Any portable saw you buy for your home or shop should be capable of cutting a 2 x 4 piece of wood at a 45-degree angle. In general, saws that have a blade diameter of 7 or more inches are good choices. Using a saw safely should be of primary importance. In this article I'll cover the basics on saw selection and safety practices.
A number of considerations have a bearing on your decision when buying a circular saw. Do you want powered or cordless? Does the saw come equipped with a depth adjustment, which enables you to make shallow cuts when required; an angled adjustment for cutting miters and bevels; and a ripping fence, which guides the saw when you want to rip a board to a specific width? It should have an automatic spring-loaded blade guard that retracts as the blade enters the work area, and then covers the exposed part of the blade as soon as the cut has been completed.

Since most present-day saws have all these features, your final choice often depends on how conveniently a saw operates and how easily the adjustments are made. Another major consideration should be the weight of the tool. Think about how long you intend to use it in any one stretch of time. Large-sized adjustment nuts are a worthy consideration, as is an easy-to-grip handle on the blade guard. In addition to the saw handle, which contains the trigger starting switch, a knob on the end of the motor housing is convenient as an extra handle for awkward situations. This feature is not essential with smaller saws.
Safety Practices
When using any portable saw, always be sure that the work to be cut is firmly supported, or held, so that it will not shift during the cut. Start the saw before the blade enters the work and guide it straight along the cutting line. Veering can cause jamming, stalling, possible motor damage, or even worse the entire tool may jump or hop out of the wood creating the possibility of a serious injury. Be especially careful not to let the saw veer when using a masonry-cutting blade. Blade breakage could result and the flying shrapnel may cause injury. If a long piece of wood is to be cut, it should be supported by a helper. It must not be moved during the cut in such a way as to close the cut and bind the blade. Keep a firm grip on the saw with your right hand, and keep your left hand well away from the saw. Make certain also that the cord is well out of the way so it will not be cut by the blade.
Maintain a strong grip on the saw to keep it from tipping or dropping at the end of the cut. Keep your hands clear of the blade during the time required for it to come to a complete stop. It's also a good idea not to touch the blade immediately after it stops as it's probably hot enough to burn you. Never adjust the saw without first disconnecting the power cord.
Picking the right circular saw is largely a matter of personal choice. Using the tool safely is a matter of common sense. Pick wisely and use it even more wisely.

Black Friday Bosch DDS180-02 18-Volt Compact Tough Drill Driver with 2 1.3Ah Batteries Overview
Includes 18V Cordless Lithium-Ion Compact Tough 1/2-in Drill/Driver - DDS180-02, (2) 18V Slim Pack Lithium-Ion 1.3 Ah Batteries, 30 Minute Li-Ion Charger, Carrying CaseBlack Friday Bosch DDS180-02 18-Volt Compact Tough Drill Driver with 2 1.3Ah Batteries Specifications
Ready for all materials from wood to metal, the compact yet powerful Bosch DDS180-02 Compact Tough 18-volt lithium-ion 1/2-inch drill/driver's 7-inch head length is the smallest in its class, yet it delivers top heavy-duty drilling performance. It works with all Bosch 18-volt lithium-ion batteries, and this kit includes two 1.3 Ah Slim Pack batteries to help keep things light.
Fast Speeds, High Torque, and Durable Construction
The DDS180-02 is optimized to worke at two speeds--one for high-torque applications (0-500 RPM) and one for high-speed applications (1,700 RPM)--and it provides a maximum of 600 inch-pounds of torque. The 4-pole open-frame motor and newly developed gearbox provide exceptional power for such a compact drill/driver. The 18+1 clutch settings included in this Compact Tough model and a variable-speed trigger help you match the best speed to the job, so you can achieve precise results. It can drive 500 screws per charge using the BAT619G 3.0 Ah HC battery (not included).
Balanced Design and Easy Bit Changes
This drill/driver's Durashield housing is constructed with ABS/nylon composite, which makes the housing flexible on impact. Unlike competitive tools, which use a conventional plastic housing, Durashield will not crack and can easily withstand 10-foot drops.
The ergonomically designed handle and soft-grip wrapped housing offer a comfortable fit for extended working time. The DDS180-02 comes complete with a single-sleeve 1/2-inch auto-lock chuck for one-handed bit changes, as well as increased drill-bit capacity for versatility. And for even greater convenience, LEDs provide illumination when you are working in dark or enclosed areas.
Flexible Power System
Like all tools in Bosch's 18-volt line, this drill/driver can be used with either a 1.3 Ah Slim Pack battery (model BAT609), a 2.6-Ah Fat Pack battery (model BAT618), or a 3.0 Ah Fat Pack HC batter (model BAT619G). If you're looking for a lightweight option, the Slim Pack is the perfect choice. If longer runtime is what you need, the Fat Pack will do the job.
ProVantage GuaranteeThe DDS180-02 comes with the ProVantage three-year protection plan, which guarantees two years of battery protection and one year of tool protection. Under this plan, you can receive two years of free battery replacements, tool replacement for one year, and a free tool repair package for the second and third years. |
