The concrete blocks were about thirty years old and as hard as stone. It took a while but it all went well and I have no problem recommending this drill bit. There looks like there's plenty of cutting edge for a few more cuts so good value.I would say you will need a big SDS drill to spin this bit but you already knew that? ### ⭐⭐⭐⭐ 4.0 out of 5 stars Works well *by E***Y on Reviewed in the United Kingdom on 20 October 2013* I've used this to cut a couple of holes for extractor fans. It takes time and skill to use it, I can't seem to get the hole perfectly perpendicular to the wall, not sure if it's my lack of skill or the fact I need a more powerful drill. You need to be careful to position the core properly when drilling or it does jam, but it certainly works. Our brickwork is quite old so pretty hard, but it got thru it and is much neater than knocking out a brick with a hammer. Good value too, much cheaper than anywhere else I could find... ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Does the job at a reasoble price *by G***F on Reviewed in the United Kingdom on 16 December 2014* Had to put in some 100mm extractor fans, which needed holes cut through 12 inch thick brick and cinder block cavity walls. Got this 107 mm diameter by 150mm long core drill, as it was cheaper that getting someone in to do the job.I was lent a 110mm TCT Core Drill Bit, but that was too shallow to get through a course of brick in one go, so it needed a lot of extra chiselling.With this I was able to cut straight through the wall from one side in one go, occasionally stopping to remove debris, from inside the warm house, on a cold day.My SDS drill is not the best quality and struggled a bit with such a large cutter, sometimes causing the safety clutch to slip, but with care it worked ok.I bought this together with the "Silverline 124518 SDS Plus Core Drill Arbour 200mm" and "Silverline 769992 Morse Tapered Guide Drill Bit 8mm x 200mm".The instructions were in the tiniest writing I have ever seen, or could hardly see, part of which read as follows;Important notes* NEVER use hammer or impact action with diamond core drill bits;* this will damage the cutting edges, increase the risk of jamming and possibly bend longer arbours and arbour extensions* Core drill bits should only be used with drills with safety clutches, with the possible exception of small core drills* Core drills, arbours and extensions are heavy, and core drilling creates a large load for the motor of the power tool, even at low rpm. It is important to consider this when selecting a suitable power drill for the diameter and depth of the hole you wish to drill. It may be necessary to use the `stitch' drilling technique first and then finish with the core drill to make the final cut for the holeSo it was not until I finished and then scanned, enlarged and transcribed the instructions I able to read them and then realised I should not have used any hammer action with the SDS drill. However the cutter still seems in pretty good condition.The guide drill was a bit prone to falling out, particularly with the hammer action, so was firmly tapped into place and stayed in long enough for the core drill to get deep enough to guide itself. Otherwise it all worked ok for me and achieved what was needed at an acceptable cost. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/52590366-silverline-282415-diamond-core-drill-bit-42-x-150-mm](https://www.desertcart.tn/products/52590366-silverline-282415-diamond-core-drill-bit-42-x-150-mm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-24*
