Description

  • Flat Head Design for Stable Drilling – Features precision flat heads that create steady contact with hard surfaces (glass, ceramic, stone, jewelry, metal), reducing slippage during initial drilling. The 60-grit diamond coating enables efficient material removal, ensuring clean, controlled holes—ideal for diamond drill bits for glass and diamond drill bits for ceramic projects requiring consistency.
  • 4 Essential Sizes in 30-Piece Set – Includes 10 x 1mm, 10 x 2mm, 5 x 1.5mm, and 5 x 2.5mm flat head bits to cover diverse needs. From tiny holes in jewelry to medium openings in stone, this assortment eliminates the need for multiple sets. Perfect for users seeking diamond tip drill bit versatility for crafts, DIY tasks, and precise work.
  • 23.5mm Shank for Rotary Tool Fit – Each flat head bit has a 23.5mm shank that works seamlessly with most standard rotary tools, enabling immediate use without extra adapters. The secure fit minimizes wobbling, enhancing accuracy even when working with fragile materials like glass. A key choice for anyone using diamond core drill bit applications regularly.
  • Durable high-quality diamond sand – Made with high-quality diamond sand to withstand repeated use on tough surfaces. The flat head design distributes pressure evenly, reducing wear and maintaining sharpness over time. These bits outperform flimsy alternatives for reliable, long-lasting performance.
  • Cooling Tips for Extended Life – For optimal durability, use water (submerged or drip) to prevent overheating during operation—avoid dry drilling. The 30-piece quantity ensures easy replacement of worn bits, making the set a cost-effective solution for hobbyists needing diamond drill bits for stone and regular crafting tasks.
