SDS-PLUS drill bit Makita NEMESISII 16 x 215 mm E-14744 for concrete and masonry

SDS-PLUS drill bit Makita NEMESISII 16 x 215 mm E-14744 for concrete and masonry is engineered for efficient drilling in reinforced concrete, brick and block. With a 16 mm working diameter and 215 mm overall length, this SDS-PLUS shank bit fits standard rotary hammers and is optimized for stable penetration, reliable centring and effective removal of dust and chips during operation. The carbide tip and flute geometry are designed to maintain drilling speed and reduce wear in common construction conditions.

Advantages

The design ensures consistent drilling performance in concrete and masonry while fitting SDS-PLUS chucks for quick bit changes. The flute profile promotes improved chip evacuation, reducing the chance of clogging and improving drilling stability. The tip geometry provides accurate starts and maintains cutting efficiency over multiple holes. Materials and manufacturing tolerances aim to extend service life under typical professional use.

Suitable for

• Drilling medium-diameter holes in reinforced concrete for anchors and dowels
• Creating passage holes in brick and aerated block walls
• Installation and renovation tasks requiring reliable, repeatable hole quality

Key specifications

• Shank type: SDS-PLUS compatible
• Diameter: 16 mm
• Overall length: 215 mm
• Intended material: concrete, reinforced concrete, brick, masonry block
• Tip material: carbide cutting tip for impact drilling
• Flute design: optimized for dust and chip evacuation

How to use

Insert the SDS-PLUS shank fully into the rotary hammer chuck and ensure it is locked before starting. Select the hammer drilling mode on the tool and apply steady axial pressure without forcing the bit; allow the tool and tip to do the work. Retract the bit periodically to clear dust and chips from the hole when drilling deep or long holes. Use appropriate drill speed and hammer force according to the rotary hammer manufacturer's recommendations for a 16 mm masonry bit.

Usage recommendations

For best results, wear appropriate personal protective equipment including eye and hearing protection and a dust mask. Match the bit to a rotary hammer compatible with SDS-PLUS shanks and maintain a moderate feed rate to avoid overheating. Replace worn bits to preserve hole accuracy and to reduce stress on the tool and fasteners.
