Diamond Hole Saw Milwaukee OTWORNICA ROCKET 20 x 45-3 x M14

Diamond hole saw Milwaukee OTWORNICA ROCKET 20 x 45-3 x M14 is a diamond-segmented cutting tool designed for drilling precise circular openings with a 20 mm diameter and 45 mm cutting depth. The M14 threaded connection allows direct attachment to compatible angle grinders and certain rotary tools, enabling fast removal of material and clean-edged holes in hard substrates. This tool is intended for applications where a durable diamond edge and controlled cutting depth are required.

Advantages

The diamond-segmented rim provides high wear resistance and consistent cutting performance when working with abrasive and hard materials. The 45 mm cutting depth permits through and partial-depth holes in thicker substrates while maintaining axial stability. The M14 thread ensures secure mounting to a range of handheld power tools, reducing runout and vibration during cutting. The compact 20 mm diameter allows precise openings for pipes, conduits, and service penetrations.

Suitable for

• Drilling holes for plumbing penetrations through tiles, stone and masonry
• Creating openings for electrical conduits and cable glands in hard surfaces
• Cutting service holes in construction materials such as concrete, brick and ceramic

Key specifications

• Cutting diameter: 20 mm
• Cutting depth: 45 mm
• Cutting edge: diamond-segmented rim for abrasive materials
• Connection type: M14 threaded mount for direct tool attachment
• Typical use: dry or wet cutting depending on tool and material; designed for hard substrates

How to use

Fit the hole saw securely to a compatible power tool with an M14 arbor or direct spindle, following the power tool manufacturer's instructions. Mark the drilling location, ensure the workpiece is supported and stable, and start the tool at a low speed to establish the cut. Apply steady, moderate pressure and let the diamond segments cut without forcing the tool; increase speed as appropriate for the material and tool. For sustained life and cleaner holes, use cooling or periodic pecking and clearing of debris when working in dense materials. After cutting, stop the tool and allow the hole saw to cool before removing it.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and dust control. Where applicable, employ water or a coolant to reduce heat and prolong cutting life; verify that the chosen technique is compatible with the power tool. Inspect the diamond rim before use and replace the hole saw if segments are damaged or excessively worn.
