Product Information

Ensure you cut directly down into the workpiece at an accurate perpendicular (90-degree) angle to the surface Specifics such as tooth design and overall shape will vary depending on what material the hole saw in question is intended for use on, but almost all products supplied by reputable hole saw brands will have a few traits on common. This is due to the width of the hole cutter bit, and the subsequently large amount of material being removed

They will generally extend anywhere from 10-30mm out beyond the open cutting end of the hole saw, and may also incorporate an ejector spring mechanism for helping to jettison plugs of loose material build-up Generally speaking, the teeth on most masonry hole saws (sometimes referred to as ‘core drill bits’) will be more widely spaced than timber versions, and often diamond-tipped teeth for extra hardness and cutting power. If the rear side and edges of the workpiece are accessible, clamping a scrap piece of timber behind it can give you a surface to drill your pilot hole into

Regardless of the material or surface you’re working on, never try to force the drill bit through any faster than it wants to go

Hole saw cutters for sheet metals are generally manufactured to be extra robust, and can withstand the much higher temperatures generated by cutting through a range of common metals such as (stainless) steel. These simple add-ons also help to protect the drill itself by stopping dust from directly entering the motor, especially when working overhead Another popular glass cutting tool offered by Dortech Direct Ltd is the manual glass cutter. This tool is designed for simple, manual cutting of glass, and is ideal for smaller cutting jobs or for use in areas where electricity is not available. The manual glass cutter features a cutting wheel that is advanced along the surface of the glass to make a score line. The glass is then snapped along the score line to create a clean, precise cut. At this point, the user may need to clear out the build-up using a screwdriver or similar ‘poking tool’You should never attempt to bore holes through masonry or heavier timber (anything over about 50mm) with a battery-operated drill Dortech Direct Ltd is a leading supplier of glass cutting tools for a wide range of applications. They offer a variety of high-quality glass cutting tools, including diamond glass cutters, to meet the needs of both professional and DIY glass cutters. Most multi-purpose, universal or bi-metal hole saws will get the job done on most types of timber and sheet wood - although for extra efficient and tidy cutting of engineered woods such as MDF, you may also like to consider a brand that offers carbide-tipped teeth.

Consider using an accessory such as a dust cowl to cover the hole saw bit while in use, and prevent excessive spillage of debris when boring out large holesBe aware that going in at a slightly off-centre angle - or hitting a nail while drilling - can cause very sudden and violent binding/jamming of the drill when using a hole saw
