Bosch DB741C 7-Inch Diamond Blade

The Bosch DB741C 7-Inch Diamond Blade is a standard blade for circular saws. It is manufactured from high carbon steel with a hardness of 58 HRC (hardness grade).

The blade’s cutting edge measures 1/4″ wide at its widest point and 3/8″ thick. Its overall length is 2-1/2″.

It is made up of two parts: the handle and the tang. The handle consists of a single piece of stainless steel with a black finish.

It measures 4-3/4″ long when closed and weighs approximately 5 oz. The tang includes three rivets that secure it to the handle, which are held in place by four small hex nuts located near their ends. The tang is secured to the handle using two screws.

A set screw secures the tang into place and another holds it onto the handle. A spring-loaded clip slides over the top of the tang to hold it in place while opening or closing the blade.

The clip has a flat surface on one side so that it can slide along a smooth surface without slipping off completely.

The blade itself measures 1-5/16″ wide at its widest point and 3/8″ thick. It has a hard, shiny surface which is created when the blade is quenched in oil at high temperatures.

The cutting edge is made by heating the steel to over 1600 degrees and then quickly chilling it in water.

This creates a very hard edge that resists dulling and chipping better than blades with a softer edge. The hard edges retain their sharpness much longer than softer ones, but they are more likely to break.

The tiny teeth along the cutting edge are measured in a unit called grit. The higher the number, the smaller and sharper the teeth.

A blade with higher grit will cut faster than one with lower grit, but it will also dull faster. This blade has a grit of 325, which is a good balance between speed and longevity.

These saw blades are suitable for use on green or cured concrete, brick, stone, and block. They are also suitable for asphalt and plywood.

Additional Features

The blade’s bright, shiny appearance is created by quenching the very hard edge in oil at high temperatures. The blade is then tempered so that it can be used safely without breaking.

The parting surface of the blade has no teeth along its cutting edge. This smooth surface prevents the blade from being pinned in the material and help prevent it from getting stuck in the material.

The teeth are angled at 50 degrees and extend below the surface of the blade. They are made by a laser that instantly heats the edge and cools it quickly.

This process allows the teeth to achieve a sharper edge while using less metal. After production, the teeth are carefully set into the blade’s surface with great precision.

The blade uses grain oriented steel reinforced with titanium. This specialized metal composition allows it to retain its strength at high temperatures and resist wear and chipping.

After the teeth are fitted, the metal is heated to over 1500 degrees and then rapidly cooled. This causes the metal to crystallize and become much harder.

After quenching, the blade is still soft enough to allow it to be ground and machined with a high degree of precision. The highly polished surface helps the blade cut by sliding over the material instead of ripping or tearing it.

The handle has a durable inner layer that is surrounded by a thick rubber layer. This cushions the operator’s hand from the force of cutting and helps prevent blisters.

The outside of the handle is plastic with molded finger grips and a pattern to prevent slippage.

Since the blade and handle are made of solid metal, they can be recycled once you are finished with them. This reuse system allows more resources to be available for future products and reduces waste.

Metal recycling in the United States is not as efficient as it could be. Most scrap metal from construction and manufacturing is still being shipped to China and other countries for recycling.

The US needs to build more facilities to process this metal before it can be recycled.

Service life: This Saw has a life-time warranty for home use.

Made in USA

This product was made in the USA mostly by American companies using American labor. It does not count as an American export but it helps the economy and creates jobs here.

Also this product is guaranteed for life, so if anything happens to it you can return it and get a replacement. You can’t do that with those cheap imported saws!

(Note: This product is not actually made from wood).

Material: The body of the saw is made from steel that is more durable than other steels and can remain sharp for many years. This material makes it easier to maintain a sharp edge but it can still bind in the cut if not treated properly.

The handle is molded plastic.

Care: The blade needs to be kept clean and sharp at all times. The teeth should always be kept straight and not at an angle when cutting.

The saw should not be used on materials that are harder than the teeth or the teeth will quickly become dulled and ruined. The material can be recycled to a store that recycles metals, you get money for your old material!

History: The circular saw is a common type of saw that can be used in many different ways. It was first developed in 1814 by a man named John Shaffer.

The saw was made by fitting small, sharp teeth onto a spinning circle of wood. The circular motion made cutting much easier than it had been with traditional hand saws.

The hand saw was used by having two people. One would hold the board tight while the other would push the saw through.

It was easy to apply an even amount of pressure and the circular saw could cut the board much more quickly.

In 1836, a man named Samuel Miller created an improved version of the circular saw. He fitted small, sharp teeth onto two interconnected wheels.

The operator pushed the saw through the board while it rotated the wheels with small levers. This made cutting much faster and easier. This type of circular saw is still used in many small construction projects.
