The Solid carbide spot weld drill bit is a spiral drill for boring weld points on the vehicle body. Also suitable for drilling in high-strength steel sheet and extremely hard sheet metal, eg in vehicles. Also suitable for hard car body steels in the crossbeams, etc. The solid carbide welding point drill is also used in car body construction, where HSS drills have to be replaced quickly because of the short service life.

The Solid carbide spot weld drill bit has a newly developed geometry of the drill bit. It is designed for cutting, but still shows a long service life. The drill cutting edges are provided with a slight chamfer at the outer edges. This chamfer provides a clean drill hole with high cutting edge stability.

The innovative high-hard special coating made of TiAlN extends the service life. This is clearly evident when drilling in high-strength steel.

The drill shaft is provided with a length of approximately 20 mm with three symmetrically arranged clamping surfaces. These give a firm hold in the 3 baking food. This prevents the turning of the weld point drill in the 3 jaw chuck.

Instructions for drilling with the Solid carbide spot weld drill bit

• Solid carbide is a material with extremely high hardness. In this way, however, it is also very brittle and breaks easily when handled improperly.
• Make sure that the Solid carbide spot-weld drill bit is drilled exactly and in any case at right angles. Then drill it with even pressure.
• Interrupted cuts must be avoided.
• It is absolutely necessary to avoid hard positioning, lateral impact as well as dropping the welding point drill. This leads to breakouts on the drill bit.
• At some point, the best tool is blunt. If this is the case, you can have the Solid carbide spot-weld drill bit sharpened here at pwwu24.de Onlineshop. This is not only the case for Solid carbide spot-weld drill bits that you buy from us, but also for the drills of all other manufacturers.
