Buy Drill Bits Online India


Most cobalt bits contain either 5% cobalt (M35) or 8% cobalt (M42). The higher the percentage of cobalt the more brittle the drill bit will become, therefore 8% cobalt bits are better suited for controlled drilling situations, such as the use of a pedestal drill where both perfectly straight drilling and controlled drilling speed can be achieved.

For most non production drilling applications, and particularly when drilling is been performed with a hand drill M35 or 5% cobalt drills would be the preferred option as these are less brittle. However 5% cobalt drill bits have superb red hardness and abrasion resistance and will therefore perform superbly in the drilling of harder metals and alloys.


In order to ensure our products are of the highest standard we have had them tested by two of the worlds leading testing houses. Our cobalt drill bits have been tested for hardness and have received a certificate of hardness. Similarly we have had our metal cutting paste tested in order to determine its extreme pressure capabilities. We have the video of the testing and the testing report available.


1. The bits are manufactured out of high speed steel which allows the bits to handle higher temprature and pressure. Steel allows the bits to function at maximum strength and it also prevents them from corrosion. Using steel as a base for the construction thus ensure great quality and durability. 2. The drill bits and screwdriver bits come in a packaging of 5pcs together. This set alone can work well for a wide range of applications. 3. The bits are available in 5 different sizes which include the following sizes: 4, 5,6,8 and 10mm. 4. The masonry bits are best suited for drilling related jobs. These are extensively used at the construction site to drill through concrete, natural stone and other hard materials. 5. The set comes with clear demarcations of the measurements which allows the user to easily identify the right bit size that is required for the job. 6. The drill bit set is available in silver color.


This Hilti 2170687 HSS-R 14X160 mm Drill Bit has a 118 tip angle and is designed to be used with hard materials like concrete. This strong quality steel class-type standard drill bit features a smooth shank and a 118 tip angle for increased durability. Hilti twist drill bits feature a unique and innovative design with up to 3x the lifetime performance of ordinary twist drills. Features include Strong quality steel construction, standards-compliant 118 tip angle, and class-type standard end connection. Hilti Drill Bits are designed for drilling holes in materials such as wood, concrete, block, and brick. This drill bit is made from strong quality steel that ensures maximum strength and durability. It is also designed with a special coating to resist wear and reduce friction, making it suitable for use on rotary hammers. Hilti Drill Bits are manufactured from high-quality steel. These bits feature a high spiral density, which allows for a smooth rotation with no resistance and better performance. The houndstooth tooth pattern provides improved chip clearance, reducing the risk of premature dulling. Semi-chisel tip-cutting edges provide optimum hole quality. Hilti twist drill bits feature a drag reduction system which creates less heat than other drill bits. This allows for increased speed, longer tool life, and higher stability in soft and hard materials.


A drill bit is a tool used to cut through materials and surfaces of various kinds. A drill bit is firmly affixed to a drilling machine; when this drill device is powered on, it drives the drill bit affixed to it in return. Drill bits come in various sizes and kinds which enable them to make holes and orifices of different dimensions and shapes; they do so by rotating about their axis as the operator presses the tip of the bit against the surface or material to be worked on.


Different types of drill bits are used on different kinds of drilling machines. Some popular types of drill bits include carbide dream drills, centre drills, diamond core drills, hand drills, masonry drills, MQL type carbide dream drills, NC spotting drills, parallel shank drills, shell drills, slot mortise drill bits, solid carbide jobber drills, solid carbide stub drills and taper shank drills.


A twist drill bit is the one that has a long cylindrical shaft with flutes running along its length in a helical manner; the shaft ends in a sharp cutting point. The flutes of this type of drill bit are so equipped as to be able to clear the orifice being drilled off any accumulating swarf. Centre drill bits are used by metalworkers to drill out a tiny hole which is to be subsequently drilled into a conical indentation by a bigger drill bit so as to be able to accommodate a lathe machine. Diamond core drill bits, also popularly referred to as diamond hole saws, are ideal for wet and dry drilling applications and are used at comparatively lesser speeds to allow the diamonds studded in the metallic segment to work its way through surfaces.


Besides drills and drill bits, you might want to have a look at quite a few other equipment on display at the tooling and cutting window of Industrybuying; try end mills, taps, milling cutters, standard carbide burrs, dies, reamers, ejecting drill drifts, circular saw addas, rounding cutters, taper edge wheels, cutting blades, ratchet pipe threaders, side and face cutters and insert and carrier bodies, to name a few.

That brings us to tungsten carbide, more commonly referred to as carbide or sometimes cemented carbide. Think of it as cobalt on steroids. It's been around for nearly one hundred years but didn't come into widespread use as a cutting tool material until after World War II, when Kennametal founder Philip M. McKenna developed the first indexable carbide cutting tools. Since then, this extremely hard and wear-resistant material has consumed an enormous swath of the cutting tool market, drill bits included.


The influence of process parameters on thrust force during the drilling of pure and chemically treated Kevlar reinforced epoxy composites has been investigated. Surface treatment has been carried out to enhance the physical bonding between fiber and matrix. Four different drill bits were used for the investigation: standard twist, core, step cone and candle stick drill. Three speed and feed rates were used for the investigation. Our objective was to find the minimum thrust force during the drilling of pure and chemically treated Kevlar reinforced composite using four different drill bits. Optimization of drilling process parameters was performed using the Taguchi method of L9 Orthogonal Array. We found that among the four drills core and candle stick drills produce a minimum thrust force compared with the twist and step cone drills. Thrust force values produced by a chemically treated specimen is lower than that of a pure composite specimen irrespective of the drill bits used. Chemically treated specimens of the core and candle stick varieties are suitable for lower thrust force and delamination free holes under specified experimental conditions. The significance of feed rate is more important for thrust force during the drilling of composite specimens irrespective of drills.


Have you ever had a good look at your screwdriver (or any of your other handheld tools) and wondered what types of technology have been used on them? Strong, thin layers can harden the surface of your metal tools, protecting them against wear and tear and increasing their lifetimes. Even the drill bits you use in your power tools are coated for better performance. 041b061a72
