SDS-PLUS drill bit Makita NEMESISII 14 x 315 mm, model E-14663

SDS-PLUS drill bit Makita NEMESISII 14 x 315 mm is a carbide-tipped masonry bit designed for use with SDS-PLUS hammer and rotary-hammer drills. With a 14 mm cutting diameter and 315 mm overall length, this bit enables deep drilling in concrete, brick and natural stone while maintaining stable drilling performance. The SDS-PLUS shank offers secure engagement in compatible chucks and allows fast tool-free bit changes for continuous work on construction and renovation sites.

Advantages

The Makita NEMESISII bit combines a reinforced carbide tip and precision flute geometry to deliver consistent hole quality and extended service life when used in hammer drilling applications. Its 315 mm length allows access to deeper anchor points and through-holes without sacrificing bit straightness, while the SDS-PLUS connection minimizes slippage and improves impact energy transfer. The bit's balanced design reduces vibration and helps maintain drilling speed under load.

Suitable for

• Drilling holes in reinforced and non-reinforced concrete for anchors and dowels
• Creating passage holes through brick and block walls
• Installing electrical boxes, pipes and HVAC fixtures requiring deep holes
• Renovation and repair work where repeatable, reliable hole dimensions are needed

Key specifications

• Cutting diameter: 14 mm
• Total length: 315 mm
• Shank type: SDS-PLUS
• Tip material: carbide
• Intended materials: concrete, masonry, natural stone

How to use

Install the SDS-PLUS drill bit into a compatible SDS-PLUS hammer or rotary-hammer drill until it locks. Select the hammer-drilling mode for concrete and masonry operations. Start drilling at low speed to establish the initial position, then apply steady pressure and allow the tool's impact action to drive the bit. Clear dust frequently from deep holes by withdrawing the bit periodically to maintain drilling efficiency and avoid bit overheating. Replace the bit if the carbide tip becomes blunt or the bit shows signs of excessive wear.

Usage recommendations

For best results use with a hammer drill rated for SDS-PLUS bits and match drill diameter to anchor/manual specifications. Wear appropriate personal protective equipment including eye and hearing protection and a dust mask when drilling into concrete or masonry. When drilling through reinforced sections, proceed with controlled pressure and retract frequently to remove debris.
