Drill Bit GRAPHITE 5 mm SDS+ for concrete, model 57H404

GRAPHITE 5 mm SDS+ drill bit model 57H404 is designed for drilling precise holes in concrete and masonry. This SDS+ rotary drill bit fits SDS+ chucks and is intended for use with hammer drills and rotary hammers. Its 5 mm diameter makes it suitable for creating anchor and dowel holes, as well as for installation and light repair tasks where accurate, straight drilling is required.

Advantages

The drill bit offers stable engagement with SDS+ chucks for reduced slippage during hammering action and consistent transfer of percussion energy. Its small 5 mm diameter enables accurate hole placement and minimal material removal, helping to prevent cracking in surrounding masonry. The bit geometry and flute design allow effective dust extraction from the hole, improving drilling speed and reducing bit wear under light to medium-duty use.

Suitable for

• Drilling anchor and dowel holes in concrete and brick
• Installation of fixtures, fittings and conduits in masonry
• Light to medium-duty renovation and repair tasks

Key specifications

• Shank type: SDS+ compatible
• Drill diameter: 5 mm
• Intended material: concrete and masonry
• Tool compatibility: hammer drills and rotary hammers with SDS+ chuck
• Application range: light to medium-duty drilling tasks

How to use

Secure the drill bit in the SDS+ chuck according to the drill manufacturer's instructions until it locks in place. Select the hammer or rotary mode when drilling into concrete or masonry. Start at low speed to position the bit, then increase speed and apply steady axial pressure while allowing the hammer action to do most of the work. Withdraw the bit periodically to clear dust from the hole and to avoid overheating. For through-holes or deeper holes, drill in stages if necessary to maintain accuracy and prevent bit binding.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. Match the 5 mm diameter to the recommended anchor or dowel size, and avoid applying excessive lateral force to preserve bit life. For best results in reinforced concrete, check for rebar before drilling and use a dedicated rebar-cutting bit if required.
