Diamond drill bit Yato YT-60422 6 mm 1 pc(s)

The Yato YT-60422 6 mm diamond drill bit is designed for precise drilling in hard and abrasive materials. Supplied as a single unit, this drill bit has a 6 mm cutting diameter and a diamond-coated tip that improves cutting efficiency and extends tool life when used with appropriate drilling techniques and equipment. The design targets accuracy and consistent hole quality in demanding tasks that require a small-diameter, hard-material-capable bit.

Advantages

The diamond-coated tip provides superior wear resistance compared with standard HSS or carbide bits when working on glass, ceramic, porcelain, or other brittle hard surfaces. The 6 mm diameter ensures stable, narrowly toleranced holes suitable for mounting and finishing tasks. Its single-piece supply makes it convenient to add to a toolset without extra packaging, and the compact size reduces vibration during controlled drilling, improving hole roundness and surface finish.

Suitable for

• Drilling holes in glass and mirrors
• Drilling ceramic tiles and porcelain
• Creating holes in stone, marble, and similar natural stone materials
• Precision work for mounting fixtures, hardware, or decorative inserts

Key specifications

• Cutting diameter: 6 mm
• Tip type: diamond-coated for abrasive materials
• Quantity: 1 piece
• Intended use: wet or low-speed dry drilling depending on material and equipment
• Compatibility: standard rotary drills with appropriate collet or chuck for the shank

How to use

Select a drill or drill press that allows controlled rotational speed and steady pressure. For brittle materials such as glass, ceramic, or porcelain, begin at low speed and apply light, steady pressure. Use water cooling or periodic lubrication to reduce heat and prolong tip life when the material and working environment permit wet drilling. Secure the workpiece to prevent movement and use a guide or template if precise hole placement is required. If using a handheld drill, keep the tool steady and perpendicular to the surface to avoid chipping. After drilling, clean the hole and inspect for any cracks or irregularities.

Usage recommendations

For best results, use low to moderate rotational speeds, consistent light pressure, and continuous or intermittent water cooling when drilling hard, brittle materials. Wear appropriate eye protection and take steps to clamp the workpiece to prevent slipping or vibration that can cause chipping.
