They are not intended for use on wood or metal.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need a special drill to use these bits?\u003c\/h4\u003e\n\u003cp\u003eA: No special drill is required. The hex shank is compatible with most standard power drills and drill presses that accept hex-shank bits. For best results, use a variable-speed drill so you can start at a low RPM and increase gradually.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Should I use water when drilling with diamond bits?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — using water as a coolant is strongly recommended. It reduces heat build-up on the bit and the tile surface, which extends the lifespan of the diamond coating and helps prevent cracking or chipping of the material being drilled.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What sizes are included in this set?\u003c\/h4\u003e\n\u003cp\u003eA: This set includes four drill bits: 6mm, 8mm, 10mm, and 12mm — covering the most common hole sizes needed for tile and masonry work, such as installing towel bars, shower fixtures, anchors, and cabinet hardware.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long will these diamond drill bits last?\u003c\/h4\u003e\n\u003cp\u003eA: Longevity depends on the hardness of the material, drilling speed, pressure applied, and whether cooling water is used. Vacuum brazed diamond bits generally last significantly longer than electroplated alternatives due to the stronger diamond-to-steel bond. Following the pro tips above will maximize bit life.\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 diamond drill bit set cut through?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"These vacuum brazed diamond drill bits are designed for hard masonry surfaces including porcelain tile, ceramic tile, granite, marble, slate, travertine, and similar stone or glass materials.
