How to Choose the Right Angle Drills

Selecting the appropriate angle drill requires careful consideration of several key factors:

Voltage Platform and Power Requirements: 12V models like the Bosch GWB series offer exceptional compactness for extremely tight spaces and lighter materials, whilst 18V options from Makita's LXT range, DeWalt's XR series, and Milwaukee provide the versatile middle ground suitable for most professional applications. For the most demanding work involving large diameter bits or dense materials, consider 40V-54V platforms such as Makita's XGT or DeWalt's Flexvolt systems.

Motor Technology: Brushless motors deliver superior efficiency, longer runtime, increased power-to-weight ratio, and extended tool longevity compared to brushed alternatives. Whilst brushless models command a premium price, the performance benefits and reduced maintenance make them worthwhile investments for professional users who depend on their tools daily.

Chuck Capacity and Head Size: Consider the maximum drill bit diameter you'll regularly use and ensure the chuck size accommodates your requirements. Additionally, measure the head height – ultra-compact models designed for stud and joist work feature narrower head profiles specifically engineered to fit within standard 89mm (3.5") joist spacing found in UK construction.

Speed and Torque Specifications: Variable speed control and multiple torque settings provide greater versatility across different materials and applications. Two-speed gearboxes offer the flexibility to switch between high-speed drilling in soft materials and high-torque boring through dense hardwoods or metal.

Ergonomics and Handling: The tool's balance, grip design, and weight distribution significantly impact user comfort during extended use. Side handles, rubber overmould grips, and well-positioned controls reduce operator fatigue, particularly important when working overhead or in awkward positions.

Battery Compatibility and Ecosystem: If you already own cordless tools from a particular manufacturer, selecting an angle drill within the same battery platform provides cost savings and operational convenience. The major brands – Makita, DeWalt, Milwaukee, and Bosch Professional – all offer comprehensive cordless ecosystems with interchangeable battery systems.

Safety Information

Safe operation of angle drills requires adherence to proper working practices and appropriate personal protective equipment:

Personal Protective Equipment: Always wear appropriate safety glasses or goggles to protect against flying debris and wood chips. Hearing protection is advisable during extended use, particularly with higher-powered corded models. Work gloves provide improved grip and hand protection, though ensure they fit properly to prevent snagging hazards.

Work Environment Considerations: Before drilling, always check for hidden cables, pipes, and services using appropriate detection equipment to comply with HSE guidelines. When working at height or in loft spaces, ensure proper access equipment and adequate lighting. Be particularly cautious when drilling overhead as the compact design can make it challenging to maintain secure grip during operation.

Electrical Safety: For corded models, inspect cables regularly for damage and ensure compliance with UK electrical standards including proper earthing and use of RCD protection, particularly on construction sites. Cordless tools should only be charged using the manufacturer's specified chargers, and damaged batteries must be disposed of properly through appropriate recycling channels.

Safe Operating Practices: Secure workpieces properly before drilling, maintain firm two-handed control where possible, and never force the tool – let the drill bit do the work. Be aware that right-angle drills can generate significant reactive torque, particularly when larger bits bind in materials. Start drilling at slow speeds until the bit is properly engaged, then increase to working speed.

Frequently Asked Questions

What's the difference between an angle drill and a standard drill with a right-angle attachment?

Dedicated angle drills are purpose-built with the motor and gearbox positioned for optimum balance and power delivery in the right-angle configuration, resulting in superior ergonomics, better power transfer, and more compact head profiles. Right-angle attachments add significant length and reduce torque transmission, making them less effective for professional applications requiring regular use in confined spaces.

Can angle drills be used for driving screws as well as drilling?

Yes, most modern angle drills feature adjustable torque settings and variable speed control that make them suitable for both drilling and light-duty screw driving. However, for extensive fastening work, a dedicated impact driver provides better performance and ergonomics. Angle drills excel at access rather than production fastening.

What head height do I need for drilling between standard UK joists?

Standard UK floor joists are typically 89mm (3.5 inches) deep. Look for angle drills specifically marketed as "stud and joist" models with head heights of approximately 80mm or less to comfortably fit within this spacing. Manufacturers like DeWalt and Makita offer ultra-compact models designed specifically for this application.

Are brushless angle drills worth the extra cost?

For professional tradespeople using angle drills regularly, brushless motors deliver significant advantages including approximately 50% longer runtime per charge, increased power output, reduced heat generation, and elimination of brush replacement maintenance. The initial premium typically pays for itself through improved productivity and tool longevity. DIY users with occasional requirements may find brushed models adequate for their needs.

Which voltage platform provides the best balance for general trade work?

The 18V platform remains the sweet spot for most professional applications, offering excellent power-to-weight ratios and the widest selection of compatible tools within manufacturer ecosystems. 12V models suit electricians and specialists requiring maximum compactness, whilst 40V-54V systems benefit users regularly drilling large diameter holes or working with dense hardwoods and metalwork.
