Sirius has established itself as a trusted name in precision drilling solutions, offering an excellent range of cone and stepped drill bits designed for professionals and serious DIY enthusiasts across the UK. These versatile bits are engineered to drill multiple hole sizes with a single tool, eliminating the need for constant bit changes and significantly improving workflow efficiency on site.

Whether you're working with sheet metal, plastic, aluminium or other thin materials, Sirius cone and stepped drill bits deliver clean, burr-free holes with exceptional accuracy. Their stepped design allows for precise hole enlargement and chamfering in one operation, making them indispensable for electricians, plumbers, HVAC engineers and metal fabricators who demand reliability and performance from their drilling equipment.

Why Choose Sirius?

Sirius cone and stepped drill bits stand out in the market for several compelling reasons:

• Superior Material Construction: Manufactured from high-speed steel (HSS) with titanium nitride coating for enhanced durability and heat resistance during extended drilling operations
• Precise Step Graduations: Clearly marked size increments ensure accurate hole sizing every time, reducing costly mistakes on critical jobs
• Self-Centring Point: Eliminates the need for pilot holes and prevents bit walking, delivering cleaner results with less effort
• Extended Tool Life: Advanced coatings and heat treatment processes mean Sirius bits maintain their cutting edge longer than standard alternatives
• Versatile Application: Suitable for use with standard drills, magnetic drills and drill presses, providing flexibility across various trades

Popular Sirius Products

Sirius offers a comprehensive selection of cone and stepped drill bits to suit different applications and material thicknesses. Their range typically includes multiple step configurations, from compact bits with 3-4 steps for precision electrical work, through to larger diameter models with 10-12 steps for more demanding fabrication tasks. Each bit is designed with a three-flat shank to prevent slipping in the chuck, ensuring safe and secure operation throughout your project.

Frequently Asked Questions

What materials can I drill with Sirius cone and stepped drill bits?

Sirius cone and stepped drill bits are ideal for drilling sheet metal, stainless steel (up to 2mm), aluminium, copper, brass, plastic, plywood and fibreglass. They're particularly effective on materials up to 4mm thick, though this varies by specific bit model.

Do I need special equipment to use stepped drill bits?

No, Sirius stepped drill bits work with any standard drill capable of accepting their shank size. For best results, use a variable speed drill and start at lower speeds (around 500-1000 RPM) for metal work, increasing as needed for softer materials.

How do I maintain my Sirius stepped drill bits?

Keep bits clean and free from metal swarf after each use. Apply cutting fluid when drilling tougher metals to reduce heat build-up. Store bits properly to protect the cutting edges, and periodically check for damage or excessive wear.
