BOSCH Twist Speed 4.2mm Drill Bit for Metal

The Bosch HSS PointTeQ spiral drill bit is for drilling into alloyed and non-alloyed steel, non-ferrous metals, cast iron, and plastics. Its self-centring PointTeQ tip prevents it from slipping on the material and makes it easy to start drilling holes accurately. The high-speed steel (HSS) body of the drill bit has high elasticity, which reduces the risk of breakage. A black-oxide-coated flute ensures rapid chip removal. The drill bit is suitable for use in both portable and bench drills.

PointTeQ tip for fast and precise drilling

The drill bit is fitted with a PointTeQ tip, which, due to its geometry and 135-degree angle, does not require a centre punch. Its self-centring capability prevents wandering when starting to drill, contributing to greater accuracy. The sharp tip also helps you work faster. You can use the spiral drill bit for precise holes without needing to perform complex surface preparation.

High elasticity and efficient chip removal

The body of the drill bit is made of high-speed steel (HSS), which gives it high elasticity. This means there is a low risk of breakage. The N-type spiral flute has a black oxide coating. This coating aids in the smooth and rapid removal of chips from the drilled hole and reduces the risk of clogging. The drill bit is manufactured to the DIN 338 standard.
