This is a Busch carbide twist drill.

FIG 4205S CARB TWIST DRILL

Due to its short working part, the twist drill 4205S is an easy guiding tool to produce precise, uniform holes in very narrow spaces as necessary for tight pavé settings. When working on jewellery materials which are difficult to cut, such as platinum, titanium and steel or gold, silver and their alloys, numerous holes can be drilled with constant precision after centering, using this tool made of finest grain carbide.

Recommended speed: 3,000 - 5,000 rpm
