SDS-PLUS drill bit Makita NEMESISII 12x215 mm E-14548

SDS-PLUS drill bit Makita NEMESISII 12x215 mm E-14548 is a carbide-tipped rotary hammer bit intended for use with SDS-PLUS shank rotary hammers. With a 12 mm diameter and 215 mm total length, the design balances drilling speed and control for concrete, masonry and natural stone. The flute geometry and carbide tip support reliable chip evacuation and consistent hole dimensions during repetitive drilling tasks in construction and renovation settings.

Advantages

The Makita NEMESISII 12x215 mm drill bit offers strong wear resistance from a hardened carbide tip and a precisely ground flute profile that improves dust and debris removal. Its SDS-PLUS shank ensures secure retention in compatible rotary hammers and enables quick bit changes. The combination of tip geometry and shaft rigidity helps maintain hole accuracy and reduces wandering when starting holes in hard materials.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Creating passage holes in masonry walls
• Installing electrical boxes and conduits in stone or brick
• Renovation work requiring repeated, consistent drilling in hard substrates

Key specifications

• Shank type: SDS-PLUS compatible
• Tip material: carbide-tipped cutting head
• Diameter: 12 mm
• Total length: 215 mm
• Suitable materials: concrete, masonry, natural stone
• Flute design: optimized for chip removal

How to use

Select a rotary hammer with SDS-PLUS chuck compatible with a 12 mm bit. Mark the drilling point and, where possible, start at low speed to position the tip precisely before applying full hammer action. Insert the SDS-PLUS shank fully into the tool chuck until it locks. Use steady pressure without forcing the bit; allow the hammer action and carbide tip to penetrate the material. Withdraw the bit periodically for clearing dust and to prevent overheating when drilling deep holes. After use, clean the flute and tip of dust before storage.

Usage recommendations

Use appropriate personal protective equipment including eye and hearing protection and a dust mask when drilling. Match the drill mode and speed to the material: rotary hammer mode with hammering action for concrete and masonry. For best life and performance, avoid excessive lateral force and remove dust from the hole and bit regularly during prolonged drilling sessions.
