Drilling and hole cutting for modern tiling jobs
Drilling through tile is not an afterthought. It is a finishing detail that sits at eye level in most bathrooms and kitchens, and it is often the first thing a client sees when looking at shower valves, heated towel rails and pipe entries. In 2026, large format porcelain and harder glazes have made accuracy and edge control more important. A cheap bit that wanders or overheats can fracture corners, chip a polished edge or force you into oversized trims.
HH Tiling Tools supports professional tilers across Chichester and West Sussex with drilling consumables that suit real site conditions. We can advise on wet versus dry drilling, drill speed, pressure, and how to start a clean hole on glazed surfaces. We also stock solutions for tidying edges with bevelling tools, so cutouts and penetrations look deliberate, not patched.
Diamond hole cutters
Ideal for common bathroom and kitchen holes: pipe passes, shower valve bodies, taps and fixings. The right diamond bond helps reduce chipping on porcelain and keeps the hole round, which matters when trims need to sit flush.
- Porcelain and ceramic compatibility
- Wet or dry drilling options depending on site needs
- Guides and starting tips for glazed surfaces
Core drills for repeated work
For teams doing multiple penetrations on large projects, core drills and robust cutters can offer steadier performance and better longevity. We can recommend approaches that maintain accuracy while reducing heat and premature wear.
- Suitable for dense porcelain and stone (with correct method)
- Consistency for repeated hole sizes and production work
- Guidance on speed, pressure and cooling
Bevelling and edge finishing
A quick bevel can transform how a cutout looks, especially around exposed penetrations or when trims are minimal. Bevelling solutions can also help reduce sharp edges that catch grout floats and sponges during finishing.
- Neater entries for pipework and valve plates
- Helps reduce visible chips on polished porcelain edges
- Useful on large format tile tools workflows
Guides, jigs and site technique
Most drilling failures are technique-related: too much pressure, wrong speed, poor starting control, or not enough cooling. The right guide and a simple routine can make holes more consistent and extend bit life.
- Starting accuracy on glossy glazes
- Cooling approaches for porcelain drilling
- Repeatability for multiple holes on one run
Practical sizing guide for trade holes
Every site is different, but these are common hole sizes that professional tilers request for bathroom and kitchen work. If you are unsure, share the fitting spec and we will help you choose a cutter size with sensible clearance.
| Application | Typical hole size range | Notes for clean results |
|---|---|---|
| Copper or plastic pipe passes | 20 mm to 35 mm | Allow for sleeves and movement. Keep the cutter cool for porcelain to reduce micro-chipping. |
| Shower valve body | 40 mm to 65 mm | Measure the plate and body spec. Start slowly to avoid skating on polished finishes. |
| Taps and waste outlets (basin areas) | 30 mm to 55 mm | Support the tile and avoid sudden pressure changes near edges and corners. |
| Fixings for rails and accessories | 6 mm to 12 mm | Pilot approach and steady speed. Consider a guide to keep the bit centred on glossy glazes. |
| Large penetrations and service access | 70 mm and up | Use a robust cutter and keep cooling consistent. Plan layout to avoid weak corners on large format tiles. |
If you are ordering professional tiling tools UK-wide, drilling consumables are one of the easiest ways to reduce rework. Clean penetrations help make silicone lines tighter, trims sit flatter and finishing faster, especially on large format porcelain.
