They are also easy to use, even for those with limited experience, and are suitable for a wide range of cutting applications. As with most power tool accessories, the key to choosing a high-end, well-made hole cutter is to look out for a combination of robust construction, quality materials and accurate, tidy machining. 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.
A set of three tapered drill bits for drilling and enlarging holes in a variety of materials, especially thin sheet metal, fibreglass, upvc and most plastics. The boring edge usually consists of a circular arrangement of sharp teeth, machined around the full perimeter of the open cutting end of the bit. They’re generally quite inexpensive and widely available, and they feature prominently in both professional and hobbyist tool boxes across a broad range of industries and applications. 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.Rather than having jagged or crenellated teeth protruding from the cutting edge, these types of hole saws instead feature a flat rim that’s coated with a hard, abrasive material such as diamond or carbide. Hellers HSS, bi-metal hole saw kit is a great choice for numerous tradesmen, and electricians in particular. This helps to reduce friction between the teeth and the work surface, and in turn means less user force is required to break through a workpiece, putting less strain on the drill’s motor as the hole is drilled.
As implied by the name, a hole saw is made to cut a circular hole of much wider gauge through a workpiece than standard drill bits can create on their own. This wider spacing makes it easier for removed material to fall away from the hole saw edges, helping to prevent clogging and binding.

Available for purchase in single units or as part of a multi-piece hole saw set, these types of hole cutters are highly versatile and commonly used items of DIY kit. Some hole saw designs also feature an arbor or pilot bit (either built-in or removable), which protrudes through the hollow centre of the hole cutter.While these sorts of tough working conditions don’t often cause an immediate or catastrophic failure in other types of hole saw bits, they can degrade the product relatively quickly if it wasn’t designed for the job, making them much less cost-effective over time.

This Heller HSS Bi-metal Hole Saw is perfect for creating clean, circular holes thanks to its ingenious precision manufacturing. While collections of guidelines are seldom any match for hands-on experience in this department, there are some fairly universal techniques and basic user tips that all hole saw operators should bear in mind when approaching a new job.
The most familiar style of hole saw you’ll generally find in product catalogues is based around the standard cylindrical metal tube, with a shank at one end for insertion into a drill chuck.
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.
