The DURA bit – for an extremely long tool life and a secure fit in the screw; ideal for working with delicate surfaces
Hard and wear-resistant, tungsten-carbide micro-particles in the bit tip gain a secure grip of the screw head, thus reducing the slipping of the bit from the screw and not only preventing damage to the surface but also ensuring optimum force transfer
Corrosion resistance over a particularly long length of time thanks to nickel coating
The ZOT bit – for craftspeople, fitters…; ideal for screw applications in metal and hard materials
Patented, tough-but-flexible, optimised torsion zone (ZOT) cushions the torque peaks after turning the screw and prevents premature breakage of the bit
The greater elasticity of the bit is used to optimise performance and wear
The HOT bit for carpenters, model-makers and kitchen fitters; particularly suited to wood and soft materials
The extra hard (63 HRC) optimised torsion zone (HOT) ensures that the optimum amount of force is applied when turning the screw, without the bit being subject to wear
Colour coating of the entire bit indicates HOT quality and also serves as corrosion protection
The Inkra bit – the specialist for craftspeople, carpenters and fitters; ideal for screw applications at corners and edges
With the Inkra bit, the penetration in the screw head and the force transfer remain almost constant even in inclined positions; the Inkra bit is thus used in applications where there is little space for power tools/hand-held screwdrivers (e.g. table edges and corners of windows)
Long tool life and protection against premature wear and pressure forces thanks to unique INKRA geometry
The bits of non-rusting stainless steel score top marks with a convincing line-up
And the XSelector Stainless can hardly be beaten, Both in terms of its 11-piece assortment (25 mm stainless steel bits) and the compactness of its box design
