This high quality trade rated bit set is supplied in a robust steel storage case; the kit comprises a universal shank magnetic bit holder (compatible with all makes of tools including Festool's Centrotec) and an assortment of 27 colour coded bits held in place by an industrial foam storage holder to stop them rolling around. As well as keeping the bits secure, the steel case also makes them easily accessible and because it's so robust it can be used again and again once the bits need replacing.
The slotted (green) and Philips (Blue) bits are coated with Titanium Nitride (TiN) which is known for it's wear resistant properties, this helps the bits retain their edge and increases their lifetime while also protecting against corrosion.
Each bit has been made from S2 grade steel which is a harder steel and is naturally more resistant to wear. The Pozi bits are also sand blasted which gives them better grip. Critically the geometry in each tip is designed to form an exact fit with the screw head, this prevents them getting stripped and ultimately gives you better accuracy.
