Best Bosch Professional cordless combi drill

Updated: 22 October 2026

The safest way to mis-buy is to take the biggest newton-metre figure and ignore the carton. The best Bosch Professional cordless combi drill in this set is the GSB 18V-110 C in an L-BOXX, if you already own Bosch Professional 18 V batteries and you need that capacity. Otherwise a compact 65, a complete 25 kit, or the 12 V set is closer. A five-star line from three reviews does not overturn that. Prices and stars are on the [Bosch professional cordless combi drill comparison](/hub/drilling-and-accessories/bosch-professional-cordless-combi-drill). There was no lab test, and a qualifying purchase can earn a commission at no extra cost to you.

The high-torque pick, with a condition

B083QMJR8Y is the GSB 18V-110 C with an auxiliary handle and L-BOXX 136, no battery, at £186.00. The listing states 110 Nm, a 13 mm chuck, 82 mm in wood and 13 mm in metal. Amazon shows 4.7 from 795 reviews. Bosch states masonry to 16 mm and about 1.9 kg without a battery. It is the top pick if the packs are already yours. It is too fast for easy screws, and Bluetooth is not included. The cardboard twin, B083QM7PLT, is £149.99, 4.6 from 222 reviews, with chuck complaints. Other questions are on the buying guide.

The compact 18 V pick

The GSB 18V-65 is a 175 mm brushless head, listed at 1.1 kg. B0DQV7T3GJ is the body and L-BOXX at £84.99, no battery, 4.7 from 35 reviews. The 175 mm chuck cell is the head length, not a jaw. Cells say 55 Nm and a bullet says 65 Nm. It is the best value if you already own 18 V packs. B0DSQ5D79J is the kit at £199.98, 5.0 from three reviews, and one box held 4.0 Ah packs. B0FJSJTMDW, the GSB 18V-25 at £149.99 with two 4.0 Ah batteries, is called brushed in UK reviews. Take it when you own no packs.

The small-set pick

B07ZKXYKVB is a 12 V set: GSB 12V-15, GDR 12V-105, two 2.0 Ah batteries and a bag, at £239.99, 4.7 from 305 reviews. Reviewers like it for kitchens and say it is not for the heaviest work. Bosch states 10 mm masonry. The 120 Nm amazon figure is not split between the two tools. Choose it when position is the problem and the packs will not run an 18 V GSB. That split is the 12 V or 18 V page. A lintel is the combi versus SDS page.

What best cannot mean here

A top pick here is the most reviewed high-torque body, for someone who already has the right batteries. The 65 kit’s 5.0 from three reviews loses to 4.7 from 795 once the sample is counted. The £84.99 65 is the best value only with a battery you already own. Hammer mode is a ratchet, and 16 mm masonry is not a lintel brief. The 175 mm chuck, 2.6 rpm and 12.7 cm cells are listing conflicts. Open the carton and try the chuck.

Common questions

Which of these six should I buy if I want one drill for site work?
If you already have Professional 18 V packs, the L-BOXX GSB 18V-110 C at £186.00 is the site pick: 110 Nm, 4.7 from 795 reviews, and Bosch’s 16 mm masonry line. Fit the side handle. With no packs, the £149.99 GSB 18V-25 kit is the complete brushed carton.
Is the L-BOXX 110 C better than the cheaper cardboard one?
It is the same torque class, £36 more, with a case and a much larger review count. The cardboard listing at £149.99 is where UK reviews describe bits falling out and a chuck that jammed. Prefer the L-BOXX unless you will test the chuck immediately and you do not need the case. Neither includes a battery.
Is a 5.0 score from three reviews a reason to prefer the 65 kit?
No. Three UK reviews can all be positive and still tell you less than 795 reviews on the 110 C or 222 on the cardboard twin. Use the 5.0 line as no defect written up in those three, not as proof the kit is the best drill. One of the three also describes 4.0 Ah packs against a 5.0 Ah title.
Who should skip the 110 C?
Skip it for easy screws, long overhead work, or if you have no 18 V battery and do not want to buy one. Bosch lists the body around 1.9 kg before the pack. The 65, the 25 kit or the 12 V set is the nearer match.
Is the 12 V set a best combi or a different job?
It is a different job. At £239.99 and 4.7 from 305 reviews it is well reviewed for kitchens and tight spaces, and reviewers say it is not for the heaviest work. You get a combi and an impact driver. You do not get an 18 V site drill, and the packs will not run the other five tools.
What does the badge on the comparison mean in plain English?
The top pick is the L-BOXX 110 C, because it leads the editorial score once review count is weighed. The best value badge is the £84.99 65 body, because it is the lowest price for a brushless tool and a case when you already own batteries. Neither badge is a lab prize, and neither sentence is a UK-wide superlative.
