Metal drill bit HSS-G TiN 4 mm - Per Piece

Wovar's metal drills are made of high-strength steel. As a result, our metal drills have a high fracture resistance. The Wovar metal drills are not only completely ground and very strong, but also provided with a TiN coating. This makes the drill heat resistant up to 600 ºC, which leads to longer tool life and better cutting values.

What can I use the metal drill for?

This metal drill from Wovar is suitable for drilling holes in steel, cast steel alloyed and unalloyed (up to 1100 N/mm2 strength), grey, malleable iron, ductile and die-cast iron, sintered iron, nickel silver, graphite, short-cut aluminium alloys, brass and bronze. Do you want to drill in hardwood or softwood? Then use our hardwood drill. The difference between a metal drill and a hardwood drill is that the hardwood drill is slightly sharper, so that it slides through the wood faster.

What is the advantage of the TiN coating?

The titanium-nitride coating (TiN coating) makes this metal twist drill very strong. This is because the surface hardness is increased to approximately 2300 HV. In addition, it increases the heat resistance of the drill up to 600o  C. Metal drill bits can get very hot. This will cause them to warp or break. The TiN coating on Wovar's metal drills significantly reduces this risk.

Tips for drilling in metal

Before you start drilling, it is recommended that you punch a small point in the metal so that the drill does not slip. When drilling large holes in the above materials, it is recommended to pre-drill with a 4 mm metal drill.
