Product Information

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. 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.

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. Cut: With scrap wood securely clamped and marked, drill a fresh pilot hole into it and then continue as normal. Pitch refers to the distance between the point of two teeth (serrated) or the middle of two teeth’s gullets (gulleted/square). A variable pitch hole saw varies that distance, while a constant pitch hole saw maintains the same distance. 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. Serrated Saw Teeth: Typically set at a 60° angle to allow a penetrating bite into the material being cut, saw teeth are far and away the most common cutting edge. Use saw tooth hole saws for wood, plaster, softer metals, and plastic.Clamp Some Scrap: Take some scrap wood and clamp it to your workpiece to provide a solid point on which to secure your drill bit. 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?

Versatility: A hole saw achieves a greater variation of hole sizes than rival tools – they are particularly valued for cutting large diameter holes.Adjustable: Adjustable hole saws allow multiple sizes of holes to be made with the same machine. Portability is improved since everything is contained within a single unit, and you’ll be able to work with various materials without changing up. 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.

All in all, you’ll find yourself fluent in hole saw by the time you finish reading this post. What is a Hole Saw?Multi Hole Saw: Designed to be used for cutting a range of different diameter holes, the multi-hole is notoriously undiscerning when it comes to material. Wood, non-laminated plastics, plasterboard, chipboard, plywood, and non-ferrous metal (except stainless steel) can all be cut through. 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 Hole saws pose potential danger, so knowing when and how to use them is key. Whether you’re cutting through wood or dealing with ceramic, you’ll start by properly attaching the hole saw to the drill. 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.
