The cobalt steel alloy construction provides the hardness needed to drill cleanly through these tough substrates without excessive chipping.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What sizes are included in this drill bit set?\u003c\/h4\u003e\n\u003cp\u003eA: The set is available in four diameters: 6 mm, 8 mm, 10 mm, and 12 mm. This range covers the most common hole sizes needed for tile and glass work, from small fixture holes to larger openings for pipes or hardware.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is an eccentric (offset) drill bit and why does it matter for glass and tile?\u003c\/h4\u003e\n\u003cp\u003eA: An eccentric drill bit features an off-center cutting geometry that reduces the lateral stress applied to brittle materials like glass and ceramic tile as the bit enters the surface. This design minimizes cracking and chipping, resulting in cleaner, more precise holes compared to standard twist bits.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these bits compatible with standard drills?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The bits feature a standard round shank that fits most conventional corded and cordless drills. For best results on glass and tile, use with a variable-speed drill at a low, steady speed and apply gentle, consistent pressure.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What materials can the Cobalt Steel Eccentric Drill Bits cut through?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"These eccentric drill bits are designed for hard, brittle surfaces including glass, ceramic tile, porcelain tile, rock slabs, and similar materials.
