The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the tangible being drilled, it is assertable to accomplish better tool life, hole geometry, precision, and productivity. During the nineteen-twenties and thirties, rivets and bolts were still a primary way of joining metals.

P&Q University Lesson 4- Drilling & Blasting | Pit & Quarry
The initial production steps in a prey operation – boring and blasting – can importantly issue the productiveness and outlay of most downstream operations, including loading, hauling, crushing and screening, and product yield – the relative volume of high-value crushed gem products versus low-value byproducts. Properly designed and carefully executed, drilling and blasting content the first, and maybe greatest, opportunity to optimize quarry operations and control costs. Since the sun-up of the industrial age, mechanized drilling has been one of those cardinal technologies that radically changed the cost and scale of production in a way that enabled and made viable economically the rest of the canonical industries, which in turn has given us the kind of action and lifestyle that the ancients could not conceive of.
