Product information

Description

GRAPHITE 4 mm concrete drill bit with a cylindrical shank is designed for drilling small-diameter holes in concrete, masonry and similar hard materials. The bit combines a hardened cutting tip with a durable steel body to withstand rotary hammer or standard drill use. Its 4 mm diameter and compact length make it suitable for precision work such as fixing anchors, dowels and creating passages for electrical or plumbing lines during light installation tasks.

Advantages

The hardened tip provides effective cutting and longer edge life when penetrating concrete and masonry. The steel body ensures torsional strength and resistance to bending under normal drilling conditions. The cylindrical shank fits standard chucks, allowing quick mounting in most rotary drills and hammer drills. The small diameter enables accurate positioning and minimizes surface damage around the drilled hole.

Suitable for

Drilling small holes in concrete and cement-based masonry
Installing wall anchors and plastic dowels
Creating passages for electrical conduits and small plumbing lines
Light repair and installation work on construction sites or at home

Key specifications

Diameter: 4 mm
Intended material: concrete, masonry and similar hard substrates
Shank type: cylindrical (suitable for standard drill chucks)
Tip: hardened cutting tip for improved wear resistance
Body material: high-strength steel for torsional stability

How to use

Mark the drilling point and secure the work surface if necessary. Use an appropriate drill or rotary hammer set to hammer-drill mode for reinforced concrete or rotary mode for softer masonry. Clamp the cylindrical shank in the drill chuck ensuring it is centered and tightened. Start drilling at low speed to create a guide spot, then increase speed and apply steady, moderate pressure. Withdraw the bit periodically to clear dust and prevent overheating. After drilling, clean the hole of debris before inserting anchors or dowels.

Usage recommendations

Use suitable personal protective equipment including safety glasses and hearing protection. For reinforced concrete or prolonged drilling, consider using a drill with hammer function and select a bit with appropriate length and diameter. Avoid excessive lateral force to prevent breakage of the small-diameter bit and replace the bit if the cutting tip shows significant wear.
