Eye Protection and Mouth Guard: To prevent dust or splinters getting in your eyes or being inhaled. Versatility: A hole saw achieves a greater variation of hole sizes than rival tools – they are particularly valued for cutting large diameter holes. 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).

That covers the basics, but what if you need to drill holes deeper than your hole saw allows or widen an existing hole?

Types of Hole Saws

Drill Your Pilot Hole: Used to guide the saw, this goes right at the centre of the hole you wish to cut. As you drill, keep the bit level. If your workpiece is freestanding, take the time to secure it to prevent any spinning or other movement. 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.

Leaves the Core Intact: A hole saw works without needing to cut up the core of your workpiece, a notable advantage over twist drills or spade drills, especially when dealing with larger holes.

Safety Equipment When Using a Hole Saw

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. 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. 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

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. 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

Remove Slug: The slug is just an easy term for the waste material that collects in your hole saw. If you have an ejector spring arbor, it should pop right out – otherwise, dig it out manually. 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. Here’s where things get interesting. The metal cylinder of each hole saw culminates with an edge that uses either serrated saw teeth, gulleted/square teeth, or ultra-hard embedded materials to cut through your workpiece.
