Drilling a hole in a pane of glass or a mirror is simple. The key is to use a carbide bit made especially for glass, sea glass, wine bottles, glass block, tile, stone, granite and marble. You’ll find these bits at most home centers alongside other drill bits or ceramic tile tools.
Bench grinders are so incredibly cheap that every home workshop should have one. As we covered in using bench grinders, there’s a host of uses for a bench grinder, including grinding welds and shaping metal. But perhaps the greatest real-world use is sharpening drill bits.
Our re-sharpening tool machines not only provide drill bit repair, drill bit sharpening, drill bit tipping, and chisel sharpening of our own carbide tipped drill bits, but those made by other manufacturers as well at a fraction of the cost of new ones! So don’t throw away those expensive carbide tipped drill bits, use PURROS drill bit sharpening machines to repair them.
Good quality drill bits are expensive – very expensive in large sizes. But once you can competently sharpen drill bits with a bench grinder, you can buy lots of your drills secondhand, massively dropping the purchase prices.
PURROS provides the drill bit grinding machines that can repair various materials and types of drills. Reconditioning maintains the exact geometry and coating of the original tool. Tool reconditioning is a reasonably priced alternative to buying new tools while still maintaining the same performance. To this end, by the time a tool is reconditioned for the third time, tools costs are reduced by 50 percent.
Drill bits can be sharpened in several ways, and it might be handy to learn if you personally do the installation of your home’s hardwired security system. Even if you don’t hit any nails while drilling holes for your home alarm and other security devices, your bits will still get dull.
Drill Bits are very expensive, especially the long ones used for the wiring of home security system. Rather than replacing them, you should sharpen the bits to save you money and also make drilling easier and faster, since you will have in your possession freshly sharpened bits.
A drill bit grinder is available for purchase and it brings a dull bit back to its original form. It is advisable not to purchase a special tool that only has one function. Especially when an almost good drill bit grinding machines is already sitting on your workbench.
Using a drill bit grinder attachment on a bench, which can be found in various home workshops, you can easily sharpen your bits. They might not be as perfect as the original bit, but they will get you back in action as fast as possible and crazily drill holes

Step 1: Checking the point angle (cutting lip angle) of standard twist drill bit is correct or not, and whether it is symmetric with the axis of the standard twist drill bit? (The correct point angle of standard twist drill bit is ±118°, if it be used to drill harder materials that the point angle can be extended to 120°; if there are the softer materials, the point angle should smaller than before, but keep mind, do not smaller than 90°.)
Step 2: To check the length and height of two major cutting lip (major cutting edge) are consistent. Because the quality of the machined holes are affected by whether the length is the same.
The check method for step 1 and step 2 is that: Place the cutting part of twist drill bit keeps in a vertical position, keep eyesight at the horizontal level, and then repeatedly rotate 180°, where is the center axis of standard twist drill bit, to observe whether the length of two major cutting lips are same in rotation. It is an assumption that to observe the length of two major cutting lips at the center of axis; If the lengths of two major cutting lips are different, that the shorter side should be grinded.Continue reading
