Drill bit Makita NEMESISII SDS-PLUS 16 x 315 mm

The Makita NEMESISII SDS-PLUS 16 x 315 mm drill bit is a straight-shank SDS-PLUS accessory designed for rotary hammers with SDS-PLUS chucks. It is intended to drill 16 mm diameter holes to a working length of 315 mm in masonry, concrete and natural stone. The geometry and flute design support efficient chipping and dust evacuation during deep drilling operations, making it suitable for both professional tradespeople and DIY users requiring precise, deeper holes for anchors, sleeves and through-conduit passages.

Advantages

The NEMESISII bit offers optimized tip and flute geometry to reduce wandering and improve centring at the start of a hole. Its SDS-PLUS shank ensures secure, rapid tool changes and reliable torque transfer with compatible rotary hammers. The long working length of 315 mm provides access to deeper drilling positions without the need for extensions, and the bit is balanced for stable rotation to minimise vibration in handheld drilling tasks.

Suitable for

• Drilling 16 mm anchor and fastening holes in concrete and masonry
• Creating passages for cables and conduits through walls and floors
• Professional installation tasks in construction and renovation
• DIY projects requiring deep, accurately positioned holes

Key specifications

• Shank type: SDS-PLUS
• Diameter: 16 mm
• Working length: 315 mm
• Material compatibility: masonry, concrete, natural stone
• Tip and flute design: optimized for efficient dust removal and centring

How to use

Fit the SDS-PLUS shank into a compatible rotary hammer and ensure the chuck locks securely before starting. Mark the drilling point and, where possible, use the hammer drill in percussion mode for masonry and concrete. Maintain steady pressure and allow the tool to do the work; avoid excessive side load that can damage the bit. Periodically remove the bit from the hole to clear dust and allow cooling during extended drilling sessions. For through-holes, confirm depth before completing the hole to avoid overdrilling.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling concrete or masonry. Match the drill speed and percussion settings to the rotary hammer manufacturer’s guidance for 16 mm SDS-PLUS bits and replace the bit if tip wear or flute damage reduces drilling performance.
