Drill bit Makita NEMESISII E-14554 SDS-PLUS 12 mm x 265 mm

The Makita NEMESISII SDS-PLUS 12 mm x 265 mm drill bit is designed for use with SDS-PLUS rotary hammers to drill accurate, deep holes in masonry and concrete. With a 12 mm cutting diameter and a 265 mm overall length, this bit is intended for applications that require extended reach while maintaining stable rotary hammer engagement and consistent drilling performance.

Advantages

The drill bit features a carbide tip and a flute geometry optimized for dust evacuation, providing efficient penetration and longer service life under frequent use. The SDS-PLUS shank design ensures secure retention in compatible rotary hammers and fast bit changes. Precision ground cutting edges deliver straight holes with minimal wandering.

Suitable for

• Drilling through concrete for anchor and through-holes
• Installing anchors, dowels, and rebar starter holes
• Deep drilling where extended reach is required
• Professional construction and renovation tasks
• DIY projects involving masonry and blockwork

Key specifications

• Shank type: SDS-PLUS compatible
• Cutting diameter: 12 mm
• Total length: 265 mm
• Material: carbide tip with high-strength steel body
• Flute design: spiral flute for efficient dust removal
• Intended materials: concrete, masonry, brick, block

How to use

Select a rotary hammer with an SDS-PLUS chuck and install the bit by inserting the shank until it locks. Use the rotary hammer in hammer-drilling mode for masonry and concrete. Apply steady, moderate pressure and allow the tool and bit to do the work; avoid excessive side load that can cause bit wandering or breakage. For deep holes, periodically withdraw the bit to clear accumulated dust and chips, improving drilling speed and reducing heat buildup.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection, and dust mask or vacuum dust extraction when drilling concrete. Match drill speed and hammer impact force to the rotary hammer and material hardness. Replace the bit when cutting performance declines or if the carbide tip is chipped to maintain hole accuracy and safety.
