Drill bit Verto 4 mm for concrete, cylindrical shank, model 60H172

The Verto 4 mm concrete drill bit (model 60H172) is a carbide-tipped masonry bit with a cylindrical shank designed for drilling precise 4 mm holes in concrete and other masonry materials. Intended for use with rotary and hammer drills that accept a cylindrical shank, this drill bit is sized for small-diameter anchor bolts, dowels and fixings commonly used in construction and installation work. The compact diameter and hardened tip enable accurate positioning and controlled drilling in dense substrates.

Advantages

The Verto 4 mm bit delivers a precise 4 mm bore with minimal wobble thanks to its straight cylindrical shank. Its masonry-oriented tip and hardened cutting edges are designed to withstand impact drilling in concrete and brick. The slim profile reduces material removal for fast penetration when making holes for small anchors or screws. Compatibility with standard cylindrical-shank drill chucks makes it suitable for a wide range of rotary and hammer drills.

Suitable for

• Drilling 4 mm holes for anchor bolts, dowels and small fixings in concrete and masonry
• Light construction, installation and repair tasks on brick, block and concrete
• Pre-drilling for fasteners in renovation and finishing work

Key specifications

• Diameter: 4 mm
• Shank type: cylindrical shank for standard drill chucks
• Intended material: concrete and masonry
• Typical applications: small-diameter anchoring and fixing holes

How to use

Fit the Verto 4 mm concrete drill bit into a compatible drill chuck and tighten securely. Where possible, use a hammer drill mode for efficient penetration in concrete; for rotary-only drills, apply steady moderate pressure and keep the drill perpendicular to the surface. Start with a low speed to establish the hole, then increase speed as the bit progresses. Periodically withdraw the bit to clear dust from the hole and prevent overheating. For accurate anchor placement, mark the drilling point and use a depth stop or tape on the bit if a controlled hole depth is required.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, gloves and hearing protection. Match drill mode and speed to the substrate: use hammer action for hard concrete and rotary mode for lighter masonry when applicable. Replace the bit if cutting performance decreases or if the tip becomes chipped to maintain clean, accurate holes.
