Drill bit Drel CON-AOD-2312 — diamond-packed brazed core bit, 12 mm, M14 shank

Drel CON-AOD-2312 is a 12 mm diamond-packed brazed core bit with an M14 threaded shank designed for rotary drills. It is intended for cutting and drilling hard mineral materials where diamond grit on the cutting edge increases wear resistance and maintains drilling precision. The core bit is adapted for use in construction and renovation tasks that require reliable hole-making in concrete, stone and ceramic surfaces.

Advantages

The diamond-packed brazed cutting edge provides extended service life and consistent cutting performance on abrasive materials. The M14 threaded shank ensures secure attachment to a wide range of rotary drills and angle grinders without additional adapters. The 12 mm diameter offers a balance between small-hole precision and sufficient bore for anchor and conduit installation. The brazed design reduces the risk of segment loss and supports effective heat dissipation during intermittent drilling.

Suitable for

• Drilling small-diameter holes in concrete and reinforced concrete
• Creating holes in natural stone and engineered stone
• Piercing ceramic tiles and porcelain in installation works
• Preparing passages for screws, anchors and small conduits in renovation projects

Key specifications

• Cutting technology: diamond-packed brazed edge for abrasive materials
• Drill core diameter: 12 mm
• Shank type: M14 threaded shank for direct mounting
• Typical compatible tools: rotary drills and angle grinders with M14 interface
• Intended materials: concrete, stone, ceramics and similar masonry

How to use

Secure the core bit to the drill or angle grinder with an M14 interface according to the tool manufacturer's instructions. Mark the drilling location and start at low speed to establish the cutting position, then increase speed and apply steady, moderate pressure. Use short drilling intervals to avoid overheating; withdraw occasionally to clear dust and cool the cutting edge. For reinforced concrete, proceed carefully when encountering rebar; reduce feed force and keep the bit aligned to prevent wobble.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, dust mask and hearing protection. For prolonged drilling or hard materials, employ water cooling or periodic pauses to extend tool life. Match drill speed and feed pressure to the material hardness: lower speeds and lighter pressure for ceramics, moderate speeds for concrete and stone.
