Drill Bit GRAPHITE SDS+ 14 mm for Concrete, model 57H462

GRAPHITE SDS+ 14 mm drill bit model 57H462 is a rotary and hammer drill accessory designed for creating 14 mm diameter holes in concrete, masonry and reinforced concrete. The bit is manufactured to work with SDS+ chucks and is intended for tasks that require precise, clean holes for anchors, dowels or through-fixings. Its geometry and carbide tip are optimized for drilling into hard mineral materials while maintaining hole accuracy and acceptable service life.

Advantages

The drill bit provides compatibility with SDS+ rotary and hammer drills, ensuring secure retention and efficient power transfer. The carbide tip and flute design reduce wear and help evacuate dust and debris from the hole during drilling. With a 14 mm diameter, the bit matches common anchor and dowel sizes used in installation and construction work. Its construction offers a balance between material hardness and shock resistance for standard professional and DIY applications.

Suitable for

• Drilling 14 mm holes in concrete and reinforced concrete
• Creating anchor or dowel holes for installation of fixtures and fittings
• Masonry work where a 14 mm through-hole is required
• Repair and renovation tasks involving anchor fixing

Key specifications

• Diameter: 14 mm
• Shank type: SDS+
• Intended material: concrete, reinforced concrete, masonry
• Tip material: carbide cutting tip for improved wear resistance
• Application: rotary and hammer drilling modes

How to use

Secure the drill bit in the SDS+ chuck according to the drill manufacturer's instructions. Select an appropriate drilling mode (hammer or rotary with hammer) and set the drill to a suitable speed for a 14 mm bit in concrete. Mark the drilling point, start drilling at low speed to seat the tip, then apply steady axial pressure while allowing the hammer action to break the material. Periodically withdraw the bit to clear dust from the hole for improved cutting efficiency and cooler operation. Use appropriate personal protective equipment, including safety glasses, hearing protection and a dust mask.

Usage recommendations

For best results when installing anchors or dowels, drill to the correct depth, clean the hole of dust and debris before inserting fasteners, and follow anchor manufacturer instructions for hole diameter and embedment depth.
