3-Pack Titanium Coated Step Drill Bits Hex Shank HSS 3–12mm
3-Pack Titanium Coated Step Drill Bits Hex Shank HSS 3–12mm
3-Pack Titanium Coated Stepped Drill Bits with Hex Handle (3–12mm)
Tackle any drilling project with confidence using this 3-piece set of titanium-coated stepped drill bits. Engineered from premium High Speed Steel (HSS) and finished with a titanium coating, these step drill bits are built to cut through metal, wood, plastic, and thin sheet materials with precision and ease — making them an indispensable addition to any toolbox.
Why You'll Love These Step Drill Bits
- Titanium Coating: Reduces friction and heat build-up during drilling, extending bit life and maintaining sharper cutting edges for longer.
- Two-Flute Design: The dual-flute spiral geometry delivers faster, smoother, and cleaner holes with minimal burring on the exit side.
- Stepped Design (3–12mm): A single bit handles multiple hole sizes — no need to swap bits constantly. The clearly marked steps make sizing quick and accurate.
- Hex Handle Shank: The 1/4" hex shank fits securely into most power drills and quick-change chucks, preventing slipping for safer, more controlled drilling.
- High Speed Steel Construction: HSS provides exceptional hardness and heat resistance, making these bits suitable for use on mild steel, aluminium, copper, plastic sheeting, and more.
- 3-Piece Set: Three bits covering a practical range of stepped diameters, giving you versatility for a wide variety of projects.
Ideal Applications
- Drilling clean, sized holes in sheet metal and thin steel panels
- Electrical and plumbing rough-in work (conduit holes, junction boxes)
- Automotive bodywork and chassis modifications
- DIY home improvement and workshop fabrication
- Woodworking and plastic sheet projects

Safe & Smart Drilling Tips
Always wear appropriate eye protection when drilling, use cutting fluid on metal surfaces to prolong bit life, and secure your workpiece firmly before starting. For further guidance on tool safety best practices, visit the OSHA Hand & Power Tools Safety Resource.
Frequently Asked Questions
Q: What materials can these titanium coated stepped drill bits cut through?
A: These HSS stepped drill bits are designed primarily for drilling through metal (mild steel, aluminium, copper), as well as wood, plastic sheeting, and thin sheet materials. The titanium coating reduces friction and heat, making them well-suited for tougher materials that would wear standard bits more quickly.
Q: What size holes do these stepped drill bits create?
A: The stepped drill bits cover a size range of 3mm to 12mm. Each step on the bit corresponds to a specific diameter, so one bit can create multiple hole sizes — simply drill to the marked step that matches your required hole diameter.
Q: Will these bits fit my existing power drill?
A: Yes. The hex shank handle is designed to fit standard 1/4" quick-change chuck systems as well as most conventional drill chucks. The hex shape also prevents the bit from rotating or slipping in the chuck during use, giving you a more secure and controlled drilling experience.
Q: How do I extend the life of these drill bits?
A: To maximise the lifespan of your stepped drill bits, use a suitable cutting fluid or lubricant when drilling metal, avoid excessive pressure (let the bit do the work), and start at a lower speed before increasing. Store bits in their case or a dry location to prevent corrosion.
