Those who frequently work with hard surfaces and require precise, clean holes will find value. However, individuals needing bits for extremely dense concrete or metal drilling should consider specialized carbide or bi-metal sets, as these diamond bits are optimized for brittle materials. ## How to use 1. Choose the Semderm diamond hole saw bit size appropriate for your material (glass, tile, stone) and the desired hole diameter. Ensure the bit is securely attached to your drill chuck. — Select the Right Bit 2. Begin drilling at a slight angle to create a starting groove. Continuously apply water to the drilling area to cool the bit and flush away debris, which is crucial for longevity and preventing material cracking. — Apply Water Lubrication 3. Drill at a steady, moderate speed. Apply consistent, light to moderate pressure. Allow the diamond coating to do the work; do not force the bit. Once the hole is complete, clean the area and the bit. — Drill with Steady Pressure ## Product details | Field | Value | |---|---| | Coating | Diamond | | Base Material | Upgraded Carbon Steel | | Recommended Surfaces | Glass, Tile, Ceramic, Porcelain, Marble, Granite, Stone, Bottles | | Sizes Included | 6 mm (1/4"), 8 mm (5/16"), 10 mm (3/8"), 12 mm (1/2"), 14 mm (9/16"), 16 mm (5/8"), 18 mm (11/16"), 20 mm (4/5"), 22 mm (7/8"), 25 mm (1"), 25 mm (1-10"), 32 mm (1-1/5"), 35 mm (1-3/8"), 40 mm (1-3/5"), 50 mm (2") | | Drilling Tip | Diamond | | Cooling Method | Water Lubrication Recommended | | Cost per use | 15 bits at {{ccc_offer_price}} — {{ccc_price_per_unit:15:bit}} | | Shelf life after opening | N/A (Durable Tool) | | Contraindications | Not recommended for dense metal or concrete drilling; may chip brittle materials if excessive force is used. | | Allergens / common irritants | None | | Brand | Semderm | | Set Name | 15 PCS Diamond Hole Saw Drill Bit Set | | Number of Pieces | 15 | | Material | Carbon Steel with Nickel Plating | | Finish Type | Nickel | | Shank Type | Straight | | Item Weight | 323.18 grams (11.4 ounces) | | Package Dimensions | 5 cm x 9.6 cm x 11.6 cm | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### How to buy original Semderm diamond drill bits in India? Semderm diamond drill bits are imported directly from authorized US retailers and sold exclusively through crowcrowcrow.com. Each set is factory-sealed and comes with all customs duties and GST pre-paid, ensuring you receive authentic tools without hidden charges. Delivery is handled via ExpressBox for secure tracking across India. ### What materials can these diamond drill bits cut? These diamond drill bits are designed for hard, brittle materials including glass, ceramic tile, porcelain, marble, granite, stone, and bottles. They are ideal for creating clean holes in these surfaces. For drilling dense metal or concrete, specialized bi-metal or carbide-tipped bits are recommended. ### How do I ensure the best performance and longevity of the diamond bits? To maximize performance and extend the life of your Semderm diamond drill bits, always use water lubrication during drilling. This helps cool the bit, prevents overheating, and flushes away debris. Maintain a steady, controlled speed and avoid excessive force, especially on delicate materials. ### Are these drill bits suitable for drilling through glass bottles? Yes, these diamond drill bits are specifically designed to drill through glass bottles, as well as ceramic, porcelain, marble, and granite. The diamond coating ensures a sharp, precise cut on these hard surfaces. Remember to use water lubrication for best results and to prevent cracking. ### What is the size range of the diamond hole saw set? The Semderm 15-piece diamond hole saw set includes a comprehensive range of sizes from 6 mm (1/4") up to 50 mm (2"). This variety ensures you have the correct bit for most common drilling tasks on hard surfaces, from small holes to larger openings. ### Will the arbors fit my drill? The Semderm diamond hole saw set typically includes straight shank arbors designed to fit standard drill chucks. While specific arbor shank sizes are not detailed, these are generally compatible with common 10mm or 13mm chucks found on most corded and cordless drills. Always check your drill's chuck capacity. ### Can I use these drill bits for metal drilling? These diamond drill bits are optimized for hard, brittle materials like glass, tile, and stone. They are not designed for drilling dense metals. For metal drilling, you would typically need bi-metal or cobalt drill bits, which are specifically engineered to cut through steel and other alloys. ## Compliance Use eye protection and secure workpiece when drilling. Do not exceed rated RPM. Not intended for dense metal or concrete drilling. Keep out of reach of children when not in use. ## Images 1. https://images.crowcrowcrow.com/B0B9Y7KJPY-0.webp 2. https://images.crowcrowcrow.com/B0B9Y7KJPY-3.webp 3. https://images.crowcrowcrow.com/B0B9Y7KJPY-6.webp 4. https://images.crowcrowcrow.com/B0B9Y7KJPY-9.webp 5. https://images.crowcrowcrow.com/B0B9Y7KJPY-12.webp 6. https://images.crowcrowcrow.com/B0B9Y7KJPY-15.webp --- Source: https://crowcrowcrow.com/p/diamond-drill-bits-pcs-hole-saw-bit-set-tile-pot-glass-ceramic-bottles-porcelain-marble/tkm3706 Returns: 30 days, free, by mail.
