Abraboro SDS-Plus 4‑cut Concrete Drill Bit 7 mm x 210/150 mm

Abraboro SDS-Plus 4‑cut Concrete Drill Bit 7 mm x 210/150 mm is a rotary‑percussion masonry drill bit designed for use with SDS‑Plus hammer drills. With a 7 mm diameter, an overall length of 210 mm and a working length of 150 mm, the bit is optimized for drilling clean holes in concrete, brick and block. The four‑cut tip geometry enhances chip removal and improves drilling stability to reduce wandering and achieve more accurate hole placement.

Advantages

The four‑cut head provides improved centring and faster cutting in reinforced and non‑reinforced concrete compared with two‑cut tips. The SDS‑Plus shank ensures secure retention in compatible hammer drills and allows quick bit changes. The combination of overall and working length makes this bit suitable for common anchoring and conduit applications while maintaining rigidity for straight drilling.

Suitable for

• Drilling anchor holes in concrete and masonry
• Creating passages for electrical conduit and piping
• Installing fixtures, brackets and supports into walls and floors
• General rotary‑percussion drilling on construction and renovation sites

Key specifications

• Drill diameter: 7 mm
• Overall length: 210 mm
• Working (effective) length: 150 mm
• Shank type: SDS‑Plus
• Tip geometry: four‑cut head for improved chip evacuation
• Intended material: concrete, brick, masonry

How to use

Insert the SDS‑Plus shank into a compatible hammer drill and ensure the bit is locked in place. Select hammer‑drilling mode for concrete and apply moderate, consistent pressure while allowing the tool to do the work; avoid excessive force that can shorten bit life. Periodically withdraw the bit during extended drilling to clear debris and allow cooling. For through holes, drill from one side where possible or align and mark both faces before drilling to maintain accuracy.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Match drill speed and hammering force to the substrate hardness and monitor bit condition; replace the bit if the cutting edges become worn or the tip is damaged to maintain hole accuracy and worksite safety.
