Drill bit Drel KORONA M14 with sintered diamond coating, 14 mm, CON-AOD-2314

Drel KORONA M14 drill bit CON-AOD-2314 is a 14 mm cutting tool with a sintered diamond coating and an M14 shank, designed for use with angle grinders or compatible M14 holders. The diamond abrasive surface enhances wear resistance and cutting precision when working with hard and abrasive materials. This drill bit is engineered for controlled material removal in masonry, ceramics, tiles and similar surfaces where conventional bits wear quickly.

Advantages

The sintered diamond coating provides improved durability and longer life compared with uncoated bits, maintaining cutting performance on abrasive substrates. The 14 mm diameter and rigid construction enable stable drilling and consistent hole size. The M14 shank ensures secure attachment to angle grinders and M14-compatible holders, reducing slippage during operation. The bit is suitable for repeated use on hard materials without rapid loss of cutting edge.

Suitable for

• Masonry drilling (concrete, brick, block)
• Ceramic and porcelain tiles
• Abrasive stone and engineered stone
• Repair and renovation tasks requiring precise holes

Key specifications

• Diameter: 14 mm
• Coating: sintered diamond (diamond abrasive)
• Shank type: threaded M14 compatible
• Intended use: rotary drilling with angle grinders or M14 holders
• Material compatibility: masonry, ceramics, tiles, abrasive stone

How to use

Fit the drill bit into a compatible angle grinder or an appropriate M14 holder according to the tool manufacturer's instructions. Secure the shank firmly before starting. Begin drilling at low speed to establish the hole location, then apply steady pressure and maintain a perpendicular angle to the work surface. For tiled or ceramic surfaces, start from a shallow pilot recess or use masking to reduce slipping. Use intermittent drilling with light pressure on very hard or thick materials to avoid overheating; allow the bit to cool between passes if necessary.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, dust mask and hearing protection. For improved bit life and cleaner holes, use water or a suitable coolant where compatible with the workpiece and tool, and avoid excessive side load or twisting forces during drilling.
