Composite Drill Bits For Circuit Boards And Everything Else



Onsrud Cutter, one of the leading providers of carbon graphite drill bits and other composite drill bits, is on the forefront of technology for composite drilling. Their composite drill bits can create clean holes in composite sheets, eliminate delamination, and even produce custom sizes and lengths.

There are many different materials and products that composite drill bits are used for, such as printed circuit boards. Fiberglass is one of the most common types of composite material, and circuit boards are made of fiberglass. Composite drill bits are necessary to produce the hundreds or thousands of holes in circuit boards

Carbon graphite drill bits and other bits that are used for composite drilling are typically used at extremely high speeds, in the range of 30,000 to 100,000 RPM or higher. Carbon graphite drill bits are also very small, and the material they work with is very brittle, so even the slight wobble of an operator's hand could shatter the composite drill bits. Because of their delicate nature, composite drill bits can't be used in a hand drill, which would also not be able to provide the precision needed for circuit boards.
