Why Use a Hole Saw?
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.

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. PitchAs 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. Despite the name, this tool looks more akin to a drill bit than a saw – in fact, its cutting edge rests at the end of a large diameter cylinder, and this is spun on a power drill to cut through your chosen material.

Versatility: A hole saw achieves a greater variation of hole sizes than rival tools – they are particularly valued for cutting large diameter holes. 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. The chance of injury falls significantly when you don the right safety wear and employ the proper safety equipment. Hole saws don’t require much, but what they do require is vital. 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.
How to Use a Hole Saw Perfectly
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. 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. 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. Eye Protection and Mouth Guard: To prevent dust or splinters getting in your eyes or being inhaled. We’ve covered how the individual components of a hole saw can differ, but more important is the variation between hole saw types. There are plenty from which to choose, and your decision should be based around:
