Concrete drill bit Abraboro SDS-Plus 14×450/400 mm, 4-flute (AB00004030)

Abraboro concrete drill bit SDS-Plus 14×450/400 mm with a 4-flute design is engineered for rotary and hammer drilling in concrete and masonry. The 14 mm cutting diameter and overall length of 450 mm (usable length 400 mm) offer reach for through and deep-hole applications, while the SDS-Plus shank ensures secure, quick-fit connection to compatible rotary hammers. The four-flute geometry improves dust evacuation and directional stability for more consistent drilling performance in reinforced and plain concrete.

Advantages

The 4-flute profile enhances removal of dust and debris from the hole, reducing friction and heat build-up during operation. SDS-Plus quick-fit mounting provides reliable power transfer and fast bit changes. The bit’s length and diameter are selected to balance breakout resistance, straightness and penetration rate, making it suitable for repeated drilling tasks in building and renovation work. The geometry supports stable rotation and minimizes wandering when starting holes.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Creating anchor and dowel holes for fastening systems
• Installing through-holes for plumbing and electrical conduits
• Professional construction and DIY renovation tasks with SDS-Plus hammers

Key specifications

• Cutting diameter: 14 mm
• Total length: 450 mm
• Usable/working length: 400 mm
• Shank type: SDS-Plus
• Flute type: 4-flute cutting geometry for improved dust removal
• Application: concrete and masonry (rotary and hammer drilling)

How to use

Fit the drill bit into an SDS-Plus rotary hammer until it locks securely. Select an appropriate drilling mode—hammer drilling for concrete and rotary-only for delicate masonry where impact could cause damage. Start drilling at low speed to establish the position, then apply steady pressure and increase speed as the bit engages. Periodically withdraw the bit to clear accumulated dust and allow the flutes to evacuate debris. Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask or extraction when working in enclosed spaces.

Usage recommendations

For best results when drilling deep or reinforced concrete, use hammer mode with intermittent withdrawal to clear debris. Match the drill bit diameter to anchor and fastening specifications, and ensure the rotary hammer is rated for the bit length and drilling depth to maintain stable, safe operation.
