Diamond core hole saw M14 44 mm MILWAUKEE KORONA Diamond Plus

The Diamond core hole saw M14 44 mm MILWAUKEE KORONA Diamond Plus is a rotary accessory engineered for cutting clean circular openings in hard, brittle materials. With an M14 threaded mount it fits angle grinders and rotary tools that accept M14 accessories and provides a 44 mm cutting diameter suited for creating precise holes in ceramic, porcelain and glazed tile during installation or repair work.

Advantages

This diamond core hole saw features a continuous diamond cutting edge designed to deliver smooth holes with reduced chipping on fragile surfaces. The M14 thread provides secure attachment to compatible grinders and the 44 mm diameter offers a common size for pipe, conduit or fitting penetrations. The Diamond Plus construction improves cut life and maintains consistent cutting performance across repetitive drilling tasks.

Suitable for

• Drilling circular holes in ceramic and porcelain tiles
• Making openings for pipes, conduits and fixtures in tiled surfaces
• Tile repair and retrofit work requiring precise, clean cuts
• Use with angle grinders and rotary tools fitted with M14-mount accessories

When it may not be suitable

This core hole saw is intended for hard, brittle materials such as ceramic, porcelain and glazed tile; it is not designed for heavy masonry like reinforced concrete or for cutting soft materials such as wood or plastics where alternative saw types would be more effective. Also, because it uses an M14 thread it requires a tool that accepts M14-mounted accessories—without that, an adapter or a different arbor will be necessary.

Key specifications

• Cutting diameter: 44 mm
• Mount type: M14 threaded mount
• Cutting technology: diamond-edged continuous rim (Diamond Plus)
• Intended material types: ceramic, porcelain, glazed tile and similar brittle surfaces
• Typical use: dry or wet rotary cutting depending on tool and application technique

How to use

Secure the hole saw to an angle grinder or rotary tool with an M14 mount according to the tool manufacturer’s instructions. Mark the hole position on the tile and start drilling at low speed to establish the initial groove; then increase speed and maintain steady, even pressure. For brittle tiles, intermittent drilling and light pressure help reduce chipping. Where applicable, use water cooling or periodic wetting of the cutting zone to extend diamond life and reduce dust, following the safety guidance of both the tool and accessory manufacturers.

What to consider before purchase

• Confirm your tool accepts M14-threaded accessories or obtain the correct adapter
• Verify 44 mm is the required hole size for your pipe, fixture, or fitting
• Check suitability for the exact tile type and thickness you will drill
• Prepare appropriate PPE and dust/wet management methods for the task

Usage recommendations

Use steady, controlled speeds and avoid excessive force; consider water cooling for longer life and reduced dust when drilling ceramic or porcelain tiles with the M14 44 mm MILWAUKEE KORONA Diamond Plus.
