Factors To Consider When Buying Core Drill Bits

Professionals know that their tools are their livelihood. The wrong tool can mess up a job badly, causing delays and dissatisfaction. This is especially true of jobs that involve cutting, grinding, or drilling hard materials like concrete, stone, or even asphalt. That&#;s why every pro (and even skilled DIYers) should know these factors to consider when buying core drill bits.

Size

Diamond drill bits come in sizes as small as 1mm in diameter and as large as 60mm or larger. The materials you&#;re drilling coupled with the size hole you must make will dictate the drill bit you need to do the job. Refer to the manufacturer&#;s recommendations to match the size to the materials and the job.

Bond

Just as with diamond saw blades, the bond that adheres the diamonds to the drill bit is important. When you&#;re drilling softer materials, you need a harder bond that won&#;t wear away too fast. With hard materials, you need a softer bond that will expose a fresh layer of diamonds as the drill does its work.

Diamond drill bits come in electroplated and sintered bond versions. Electroplated drill bits have one layer of diamonds, suitable for drilling softer materials. Sintered bonds create layers of diamonds that are exposed when the surface above wears through. These are suitable for drilling harder materials like concrete and stone.

Grit and Density

Grit refers to the size of the diamond particles bonded to the surface of the drill bit, while density measures how many diamonds occupy a square inch on the surface of the drill bit. Hard materials need coarser grit measures, while softer materials need a finer grit, much like sandpaper measured in coarse to fine types.

Depth

How deep must you drill to complete your job? Diamond drill bits are available in different lengths capable of penetrating materials from tenths of millimeters to over a foot in inches.

Penetration Rate

Diamond core drills will bore through materials at different rates. Check the manufacturer&#;s specifications to match the materials you intend to drill with the penetration rate the drill bit can achieve. Of course, much depends on the power of the drill you&#;re using, but if you apply too much power or pressure to some drill bits, they won&#;t perform as well. The geometric pattern of the drill bit&#;s tip will also affect penetration rate.

How Durable are Diamond Core Bits?

There are two main ways that the diamonds are bonded to the drill tip. This answers the question, &#;how durable are diamond core bits?&#; These include bonded and sintered. With bonded tips, the diamonds are bonded to the tip through a process that is similar to electroplating. These are less durable and can wear out through use. The benefit is that they are less expensive. On the other hand, with a sintered tip, the diamonds are embedded into the tip. This layering of embedded diamonds means that they are particularly useful for working with very hard materials and have a longer lifespan. This makes them more expensive.

To keep a tip in good condition, they need to be lubricated with water or synthetic mineral oil to reduce the heat build up during use. This extends the lifespan of the diamond core bits. There are two ways to introduce the lubricant: the hose method and the spray bottle. The hose method is using a hose that allows water to continually run down the bit. The other method, spray bottle, is also pretty straightforward. It requires someone to spray water while the other person performs the drilling function. In most cases, this is the less effective method, though it does work. The most important thing, regardless of the type of lubrication method you choose, is that the drill tip is continually lubricated. This keeps both the drill tip and the material you are working on from overheating.

The answer is &#;it depends&#;. There are several factors that can impact the longevity of the diamond core diamond core bits: material being drilled, speed of drilling and lubrication. First, if the diamond core bits is being used on very hard materials, eventually the abrasive quality of the material will wear on the bit. Next, the speed and pressure used to drill hard materials will eventually affect the viability of the bit. Experts recommend drilling at slow speeds to help the bit last longer. Lastly, ensuring that the diamond core bits is properly lubricated will prevent it from overheating. This also goes back to using the right diamond core bits for the material that you are working with. With the right diamond core bits, proper lubrication at the right speed, the diamond diamond core bits will last longer.

Another consideration that affects the lifespan of a diamond core bits is pressure. The pressure can be increased when working with more pliable materials. During operation, speed can be increased while experiencing less heat buildup. The inverse is true as the material is harder. Pressure and speed must be reduced, and lubrication must be increased. This helps to avoid overheating which reduces the longevity of the diamond core bits.

There are several factors to consider when using a diamond core diamond core bits. Each one can affect how long that diamond diamond core bits will last. It also affects which type of diamond diamond core bits should be used for the work that you are undertaking. Several signs to watch for include any black, yellow or brown burn marks around the diamond drill tip. This signals that there is overheating, inaccurate speed and excess pressure. If you watch all of these important factors and consider the work that you&#; re doing, the diamond core diamond core bits will last longer. Also, watching for any signs that there are problems or overheating can prevent issues with the diamond core bits and the work that you are doing. Keep these things in mind and your diamond diamond core bits will have a long lifespan.
