Vacuum Brazed Diamond Holesaws

These special diamond hole saws benefit from fully exposed diamonds that are vacuum brazed directly to the cutting edge. Vacuum brazing is a material joining process which offers significant advantages in terms of cleanliness, joint strength and integrity making the hole saws durable and convenient to use when drilling a vast variety of materials. They are especially good for drilling porcelain.

Features: Fully exposed diamonds joined by a vacuum brazing process, 10mm hexagonal fitting and pilot drill (supplied) to aid start up.

Suitable for use on: Bricks – Class A Engineering, Bricks – Class B Engineering, Bricks – Standard Facing Bricks, Cement Fibre Board, Clay Products, Composite Cladding and Panels, Concrete – Roof Tiles, Concrete Blocks – Lightweight 3 to 7 Newton, Concrete Blocks – Medium Density 7 to 12 Newton, Concrete Blocks – Solid Density 12+ Newton, Earthstone Worktops, Fibreglass, Glass Reinforced Plastic (GRP), Granite – Blocks and Worktops, Laminated Products, Limestone, Marble – Blocks and Worktops, PE Polyethylene Plastic, PP Polypropylene Plastic, Quartz Worktops, Sandstone – Abrasive, Sandstone – Indian, Tiles – Ceramic, Tiles – Granite, Tiles – Limestone, Tiles – Marble, Tiles – Porcelain, Tiles – Slate.

Usage Advice: Use the pilot drill to aid start up. Before drilling porcelain, pre-drill a 6mm pilot hole using a diamond tile drill. For best results when drilling tiles, apply a fine mist of water via a hand-held spray bottle. Do not use unnecessary pressure, the weight of the machine is sufficient. Using a slight oscillating motion whilst drilling can increase speed on some materials. Use at speeds between 800 – 2000rpm. For harder tiles use a slower rpm / for softer tiles use a faster rpm.

Standards: EN13236: European Standard that regulates the safety requirements for super abrasive (diamond) products
