A 6-piece SDS+ drill bit set covering the sizes you actually reach for on site. BC20 tungsten carbide tips, nickel chromoly shanks, and PGM-approved German testing. Sized for standard plastic plugs and masonry fixings.
This SDS+ drill bit set is the kind of thing that earns its place in the bag quickly. Six bits covering the sizes most commonly used for plastic plug and masonry fixing work — nothing redundant in there, no 3mm bit you’ll never touch. It’s a sds drill bit set built around what actually gets used on site, and the specs back that up.
The tips are BC20 tungsten carbide, which is a harder grade than what you’ll find in budget sets. Harder tip means it stays sharp longer in concrete and dense blockwork, which matters if you’re putting in a run of fixings rather than just the odd hole. The shanks are nickel chromoly steel, fully heat treated to keep them straight under load. Bent shanks are one of those small but genuinely annoying problems — worth avoiding.
Twin flute design pulls debris out of the hole as you drill, keeping the bit cooler and reducing the chances of binding. Cold formed blanks are used up to 11mm diameter, which improves the structural consistency of the bit compared to machined alternatives at this price point. They’re also shot-peened after forming, which increases surface hardness and fatigue resistance.
What’s in the SDS+ Drill Bit Set
The six sizes are selected for plug and fixing work across standard wall and masonry applications. Three shorter 110mm bits handle the 5.0, 5.5, and 7.0mm diameters for general plug sizes. The three 160mm bits cover 6.0, 8.0, and 10.0mm for deeper fixings into thicker masonry or where you need a bit more reach. German tested and PGM approved — which means independently verified performance standards, not just a badge on the packaging.
At this price, it’s a sensible set to keep as a site spare or to equip a new starter without spending serious money.
Pro Tip: When drilling into old lime mortar or softer masonry, drop your hammer setting to rotation-only first to avoid the face blowing out around the hole.
This SDS+ drill bit set is used daily by electricians, plumbers, general builders, and fixers drilling into brick, concrete, breeze block, and dense masonry. The size range suits rawlplug and plastic anchor installation at the most common fixing diameters. It's equally at home on a domestic job fitting shelving brackets as it is on a commercial site running cable containment fixings through a blockwork wall.
Not suitable for: Not suitable for use in standard drill chucks — these are SDS+ shank bits and require an SDS+ rotary hammer drill. Not designed for drilling timber, steel, or ceramic tiles.
Fit the bit into your SDS+ chuck with the hammer action engaged for concrete and masonry. Let the drill do the work — excessive downward pressure won't speed things up and will shorten the bit's life. Keep the drill as perpendicular to the surface as you can to avoid side-loading the tip.
For deeper holes with the 160mm bits, withdraw the bit periodically to clear debris from the flutes. In harder concrete, a drop of water on the tip helps with heat management on extended drilling runs.
Check the SDS+ chuck is clean and free of debris before fitting the bit
Insert the bit fully into the chuck and confirm it locks in with a slight pull
Select hammer-drill mode on your rotary hammer for concrete and masonry
Mark your depth on the bit with tape if drilling to a specific depth
Apply steady, moderate pressure and let the hammer action do the work
Withdraw the bit occasionally on deeper holes to clear dust from the flutes
Allow the bit to cool between extended drilling runs in hard concrete
Will these bits fit my SDS+ hammer drill?
Yes, provided your drill has an SDS+ chuck — which covers the vast majority of rotary hammer drills on the market. These bits will not fit a standard keyed or keyless drill chuck, or an older SDS (non-plus) machine.
What plug sizes do these bits suit?
The set covers 5mm, 5.5mm, 6mm, 7mm, 8mm, and 10mm diameters, which match the most commonly used plastic wall plug sizes from standard brown and red plugs up to the larger yellow and brown anchors. Check your plug packaging for the recommended drill diameter.
Are these bits suitable for reinforced concrete?
They will drill standard concrete and blockwork without issue. In heavily reinforced concrete where there is a chance of hitting rebar, a dedicated rebar-rated bit is a better choice. Hitting steel with a standard masonry tip will damage or break the carbide.
The bits use BC20 grade tungsten carbide inserts, a harder specification than standard carbide used in entry-level masonry bits. The body is nickel chromoly steel, heat treated through the full length to maintain straightness under hammer loading. Cold forming up to 11mm diameter preserves grain structure for better fatigue resistance. Shot-peening introduces compressive stress at the surface, reducing the risk of crack propagation under repeated impact. PGM approval indicates compliance with independent German performance testing standards.
