Making Straight Cuts with a Circular Saw
For starters, select the depth of your cut by setting the blade length below the base. As a tip when cutting wood, position its good side facing down to keep scratches and other material deformations at bay.
Secondly, draw a precision line right where you intend to cut. Then, align your circular saw on the line and power up the motor. Ensure you bring the saw to full speed before you start slicing through the material. Upon reaching the highest level, make contact between the material you’re cutting and your saw.
Thirdly, refrain from forcing the tool. Doing so jams the saw blade. If this occurs, slowly but carefully take the saw back and approach the cut slower to usher in, accurate and clean cuts on any material you require.
Safety Measures and Practices
When working with circular saws, ensure you:
- Always wear eye protection. During aggressive cutting, small pieces of wood fly up into the air and land on your face. So, there’s a likelihood of sustaining injuries to your eyeballs or developing an eye infection without the use of durable safety eyewear.
- Turn off your circular saw when making adjustments to it to avoid the risk of sustaining adverse injuries.
- Avoid carrying your tool around with your finger resting on the saw’s trigger as you may unintentionally power it on and sustain a deep a cut.
Can You Cut Material without A Table?
In a nutshell, yes! But, we recommend always using a table when slicing materials using a circular saw. If there’s no table lying around, you’ll need to get creative on how to secure the material.
For instance, you can clamp it down as one of the common ways. Avoid holding down the material with one hand and operating your saw with the other. Doing so leads to the tool slipping from your hand, in turn damaging the material and injuring you.
What Features Should You Consider?
When purchasing a battery-powered circular saw, consider the following criteria.
- Rafter Hook: It’s ideal for hanging on a multitude of objects as opposed to setting the saw on the ground.
- Rail Compatibility: It grants the saw the uncanny ability to attach onto a track more accurate cuts.
- Dust Port: It provides a link to a vacuum for easier cleanup.
- LED Lighting: It enhances visibility on the blade area, making your cutline clear as day.
- Brushless Motor: It delivers optimum runtime, performance, and longer life.
- Cutline Blower: It utilizes exhaust airflow, thus veering sawdust further from your cutline.
- Trigger Safety Design: Some gravitate towards a push-down style, whereas others opt for a push-in. So, it boils down to your preference.
- Magnesium Components: These diminish the weight of circular saws without compromising on their strength.
- Electronic Brake: It’s an excellent safety feature that brings the blade to a halt, in a jiffy.
