## Long description

Rockforce core bits set for ceramic and porcelain contains seven precision-cut diamond-tipped hole saws designed for drilling clean circular openings in ceramic tiles and porcelain stoneware. The set includes core bits with diameters of 33, 53, 67, 73 and 83 mm, enabling professional and DIY users to make holes for plumbing pipes, electrical boxes, and sanitary fixtures. These core bits are intended for use with compatible drills or drill rigs and are optimized for use on brittle, glazed surfaces to reduce chipping and achieve neat edges.
Advantages
The Rockforce core bits are diamond-segmented to provide durable cutting performance and longer life compared with standard high-speed steel bits when used on ceramic and porcelain. Their design helps maintain stable cutting with minimal vibration, resulting in precise circular holes and reduced cracking or glazing damage. The variety of diameters in the set covers common installation requirements, reducing the need to purchase individual bits for each task.
Suitable for
 Drilling holes for plumbing pipes through ceramic tiles and porcelain stoneware
 Creating openings for electrical boxes and conduit on tiled surfaces
 Installing sanitary fixtures such as faucets, shower heads and drains
 Contractor and renovation work on bathrooms, kitchens and tiled facades
Key specifications
 Material tip: diamond-segmented cutting edge suitable for glazed surfaces
 Compatible use: designed for ceramic tiles and porcelain stoneware (gres)
 Set contents: seven core bits covering a range of diameters for common installation needs
 Diameters included: 33 mm, 53 mm, 67 mm, 73 mm, 83 mm
 Mounting: compatible with drills and drill rigs that accept corresponding arbors or adapters
 Intended cutting method: wet or dry cutting as allowed by the drill and material manufacturer’s guidance
How to use
Select the core bit with the appropriate diameter for the required opening and securely attach it to a compatible drill or drill rig using the correct arbor or adapter. Position the drill perpendicular to the tile and start at low speed to create a shallow guide groove, then increase speed gradually and apply steady, moderate pressure. Use water cooling if possible to extend tool life and reduce dust and heat; this is especially recommended for prolonged cuts or thicker porcelain stoneware. After cutting, clean the hole and inspect edges for any minor chipping before installing pipes or fixtures.
Ieteicamais lietošanas veids
 When using these core bits, follow safety guidelines: wear eye protection, a dust mask or water suppression, and secure the workpiece. Refer to the drill and material manufacturer's instructions for recommended speeds and cooling methods.
