The four-flute eccentric step design is specifically engineered to reduce chipping and cracking on brittle surfaces like glass and ceramic tile. For best results, apply steady, moderate pressure and allow the bit to work at a consistent speed without forcing it through the material.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What drill types are compatible with these hex shank step drill bits?\u003c\/h4\u003e\n\u003cp\u003eA: These bits feature a standard hex shank that fits virtually any drill with a hex chuck or adapter, including cordless drills, hand drills, and bench\/table drills. Simply insert the hex shank into the chuck and tighten for a secure, wobble-free fit.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need water or coolant when using these step drill bits on tile or concrete?\u003c\/h4\u003e\n\u003cp\u003eA: No. These hard metal alloy bits are rated for dry drilling, meaning you can drill directly into tiles, concrete, and brick without water or coolant. However, using intermittent drilling strokes and short pauses can help manage heat buildup during extended use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What sizes are included in this 5-piece step drill bit set?\u003c\/h4\u003e\n\u003cp\u003eA: The set includes 5 drill bits covering step sizes of 6mm, 8mm, 10mm, and 12mm, giving you the versatility to drill a range of hole sizes without needing to change bits — ideal for plumbing, electrical, and tile installation projects.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Can these 4-flute step drill bits be used on glass without cracking it?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
