Review: Does the job at a reasoble price - 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 hole So 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. Review: Does the job drilling an awkward size through brick - If you need to drill a hole up to say 16mm then there are perfectly good conventional masonry bits available in a variety of lengths. If you want to go from 38mm upwards then there are some really good diamond core drilling sets. In this middle ground there is not much to choose from, which as I needed to drill holes through 9 inch brickwork to run cable conduit was a problem for me. This bit did the job. I used it slowly and it drilled cleanly on the outside, but did give some breakout on the inside. The only slight problem was clearing bits of the core which stuck in the bit and took some careful wiggling to remove them. I see another reviewer has not recommended this as up to the job for concrete which is a shame as it is listed for this. The listing does though say this is only suitable for DIY use, and I think that is fair - it is worth the cost if you will only need it once in a while; if you need to drill these size cores everyday then look elsewhere (and be prepared to pay a lot more). One correction on the listing - it says this goes with the silverline pilot drill and arbour; it does not - neither are needed as this is a standalone item. Despite the lack of a guide drill it was not difficult to get a clean start to the holes. ## Features - Warning:Only for domestic use - Heavy duty steel body with diamond dust cutting segments - Dry cutting of accurate holes in masonry - For use with 1/2" BSP compatible arbors - For use with drills equipped with a safety clutch - Do not use with ha mmer action ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000LFYX9S | | Best Sellers Rank | 179,261 in DIY & Tools ( See Top 100 in DIY & Tools ) 117 in Core Drill Bits | | Brand | Silverline | | Customer Reviews | 4.3 out of 5 stars 1,151 Reviews | | Cutting Angle String | 9E+1 Degrees | | Cutting Diameter | 150 Millimetres | | Cutting angle string | 9E+1 Degrees | | Cutting diameter | 150 Millimetres | | EU Spare Part Availability Duration | 1 Years | | Finish Types | Painted | | Finish type | Painted | | Global Trade Identification Number | 05055058104366 | | Included Components | 1 x Diamond core drill bit 152 x 150mm | | Item Dimensions | 15.2 x 15.2 x 0.1 centimetres | | Item Type Name | tools | | Item Weight | 2.46 Kilograms | | Manufacturer | SLTL4 | | Material | Alloy Steel , Diamond | | Model Number | 406549 | | Number of Flutes | 2 | | Point Style | Diamond Point | | Shank Type | SDS-Top | | Shank type | SDS-Top | | Surface Recommendation | masonry | | Tool Flute Type | Spiral | | UPC | 002147483647 | | Unit Count | 1.0 count | ## Product Details - **Cutting angle string:** 9E+1 Degrees - **Cutting diameter:** 150 Millimetres - **Finish type:** Painted - **Material:** Alloy Steel, Diamond - **Shank type:** SDS-Top ## Images ![Silverline 406549 Diamond Core Drill Bit 152 x 150 mm, Blue - Image 1](https://m.media-amazon.com/images/I/515S6wdk8FL.jpg) ![Silverline 406549 Diamond Core Drill Bit 152 x 150 mm, Blue - Image 2](https://m.media-amazon.com/images/I/41LVdwU73WL.jpg) ![Silverline 406549 Diamond Core Drill Bit 152 x 150 mm, Blue - Image 3](https://m.media-amazon.com/images/I/51WUJhGy+hL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does the job at a reasoble price *by G***F 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.
