Concrete drill bit MODECO MN61076 cylindrical 12 mm, 10 pcs

MODECO MN61076 cylindrical concrete drill bit set with 12 mm diameter, supplied as a pack of 10 pieces, is designed for drilling into concrete, masonry and similar hard materials. The bits have cylindrical shanks compatible with hammer drills and rotary hammers that accept straight shanks. This set is intended for construction, renovation and installation tasks where reliable, repeatable masonry holes are required.

Advantages

The drill bits feature a durable carbide tip geometry optimized for penetration in concrete and brick while maintaining tip sharpness over repeated use. The cylindrical shank ensures simple, stable clamping in standard chucks and allows use with a broad range of hammer drill and rotary hammer models. Supplied in a 10-piece pack, the set reduces downtime by providing spares for multiple holes or for swapping worn bits quickly.

Suitable for

• Drilling holes in concrete and reinforced concrete (non-specialized structural drilling)
• Creating anchor, dowel and screw holes in masonry and brick
• General renovation and installation tasks: mounting fixtures, conduit and cable entry
• Work with hammer drills and rotary hammers that accept cylindrical shanks

Key specifications

• Drill bit diameter: 12 mm
• Shank type: cylindrical (straight) shank compatible with standard chucks
• Material tip: carbide cutting tip for masonry
• Quantity in set: 10 pieces
• Intended materials: concrete, masonry, brick and similar hard substrates

How to use

Select an appropriate drill speed and hammer function according to the base material. Secure the bit in the drill chuck so the cylindrical shank is clamped firmly. When drilling, apply steady axial pressure without forcing the bit; allow the hammer action and the carbide tip to cut through the material. Periodically withdraw the bit to clear dust and debris and reduce heat build-up. Replace bits from the pack as they show significant wear or chipping.

Usage recommendations

Use appropriate personal protective equipment — safety glasses, hearing protection and dust mask — and secure workpieces. For reinforced concrete, use progressive drilling technique and avoid excessive pressure; if encountering rebar, stop and switch to a rebar cutting method. Store the bits dry and in their original packaging to protect the carbide tips.
