About this deal

Hole saws seem misleadingly easy to use. It’s no mere matter of choosing a spot before pressing down with your drill, and practice must make perfect until you’re confident. During your first few attempts, try using a practice workpiece. Cut: With scrap wood securely clamped and marked, drill a fresh pilot hole into it and then continue as normal. As you’re browsing, you might consider seeking an arbor with a spring placed over the drill bit. These are known as ejector springs – they contract as you drill and then eject the slug (the cut segment) after the hole has been made. 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. Deep Cut Variable Pitch Bi-Metallic: Not named through coincidence, the deep cut variable pitch bi-metallic hole saw drill will boast a cut depth up to 42.5mm. Otherwise, it retains the characteristics and benefits of the standard bi-metallic.

Blades with a lower TPI cut faster, but they do tend to tear at fibres to produce a more ragged edge. Use Your Chisel: Grab a chisel and start cutting out as much wood as you can. This should let you go a little deeper. Understand TPI as a measure of tooth frequency along the blade. For example, 18 TPI means 18 teeth per inch, so that tooth frequency is higher than that of a 16 TPI hole saw. TPI numbers vary, but they stay within the general ballpark of 20 to 2. Let’s take a breath before diving into the particulars of using a hole saw to consider why exactly you’d want to. Other tools can cut holes, so what makes a hole saw the go-to among professionals? 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

How to Care for Your Hole Saw

Versatility: A hole saw achieves a greater variation of hole sizes than rival tools – they are particularly valued for cutting large diameter holes. Blades with a higher TPI will cut slowly, but, less likely to tear at the fibres of your material, they also cut smoothly.

A workman’s staple, the hole saw is a tool you’ll encounter as you start to flex your DIY muscles and branch out into more interesting challenges. They’re used to cut perfectly round holes in a variety of materials. Wood and plaster are common workpieces, but metal, glass, ceramic, concrete, and stone still fall to the hole saw. 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). You’ll also want to pay attention to the pitch of teeth and their TPI (Teeth Per Inch) rating, so let’s break down the impact of each factor. Pitch Continue Cutting: Once the wood has been cleared, realign your saw and continue until you reach the required depth or make a through-hole. Tungsten Carbide Tipped: Tungsten carbide tipped teeth deliver fast cutting action and outstanding durability, ideal for those who expect to use their hole saw frequently and for extended periods. Often used as the construction industry’s multi-purpose option, they cut through all woods, plastics, tiles, and metals. Perhaps not quite necessary for personal use, but undeniably nice to have.

Types of Hole Saws

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. Screw Hole Saw and Arbor Together: Screw the hole saw onto the arbor thread, not stopping until it feels as tight as possible. If adjustable, the arbor should protrude past the teeth by around 3/8 inch and then tighten using the set screw. A variable pitch breaks the sawing rhythm; that might sound like a bad thing, but it inhibits vibration for a smoother cut, reduced blade wear, and lower noise levels. Chips and dust eject easily to reduce the chance of clogging or overheating.
