Drill accessory Drel CON-AOD-2316 diamond-brazed core bit 16 mm M14 shank

Diamond-brazed core bit by Drel CON-AOD-2316 delivers a 16 mm cutting diameter with an M14 threaded shank for use with M14-compatible rotary tools and angle grinders. Engineered for drilling precise holes in hard and brittle materials, this core bit uses a diamond-brazed cutting edge to increase wear resistance and prolong service life compared with conventional bits. Its compact 16 mm size is suitable for accurate hole-making where small diameters are required.

Advantages

The diamond-brazed cutting edge provides improved cutting performance and longer life when working on hard materials such as ceramic, porcelain, glass and some masonry. The M14 threaded shank ensures secure attachment to compatible rotary tools and angle grinders, reducing wobble and improving accuracy. The 16 mm diameter supports precise drilling in confined or detailed applications while the solid construction resists chipping and premature wear.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Creating openings in glass and glazed surfaces
• Small-diameter holes in brick, concrete and masonry for anchors or conduits
• Extracting small samples from hard materials for inspection or testing

Key specifications

• Cutting diameter: 16 mm
• Shank type: M14 threaded shank for secure tool attachment
• Cutting edge: diamond-brazed rim for enhanced wear resistance
• Recommended materials: ceramics, porcelain, glass, masonry

How to use

Select a compatible rotary tool or angle grinder with an M14 arbor and secure the core bit tightly. Mark the drilling position and start at low speed to establish a pilot contact point, applying light, steady pressure. Use intermittent drilling and allow the diamond-brazed edge to cut without excessive force; this reduces heat buildup and prolongs bit life. For brittle materials such as tile or glass, consider backing the workpiece or using support to avoid cracking. Cool the cutting area periodically if recommended by the tool manufacturer.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and gloves. Operate at moderate speed and avoid heavy pressure to maintain bit integrity and material quality. For prolonged cutting or dense masonry, use water cooling where tool and safety conditions permit to extend tool life and minimize dust.
