An SDS rebar cutter is a specialist tool for one job and it does that job well: drilling clean through reinforcing bar that’s already set in concrete. No burning through, no grinding, no wishing you’d planned the penetration before the pour. These one-piece cutters take a standard SDS Plus shank and get to work on embedded rebar with tungsten carbide tips that are built to cope with hardened steel rather than just concrete.
Available in diameters from 10mm right up to 32mm, all at 300mm length, there’s a size to suit most situations where rebar is the obstacle between you and a clean hole. The one-piece construction keeps things simple. No moving parts to wear out or fail under load, which matters when you’re pushing the cutter through steel and concrete simultaneously.
What Makes These SDS Rebar Cutters Worth Using
The tungsten carbide tips are heat treated for better tool life, which is exactly what you want given the punishment rebar puts on a cutting edge. Softer tips would blunt fast and leave you chasing the hole rather than finishing it. The slot cut into the body is a useful practical touch — it lets steel slugs clear from the cut zone without you having to stop and pick the bore out with something improvised. Keeps the cut moving, keeps the tip cooler.
The SDS Plus fitment is standard, so these drop straight into any compatible hammer drill without adaptors or faff. Quick change, quick back to work. That’s the kind of thing that matters when you’re on site and time is running.
One Rule Worth Repeating
Rotary mode only. This cannot be overstated. Running an SDS rebar cutter with the hammer action engaged will destroy the tool. The hammering action is not compatible with cutting steel — it’s designed for concrete alone. Switch the drill to pure rotary before you start, and keep it there throughout. It takes two seconds and saves you buying another cutter.
Pro Tip: Always keep a drop or two of cutting oil on the tip when working through thick rebar sections — it reduces heat buildup significantly and extends the life of the tungsten carbide edge.
SDS rebar cutters are used wherever concrete structures need new penetrations through existing reinforcement. That covers retrofit drainage, new service runs through reinforced slabs or walls, anchor bolt installations, and structural modifications on buildings where rebar is already in place. Civil engineering, groundworks, and structural refurbishment work all throw up situations where you need to cut rebar cleanly without disturbing the surrounding concrete.
They're also common on projects where design changes happen after the pour — not ideal, but it happens — and the only sensible solution is a clean drilled penetration straight through the bar.

Not suitable for: Not suitable for use with hammer action engaged. Do not use on materials other than steel reinforcing bar in concrete. These are not standard masonry drill bits and will not perform correctly if used as general-purpose drills.
Fit the cutter into your SDS Plus drill and confirm the drill is set to rotary mode only before you do anything else. Check it, then check it again. Apply light pressure to the concrete surface over the rebar location, then begin drilling at a moderate, steady speed. Let the tip do the work rather than forcing it.
As the cutter reaches the rebar, maintain consistent pressure without overloading the motor. The slot in the body will help clear steel slugs as the cut progresses. If you notice the tip getting very hot or the drill struggling, back off and allow things to cool before continuing. Once through the bar, you can complete the hole through the remaining concrete normally using the same cutter if the diameter is appropriate.
Confirm the drill is set to rotary mode only before fitting the cutter
Select the correct diameter cutter for the required hole size
Insert the SDS Plus shank into the drill chuck until it clicks and seats fully
Position the tip on the concrete surface directly over the rebar location
Begin drilling at a steady, moderate speed with consistent forward pressure
Allow the slug clearance slot to do its job — avoid excessive force if the cutter slows
If significant heat builds up, withdraw the cutter briefly and allow it to cool
Continue through the rebar and complete the penetration through remaining concrete
Can I use these SDS rebar cutters with the hammer function switched on?
No. Rotary mode only, without exception. Using the hammer action while cutting rebar will cause serious damage to the cutter and likely to the drill itself. The hammering motion is designed for concrete, not steel. Switch to pure rotary before you start, and leave it there until the job is done.
What size SDS rebar cutter do I need?
Match the cutter diameter to the hole size you need, not necessarily the rebar diameter itself. If you're creating a penetration for a service run, work from the required finished hole size. Sizes run from 10mm to 32mm, so most common rebar diameters and clearance requirements are covered across the range.
These one-piece SDS rebar cutters use a heat-treated steel body with heavy duty tungsten carbide tips, chosen specifically for cutting hardened steel reinforcing bar embedded in concrete. The one-piece body removes any jointed weak points and the integrated slug clearance slot helps evacuate steel material from the cutting zone during use. The SDS Plus shank conforms to standard fitment dimensions for universal compatibility with SDS Plus hammer drills.
