Concrete SDS-Plus drill bit Abraboro 10×450/400 mm 4‑cut

Abraboro SDS-Plus concrete drill bit 10×450/400 mm 4‑cut is designed for drilling precise holes in concrete, masonry and natural stone with SDS-Plus rotary hammer drills. The bit combines a 10 mm diameter with a 450 mm overall length and a 400 mm working length to reach deeper installation points while maintaining stable guidance. Its 4‑cut multi-flute tip and flute geometry improve chip evacuation and reduce clogging during rotary and hammer drilling.

Advantages

The 4‑cut tip provides faster penetration and a more accurate hole profile compared with two‑cut designs, while the multi‑flute geometry accelerates dust and debris removal from the hole. The increased working length allows access to recessed or deep mounting points without extensions, and the SDS‑Plus shank offers secure fitting and quick bit changes in compatible rotary hammers. Materials and geometry are optimised for repeated use in concrete and masonry.

Suitable for

• Drilling anchor holes for fixing and fasteners in concrete and brick
• Creating passages for electrical conduits and plumbing in walls
• Installing dowels and threaded rods at medium depths
• General construction and renovation work requiring deep, narrow holes

Key specifications

• Shank type: SDS‑Plus compatible shank for rotary hammer drills
• Diameter: 10 mm
• Overall length: 450 mm
• Working (effective) length: 400 mm
• Tip design: 4‑cut multi‑flute carbide tip for improved chip removal
• Intended materials: concrete, masonry, natural stone

How to use

Securely insert the SDS‑Plus shank into the rotary hammer chuck until it locks. Select the hammer or rotary‑hammer drilling mode appropriate for concrete. Mark the drilling point, start at low speed to seat the tip, then increase to the recommended operating speed and apply steady axial pressure without forcing. Periodically withdraw the bit to clear accumulated dust and allow cooling when drilling deep holes. After use, remove dust from the flutes and store the bit in a dry place.

Usage recommendations

Use personal protective equipment including eye protection, hearing protection and a dust mask when drilling concrete. For reinforced concrete, verify location of rebar before drilling and avoid excessive side load to prevent tip damage. Replace the bit when wear reduces drilling performance or when the tip becomes visibly rounded or chipped.
