Drill Bit MODECO MN-61-065 — Concrete Cylindrical 8 mm, 10 pcs

Concrete cylindrical drill bits MODECO MN-61-065, 8 mm diameter, pack of 10 pieces, are designed for drilling into concrete and similar masonry materials. These cylindrical shank bits have a hard cutting tip and a geometry optimized for penetration into dense substrates. Supplied in a practical set of ten, they are intended for repeated use in construction, installation of anchors, electrical and plumbing work where an 8 mm hole is required. They are compatible with hammer and rotary-percussion drills that accept cylindrical shanks of this diameter.

Advantages

The MODECO 8 mm concrete cylindrical bits offer consistent hole diameter and good wear resistance for routine on-site tasks. Their cylindrical shank ensures stable clamping in standard chucks, and the tip design reduces walking at the start of drilling. The set of ten allows multiple anchor or fixture installations without frequent tool changes, and the bits are suitable for use with both hammer action and regular rotary drilling where masonry drilling is needed.

Suitable for

• Drilling holes in concrete for anchors and plugs
• Preparing openings for electrical wiring and conduit installation
• Creating fixing points for plumbing brackets and supports
• General masonry drilling on block, brick and reinforced concrete surfaces

Key specifications

• Diameter: 8 mm
• Pack quantity: 10 pieces
• Shank type: cylindrical
• Intended material: concrete and similar masonry
• Compatible drill types: hammer drills and rotary-percussion drills with suitable chucks

How to use

Select an appropriate drill with a chuck that securely holds cylindrical shanks. Mark the drilling point and, if necessary, use a center punch or pilot mark to reduce bit walking. Fit the MODECO 8 mm bit into the drill chuck and tighten firmly. For reinforced concrete or hard substrates use the hammer function; for lighter masonry or when precision is required use rotary mode. Apply steady axial pressure and withdraw periodically to clear dust and prevent bit overheating. After drilling, clean the hole of debris before inserting anchors or fasteners.

Usage recommendations

Use suitable personal protective equipment (safety glasses, dust mask and hearing protection) and secure the workpiece. For increased bit life, avoid excessive side pressure and allow the bit to cool between prolonged drilling cycles. Inspect bits for wear or damage before use and replace when cutting edges become blunt.
