MAXTEC Rebar Cutter SDS Plus Drill Bit - TCT for Reinforced Concrete

MAXTEC Rebar Cutter SDS Plus Drill Bit

The MAXTEC Rebar Cutter SDS Plus Drill Bitis a specialised tool engineered for efficiently drilling through rebar embedded within concrete structures. Featuring a Tungsten Carbide Tipped (TCT) head, it offers exceptional durability and cutting precision, making it well-suited for heavy-duty construction tasks. Its annular design focuses cutting power directly on the rebar while minimizing impact on surrounding concrete, helping to preserve structural integrity. The cutter also includes relief and core holes that aid in debris removal during operation, reducing the risk of bit binding and ensuring a cleaner, more efficient drilling process. With an SDS Plus shank, it securely fits rotary hammer drills for fast, stable bit changes. Ideal solution for construction professionals needing to install anchors, conduits, or other components through reinforced concrete without damaging the surrounding area.

Why Choose the MAXTEC Rebar Cutter SDS Plus Drill Bit

• Annular TCT cutting head: The tungsten carbide tipped head is constructed to cut through hardened steel reinforcement, not deflect from it. The annular geometry focuses cutting force directly at the bore diameter, which reduces heat at the tip and distributes wear evenly across the full cutting circumference rather than concentrating it on a single point.

• Wide spiral flute: The wide helical flute carries metal swarf, concrete dust, and debris out of the bore continuously as the bit rotates. Clearing material from the hole during the cut is what prevents binding, reduces tip temperature, and extends usable life between replacements.

• Relief hole and core hole: Both features are machined into the cutting head to assist heat dissipation and swarf ejection. The relief hole reduces pressure build-up at the cutting face, and the core hole allows metal chips to escape laterally rather than packing into the bore and stalling the cut.

• SDS Plus shank: Fits all rotary hammer drills with an SDS Plus chuck with no key tightening required. Bit changes between the standard masonry bit and the rebar cutter are fast and secure, which matters when switching tools mid-hole on a live pour or tight programme.

• Ten stocked diameters: The range from 10mm to 32mm covers anchor installation, conduit and cable penetrations, through-bolt holes, and service runs through reinforced concrete walls, floors, and columns. Contractors can match the cutter diameter exactly to the masonry bit already in use.

• Preserves structural integrity around the bore: The annular cutting action removes only the material at the bore diameter. Surrounding concrete is not percussed, cracked, or spalled during the cut, which is critical on structural elements, bridge decks, and retaining walls where the concrete matrix must remain intact.

Frequently Asked Questions

Q: What is the difference between this bit and a standard SDS Plus masonry drill bit?

 A: A standard SDS Plus masonry bit is designed for percussive drilling through concrete and stone. It is not built to cut through steel reinforcement. When a masonry bit contacts embedded rebar, it will deflect off the bar, bind in the hole, or fracture the carbide tip. The MAXTEC Rebar Cutter SDS Plus Drill Bit uses an annular TCT cutting head specifically engineered to engage and cut through steel rebar in rotary mode. It is the correct tool to reach for once your masonry bit has reached a reinforcement bar.

Q: Why can this bit only be used in rotary mode and not hammer mode?

 A: The TCT teeth on this bit cut by rotating across the rebar surface, not by impact. Engaging hammer or percussion mode delivers rapid axial impacts to the cutting head. On contact with hardened steel reinforcement, that impact energy fractures the carbide teeth rather than cutting through the bar. Beyond destroying the bit, fractured carbide teeth can be ejected from the chuck at considerable speed. The drill must be confirmed in rotary-only mode before the rebar cutter is inserted, and that setting must not change until the bit is fully removed from the bore.

Q: Can I use this bit on plain concrete or masonry?

 A: No. This bit is rated for reinforced concrete only, meaning concrete with embedded rebar present. It is not suitable for plain concrete drilling or masonry. The cutting geometry is optimised for steel, not abrasive mineral material. Using it on plain concrete or masonry will wear the TCT teeth rapidly and provides no performance advantage over a correctly specified masonry bit. For plain concrete and masonry, use the appropriate SDS Plus masonry bit from the MAXTEC range.

Q: Which diameter should I order?

 A: The rebar cutter diameter must match exactly the diameter of the hole you are already drilling. If you are using a 16mm SDS masonry bit for the main bore, you need a 16mm rebar cutter. A smaller cutter cannot reach the rebar. A larger cutter cannot enter the existing bore. The MAXTEC Rebar Cutter SDS Plus Drill Bit is stocked in ten diameters: 10, 12, 14, 16, 18, 20, 22, 24, 25, and 32mm, covering the full range of anchor and fixing hole sizes in common use on UK construction sites.

Q: How do I know when the rebar has been fully cut through?

 A: Resistance drops noticeably and the bit advances freely into the bore once the bar is severed. If progress stalls before the rebar is through, withdraw the bit, clear debris from the flute, allow the tip to cool for a short interval, and re-enter the bore. Packing of metal swarf in a tight bore is the most common cause of stall on thicker rebar sections. Do not increase pressure or engage hammer mode to try to force through a stall.

Q: How long do the carbide teeth last?

 A: Tooth life depends on rebar grade, diameter, and the number of holes cut per session. TCT tips on correctly operated annular cutters cutting standard UK reinforcement bar (typically grade B500B) will cut multiple holes before showing significant wear. The most common causes of premature tooth loss are operating in hammer mode, misalignment during the cut, and running the bit hot through insufficient cooling intervals. Inspect the full tooth count after every use. Replace the bit at the first sign of a missing or chipped tooth: an incomplete cutting head is unbalanced and will damage remaining teeth rapidly.

Q: Is this bit compatible with all SDS Plus rotary hammer drills?

 A: Yes. The SDS Plus shank is a universal standard compatible with all rotary hammer drills that accept SDS Plus bits, including tools from Bosch, DeWalt, Makita, Hilti, Milwaukee, Metabo, and most other branded rotary hammers. No adaptor is required. Before purchasing, confirm that your drill has a clean rotary-only mode. A small number of older or budget rotary hammer drills do not offer a clearly defined rotary-only setting, which makes them unsuitable for use with any rebar cutter.

Q: What PPE is required when using this bit?

 A: Safety goggles rated to EN166 and cut-resistant gloves are the minimum requirement throughout operation. Metal swarf produced during rebar cutting is sharp and fast-moving, particularly on downward cuts where ejected material travels upward toward the operator. A dust mask rated to at least FFP2 is recommended in confined spaces or poorly ventilated areas where concrete dust and fine metal particles cannot disperse freely. Standard construction site PPE including safety footwear and a hard hat should be worn where site rules require it.

Q: Why must the bit enter the bore perfectly straight?

 A: The annular cutting head must remain concentric with the bore throughout the cut. If the drill is tilted, the TCT teeth on one side of the head make disproportionate contact with the rebar, concentrating wear on two or three teeth rather than distributing it across the full cutting circumference. This is the second most common cause of early tooth failure after incorrect drill mode. The alignment guidance supplied with the product illustrates correct straight entry compared to off-angle entry. If you cannot hold the drill straight by hand in a tight or awkward location, brace the drill body or use a guide.
