Much cleaner than using a demo-hammer to open up the concrete: looks much more professional. Would have prefered a set screw to retain the guide bit, but the provided release wedge works for clearing the bit for replacement. Problem being, not many sellers sell the tapered bits these days. ## Features - DRILLING DIAMETER：2-1/2 inch / 65mm - MATERIAL:Steel , Alloy and Diamond - ROD TYPE :1X 110mm SDS plus Adapter .Rotary only - DRILLING DEPTH:60mm drilling depth - FOR Dry / Wet Granite Marble Masonry Concrete Stone Brick and Block ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DKH2JDYS | | Best Sellers Rank | #116,328 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #508 in Hole Saws | | Brand Name | GRIXLEN | | Customer Reviews | 4.0 4.0 out of 5 stars (53) | | Cutting Diameter | 2.5 Inches | | Finish Types | Uncoated | | Included Components | connecting rod | | Manufacturer | GRIXLEN | | Material Type | Steel, Alloy, Diamond | | Number of Flutes | 2 | | Shank Type | SDS-Plus | | Surface Recommendation | Brick, Concrete, Granite, Marble, Masonry, Stone | | Tool Flute Type | Straight | | UPC | 769464515719 | ## Product Details - **Brand:** GRIXLEN - **Cutting Diameter:** 2.5 Inches - **Finish Type:** Uncoated - **Material:** Steel, Alloy, Diamond - **Shank Type:** SDS-Plus ## Images ![- 2-1/2 inch / 65mm Dry Diamond Core Drill Bit with SDS Plus Adapter, Concrete Core Drill Bit for Dry/Wet Drilling Granite Marble Masonry Concrete Brick Stone and Block (65mm (2-1/2 inch)) - Image 1](https://m.media-amazon.com/images/I/616XWJuq4rL.jpg) ![- 2-1/2 inch / 65mm Dry Diamond Core Drill Bit with SDS Plus Adapter, Concrete Core Drill Bit for Dry/Wet Drilling Granite Marble Masonry Concrete Brick Stone and Block (65mm (2-1/2 inch)) - Image 2](https://m.media-amazon.com/images/I/71PgXcfHTQL.jpg) ![- 2-1/2 inch / 65mm Dry Diamond Core Drill Bit with SDS Plus Adapter, Concrete Core Drill Bit for Dry/Wet Drilling Granite Marble Masonry Concrete Brick Stone and Block (65mm (2-1/2 inch)) - Image 3](https://m.media-amazon.com/images/I/61Qnxk4kqSL.jpg) ![- 2-1/2 inch / 65mm Dry Diamond Core Drill Bit with SDS Plus Adapter, Concrete Core Drill Bit for Dry/Wet Drilling Granite Marble Masonry Concrete Brick Stone and Block (65mm (2-1/2 inch)) - Image 4](https://m.media-amazon.com/images/I/71JQat9bT+L.jpg) ![- 2-1/2 inch / 65mm Dry Diamond Core Drill Bit with SDS Plus Adapter, Concrete Core Drill Bit for Dry/Wet Drilling Granite Marble Masonry Concrete Brick Stone and Block (65mm (2-1/2 inch)) - Image 5](https://m.media-amazon.com/images/I/81G9QTjMEgL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Delivered on time *by A***R on March 26, 2026* Strong and does work as expected ### ⭐⭐⭐⭐⭐ Good addition to my SDS-plus bit selection *by D***S on November 30, 2025* bought this for cutting drop rod holes for double drive gates.

After only cutting for about 3 min i noticed it easily binding in the hole. Pulled it out and two of the five teeth had broken off. I only had a short distance to go to get through one side of the block. I managed tho get through with three teeth. Mind you that if I got even slightly off perpendicular it would bind and rip my drill out of my hand. I drilled a pot hole through the outer side of the block and tried as carefully as possible to cut the remaining outer side of the block. Going very slowly. About one quarter of the way through it bound again. I pulled out the blade an a third tooth was gone. This ended my use of the blade and finished the hole with a hammer and chisel. Fortunately the pipe being installed through the hole had a large decorative cover to hide the chisel mess. --- ## 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.uk/products/805910595-2-1-2-inch-65mm-dry-diamond-core-drill-bit](https://www.desertcart.co.uk/products/805910595-2-1-2-inch-65mm-dry-diamond-core-drill-bit) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-04*
