YATO YT-60442 is a single-piece diamond-coated drill bit supplied as one unit. Designed for precise dry cutting and hole-making in hard brittle materials, this YATO-branded bit fits grinders with an M14 thread and is intended for tasks that require accurate, clean edges when working with stoneware, ceramics, porcelain and composite surfaces.
Advantages
The diamond-coated cutting edge, applied by vacuum brazing to a steel body, provides increased resistance to high temperatures, friction and mechanical wear. The single-piece construction reduces the risk of vibration-related breakage and supports stable rotation up to the specified maximum speed. Supplied as a single unit, the bit is suitable for replacement or for single drilling tasks where one dedicated tool is needed.
Suitable for
- Dry cutting and drilling of stoneware tiles
- Cutting holes in ceramic and porcelain surfaces
- Creating openings for plumbing fixtures and drains
- Detail work on composite cladding and decorative elements
Key specifications
- Cutting edge: diamond-coated
- Body material: steel
- Attachment/thread: M14 (for grinders)
- Intended use: dry cutting and drilling of stoneware, ceramics, porcelain and composites
- Maximum rotational speed: 12,200 rpm
How to use
Fit the YATO YT-60442 drill bit into a compatible grinder with an M14 thread and secure it according to the tool manufacturer’s instructions. Position the bit at the mark on the workpiece, start the grinder at a moderate speed, and gradually increase up to the maximum rated speed if required by the material and tool stability. Apply steady, light pressure to avoid overheating or chipping and stop periodically if the bit or workpiece becomes hot. Because the bit is designed for dry cutting, do not use continuous water cooling unless the grinder and bit specifications explicitly allow it.
Usage recommendations
Use appropriate personal protective equipment, including eye protection, gloves and a dust mask. Ensure the grinder is suitable for the stated maximum speed and that the workpiece is securely clamped. For best results on brittle tiles, start with a low speed to create a pilot groove, then increase speed as needed while maintaining light pressure. Replace the bit when the cutting performance noticeably decreases to avoid damage to the workpiece.
