Rebar Cutters & Full-Carbide Rebar Bits
Two answers to steel in the hole. A rotation-only rebar cutter chews through the bar your hammer bit cannot pass — a full-carbide-head rebar bit never stops for it in the first place. Both SDS-Plus, both factory-direct.
Product Series
One problem, two duty profiles. Where bars are hit on hole after hole in Ø4–25 mm, a full-carbide bit drills straight through without a tool change. Where crews run brazed bits and meet steel now and then, where the bar is heavy, or where the hole is larger than Ø25 mm, a same-diameter rotation-only cutter passes the bar cleanly and saves the hammer bit.
SDS-Plus Rebar Cutter (Rotation-Only)
A hollow crown with sharp-ground brazed tungsten-carbide teeth, run with the hammer action switched OFF. When a hammer bit refuses on embedded bar, swap in the cutter at the same nominal diameter, cut through the steel, then swap back and finish the hole on line — no abandoned holes, no relocated anchors. The same crown family trades under two names — 'rebar cutter' at Bosch and Milwaukee, 'rebar breaker' at Heller and across OEM trade listings.
Full-Carbide Head Rebar Bit (Hammer-Mode)
A one-piece sintered solid-carbide head, resistance-friction-welded to the steel body. This is the hammer-mode lane retail knows from Diablo's Rebar Demon and Bosch's EXPERT SDS plus-7X — and the only rebar answer that never asks for a tool change: it drills reinforced concrete and the bar inside it in normal hammer mode, start to finish.

Crown or Carbide Head — and How Not to Kill Either
Most dead rebar cutters die the same way: hammer action left on. These fundamentals decide tool life and whether the hole survives the steel.
Pick the line by frequency
Bars on most holes, Ø4–25 mm → full-carbide bit, one tool straight through. Occasional strikes with brazed bits, heavy bar, or holes above Ø25 mm → hammer bit paired with a same-diameter rotation-only cutter.
Tip · Distributors stock both: full-carbide bits for rebar-dense programs, crowns for the holes that must pass heavy bar.
Rotation only means rotation only
Switch the hammer action OFF before the cutter touches steel — impact shears sharp-ground teeth in seconds. Moderate RPM, steady feed, let the teeth cut.
Tip · If the machine has no rotation-only mode, do not use a rebar cutter in it.
The swap workflow
Drill with the hammer bit until it refuses on steel. Swap to the same-diameter cutter, cut through the bar, swap back, finish the hole. The hole stays on line and on gauge.
Tip · Mark the depth on the cutter before you swap — you only need to pass the bar.
Clear the steel slugs
Steel chips and slug pieces must leave the crown. Peck and retract so the debris slots can do their work — packed steel in the crown stalls the cut and overheats the teeth.
Tip · Pull back every few seconds of steel contact; clear the bore before resuming.
Manage heat in the steel
Cutting rebar is metal cutting, dry. Use peck cycles and short pauses instead of leaning on the tool — discolored, blued teeth have already lost their edge hardness.
Tip · Smoke or blue chips mean too much speed or too much dwell. Back off.

Frequently Asked Questions
What is an SDS-Plus rebar cutter and when do I actually need one?
A rebar cutter is a hollow, multi-tooth carbide crown on an SDS-Plus shank, used in rotation-only mode to cut through steel reinforcement that a masonry hammer bit cannot pass. You need one when the hole position is fixed — doweling, anchor layouts, through-holes — and relocating the hole to dodge the bar is not an option.
Why must a rebar cutter run in rotation-only mode?
Its teeth are sharp-ground metal-cutting edges, not impact-rated masonry tips. Hammer action chips or shears them in seconds. Switch the hammer mechanism off, run moderate RPM with steady feed, and the crown cuts through the bar cleanly. This is the single most common cause of dead rebar cutters.
Is the Heller Rebar Breaker the same thing as a rebar cutter — and where does the full-carbide bit fit?
Three answers to one problem, two of them swap-in. A rebar cutter is a rotation-only crown you swap in to cut through the bar, then swap out. Heller's Rebar Breaker is the same swap-in idea built tougher: a one-piece-steel crown (Ø12–35mm; solid four-edge carbide up to 14mm, multi-edge crown above) that per Heller and its distributors runs with hammer action engaged — no mode discipline to forget, but the workflow is still drill, clear the hole, pass the bar, swap back. Our full-carbide-head line is the only one of the three that skips the swap entirely: one bit drills the concrete and the bar in hammer mode, start to finish.
Can a normal hammer drill bit go through rebar?
A standard two-cutter brazed hammer bit is not a rebar-cutting tool; it can chip or jam on steel. A reinforced-concrete four-cutter is designed to tolerate incidental contact, not to intentionally cut structural bar. If the fixed hole position requires bar cutting, obtain structural approval and use the specified dedicated rotation-only rebar cutter or approved full-carbide rebar bit with the correct machine and mode. For thick bar, the rotation-only cutter gives the more controlled cut.
What diameter rebar cutter should I use?
Use the same nominal diameter as the prepared hole. This defines the hole to be completed, not a universal maximum rebar size. Bar diameter, crossing position, steel conditions and the selected tool/machine limits are confirmed for the job.
Will your rebar cutters fit my rotary hammer?
Use a matching SDS-Plus rotary hammer with rotation-only mode and capacity suitable for the selected cutter. For SDS-Max, confirm the exact adapter, machine modes and impact-transmission design. An interface adapter alone does not authorize hammer use with our rotation-only crown.
Can distributors order rebar cutters in bulk under a private label?
Yes. We supply wholesale SDS-Plus rebar cutters and the separate full-carbide drilling line with your brand and packaging. Define diameters, working and overall lengths, quantities and pack format for the order. Crown cutters carry rotation-only instructions; full-carbide bits retain their own specified mode. MOQ and delivery are confirmed for the selected programme. We supply against normal purchase orders and do not offer a separate sample service.
Is it acceptable to cut rebar when drilling — does it compromise the structure?
That is an engineering decision, not a tooling one. On structural members, cutting reinforcement should be approved by the project engineer — scanning first and adjusting layout where possible. What the right tool changes is the quality of the outcome when cutting is approved: a clean cut hole on line, instead of a wandered hole and a destroyed bit.
