The titanium (TiN) coating reduces friction and heat, making it suitable for both soft and moderately hard materials.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the 4-32mm and 4-42mm versions?\u003c\/h4\u003e\n\u003cp\u003eA: Both versions use the same high-quality HSS 4241 construction and titanium coating. The 4-32mm version covers hole sizes from 4mm up to 32mm in steps, while the 4-42mm version extends the range up to 42mm — ideal for larger hole-cutting applications such as electrical conduit fittings or larger pipe holes.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Will this step drill bit fit in a standard drill chuck?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The 3-sided (tri-flat) shank is compatible with most standard keyless and keyed drill chucks. The flat sides prevent the bit from rotating or slipping in the chuck, ensuring safer and more precise drilling.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I extend the life of my titanium-coated step drill bit?\u003c\/h4\u003e\n\u003cp\u003eA: To maximise the lifespan of your step drill bit, use a moderate drilling speed (lower RPM for harder metals), apply cutting oil when drilling through metal, avoid excessive downward pressure, and clean the bit after each use. Avoid re-sharpening the titanium-coated edge, as this removes the protective coating.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What materials can this HSS titanium step drill bit cut through?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The SLADE HSS step drill bit is designed to cut through a wide range of materials including mild steel, stainless steel, brass, aluminium, copper, wood, MDF, plastic, and PVC.
