Concrete SDS-plus drill bit Smart 5.5 x 360/300 mm

Smart Concrete SDS-plus drill bit 5.5 x 360/300 mm is designed for drilling into concrete, masonry and natural stone using rotary and rotary‑hammer drills with an SDS-plus shank. The bit’s 5.5 mm diameter and 300 mm working length allow for accurate through and blind holes in construction, installation and repair tasks where a durable masonry drill is required.

Advantages

The drill bit combines an SDS-plus shank for fast, secure tool mounting with a geometry optimized for efficient debris removal and reduced clogging. Its hardened carbide tip improves wear resistance and maintains cutting performance in abrasive materials. The long overall length enables deep drilling while the specified working length ensures stable guidance and straight holes.

Suitable for

• Drilling holes for anchors and fasteners in concrete and blockwork
• Installation of electrical conduits and plumbing through masonry
• Repair and retrofit work requiring blind or through holes
• Professional and DIY tasks with SDS-plus rotary or rotary‑hammer drills

Key specifications

• Diameter: 5.5 mm
• Overall length: 360 mm
• Working length (useful length): 300 mm
• Shank type: SDS-plus compatible
• Tip material: carbide cutting tip for masonry
• Intended materials: concrete, masonry, natural stone

How to use

Fit the SDS-plus shank securely into the drill chuck according to the drill manufacturer’s instructions. Select the rotary or rotary‑hammer mode depending on the material and task. Start drilling at low speed to establish position, then apply steady pressure and increase speed as appropriate. Withdraw the bit periodically to clear dust from the hole and prevent overheating. For through-holes, continue until the required depth is reached; for blind holes, monitor depth carefully to avoid exceeding the working length.

Usage recommendations

Use personal protective equipment including safety glasses and dust mask when drilling. For best results in reinforced concrete, use short drilling intervals and remove dust frequently. Match drill speed and hammer action to the material: lower speed with hammering for toughness, higher speed without hammering for softer masonry.
