Birth of Electric Drill

It was around 35,000 BCE, when the Homo Sapiens discovered the benefits of the application of rotary tools. Not fully developed, they consisted of a pointed rock being spun between the hands to bore a hole through another material. This rudimentarily led to the birth of Hand Drill, a smooth stick that was sometimes attached to flint point, and was rubbed between the palms. Many ancient civilizations used this. The earliest perforated artifacts, such as bone, ivory, shells and antelers found are from the upper paleolithicera.

One most great advancement in drilling technology, i.e. the Electric Motor led to the invention of the Electric Drill. The credit goes to the Arthur James Amot and William Blanch Brain, who belonged to Melbourne, Australia.  They patented the electric drill in 1889. In 1895, the first portable handheld drill was created by brothers, Wilhem & Carl Fein, from Stuttgart Germany. In 1917 the first trigger switch, pistol-grip portable drill was patented by Black & Decker. This was the start of the modern drill era. Over the last century the electric drill has been created to the variety of types, and multiple sizes for an assortment of specific uses.

Hand tools

A variety of hand-powered drills have been employed over the centuries. Here are a few, starting with approximately the oldest:

·         Bow Drill 

·         Brace & Bits

·         Gimlet

·         Hand Drill

·       Breast Drill, similar to a Hand Drill, it has a flat chest piece instead of a handle

·         Push Drill

·         Pin Chuck, it’s a jeweler’s drill

Accessories

Drills are often used simply as motors to drive a variety of applications, in much the same way that tractors with generic PTO’s are used to power ploughs, mowers, trailers, etc.

Accessories available for drills include:

·         Water pumps

·         Nibblers for cutting metal sheet

·         Rotary sanding discs

·         Rotary polishing discs

How Diamond Saw Blade Works

Each and every Diamond blade has its own specific and unique application and every blade reacts differently under various circumstances. Being found in hundreds of different varieties, types, bond types, and manufacturing methods, they have their own use. Blades which are ultra thin & of high precision, they are used for Slicing, Dicing, Wafering, Cut-off, Singulation, Grooving, Slotting, Cross Sectioning, Sample Preparation, Gang Sawing, Slabbing, Rough Cutting applications.

In simple words it is a cutting tool which has exposed diamond particles captured in a metal matrix each with a small cutting edge.

§  Diamond blades are usually made with a steel core or completely impregnated with diamond.

§  During the diamond cutting operation, the surface speed may reach 30 m/sec, if using a high speed diamond cutting saw.

§  The cutting action is performed by accumulation of small chips scratched out by the numerous diamond particles impeded in the bond.

§  The number of cutting edges which is determined by the number of diamonds makes up the structure of the diamond blade, along with its matrix, metal or nickel bond. 

§  The size of the diamond particle will have a direct result in the size of chip we can obtain. The thickness of the diamond blade (diamond particle plus matrix) will determine the width of the cut.

Therefore, diamond blade selection along with feed rate, cutting speed, and depth of cut will ultimately determine your diamond sawing success.

Our diamond blades have the following advantages:

·         Minimal Chipping

·         Faster Cutting Action

·         Minimal Cutting Noise

·         Minimal Loss of Material
