SDS-PLUS drill bit Makita NEMESISII 12×315 mm

SDS-PLUS drill bit Makita NEMESISII 12×315 mm is designed for rotary and hammer drills with SDS-PLUS chucks and provides reliable performance when drilling into concrete, masonry and natural stone. With a diameter of 12 mm and an overall length of 315 mm, this drill bit enables deep, accurate holes for anchor fixing and through-drilling tasks. The flute geometry and carbide tip construction ensure efficient chip evacuation and long tool life under repetitive use.

Advantages

The Makita NEMESISII 12×315 mm offers stable drilling with consistent hole diameter and reduced wander at the start of the hole. Its carbide-tipped head resists wear and maintains cutting efficiency in abrasive materials. The optimized flute profile improves dust and debris removal from the hole, which helps maintain drilling speed and reduces heat buildup. The standardized SDS-PLUS shank allows quick, secure mounting in compatible chucks and fast bit changes.

Suitable for

• Drilling anchor and fixing holes in concrete and hollow block
• Through-holes for conduit and piping installations
• Concrete renovation and retrofit work where deep holes are required
• General masonry drilling in natural stone and brick

Key specifications

• Shank type: SDS-PLUS compatible
• Diameter: 12 mm
• Overall length: 315 mm
• Tip material: carbide
• Flute design: optimized for chip evacuation
• Intended materials: concrete, masonry, natural stone

How to use

Install the SDS-PLUS drill bit into the drill's SDS-PLUS chuck until it locks in place. Select the hammer or rotary-hammer mode appropriate for the material; use hammering action for concrete and masonry. Start drilling at low speed to position the bit, then increase speed and steady pressure as the drill progresses. Withdraw the bit periodically to clear dust and debris and to prevent overheating. After completing the hole, remove the bit by retracting it from the chuck according to the tool manufacturer's instructions.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. For best results, match drill speed and impact settings to the material and use cooling pauses during extended drilling. Inspect the carbide tip regularly and replace the bit when wear affects drilling performance or hole accuracy.
