SDS-PLUS drill bit Makita NEMESISII 16 x 455 mm E-14772

Makita NEMESISII SDS-PLUS drill bit 16 x 455 mm is designed for drilling through concrete and natural stone with SDS-PLUS rotary hammers. The 16 mm diameter and 455 mm overall length allow creation of deep, precise holes for anchor bolts, through-holes for services and installation work. The bit fits SDS-PLUS chucks and is compatible with a wide range of rotary hammers used in building and renovation tasks.

Advantages

The hardened carbide tip and reinforced flute geometry provide improved penetration speed and prolonged tool life when drilling in reinforced concrete and masonry. The SDS-PLUS shank design ensures secure retention in the rotary hammer chuck and efficient transmission of hammering energy. Balanced construction reduces runout for straighter holes and more consistent results during repetitive work.

Suitable for

• Drilling anchor and fixing holes in concrete and stone
• Creating through-holes for pipes and electrical conduits in masonry
• Construction, renovation and installation work requiring deep holes
• Professional and trade applications using SDS-PLUS rotary hammers

Key specifications

• Tip material: carbide-tipped for hard materials
• Shank type: SDS-PLUS compatible
• Diameter: 16 mm
• Overall length: 455 mm
• Intended materials: concrete, reinforced concrete, natural stone, masonry
• Flute design: spiral flute for efficient debris extraction

How to use

Install the SDS-PLUS shank securely into the rotary hammer chuck and ensure the tool is set to the hammer drilling mode. Mark the drilling position and start at low speed to establish the hole, then increase power while maintaining a firm, controlled grip. Periodically withdraw the bit to clear dust and debris from the hole, which helps maintain drilling efficiency and reduces heat buildup. Use appropriate personal protective equipment, including eye and hearing protection, and follow the rotary hammer manufacturer’s safety instructions.

Usage recommendations

For best results when drilling deep holes, use steady pressure without forcing the bit, allow the hammer action to do the work, and clear debris regularly. Match the drill bit length and diameter to the anchor or sleeve specification to ensure a proper fit. When encountering reinforcement bars, slow down and switch to a suitable rebar-cutting accessory if needed.
