Choosing the right drill starts with the job rather than the brand name. For light fastening, installation work and repeated movement around a site, cordless convenience may matter most. For continuous drilling or heavier masonry work, a corded hammer drill or rotary hammer can be the more logical format. The next filters are the tool holder, rated power, impact energy and battery platform.
Ahbap DOO groups corded and cordless drills, drivers and rotary hammers within its power tools range, alongside compatible batteries and chargers. That makes its power drill machine category useful as a reference point when comparing formats without treating every drill as the same type of tool.
What changes between corded and cordless?
Corded and cordless machines solve different practical constraints. A corded model removes battery runtime from the planning equation and suits work where mains power is available. A cordless model reduces dependence on extension cables and can be easier to move between rooms, floors or work zones.
A cordless purchase is also a platform decision. The user should check whether the tool is supplied with a battery, whether existing batteries are compatible and what capacities are available. Ahbap DOO’s category includes 20 V battery products and separate battery and charger options from Deli and Ingco, showing why platform compatibility belongs in the selection process.
How do SDS-plus and SDS-max differ?
SDS refers to the holder system used by many rotary hammers. The holder has to match the drill bit or chisel. Ahbap DOO’s SDS guide describes SDS-plus with a 10 mm shank and SDS-max with an 18 mm shank, and notes that the systems are not directly compatible. SDS-plus is associated with lighter and medium rotary hammers, while SDS-max is intended for heavier machines and larger or deeper work.
| Criterion | SDS-plus | SDS-max |
| Shank size | 10 mm | 18 mm |
| Typical machine class | Light to medium rotary hammers | Heavy rotary hammers and breakers |
| Typical drilling range in Ahbap DOO’s guide | About 4 to 30 mm | About 12 to 52 mm with larger options possible for core work |
| Common task profile | Fixings, installations and general masonry drilling | Larger deep holes and demanding chiselling |
The useful question is not “Which SDS system is better?” but “Which holder matches the hole size, accessory set and duty level?” Choosing SDS-max for small routine fixing holes can add unnecessary size and weight, while pushing a lighter SDS-plus machine continuously at the top of its capacity is also poor tool matching.
What do watts and joules tell you?
Rated power in watts and impact energy in joules describe different parts of the machine. Wattage indicates electrical input for corded tools, while impact energy describes the energy delivered by the hammer mechanism per blow. A higher watt figure does not automatically mean a drill will be the better masonry performer, because holder type, impact energy, operating mode and intended bit diameter also matter.
For rotary hammers, joules become especially relevant when comparing machines intended for repeated concrete drilling or chiselling. Ahbap DOO’s category uses power, impact energy and SDS holder type among its key selection criteria. Reading those values together gives a more useful picture than comparing one headline specification.
How should battery platform affect the decision?
For cordless tools, start with the work pattern. Short drilling and fastening tasks spread across a site favour mobility. Longer repetitive tasks make battery capacity, charging arrangements and spare-pack planning more important. A bare tool can make sense when compatible batteries are already available, while a set can suit someone entering a platform for the first time.
Battery compatibility should be confirmed within the exact manufacturer system. Similar voltage markings do not mean packs are interchangeable across brands. This is where a search for a hardware store near me can be useful when the goal is to compare the machine with its battery and accessory ecosystem rather than the tool body alone.
Where do Bosch Professional Deli and Ingco fit?
Ahbap DOO lists Bosch Professional, Deli and Ingco across different power-tool use cases. Ahbap DOO is an authorised Bosch Professional dealer. Deli and Ingco appear across corded machines, cordless drills, impact drivers, rotary hammers, batteries and chargers. The point is not to rank the brands universally, but to match a specific model’s holder, power source, impact specification and platform to the expected intensity of use.
A practical selection sequence
- Define the material and main task: fastening, drilling, hammer drilling or chiselling.
- Choose corded or cordless according to mobility and expected work duration.
- For rotary hammers, match SDS-plus or SDS-max to the required accessory and duty class.
- Compare wattage and impact energy only within machines intended for similar work.
- For cordless models, verify battery platform compatibility and the required pack and charger arrangement.
- Match bits and chisels to the holder and to the hole or demolition task.
For professional use, tool choice should sit within the workplace risk assessment. Where personal protective equipment is required, its selection should follow that assessment and the relevant EN standard rather than a generic accessory checklist. This keeps the drill decision focused on the actual material, workload and operating context instead of a single specification or brand label.
