Drilling into plain concrete is straightforward. Drilling into reinforced concrete — the kind found in virtually every structural element built in the last century — is a...

When a standard SDS-plus bit hits its limit at around 16 or 20 mm in diameter, and the job calls for a 22 mm hole through reinforced concrete — for a heavy-duty anchor bolt, a...

When you need to drill a hole 51 mm in diameter through a solid concrete wall, a standard twist drill bit is not an option — the forces would destroy the bit and the hammer too....

There is a point where SDS-Plus reaches its limit and the job demands the step up to SDS-Max. When you are drilling 25 millimetre and larger holes for heavy structural anchors,...

When standard-length bits bottom out before they reach the far side of a thick foundation wall, structural column, or multi-layer masonry construction, a long-reach SDS-max bit is...

When the hole diameter climbs past 30 mm — beyond the reach of any SDS-plus system — you are firmly in SDS-max territory. A 35 mm hole through reinforced concrete is not a casual...

When a standard SDS-plus drill bit tops out at around 16 mm and the job demands a clean, straight hole through reinforced concrete for anchor bolts, rebar dowels, or pipe sleeves,...

When the job calls for drilling into reinforced concrete, solid stone, or dense masonry, a standard drill bit simply will not do. You need something built to withstand punishing...

Some anchor holes need to go deep — through thick foundation slabs, beneath multiple layers of screed and insulation, or through structural beams where the anchor must reach well...

When you are anchoring structural steel, installing heavy machinery, or bolting down racking systems, a standard SDS-Plus bit will only get you so far. Once you need holes beyond...

Some holes need to go deep. When you are anchoring into a concrete foundation that is half a metre thick, drilling through a retaining wall to install drainage, or setting long...

Most holes drilled into masonry are shallow — 30 to 80 millimetres for a wall plug, an anchor bolt, or a pipe clip. But occasionally, a job demands a hole that passes all the way...

When a structural engineer specifies M12 or M16 anchor bolts for a critical connection — a steel column base plate, a bridge bearing, a crane rail — the hole must be drilled deep...

Drilling into concrete, brick, or stone is a completely different challenge from boring through wood or metal. Standard twist bits simply cannot handle the hardness and...
