Concrete, Brick & Rotary Hammer Drilling

Concrete doesn't care how quickly the next fixing needs to go in. Sutton SDS masonry drill bits give builders, electricians, plumbers, installers & construction crews purpose-built options for drilling concrete, brick & other compatible masonry with SDS rotary hammers. Across the Sutton masonry range, buyers can compare SDS Plus & SDS Max drill bits, 2-cut & 4-cut cutting heads, different diameters & working lengths to match the machine, substrate & hole being drilled.

Getting those details right matters before the rotary hammer starts. A bit can have the correct diameter yet still be wrong because the SDS shank doesn't match the machine, the working length won't reach the required depth or the cutting geometry isn't specified for the material ahead. Reinforced concrete deserves particular attention because selected Sutton 4-cut & Reo-specific products are designed for that application—not every SDS masonry bit should be treated as interchangeable.

For anchor holes, service penetrations & general masonry drilling, start with four practical checks: machine compatibility, masonry type, finished hole diameter & required working depth. Then compare head geometry & the individual Sutton product specification. That selection process helps avoid choosing an SDS bit from diameter alone while overlooking the conditions that actually determine whether it belongs on the job.

Already have the hole size in mind? Check  Hammer Drills for the machine side of the setup, or move into  Concrete Cutting & Drilling Tools when the work extends beyond individual SDS holes.

What Makes an SDS Masonry Drill Different?

The shank gives away half the story.

An SDS masonry drill is designed to work with a compatible SDS rotary hammer system, allowing the machine to deliver the rotary & hammering action required for suitable masonry drilling while retaining the bit through the SDS interface.

At the cutting end, carbide-based masonry geometry attacks the substrate. Behind it, the flute has another job entirely: move drilling debris away from the tip & out of the hole.

Both ends matter. A powerful rotary hammer with the wrong shank won't solve the problem, while the correct shank attached to the wrong masonry geometry won't magically make every substrate suitable.

SDS Plus or SDS Max? Check the Machine Before the Masonry

Buying by diameter first can lead straight to the wrong shank.

SDS Plus – Common Rotary Hammer Drilling

Sutton's SDS Plus masonry ranges are designed for SDS Plus rotary hammer drills.

That makes SDS Plus an important starting point for many fixing, installation & service-penetration jobs where the required hole diameter, depth & substrate sit within the selected bit's specifications.

The machine connection should be confirmed before anything else goes into the cart.

SDS Max – Larger Rotary Hammer Platform

SDS Max is a different interface.

Sutton's D676 Reo Pro range, for example, uses an SDS Max shank & is designed for SDS Max rotary hammer drills.

An SDS Plus bit doesn't become SDS Max because both names contain “SDS”. Match the shank to the chuck system.

What Are You Drilling Into Today?

A wall can look simple from three metres away. The material inside it may not be.

Concrete – Choose From the Actual Hole Requirement

Concrete drilling combines abrasive material with impact-driven cutting.

Start with the required finished diameter, then check how deep the anchor, fixing or penetration needs to extend. Sutton lists SDS masonry ranges specifically suitable for concrete, but capability varies between product families.

For repeated anchor holes, consistency in diameter & depth matters more than choosing the biggest rotary hammer available. The fixing specification should lead.

Brick & Blockwork – Don't Treat Every Masonry Unit Like Concrete

Brick, aerated concrete & masonry units behave differently under a hammering cutter.

Sutton's SDS Plus ranges include products specified for brick & aerated concrete alongside concrete, stone & granite. Even so, the condition of the material matters.

Older, brittle or hollow masonry can demand more care than dense new concrete, particularly when the finished hole will carry a fixing.

Reinforced Concrete – Reo Changes the Conversation

What happens when the bit stops meeting concrete & starts meeting steel?

Selected Sutton 4-cut SDS Plus products are specified for reinforced concrete, while Sutton's SDS Max Reo Pro range is specifically designed to drill through reinforced concrete mesh.

That does not mean every masonry SDS bit should be driven blindly through reinforcement.

Before drilling structural concrete, establish where services & reinforcement may be located & follow the requirements applying to the work. A drill bit is not permission to drill anywhere.

Stone & Granite – Check the Exact Sutton Range

Several Sutton SDS Plus families list stone & granite among their applications.

Hard masonry materials can still vary significantly, so use the individual bit's application guidance rather than assuming every carbide masonry cutter has identical capability.

