are lighter for everyday cutting, and large 180 to 230 mm grinders cut deeper through steel and stone.
