Description

Scope of Delivery:

- 3x Bosch HSS-AlTiN step drill ( 4 - 12 / 4 - 20 / 6 - 30 mm )

Product Description:

The Bosch HSS-AlTiN stepped drill bit enables quick and easy drilling of holes with different diameters. The cross-ground drill point makes it easier to start drilling, so no centre punching is required. The CNC-milled spiral flute optimally removes swarf and ensures low-vibration and therefore even drilling. The axial and radial relief grinding ensures maximum cutting performance and absolutely smooth results. The HSS steel is coated with AlTiN (aluminium titanium nitride), which guarantees a service life optimised for the use of coolant. The laser-marked diameter markings in both spiral flutes are permanent and easily recognisable. The 3-face shank enables a high torque and therefore fast and precise work. The Bosch HSS-AlTiN stepped drill bit is the perfect companion for anyone who wants to drill holes quickly and reliably. With its excellent performance and durable coating, it always offers optimum results.

    Buying direct is cheaper for you – find out why

    Price comparison portals and search engines charge high fees on every purchase – often over 20% of the selling price. These costs are always passed on to customers. We do things differently: instead of spending advertising budgets on large platforms, we invest in fair prices, BROpoints, gifts and exclusive best-price deals you'll only find directly with us. No middlemen. No markups. Direct for you.
