Selecting The Right Power Drill For Your Drilling Operations

By: Mark Bruddy

Astonishing advancements have been made in the drilling industry during the past few years allowing drillers to exercise complete control in reaching a specified targeted zone. However, the goal of the drillers rest in achieving a high rate of penetration (ROPs) as higher the rate of penetration the lesser will be their efforts and overall drilling costs. To achieve higher ROPs, every aspect of the drilling operations should be carefully examined and refined. One of these technologies involves the careful selection of the perfect drill for various drill operations. Selecting the right Diamond Drills/Bits for your application is a key to obtaining desired diamond drilling results.

Materials to be Drilled
Materials you are planning to drill have a great impact on the type of diamond drills you are going to use. If you are drilling an ultra hard material such as alumina, and other type of advanced ceramics, precious and natural stone, and high metallic content materials, you must use a metal bonded diamond drill. However, if you are drilling a less expensive and softer material such as tile, glass, composites- diamond drill may be the best and cost-effective solution. You will be amazed to know that harder materials require softer bond to drill faster whereas softer materials require a harder bond to last longer.

Material Cost before Drilling
Material cost plays a crucial role in selecting the right diamond drill or diamond bit for your application. If the material you are planning to drill is precious or expensive, it is suggested to obtain a thin wall diamond core drill minimizing the material loss and deformation. It is always a good idea to keep an estimate of targeted cost and quality per hole to mitigate the risk.

Material Thickness
The thicker the material you are going to drill, the greater the amount of the pressure and coolant is required. It is suggested to run coolants from multiple directions. This will ensure maximum amount of coolant and lubrication reaching your drilling zone. Sometimes special features are unnecessarily specified simply to convince customers of drill technical ability. Most important is correct coolant type and pressure along with suitable speed and feed.

Speed and Feed
Before selecting the right power drilling operations, you must consider the speed of the drill. Speed and feed are dependent on pressure, material type, coolant type, hole depth, condition of the drill and its style. Speed and feeds are the conservative starting point and will be affected by all operating conditions.

There is a perfect drill for every buyer in the market. The catch is how to find it. Today's contractors, manufacturers and hobbyists involved in diamond drilling operations encounter wide variety of applications and challenges. The mounting speed of the ever increasing and advanced materials transform the way we look at the diamond drilling. New material requires niche technology and methods. An expensive hit-and trial method can be averted with proper and detailed understanding of your materials and objectives of performing drilling jobs. With proper preparation, and following basic drilling technique you can successfully select the right power drill to make a difference in the success of your drilling operations.
