Drilling Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool , often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute .

Making headway in drilling composite materials - Composites The right combination of cutting edge geometry and tool material is the best success factor for drilling composites, and as such, often dedi ed to the material. Composite materials have a very abrasive character when machined due to the hardness of the fibres, and bonded in a weaker resin there are tendencies for fibres to be pulled out.

How To Machine Composites, Part 1 -- Understanding Composites In a composite, one material is the matrix and at least one other is the reinforcement. Carbon fiber reinforced plastic CFRP , the chief composite material in aircraft parts, consists of a plastic matrix with carbon fiber reinforcement. The shop that tries to machine this combination material faces a combination of challenges.

How To Machine Composites, Part 4 -- Drilling Composites A smaller point angle tends to produce better exit quality. However, too small of a point angle can give the tool poor edge strength. For CFRP, the optimal compromise seems to be a point angle of 90 degrees. By comparison, a more typical point angle for drilling metal is 135 degrees meaning the composites drill is “pointier” .

Safe-cracking Scoping a safe is the process of drilling a hole and inserting a borescope into the safe to get an intimate look into a specific part of the security container. When manipulation proof mechanical locks and glass re-lockers are implemented as security measures, scoping is the most practical option. One common method is called 'scoping the change key hole.' The safecracker will drill a hole .

CoroDrill 452 - Close-tolerance drilling in composite material This hand-drill assortment delivers excellent results when machining rivet and bolt holes. These drills are optimized for composite and metal-stacked materials.

Tungsten carbide Tungsten carbide chemical formula: WC is a chemical compound specifically, a carbide containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, WPC-piercing shells and jewellery.

Cutting, Drilling, Trimming and Finishing Composites Every composite part, post-mold, requires some sort of finishing, ranging from the drilling of holes to the trimming of excess material. Ironically, particularly given the universality of CNC operations in composites manufacturing, one of the very worst things you can do to a composite part is drill it or cut it.

The Good, Better and Best Ways to Drill - Elevated Materials The best bits for drilling carbon fiber are solid carbide or diamond. These bits are very brittle though and should only be used in a rigid setup like a drill press or mill. If you try to use these with a hand drill, even if you use drill bushings, they can easily shatter.

Drill Drilling capacity indicates the maximum diameter a given power drill or drill press can produce in a certain material. It is essentially a proxy for the continuous torque the machine is capable of producing. Typically a given drill will have its capacity specified for different materials, i.e., 10mm for steel, 25mm for wood, etc.

How To Machine Composites, Part 4 -- Drilling Composites Drilling tends to be the real challenge of machining composite parts. A drill cutting through a metal part simply has to remove the material and clear the hole. By contrast, a drill cutting through a layered composite structure is likely to push the layers ahead of it, producing unacceptable delamination on the exit side.
