Types of Saws and When To Use Them
12 / 15
Chainsaw
The motor in a chainsaw drives a chain with cutting teeth around a bar that extends in front of the handle. Homeowners wary of gas-powered chainsaws may prefer corded and cordless models with less power that are safer to use.
A chainsaw is a must-have for anyone who does a lot of yard work or who cuts their own firewood. A small chainsaw mounted on a pole for cutting high branches is known as a pole saw.
Uses
- Pruning trees and bushes;
- Cutting logs into smaller pieces;
- Making crosscuts in heavy lumber.

Hole Saw
When you need to cut a perfect hole of a specific diameter in wood, plastic or metal, you need a hole saw. It’s attached to a pilot bit that fits into a power drill. The bit allows you to drill a centered hole exactly on a mark. Hole saws for wood have teeth while those for metal feature abrasive cutting edges.
Uses
- Sawing holes in doors for door knobs and deadbolts;
- Making holes in acrylic and fiberglass shower stalls for faucet handles, spouts and shower heads;
- Cutting holes in framing for pipes and wires.

Rotary Saw
Instead of a blade, a rotary saw (AKA a spiral saw, rotary cutter or the brand name RotoZip) has cylindrical cutter that looks like a drill bit. The cutter fits into the chuck of the tool, which has a powerful motor that spins it at high speeds.
When the cutter is spinning, you can poke it directly into a surface and cut a shape more quickly than you can with a keyhole saw or jigsaw. Many rotary saws are cordless so you can use them anywhere.
Uses
- Making quick cutouts in drywall for electrical boxes;
- Sawing holes and notches in wood paneling;
- Cutting intricate patterns in wood and other materials.
