Hole Saw Buying Guide

A hole saw (also styled holesaw), also known as a hole cutter, is a saw blade of annular (ring) shape, whose annular kerf creates a hole in the workpiece without having to cut up the core material. It is used in a drill. Hole saws typically have a pilot drill bit (arbor) at their center to keep the saw teeth from walking. The fact that a hole saw creates the hole without needing to cut up the core often makes it preferable to twist drills or spade drills for relatively large holes (especially those larger than 25 millimetres (1.0 inch)). The same hole can be made faster and using less power.

The depth to which a hole saw can cut is limited by the depth of its cup-like shape. Most hole saws have a fairly short aspect ratio of diameter to depth, and they are used to cut through relatively thin workpieces. However, longer aspect ratios are available for applications that warrant them.

Cutting with a hole saw is analogous to some machining operations, called trepanning in the trade, that swing a cutter analogous to a fly cutter in order to achieve a similar result of annular kerf and intact core.

Types of Hole Saws

  • Adjustable: An adjustable hole saw consists of a number of thin metal saw blade-like strips, and a flat disc with a large number of grooves in one side and a shank on the other. By snapping the blades into different grooves on the disc, a hole saw of a wide variety of sizes can be constructed.
  • Circle cutter: Another type of adjustable hole saw, also called a circle cutter, is formed by having one, two, or three adjustable teeth on a platform with a pilot bit. To cut out a hole of any size, the teeth need only be adjusted to the proper position. This type is available in sizes up to 300 mm (1 ft) and larger, and can be used to accurately cut large circles.

Most Essential Things about Hole Cutter?

Looking into the usability, performance, sharpness, and most importantly, the customer’s feedback, I’ve tried to gather some of the most prominent choices you can get these days.

Choosing a crater for electrician, plumber, carpenter, the DIY worker would need your attention and courtesy over the requirements you specifically have. For what purpose and for how long would you want one? Is durability essential to you more than having too many size options? What about the price, are you okay with paying for an expensive one for better quality? Or maybe a reasonable option would be even better if you can save a few bucks.

These hole saw reviews would succeed when a buyer is benefited from both side product and money. All of these questions have an answer that must be based on your current situation and wants from the clipper cutter kit. Think about it a bit and choose thoroughly the ones that suit the maximum.

What’s the Largest Size Hole You Need?

Hand holding hole saw The first thing to ask yourself is what size hole do you need? If you’re drilling a hole for a specific purpose, this shouldn’t be too difficult of a question to answer. But if you’re just getting it to have for the next time you need to make a perfectly round hole, then it might be more difficult.

When using your hole saw kit to make holes for plumbing, a common use, you’ll rarely need any hole saws over 2½ inches since most household plumbing is smaller than this. For this reason, the largest bit in most hole saw kits is 2½ inches.

But if you have a specialty use that requires a hole that’s larger than this, you’ll need to choose a kit that has hole saws large enough to accommodate your needs. If the kit won’t make a hole big enough for your purposes, then it won’t do you much good.

Try to determine the largest hole you might need to make, and choose a hole saw kit that has bits at least that large.

Q: Can a hole saw cut metal?

A hole saw will cut through thin-gauge metal materials like aluminum and steel. When possible, use oil or water to lubricate the surface to prevent the bit from overheating, which can damage the bit.
