TDX Diamond Holesaw 25mm – Precise Wet Drilling for Ceramic, Glass, Marble & Porcelain

Perfect for Tilers, Renovators, Installers & DIY Hard-Surface Drilling Projects

The TDX Diamond Holesaw 25mm is designed for users who need accurate circular openings through suitable hard surfaces. Featuring a 25mm cutting diameter and diamond grit cutting edge, this holesaw is suitable for ceramic, non-hardened glass, marble, and porcelain. Designed for wet use only, it provides a practical solution for bathroom renovations, kitchen installations, tiling, repairs, and other projects requiring controlled hard-surface drilling.

Description – TDX Diamond Holesaw 25mm

The TDX Diamond Holesaw 25mm is a specialised drilling accessory designed for creating consistent 25mm circular openings in suitable ceramic, glass, marble, and porcelain materials.

Its diamond grit cutting edge provides the abrasive performance required for hard surfaces where conventional general-purpose drill bits may not be appropriate.

With a fixed 25mm cutting diameter, the holesaw provides a clearly defined opening size for suitable fittings, fixtures, and installation components. This makes it useful for professional tradespeople and DIY users who need consistent circular holes during renovation and installation work.

Ceramic is one of the primary specified applications. Ceramic tiles are widely used throughout bathrooms, kitchens, laundries, and other areas where fittings may need to pass through or attach to tiled surfaces.

Using a dedicated diamond holesaw provides a practical method for creating a 25mm circular opening in suitable ceramic rather than attempting to use an accessory intended for wood or metal.

The holesaw is also suitable for porcelain. Porcelain can be particularly hard and demanding to drill, making a diamond grit cutting edge an appropriate option for suitable tile installations and renovation projects.

Marble is another specified material. When suitable marble surfaces require a 25mm opening, this TDX holesaw provides a dedicated diamond cutting accessory for the task.

Glass can also be drilled, excluding hardened glass. This limitation is important because hardened or toughened glass has different structural characteristics and should not be drilled using this product.

Users should therefore identify the glass type before beginning work. If the material is hardened or toughened, this holesaw should not be used.

A key operating requirement is wet use only. Water should be maintained at the cutting area throughout drilling according to appropriate operating procedures.

Wet drilling helps control heat generated between the diamond grit cutting edge and the hard material. This supports appropriate cutting conditions and helps prevent excessive heat build-up.

Water can also assist with managing material residue during the drilling process. The holesaw should not be operated dry.

For tilers, the 25mm diameter provides a useful option when preparing suitable ceramic or porcelain tiles for fixtures, fittings, and other installation components.

Renovators can keep the holesaw available for bathrooms, kitchens, laundries, and other property improvement projects involving hard tiled surfaces.

Installers may also find the 25mm size practical when suitable fittings require a moderate circular opening. The exact diameter required should always be checked before drilling.

When working with marble or suitable glass, controlled technique is particularly important. The workpiece should be appropriately supported to reduce movement and unnecessary stress.

Users should avoid excessive pressure and allow the diamond grit edge to work progressively through the material.

Accurate positioning should be established before cutting begins. This is particularly important on finished tile, marble, or glass surfaces where incorrectly positioned holes can be difficult to correct.

The TDX Diamond Holesaw 25mm can also form part of a broader collection containing different diamond holesaw diameters. This allows users to select the appropriate size according to each installation requirement.

For professional tilers and installers, maintaining several sizes can improve workflow across projects involving different fittings and components.

DIY users can also benefit from the clearly defined 25mm size and material compatibility when completing suitable home renovation projects.

The holesaw should be inspected before use. Damaged or excessively worn cutting accessories should not be operated.

Users should also confirm compatibility with their drilling equipment and follow the power tool manufacturer's operating requirements.

Appropriate personal protective equipment should be used according to the tool manufacturer's instructions and working environment.

For New Zealand tilers, builders, renovators, installers, craftspeople, and DIY users, the TDX Diamond Holesaw 25mm provides a practical combination of accurate sizing, diamond grit cutting performance, and compatibility with several commonly encountered hard surfaces.
