Good quality drill bit at a good price

Needed to run two shielded CAT6 cables through a 35cm thick external wall (plasterboard over concrete & brick). My trusty old Hilti SDS has died and rather than forking out £lol money for a replacement battery, I thought I'd spend a few quid and see if my Makita 18V drill would manage.With a little welly and set to hammer function, the 40cm drill bit went through both skins of the wall, leaving a clean 8mm hole - perfect for a single shielded ethernet cable.Also managed to drill through a 25cm thick concrete, load-bearing wall between the kids' bedrooms, so their consoles, PC & TVs now have wired connections to the upstairs Gigabit switch.We now have CAT6 cables pushing our Gigabit network throughout the house and to 4 external CCTV cameras, which has improved the kids' connection speeds & stability (no more complaints about high ping or drop outs over WiFi) and also takes the pressure off our wireless network.Very happy - decent result for a fraction of the cost of replacing an expensive Hilti SDS battery.

This masonry drill bit really ‘rocks’ my world! I’ve been ‘bored’ with other bits that claim to handle concrete or brick, but this one truly ‘cements’ its place as a top-tier tool. The ‘bit’ starts strong and doesn’t ‘wander,’ which I’m sure any DIY enthusiast would agree is critical.
