Product Information

If you want to drill a hole clean through a workpiece, be aware that going directly from one side through to the other with a hole saw can create a lot of ‘blowout’ (material tearing) on the reverse side 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 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 Ensure you cut directly down into the workpiece at an accurate perpendicular (90-degree) angle to the surface

Be 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 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. More advanced designs might feature an ejector spring for this purpose, usually wound around the central arbor if one is present - you can also buy ejector springs (pictured on the right) as an aftermarket hole saw accessoryIn addition to these basic glass cutting tools, Dortech Direct Ltd also offers specialized glass cutting tools, such as circle cutters, glass scoring tools, and glass pliers. These tools are designed to provide specific cutting solutions for unique cutting applications and can be used in conjunction with other glass cutting tools to create precise and efficient cutting solutions. In many cases, it’s possible to do this via the handy ‘speed slots’ that many brands cut into the side walls of their hole cutters for this very reason

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 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. 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 holes This is due to the width of the hole cutter bit, and the subsequently large amount of material being removed These simple add-ons also help to protect the drill itself by stopping dust from directly entering the motor, especially when working overhead

A hole saw or hole cutter is a specialist type of drill bit, designed to allow the user to bore out a circular hole of wider diameter than most standard bits would typically create.

At this point, the user may need to clear out the build-up using a screwdriver or similar ‘poking tool’ You’ll find these widely available on products released under many leading brand names - the question of who makes the best circle cutter bits is a subject for much debate, but common nominations for the title often include both Starrett hole saws and Lenox hole saws. You should never attempt to bore holes through masonry or heavier timber (anything over about 50mm) with a battery-operated drill

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.
