What do you use a countersink for?
You can work a borehole with a countersink drill so that a screw gets deeper into the material and does not protrude. In that way you "countersink" the screw and ensure a beautiful finish.
Countersinks can also be used for:
• Deburring holes.
• Applying a chamfer in a hole before the thread is tapped.
• Countersinking a screw head in the material.
How do you use a countersink?
Before working with the countersink, a hole must be drilled with an HSS twist drill first. The countersink drill is not suitable for drilling holes.
After drilling a hole with the HSS twist drill, put the countersink in the cordless drill. Please note: you cannot use the countersink in a screw machine with impact function. This can considerably damage the cutting edges of the countersink. With the countersink you can drill a wider hole in the material at the same place, so that you can "sink" a screw head deeper into, for example, wood or metal. Then coat the wood with putty and finish the material with paint. Then you no longer see anything of the screw.
HSS ground countersinks
HSS ground countersinks are made from high-quality high-speed steel. Completely sharpened during the production process creates a very sharp countersink with high precision. As a result, the drills in combination with cutting oil have a very long service life. The countersink deburrs and countersinks in just one operation. The cylindrical connection ensures optimum grip in the drill and prevents slipping. Very suitable for use in wood, plastic and unalloyed steels such as sheet steel, structural steel and cast iron.
