Product DescriptionProduct DescriptionPremium Quality Laser Welded Dry Core Drill BitOur Dry Diamond Core Drill Bits are specially designed for drilling holes in concrete, brick, block, and masonry without water cooling. Manufactured using premium-grade industrial diamonds and laser-welded segments, these dry core drill bits deliver fast cutting speed, long service life, and superior safety in demanding drilling applications.The segment design ensures smooth penetration, reduced friction, and stable drilling even on reinforced substrates. The barrels are made of high-strength steel to withstand high RPMs, while the segment bonds are optimized for dry cutting, preventing overheating and premature wear.Available in multiple diameters, our concrete dry core bits are compatible with angle grinders, hand-held core drills, and rotary hammers using appropriate adapters. They are ideal for HVAC installations, plumbing, electrical conduits, air-conditioning lines, and renovation works where water usage is restricted.Every bit undergoes strict quality inspections, including segment hardness testing, welding strength checks, barrel integrity inspection, and balance testing. This ensures that each dry core drilling tool provides consistent performance, long lifetime, and precise hole cutting.Detailed PhotoSpecificationDiameterTotal LengthSegment SizeSegment NumberConnection?68mm92mm24mm*10mm*3.8mm4M16?72mm92mm24mm*10mm*3.8mm4M16?82mm92mm24mm*10mm*3.8mm5M16Packaging & ShippingFAQFrequently Asked QuestionsQ: Can dry core bits drill reinforced concrete?A: Yes, with laser-welded segments, they cut both masonry and reinforced concrete.Q: Which machines are they compatible with?A: Hand-held core drills, angle grinders, and rotary hammers (with adapters).Q: Do you provide samples?A: Yes, samples available for testing before bulk order.Q: What is the delivery time?A: 7–15 days for standard sizes, longer for custom orders.Q: Do you offer OEM/ODM?A: Yes, with custom diameters, packaging, and logo branding.
