Ideal for countertop faucet holes, plumbing lines and masonry projects. - 【FAST CUTTING TURBO SEGMENTS】 Turbo diamond segments deliver aggressive, efficient drilling through dense stone and masonry while helping produce smooth, clean holes with reduced chipping. Designed for both wet and dry drilling. - 【10MM LONG-LIFE DIAMOND SEGMENTS】 Unlike surface-coated diamond bits, the 10mm diamond-bearing segments provide a deep, consumable working layer that continues cutting as the segments gradually wear down. Laser welded to the steel body for a strong, stable bond during demanding drilling. - 【1-3/8" CORE BIT, 5/8"-11 THREAD】 35mm (1-3/8") diameter with 100mm overall length and standard 5/8"-11 thread. Fits compatible angle grinders directly; drills and SDS Plus machines require the correct adapter. - 【EASY START WITHOUT PILOT BIT】 Start drilling at about a 30° angle to create a guide groove, then gradually bring the diamond hole saw upright and continue with steady, light pressure. Do not use hammer or impact mode. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076LCFN4Y | | Best Sellers Rank | #32,363 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #14 in Core Drill Bits | | Brand | SHDIATOOL | | Brand Name | SHDIATOOL | | Customer Reviews | 4.4 out of 5 stars 1,366 Reviews | | Cutting Angle String | 30 degrees | | Cutting Diameter | 35 millimeters | | Finish Type | Steel | | Finish Types | Steel | | Manufacturer | SHANGHAI DIATOOL CO., LTD. | | Material | Artificial diamond and Steel body | | Material Type | Artificial diamond and Steel body | | Number of Flutes | 2 | | Number of Packs | 1 | | Number of Pieces | 1 | | Part Number | A6880435.AUS | | Shank Type | Threaded | | Surface Recommendation | Stone | | Tool Flute Type | Straight | | UPC | 718760495270 | | Unit Count | 1 Count | ## Product Details - **Cutting Angle String:** 30 Degrees - **Cutting Diameter:** 35 Millimeters - **Finish Type:** Steel - **Material:** Artificial diamond and Steel body - **Shank Type:** Threaded ## Images ![SHDIATOOL Diamond Core Drill Bits 1-3/8 Inch for Concrete, Marble, Granite and Multi Stone Laser Welded Dry or Wet Hole Saws 35mm 5/8"-11 Thread - Image 1](https://m.media-amazon.com/images/I/61Et7MMnkUL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - SHDIATOOL Diamond Core Drill Bits 1-3/8 Inch for Hard Stone Concrete Marble Granite Brick Laser Welded Dry or Wet Hole Saws 35mm - SHDIATOOL Adapter for Core Bits 5/8-Inch-11 to M14 Thread --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/75472856-shdiatool-diamond-core-drill-bits-1-3-8-inch-concrete](https://www.desertcart.co/products/75472856-shdiatool-diamond-core-drill-bits-1-3-8-inch-concrete) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-10-15*
