SDS-PLUS drill bit Makita NEMESISII 14 x 165 mm E-14635

The SDS-PLUS drill bit Makita NEMESISII 14 x 165 mm (model E-14635) is engineered for rotary and hammer drilling in concrete, masonry and natural stone. Its SDS-PLUS shank ensures fast, secure insertion into compatible chucks and efficient transfer of impact energy for reliable drilling in hard materials. The 14 mm cutting diameter and 165 mm overall length deliver accurate hole sizing for anchor bolts, dowels and through-holes while maintaining good chip evacuation during drilling.

Advantages

The carbide tip and optimized flute geometry provide extended cutting life and steady drilling speeds in abrasive materials. The SDS-PLUS connection reduces wobble and improves energy transfer in hammer mode. Durable manufacturing and precise tip centring result in clean entry holes and reduced walking on start-up, making the bit suitable for repeated use under professional conditions.

Suitable for

• Drilling 14 mm anchor and fixing holes in concrete and masonry
• Installing dowels, sleeve anchors and through-bolts
• Preparation work for plumbing and electrical installations in solid walls
• Light to medium-duty demolition and renovation tasks requiring precise holes

Key specifications

• Shank type: SDS-PLUS compatible
• Cutting diameter: 14 mm
• Overall length: 165 mm
• Tip material: tungsten carbide tipped
• Intended materials: concrete, masonry, natural stone
• Flute design: spiral for chip removal

How to use

Insert the SDS-PLUS shank into the drill’s chuck until it locks. Select an appropriate hammer or rotary-hammer mode on the tool according to the substrate hardness. Start drilling with light pressure to establish the entry point, then apply steady forward force while allowing the tool to supply impact action; avoid excessive axial force that can overheat or blunt the tip. Withdraw the bit periodically to clear debris and improve cooling when making deep holes. Use appropriate personal protective equipment such as eye and ear protection and dust extraction or masking when drilling overhead or in enclosed spaces.

Usage recommendations

For best results in reinforced concrete, pre-locate rebar and use intermittent drilling to prevent tip damage. Replace the bit when cutting performance noticeably decreases to maintain hole accuracy and reduce wear on the drill. When installing anchors, confirm hole depth and clean the hole of dust before inserting fixings.