The product specification wins the argument.

2-Cut vs 4-Cut SDS Bits – What's the Practical Difference?

Two bits can share a diameter without presenting the same cutting head to the concrete.

Don't reduce the decision to “four must be better than two”.

The useful question is whether the specific bit geometry is designed for the material & drilling condition in front of you.

Diameter Gets the Attention. Working Length Does the Quiet Work.

A 10mm bit is not fully specified by saying “10mm”.

Imagine drilling an anchor hole close to the surface. Now compare it with taking the same nominal diameter deep through a wall for a service penetration.

Same diameter. Completely different reach requirement.

Sutton publishes both overall & working/flute lengths across its SDS ranges. Its D614 210mm SDS Plus products, for example, use a 210mm overall length with 150mm working/flute length.

Read both dimensions. The chuck doesn't disappear when the drilling starts.

For marking drilling positions, levels & installation points before the first hole,  Measuring & Leveling Tools can support the layout stage.

Choose a Sutton SDS Masonry Bit in Five Decisions

Confirm SDS Plus or SDS Max

Look at the rotary hammer first. The shank system must match the machine.

Identify the Substrate

Concrete? Reinforced concrete? Brick? Aerated concrete? Stone?

The answer immediately changes which Sutton product families deserve consideration.

Set the Hole Diameter

Anchor, fixing, plug or service requirements should determine diameter.

Guessing here can compromise the installation after the drilling is finished.

Establish the Required Working Depth

Look beyond total bit length.

Determine how much usable drilling depth the application requires while allowing for the machine & installation conditions.

Compare Head Geometry

Once compatibility, material, diameter & depth are correct, compare suitable 2-cut, 4-cut or application-specific options.

That order prevents a feature from becoming more important than the job.

Dust Has to Leave Somewhere

Every millimetre of hole produces material that no longer belongs in the wall.

Sutton's D614 2-cut SDS Plus range uses a combination spiral flute designed to move drilling dust away from the tip, while the current 4-cut solid range uses progressive flute geometry for dust release.

That makes flute design part of drilling performance—not decoration spiralling around the steel.

During deeper drilling, debris has further to travel before it reaches the surface. Pay attention when evacuation changes.

For compatible supporting products around the drilling setup,  Drill Accessories provide a more relevant next step than treating the masonry bit as an isolated purchase.

Anchor Hole or Through-Hole? Decide Before Starting

These two jobs ask different things from the bit.

Anchor or fixing holes generally need the correct diameter & sufficient depth for the specified fixing system.

Through-holes add another variable: the bit has to reach the opposite side of the material.

That may require considerably more working length.

Before selecting a long SDS bit simply because it offers extra reach, consider whether the job actually needs it. Excess length can make handling more awkward when a shorter bit would comfortably complete the hole.

Reach should solve a problem.

Before Pulling the Trigger: The 30-Second Site Check

A rushed hole can create a much slower repair.

► Confirm the drilling location.
► Check for known or detectable services behind the surface.
► Consider reinforcement before drilling structural concrete.
► Verify SDS shank compatibility.
► Match bit diameter to the fixing or penetration.
► Confirm working length.
► Use appropriate PPE & dust controls for the material & task.
► Keep the drilling area controlled around other workers.

For construction-specific protection,  Protective Equipment For Concrete Work belongs naturally beside masonry drilling rather than being treated as an afterthought.

Expert Tips From the Hole Outwards

Let the fixing choose the diameter. An anchor system shouldn't have to compensate for a casually selected hole.

Check working length separately from overall length. Packaging can show a long bit while the usable drilling portion is shorter.

Don't force a stalled cutter blindly. Unexpected resistance can indicate a change in material or an obstruction worth investigating.

Keep the bit aligned. Starting straight helps keep the hole closer to its intended position & diameter.

Watch dust evacuation on deeper holes. Packed debris increases the difficulty of the drilling process.

Inspect the carbide head after demanding work. Damage at the cutting end changes what enters the next hole.

Match SDS to SDS. SDS Plus & SDS Max are distinct machine interfaces.

Treat reinforcement deliberately. Use a product specifically suited to reinforced concrete where that application is required.

Consider the substrate condition. Brittle brickwork & dense reinforced concrete should not automatically receive identical drilling treatment.

Know what is behind the surface. Electrical, plumbing & other concealed services turn careless drilling into a much bigger job.
