SDS-PLUS drill bit Makita NEMESISII 12 x 455 mm E-14576

SDS-PLUS drill bit Makita NEMESISII 12 x 455 mm E-14576 is a long masonry bit engineered for use with SDS-PLUS rotary hammers. With a 12 mm diameter and a 455 mm overall length, the bit provides extended reach for drilling through concrete, brick and natural stone. The design ensures stable retention in SDS-PLUS chucks and consistent drilling performance for installation tasks that require deep or pass-through holes.

Advantages

The solid carbide tip and flute geometry are optimized for masonry materials, reducing breakouts and promoting chip evacuation during deep drilling. The long shank and balanced construction minimize runout and vibration, improving hole accuracy. Compatibility with SDS-PLUS systems ensures quick bit changes and secure locking during heavy-duty or repetitive work.

Suitable for

• Drilling deep holes in concrete for anchor bolts and through-fixing
• Creating passages through brick and block walls for installations
• Drilling into natural stone for mounting or repair work
• Renovation and construction tasks requiring extended reach

Key specifications

• Shank type: SDS-PLUS compatible
• Diameter: 12 mm
• Total length: 455 mm
• Intended material: concrete, brick, stone
• Tip material: carbide cutting head for masonry
• Design: straight flute for chip removal and cooling

How to use

Fit the drill bit into the SDS-PLUS chuck until it locks securely. Use a rotary hammer set to the hammer-drill mode appropriate for masonry. Start drilling at low speed to position the tip, then apply steady pressure and maintain full hammer action. Periodically withdraw the bit to clear dust and chips, especially when drilling deep holes, to prevent overheating and maintain cutting efficiency.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Select a drill speed and hammer power suitable for the material and bit diameter. For precise depth control, use a depth stop or tape on the bit. Inspect the bit before use for wear or damage and replace if the carbide tip is chipped or dull.
