## Summary description

Diamond hole saw GRAPHITE 82×8×75 mm (model 57H878) — a cutting tool designed for drilling circular holes. Key parameters: 82 mm diameter, 8 mm cutting height, 75 mm overall length. Suited for cutting hard materials where diamond grit is required, such as ceramics, porcelain, tiles and some stone. Used with compatible drills and appropriate cooling to extend life.

## Long description

The Diamond Hole Saw GRAPHITE 82×8×75 mm model 57H878 is a diamond-grit cutting core designed for drilling precise circular openings in hard brittle materials. With an external diameter of 82 mm, a diamond cutting height of 8 mm and a total length of 75 mm, this hole saw is optimized for controlled cutting in ceramics, porcelain, glazed tiles and some types of natural stone. It is intended for use on compatible rotary drill rigs or drill stands with appropriate speed and coolant supply.
Advantages
The diamond segment provides aggressive but controlled cutting performance and extended durability when used with water cooling. A narrow cutting height reduces material waste and helps maintain hole roundness. The 75 mm overall length gives sufficient reach for common tile and slab thicknesses while ensuring stable attachment in standard chucks or adapters. The design minimizes chipping on glazed surfaces when proper drilling technique is applied.
Suitable for
Drilling circular holes in ceramic wall and floor tiles
Cutting openings in porcelain and glazed sanitary ware
Creating holes in thin to medium-thickness natural stone slabs
Installing plumbing or electrical fixtures through tiled surfaces
Key specifications
Outer diameter: 82 mm
Diamond cutting height: 8 mm
Total length: 75 mm
Cutting material: diamond grit bonded segment
Recommended cooling: water cooling during operation
How to use
Secure the hole saw to a compatible drill or drill stand according to the tool manufacturer's instructions. Mark the center point of the hole and begin drilling at low speed to establish a guide groove; increase to moderate speed once the segment is engaged. Apply steady, light pressure and maintain continuous water flow or periodic cooling to reduce heat and prolong the life of the diamond segment. Avoid excessive lateral force and allow the tool to cut gradually through the material. After completing the cut, withdraw the core and remove any debris from the segment.
Usage recommendations
For best results use with a variable-speed drill or drill stand, maintain water cooling throughout the cut, and use light, consistent feed pressure. For glazed or fragile surfaces, start with a guide or pilot mark and keep speeds low to prevent chipping. Replace the hole saw when cutting efficiency noticeably decreases.
