Cross-Tip Concrete Drill Bit 20x460 mm SDS Plus X-Tip YT-4225 YATO
SDS Plus cross-tip drill bit with a four-edge X-Tip head, designed for drilling into reinforced concrete, calcium silicate blocks and clay brick. The twin spiral ensures efficient debris removal, minimising the risk of jamming.
Technical features
X-Tip head with four cutting edges
The four-edge design increases the contact area with the material, which translates into faster drilling. On encountering reinforcement, the bit keeps working without the risk of damaging the tip – the edges distribute the load, minimising impact shocks.
Twin spiral for debris removal
Two spiral flutes effectively carry dust and fragments out of the hole while drilling. This prevents the flutes from clogging and the bit from jamming, particularly in deep holes in concrete.
40Cr steel body resistant to thermal expansion
40Cr chrome steel maintains dimensional stability as the temperature rises during intensive drilling. This eliminates the risk of the shank expanding and seizing in the SDS Plus chuck – the bit can be changed quickly even after prolonged work.
YG-11C carbide cutting head
YG-11C sintered carbide is characterised by high hardness and wear resistance. This material withstands contact with aggregate, reinforcement and hard aggregates in concrete, keeping the cutting edges sharp for longer.

Applications
- Drilling fixing holes in reinforced concrete for installing chemical and mechanical anchors
- Creating service penetrations in reinforced concrete walls and floor slabs
- Preparing holes for ventilation and air conditioning systems in concrete structures
- Drilling into calcium silicate blocks when running electrical installations
- Fitting façade elements into solid and perforated clay brick
- Renovation work in older buildings with high-aggregate concrete
- Installing earthing and lightning protection systems in concrete foundations
- Preparing holes for drainage and water supply pipes in structural walls
Tool compatibility
The SDS Plus shank is standard on rotary hammers and hammer drills weighing up to 5 kg. Before starting work, check that the drill supports hammer drilling mode – a cross-tip bit requires both rotation and axial impact for efficient drilling in concrete.
Use and maintenance
Before drilling, clean any dirt from the drill bit shank and apply a thin layer of graphite grease to the SDS Plus grooves. This ensures smooth seating in the chuck and easy removal once the work is finished.
When drilling, pauses of 30-40 seconds are recommended, particularly for holes deeper than 200 mm. This allows the tip to cool and the debris to clear. Excessive heating of the carbide can lead to micro-cracks and shorten the life of the bit.
After use, clean the bit with compressed air or a brush, removing concrete dust from the spiral flutes. Storing it in a dry place prevents corrosion of the steel body.
