Combi Drills

About Combi Drills

Combi drills represent one of the most versatile power tools available, combining three essential functions in a single compact unit: rotary drilling, hammer drilling, and precision screwdriving with adjustable torque control. This multi-purpose design allows tradespeople and DIY enthusiasts to switch seamlessly between drilling wood, metal and plastic, tackling masonry work with hammer action, and driving screws with precise control. MyToolShed.co.uk stocks an extensive range of combi drills from leading manufacturers including Bosch Professional, DeWalt, Makita, Black and Decker, and Einhell, catering to both professional site work and home improvement projects.

Modern cordless combi drills feature brushless motor technology and high-capacity lithium-ion batteries that deliver performance rivalling traditional 240v corded alternatives. Available in voltage platforms from compact 12V models for confined spaces through to powerful 18V workhorses capable of handling demanding applications, these tools have become indispensable for anyone requiring reliable drilling and driving capabilities. The adjustable torque clutch enables precise control when fastening into different materials, whilst hammer action tackles brick, concrete and blockwork with ease, eliminating the need for multiple separate tools.

Applications

Combi drills serve a broad range of trades and applications across the UK construction and DIY sectors:

• General builders and contractors for fixing, fastening and drilling across multiple materials on site
• Electricians drilling cable routes, fixing back boxes and mounting electrical fittings
• Plumbers installing pipe brackets, fixing radiators and general mounting work
• Carpenters and joiners for wood drilling and driving screws in joinery applications
• Kitchen and bathroom fitters requiring versatile drilling for unit installation
• Maintenance engineers needing portable, multi-purpose drilling solutions
• DIY homeowners tackling furniture assembly, shelving installation and home improvements

Choosing The Right Combi Drills

Voltage Platform: 12V models offer exceptional portability for overhead work and confined spaces, whilst 18V drills deliver substantially more power for regular masonry drilling and demanding site applications.

Motor Technology: Brushless motors provide approximately 25-30% longer runtime per charge, increased power output and extended tool life compared to traditional brushed motors, making them ideal for professional users.

Torque Output: Entry-level models typically offer 30-40Nm for general household tasks, mid-range drills deliver 50-60Nm for demanding DIY work, whilst professional-grade machines reach 80Nm or higher for large masonry bits and substantial fixings.

Battery Capacity: Consider both Ah rating and number of batteries included. A 2.0Ah battery suits occasional users prioritising light weight, whilst 4.0Ah or 5.0Ah batteries better serve professionals requiring extended runtime between charges.

Build Quality: Professional brands engineer tools for daily site use with robust housings and metal gearboxes, whilst DIY-focused ranges offer excellent value for lighter-duty applications. MyToolShed.co.uk stocks both professional and DIY grades to suit every budget and requirement.

Safety Information

Always wear appropriate eye protection meeting BS EN 166 standards when operating combi drills to guard against flying debris. Remove jewellery, secure loose clothing and tie back long hair before use to prevent entanglement. When drilling overhead or working with masonry materials, wear a minimum FFP2-rated dust mask to avoid inhaling particulates, particularly silica dust which is regulated under COSHH regulations.

Always check for hidden cables and pipes using a suitable detector before drilling into walls, ceilings or floors. Inspect drill bits before use and discard any that are damaged or excessively worn, as these can shatter during operation. Ensure workpieces are securely clamped where possible and use appropriate access equipment when working at height.

Frequently Asked Questions

What's the difference between a combi drill and an impact driver?

A combi drill offers three functions—drilling, hammer drilling and screwdriving—with an adjustable clutch for precise torque control. An impact driver is specifically designed for driving screws and bolts using rotational impacts to deliver much higher torque without the adjustable clutch. For most users, a combi drill provides greater versatility.

What size combi drill do I need for drilling brick and blockwork?

For holes up to 10mm in brick and blockwork, a quality 12V combi drill with hammer action suffices for occasional use. However, for regular masonry drilling or holes larger than 10mm, an 18V model with at least 50Nm torque and a 4.0Ah battery provides much better performance and reduced user fatigue.

How long do combi drill batteries last?

Lithium-ion batteries typically maintain good performance for 300-500 charge cycles before capacity declines noticeably. With proper care—avoiding complete discharge, storing at moderate temperatures and using regularly—batteries often provide 3-5 years of reliable service.
