COUNTERSINK DRILL BIT USE
A countersink drill bit is a type of tool that attaches to a drill press or portable drill. It is used to create a depression into the material, allowing screws to be hidden from the surface.
This is possible when the countersink produces a conical hole that matches the shape of the screw. And as soon as the screw is inserted, it perfectly fits into the hole and is automatically flushed or sits slightly below the surface.
This type of bit is usually used when drilling into hardboard products such as PG Bison SupsWood and hardwoods. But in some cases, a countersink drill bit may also be used for creating screw holes in steel, tool steel, stainless steel, cast iron, brass, and aluminum.
Additionally, countersinking a hole also reduces burrs or sharp edges on the material, especially if you are dealing with metal. This means less deburring work for you.
DRILL BIT TYPES
There are several countersinking styles used by experts and each of them serves a different purpose. Flute-less countersinks, for example, are ideal for deburring projects. On the other hand, single and multiple flute countersinks are used to create space for a countersunk fastener.
This variety in the purpose of countersink bits also explains why the product is offered in various sizes. They are available in different measurements—16.5mm, 20.5mm, 25mm, 35mm, and 40mm. Depending on the size of the drill bit used, angles in different sizes are made for the fixing to fill.
Once the fixing is placed into the countersink hole, it can either be filled or sanded so the surface looks completely flat. This is a great way to repair objects and still be able to make them look like nothing happened.
If you find yourself needing to fix something that requires flawless results—whether it be made of wood, concrete, or metal—consider getting drill bits that are specially made for countersinking and you can easily achieve your goal for the project.
