Bosch PBD 40
Powerful 1,010 W motor with electronic speed control for precise drilling.
Who is a Bosch pillar drill for?
Bosch pillar drills are designed for serious DIY enthusiasts and professional tradespeople who need consistent accuracy in metal and wood drilling. The range includes models suitable for home workshops and industrial settings. The PBD 40, for instance, is ideal for those who regularly drill large holes in steel up to 40 mm diameter. The PBD 20 serves lighter tasks such as drilling timber and thin sheet metal.
Performance and key specifications
Bosch pillar drills are known for their powerful motors and electronic speed control. The PBD 40 features a 1,010 W motor that delivers high torque even at low speeds. This allows drilling through tough materials without stalling. The electronic speed control maintains a constant speed under load, which is crucial for clean holes. The PBD 20 has a 710 W motor, which is sufficient for most DIY tasks. Both models offer a range of speeds from 200 to 2,500 rpm, allowing you to match the speed to the material and bit size.
Build quality and design
Bosch builds its pillar drills with robust materials. The PBD 40 has a heavy-duty cast iron base and column for stability. The drill head is made from die-cast aluminium. The chuck is a keyless type for quick bit changes. The depth stop is easy to set and holds its position. The PBD 20 uses a lighter construction but still feels solid. Some owner reviews note that the plastic belt cover on the PBD 20 feels less durable than the metal cover on the PBD 40. Both models have a built-in work light, which is a useful feature for illuminating the work area.
Alternatives to consider
If Bosch models are out of budget, consider the DeWalt DWE1622K for similar power and build quality. The Makita DPB184Z is a cordless option for those who want portability. For a more affordable option, the Ryobi RDP102 is a good choice for light DIY use. The Einhell TC-BD 500 is another budget-friendly option that offers decent performance for the price.
What to check before buying a pillar drill
Before buying a pillar drill, check the motor power. A higher wattage motor can drill larger holes and handle tougher materials. Check the drilling capacity in steel, as this indicates the maximum hole size the drill can make. The speed range is important for matching the drill speed to the material. A wider speed range gives more versatility. Also check the throat depth, which is the distance from the chuck centre to the column. A larger throat depth allows drilling wider workpieces. Finally, consider the weight and stability of the drill. A heavier drill is more stable and reduces vibration.
Mistakes to avoid when buying a pillar drill
One common mistake is buying a drill with too little power for your needs. A 500 W drill may struggle with 20 mm holes in steel. Another mistake is ignoring the speed range. Some drills have a limited speed range, which can make them unsuitable for small bits or large holes. Also, avoid buying a drill with a small throat depth if you plan to drill large workpieces. Finally, do not overlook the build quality. A cheap drill with a plastic column may flex under load, leading to inaccurate holes.
