Drill Bit for Concrete MODECO MN-61-077, cylindrical 12 mm, set of 10

MODECO cylindrical concrete drill bit set MN-61-077 contains ten 12 mm diameter bits designed for drilling holes in concrete and masonry. These bits are intended for use with compatible rotary or hammer drills and provide multiple replacements for construction, renovation and installation tasks. The set is suited for making holes for anchors, dowels and fasteners in solid concrete, block and other mineral substrates.

Advantages

The 12 mm cylindrical shank ensures stable mounting in standard drill chucks while the carbide tip geometry improves drilling efficiency and life when working in abrasive mineral materials. Supplied as a set of ten, the package reduces downtime by providing spare bits for repeated tasks and fast replacement on the job. The bits are manufactured for consistent diameter and straightness to produce clean, accurately sized holes for anchors and fixings.

Suitable for

• Drilling anchor and dowel holes in concrete walls and floors
• Installing fasteners for HVAC, electrical and plumbing fixtures
• Preparing mounting points for shelving, cabinets and railings
• General construction and renovation tasks on masonry and stone

Key specifications

• Drill bit diameter: 12 mm
• Shank type: cylindrical (round) shank for keyless or keyed chucks
• Quantity in set: 10 pieces
• Intended material: concrete and masonry (mineral substrates)
• Typical application: rotary and hammer drills

How to use

Select a compatible rotary or hammer drill and secure the 12 mm cylindrical shank in the drill chuck. Mark the drilling position, set the drill to the appropriate hammer or rotary mode depending on the substrate and apply steady pressure while drilling. Withdraw the bit occasionally to clear dust from the hole and maintain cutting efficiency. Replace bits from the set as wear or chipping reduces performance to maintain hole quality and drilling speed.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and dust mask when drilling concrete. Where possible, use a drill with depth stop to ensure consistent hole depth for anchors. For best results in hard concrete, start with a pilot hole and use appropriate hammer-drill settings; replace bits when carbide tips show visible wear or when hole quality degrades.
