TCT Core Bits
Three dedicated series — SDS-Plus for brick and masonry, SDS-Max 2-Piece for reinforced concrete, SDS-Max One-Piece for precision high-frequency work. Each matched to the material and the machine.
Product Series
One series cannot serve all substrates. Brick needs different geometry and carbide than reinforced concrete. An integral shank performs differently from a modular adapter under daily production loads. Choose the series built for your material and your volume.
SDS Plus/Max TCT Core Bit
One replaceable-pilot core-bit family in two shanks: SDS-Plus for brick, hollow block and AAC, SDS-Max for full-energy drilling through reinforced concrete. Brazed carbide teeth, helical chip evacuation, and a pilot drill you replace on its own instead of scrapping the assembly.
SDS-Max TCT Core Bit (One-Piece)
One-piece forged body — SDS-Max shank machined directly into the barrel, no adapter joint to loosen. Cleaner holes and lower operator fatigue on high-volume sites.

Frequently Asked Questions
Which series should I choose — SDS-Plus, SDS-Max 2-Piece, or SDS-Max One-Piece?
Use three criteria: (1) Wall material — brick, block, or aerated concrete → SDS-Plus; reinforced concrete or dense masonry → either SDS-Max series. (2) Machine — standard rotary hammer → SDS-Plus; SDS-Max hammer drill → either SDS-Max series. (3) Volume and precision — occasional large-diameter penetrations where component replaceability matters → SDS-Max 2-Piece (replace only the worn pilot drill); daily high-volume or precision-fit work where wobble causes problems → SDS-Max One-Piece (one-piece, zero joint play, less fatigue).
What is the difference between the SDS-Max 2-Piece and SDS-Max One-Piece?
Both are SDS-Max and both cut concrete. The 2-Piece is an assembly system: pilot drill, adapter, and barrel are separate components. This is useful because when the pilot drill wears out, you replace only that part — not the full assembly. The One-Piece is a single forged body with the SDS-Max shank machined directly into the barrel: no joints, no play, higher concentricity, measurably less vibration. One-Piece suits high-volume professional sites where hole roundness and operator fatigue matter. 2-Piece suits occasional large-diameter work and buyers who prefer field-replaceable components.
Can these cut through reinforced concrete with rebar?
The SDS-Max 2-Piece and SDS-Max One-Piece series are rated for reinforced concrete. YG11C carbide teeth are selected for their impact toughness when the tool contacts steel rebar. The SDS-Plus series is optimized for brick and AAC — it will cut light concrete but is not designed for steel rebar contact and will wear prematurely.
Is the pilot drill replaceable?
Yes in the SDS-Plus and SDS-Max 2-Piece series — the pilot drill is a standard SDS-Plus bit supplied as a separate replaceable component. In the SDS-Max One-Piece series, the pilot tip is part of the forged integral body and is not a separate replaceable item — the integral one-piece design is specifically what distinguishes that series.
What applications are TCT core bits used for?
Primary MEP applications: HVAC sleeve penetrations (air-conditioning unit mounting, duct routing), electrical conduit entry points through masonry or concrete, plumbing pipe passages, cable tray routing through partition walls, and fire-stopping sleeve installations. The specific series depends on the wall substrate — see the series comparison above.
What diameter range do your TCT core bits cover?
Ø30–160mm across the full range. SDS-Plus covers Ø30–160mm in masonry. SDS-Max 2-Piece covers Ø68–160mm for large penetrations in concrete. SDS-Max One-Piece covers Ø30–65mm for precision high-frequency applications. Custom diameters available on OEM orders.
What is the working depth range?
Working depth by series: SDS-Plus 70–150mm for standard partition walls; SDS-Max 2-Piece up to 300mm for thick structural walls; SDS-Max One-Piece 70–150mm for typical wall thicknesses. Custom working depths can be specified on OEM orders.
Do you offer OEM TCT core bit supply?
Yes. OEM options include custom diameter and depth configurations across all three series, carbide grade selection, custom shank adapters, laser engraving, and full retail packaging design. Contact us with your specification requirements and destination market.
