Bosch 18V Combi Drills
Drilling timber, metal and the odd brick fixing? A Bosch Professional 18V combi drill covers drilling, screwdriving and hammer drilling.
For fitters and maintenance teams, one chuck handles three jobs. Check torque, drilling capacities and supplied batteries before buying. Choose the model that suits your daily workload.
What Jobs Are Bosch Professional 18V Combi Drills Best At?
- Drill timber studs and noggins for first-fix brackets and cable routes, keeping the bit diameter within the drill's stated wood capacity.
- Drill metal brackets and steel sections with suitable HSS bits, hammer mode switched off and a speed matched to the bit diameter.
- Make fixing holes in brick and block for shelving, clips and brackets using masonry bits and hammer mode where appropriate for the substrate.
- Drive cabinet screws and general fixings with the adjustable clutch set to reduce overdriving into timber or board.
Choosing the Right Bosch Professional 18V Combi Drill
Buy for the largest holes you regularly drill, then check the weight with a battery fitted.
1. Capacity Before Maximum Torque
If you mainly drill pilot holes and fit cabinets, prioritise control and manageable weight. For larger timber bits, check the stated drilling capacity and any requirement for an auxiliary handle. A high torque figure alone does not tell you which bits the drill can safely run.
2. Brushless Motor and Safety Features
For frequent use, consider a Bosch Professional 18V brushless combi drill for its efficient motor and lack of replaceable carbon brushes. Check each model separately for features such as KickBack Control; these are not fitted across the entire range.
3. Body or Battery Kit
If you already own compatible Bosch Professional 18V batteries and a charger, a body-only drill avoids buying duplicates. Starting from scratch means checking the kit contents carefully, including battery capacity and charger, rather than comparing drill prices alone.
Who Uses a Bosch Professional 18V Combi Drill?
Kitchen fitters and joiners use these drills for pilot holes, cabinet assembly and wall fixings without changing tools for every task. Sparkies, plumbers and maintenance teams use a Bosch Professional 18V cordless combi drill for clips, brackets and installation work, particularly when they already run Bosch Professional 18V batteries.
The Basics: Understanding Combi Drill Modes
1. Drilling and Screwdriving
Drill mode rotates the bit for boring timber and metal without hammer action. Screwdriving mode uses an adjustable clutch to limit driving torque; start low and increase it until the screw seats correctly.
2. Hammer Drilling
Hammer mode adds rapid mechanical blows as a masonry bit turns. A Bosch Professional 18V hammer drill driver suits smaller brick and block fixing holes, but it does not replace an SDS-plus rotary hammer for repeated concrete drilling.
Accessories for Drilling and Fixing
Match the bit to the material and keep a charged battery available before starting a run of fixings.
1. Drill Bit Sets
Choose Bosch Drill Bit Sets with the materials and diameters you actually use. A mixed set saves hunting for separate bits, but check its contents before relying on it for masonry work.
2. Flat Wood Bits
Use Bosch Flat Drill Bits for timber holes where speed matters more than a fine finish. Stay within the drill's capacity and use the grip arrangement specified in its manual.
3. HSS Bits
Keep Bosch HSS Drill Bits for metal brackets and sections. The right bit, suitable speed and cutting lubricant where appropriate help avoid overheating and blunt cutting edges.
4. Batteries and Chargers
Check Bosch 18V Batteries & Chargers for compatible packs and charging options. A spare pack avoids stopping mid-installation, while a smaller pack can reduce weight for overhead work.
Choose the Right Bosch Combi Drill for the Job
Use your regular workload to narrow down the specification.
| Your Job | Combi Drill Choice | Key Features |
|---|---|---|
| Cabinet fitting and pilot holes | Compact model | Manageable fitted weight, controllable trigger and adjustable clutch. |
| Daily mixed installation work | Brushless model | Suitable timber and metal capacities, two-speed gearbox and compatible spare battery. |
| Larger timber holes | Higher-capacity model | Approved bit diameter, specified auxiliary handle and suitable battery. |
| Occasional brick fixing holes | Hammer-capable combi drill | Correct masonry capacity and suitable masonry bits. |
Common Buying and Usage Mistakes
- Buying by torque alone can leave you with an unnecessarily bulky drill. Compare drilling capacities, fitted weight and control features against your actual jobs.
- Expecting combi hammer action to handle repeated concrete holes wastes time and wears bits. Use an appropriate SDS-plus rotary hammer for that workload.
- Leaving hammer mode engaged for metal or timber gives poor results and unnecessary vibration. Check the mode selector whenever you change materials.
- Assuming every Bosch 18V battery fits can mean buying the wrong system. Bosch green DIY batteries are not interchangeable with Bosch Professional 18V packs.
Combi Drill vs Drill Driver vs Impact Driver
Combi Drill
Choose a Bosch combi drill when timber, metal and occasional masonry holes all feature in the same day's work. Hammer mode adds flexibility, but it is not the tool for sustained concrete drilling.
Drill Driver
A Bosch Professional 18V drill driver covers drilling and controlled screwdriving without masonry hammer action. Choose it if your work stays in timber and metal, comparing model dimensions and weight rather than assuming it will always be smaller.
Impact Driver
For repeated long screws and suitable structural fixings, Bosch 18V Impact Drivers provide rotational impacts through a hex bit holder. They complement a combi drill but do not offer the same adjustable screwdriving clutch.
Maintenance and Care
Clear Dust After Use
Remove the battery before cleaning. Brush dust from the vents and wipe the body clean without soaking it or forcing debris further inside.
Check Chuck and Bits
Keep bit shanks and chuck jaws clean so they grip properly. Replace damaged bits, and have persistent chuck slip or excessive play checked rather than tightening harder each time.
Store Dry
Dry the drill before putting it away and keep it out of damp van footwells. Follow the battery instructions for storage and charging temperatures.
Stop When Something Changes
Unusual noise, burning smells or damaged controls need attention. Stop using the drill and arrange inspection rather than working it until a repair becomes a replacement.

Bosch Professional 18V Combi Drill FAQs
What is the difference between a combi drill and a drill driver?
A combi drill adds hammer action for suitable masonry drilling to the drilling and screwdriving functions of a drill driver. Both handle timber and metal with the correct bits. Neither should be confused with an SDS rotary hammer for heavier masonry work.
Is the Bosch combi drill brushless?
It depends on the model. Bosch offers brushless combi drills, but do not assume every Bosch combi drill has a brushless motor. Check the individual specification before buying, particularly when comparing older models or discounted kits.
What battery does the Bosch combi drill use?
The drills in this category use the Bosch Professional 18V battery system, including compatible GBA 18V and ProCORE18V packs. Check the model's recommended battery specification for demanding work. Bosch green DIY 18V batteries do not fit this Professional system.
Are Bosch combi drills any good?
They are a practical option for trade drilling and fixing, especially if you already own Bosch Professional 18V batteries. The important distinction is between models: choose the capacity, weight and safety features your work needs. Even a high-spec combi drill is the wrong purchase for all-day concrete drilling.
Where are Bosch tools made?
Bosch manufactures tools in several countries, so there is no single country of manufacture for the whole range. Check the tool's rating plate or packaging for the specific unit. A German brand name does not mean every drill is manufactured in Germany.
