SDS Drill Bits – 450mm Long Budget Set – 3pc

This 3 piece 450mm SDS drill bit set gives you the three most commonly needed diameters in a single purchase — 12mm, 16mm and 24mm — all at the longer 450mm length that makes a real difference when you’re drilling through thick masonry or chasing a hole that a standard bit can’t quite finish. It’s the kind of set that earns its keep on a first fix day when you’re passing cables or pipes through a double-skin wall and realise your short bits are about six inches short of useful.

SDS Plus is the fitting of choice for most rotary hammer drills used in the trade, and these bits lock positively into the chuck without any faff. The 450mm working length means you can reach through dense blockwork, brick cavity walls, concrete lintels and similar construction materials without needing an extension. All three sizes are the sort of diameters that come up constantly on site — 12mm for cable and conduit routes, 16mm for bigger cables or fixings, and 24mm when you need a clean hole for a larger diameter pipe or sleeve.

Where This 450mm SDS Drill Bit Set Gets Used

These bits are suited to first and second fix work where wall thickness or depth makes shorter bits impractical. Think ground workers sleeving pipes through foundations, electricians running cable through block walls, plumbers routing pipework between rooms, or builders drilling for wall ties and fixings in solid masonry. The 450mm length also helps when you’re working at an awkward angle and need the extra reach to control the drill properly without fighting for position.

At this price point, it’s a budget set — the kind you keep in the van for general use rather than reaching for on a precision job where bit longevity is critical. For high-frequency drilling or abrasive aggregates, a premium carbide-tipped bit will outlast these. But for the occasional long reach job, or as a solid site spare, this 3 piece 450mm SDS drill bit set is hard to argue with.
