A cordless jig saw is an excellent addition as it removes the cord that will constantly get tangled in your work Variable Pitch Bi-Metallic: Bi-metal construction boosts safety by eliminating the chance of shattering, so consider these a good step-up for dealing with slightly tougher materials or working for longer periods. Many boast hardened teeth of high speed steel for faster cutting, and variability lets you cut at different speeds according to your chosen material. Best suited to hardwood, plywood, non-laminated plastic, plasterboard, and non-ferrous metals (such as aluminium, zinc, and copper). Diamond-Edged: Showcasing a conspicuous absence of teeth, such hole saws are either coated or infused with diamonds. The hardness and durability is exceptional, so high heat and constant resistance are no obstacle. You’ll generally use them to drill through ceramic tiles. Though heat resistant, you should periodically cool them in water. Small Arbors: Have a shank size of 1/3-inch (8.75mm) and are used alongside hole saws with diameters between 14mm – 30mm (1/2 – 1 inch).

If your hole saw should become dulled, the relatively low cost of replacing the blade should be enough to dissuade you from sharpening. If you’re set on sharpening, you can use a hand file on each individual tooth, though a hand-held electric grinder will slightly cut down on elbow grease. A bench grinder also does the job, but extensive time and concentration is required – honestly, it’s largely advantageous to replace instead of re-sharpen. Storing

Welded Shank Soffit Cutter: A non-detachable arbor is welded to the base plate, and the saw is made from high speed steel with a variable tooth pitch. A wide diameter makes them seem tailormade for cutting vent holes in soffit boards, and they work well with plywood, metal, and PVC . When it comes to drilling holes for screws, most screws are tapered. And, to correctly set the screw, you need the diameter of the drill bit to match the shaft of the screw.A spade bit is the standard issue drill bit for putting holes in all shapes and sizes of wood. And, due to its inexpensive design, it’s an excellent tool for an occasional DIY’er. Let’s take a breath before diving into the particulars of using a hole saw to consider why exactly you’d want to.

Use Your Chisel: Grab a chisel and start cutting out as much wood as you can. This should let you go a little deeper. The hole saw is a large diameter, hollow drill bit with a keen cutting blade along the outer edge. Attach one to a power drill and it rotates at high speed, cutting precise holes into anything from bathroom basins to external walls. The depth of cut is limited by the hole saw’s cup-like shape, but a variety of bit types are available to work around varying requirements. Metal Cylinder Fixed Arbors: Said to have an ‘integral shank’, fixed arbors come attached to the hole saw blade. Using one means skipping any dismantling when you need to change saw size. Cut: With scrap wood securely clamped and marked, drill a fresh pilot hole into it and then continue as normal. Hole saw sets often provide an arbor adaptor. This straightforward threaded attachment fits over your drill bit and onto the collar threads of a large arbor, allowing users to attach a smaller hole saw to the adaptor’s threads.Coated: No teeth are used at all. Instead an ultra-hard material, usually tungsten carbide or diamond, coats the cutting edge. More of a niche tool, you’ll use coated hole saws to cut through heavy-duty metals, ceramics, and concrete. Unless you’re a professional, you’re unlikely to encounter the need.

Carbon Steel: Your basic general-purpose hole saw performs admirably for the DIY expert or enterprising home-improver. Though not the most durable, carbon steel hole saws are ideal for use with softer materials, including wood, non-laminated plastic, and plasterboard.
