How to Choose the Right Drill Accessories

Material Compatibility: Different substrates demand specific accessory types for optimal results. HSS bits handle metal, plastic and wood effectively, whilst carbide-tipped accessories are essential for tile, glass, masonry and other abrasive materials. Using inappropriate accessories not only delivers poor results but risks damaging both the workpiece and the accessory itself. Always verify material suitability before purchasing.

Tool Compatibility: Check shank diameter and fitting type to ensure accessories match your power tool's chuck capacity. Rotary multi-tools typically accept smaller 3.2mm shanks, whilst standard drills accommodate various sizes up to 13mm. Some accessories are designed exclusively for specific tool systems, so verify compatibility with your equipment before ordering.

Coating and Quality: Titanium-coated bits offer substantially longer service life and improved cutting performance compared to uncoated alternatives. Whilst the initial cost is higher, the extended lifespan and superior results provide better value for regular professional use. For occasional DIY applications, standard HSS accessories represent adequate performance at lower investment.

Application Requirements: Consider the precision and finish quality your work demands. Brad point bits deliver cleaner holes in timber than standard twist bits, whilst specialist glass drill bits feature unique geometries preventing cracking. Drywall cutting bits create smooth apertures for electrical boxes, and carbide sanding drums tackle grinding tasks that would quickly destroy standard abrasives. Match accessory design to specific applications for optimal outcomes.

Set versus Individual Items: Accessory sets offer versatility and value for tradespeople handling varied work, providing comprehensive size ranges in organised storage cases. Individual specialist bits suit those with specific recurring tasks or particular material requirements. Evaluate your typical workload patterns to determine the most economical purchasing approach.

Brand Reputation: Established manufacturers like Dremel and Draper engineer accessories to exacting tolerances, ensuring consistent performance, accurate sizing and safe operation. Premium accessories maintain sharpness longer, operate more smoothly, and are significantly less likely to fail during use compared to budget alternatives.

Safety Information

Working safely with drill accessories is essential for preventing injury and achieving quality results. Always wear appropriate eye protection meeting BS EN 166 standards when drilling, as material fragments, metal swarf and dust particles can cause serious eye injuries. Safety goggles should provide adequate side protection and fit securely during operation.

Ensure accessories are correctly fitted and tightened before starting work. Loose bits can slip, vibrate excessively or eject during use, causing injury or damaging the workpiece. Check that accessories are rated for your power tool's maximum speed - exceeding manufacturer's RPM ratings can cause catastrophic bit failure with dangerous consequences.

Allow bits to cool naturally after use, particularly following metalwork or masonry drilling. Hot accessories can cause serious burns if handled immediately. Never force a drill bit through resistant material - apply steady, controlled pressure and allow the accessory to cut at its designed rate. Forcing generates excessive heat, accelerates wear and increases breakage risk.

Inspect drill accessories regularly for wear, damage or cracks before use. Discard any damaged items immediately as they can shatter during operation, projecting dangerous fragments. When working at height or on busy sites, secure power tools and accessories properly to prevent drops that could injure those below.

Follow HSE guidelines for dust exposure, particularly when drilling materials producing hazardous dust such as silica-containing masonry or manufactured boards containing formaldehyde. Use dust extraction systems where possible and wear appropriate respiratory protection in accordance with COSHH regulations when working with hazardous materials.

Frequently Asked Questions

What's the difference between HSS and titanium-coated drill bits?
HSS (High-Speed Steel) bits are manufactured from hardened steel alloy, whilst titanium-coated bits feature an additional titanium nitride surface layer applied through a specialised coating process. This coating reduces friction and heat generation, extending bit life up to six times longer than uncoated HSS equivalents. Titanium-coated bits maintain their sharpness significantly better and justify the additional investment for regular professional use, though standard HSS bits perform adequately for occasional DIY applications.

Can I use the same drill bit for wood, metal and masonry?
Whilst multi-purpose bits exist for light-duty applications, using material-specific accessories delivers superior results and safer operation. Wood bits feature different cutting geometries and angles compared to metal bits, and masonry demands carbide tips to handle abrasive materials effectively. Using inappropriate accessories causes overheating, rapid wear, poor finish quality and potential dangerous bit breakage. For professional results and equipment longevity, always match the accessory to your substrate material.

How do I know which shank size my tool accepts?
Check your power tool's instruction manual or examine the chuck capacity markings, typically stamped on the chuck body itself. Common sizes for rotary multi-tools are 3.2mm, whilst standard drills usually accommodate shanks from 1.5mm up to 13mm depending on chuck size. Some tools use quick-change systems with specific proprietary fitting types. When purchasing accessories, always verify compatibility with your specific tool model to ensure proper fit and safe operation.

Why do my drill bits keep breaking during use?
Bit breakage typically results from several common causes: excessive pressure forcing the cut, incorrect speed settings for the material, using worn or damaged accessories, or drilling materials the bit isn't designed for. Apply steady, moderate pressure rather than forcing the tool through resistant material. Reduce speed when drilling metal to prevent overheating, and increase speed for timber. Ensure bits remain sharp - dull accessories require excessive pressure and generate dangerous heat levels. Always use the correct bit type for your substrate material.

How should I store drill accessories to maximise their lifespan?
Store accessories in dedicated cases or organisers that keep individual bits separated and protected from moisture and physical damage. Avoid loose storage where bits can knock together, damaging delicate cutting edges. Keep accessories clean and dry - wipe off cutting residue, swarf and dust after use, and apply a light oil coating to prevent rust on steel bits. Store in a dry environment away from temperature extremes and damp conditions. Keep precision bits in their original protective sleeves when possible to prevent edge damage.
