BRSCHNITT Diamond Core Drill Bit Set, 6 mm

What matters most

The set pairs diamond core drill bits in six listed sizes with a separate chamfer bit, giving you tools for both making holes and finishing an edge. That combination is aimed at hard surfaces such as porcelain and ceramic tile, marble and granite, rather than general-purpose drilling.

The core bits are 6, 8, 10, 20, 25 and 35 mm, with a 10 mm diamond height and 65 mm total length. The 2-inch chamfer bit has a 46 mm workable length, #80 grit and a 60-degree top angle. Those details help you judge whether the sizes and working lengths suit the job, the listing does not specify a dust-control system or a drilling guide.

For example, if you need a hole through a bathroom tile for a fitting, choose the core bit that matches the required opening, then use the chamfer bit where an angled edge is needed. Keep in mind that an angle grinder requires an angle-grinder drill chuck for installation. The product details do not say whether that chuck is included.

How to use it

The listing describes the core bits for dry drilling, with water as a way to prolong their service life. That gives you a choice of approach: dry drilling may suit a small, straightforward task, while adding water may be worth considering when extending bit life matters. No specific water-feed method is provided, so the setup will depend on your work area and equipment.

The bits are listed for electric drills, hand drills and bench drills. The triangular-shank core bits and hex-shank chamfer bit have different shank formats, so check that the tool you plan to use can accept each one. The listed materials also extend beyond tile to masonry, concrete, glass and hard plastic, the description does not provide material-specific settings or performance figures.

Practical tips

Before drilling, match the core bit to the hole size you need and make sure the workpiece is supported. A bench drill may suit a job where you want a stable setup, while a hand drill offers a more portable approach. The listing gives no recommended speed, so avoid assuming one setting will suit every surface or bit.

Water is noted as a way to prolong bit life, but the kit details do not explain how to apply it. If you are working on a finished tile, plan where the opening should sit before starting, a mismatch between the required hole and the supplied sizes could mean this set is not the right fit. The separate chamfer bit is for edge finishing, not a substitute for selecting the correct core bit.

Buying questions

What sizes are included? The core drill bits are listed as 6, 8, 10, 20, 25 and 35 mm. A 2-inch chamfer bit is also included.

Can it be used on porcelain tile? Porcelain tile is specifically named, alongside ceramic tile, marble and granite. Masonry, concrete, glass and hard plastic are listed too, but no material-specific results are given.

Does it work with an angle grinder? The listing says an angle-grinder drill chuck is required for installation. It also names electric, hand and bench drills as suitable tools.

In your case

Puede interesarte si you need one of the listed hole sizes for tile or another named hard material, and the separate chamfer bit is useful for the edge finish you have in mind. No te encajará si your job needs a different opening size, a specified drilling speed or detailed guidance for controlling water and debris. Compared with buying a single-purpose core bit, this kit brings several sizes and a chamfer bit together, a single bit may be the simpler choice when you know you only need one size.
