New from Grąžtai: hex-shank drills
Cordless drivers are becoming ever more popular worldwide. Thanks to modern technology they can fully replace corded drills, which are less convenient because of their size, weight, cable and the need for a power socket.
A hex-shank drill can be changed in seconds, which is especially convenient in hard-to-reach places – for example on a ladder, when you need to switch quickly between bits for different operations.
A hexagonal shank also saves time compared with a round shank: it does not slip in the chuck when the drill jams in the material, so it does not leave marks on the shank or damage the chuck.
Hex-shank drills up to Ø 5 mm are pressed into the shank on a special machine; drills above Ø 5 mm are milled from a single piece of steel. This keeps the risk of breakage to a minimum.
All our hex-shank drills come with a split point. The drill centres itself, so there is no need for a centre punch, which saves time on everyday jobs. The AB Grąžtai split point is one of the most precise in the world and clearly outperforms the competition.
The new drills are made of high-speed steel with 5% cobalt, which makes them harder and more durable, especially in harder materials such as stainless steel, alloy steel and cast iron.
All hex-shank drills have a bright gold titanium nitride (TiN) coating. It greatly reduces wear because it lowers friction between the drill and the hole wall during intensive drilling.
AB Grąžtai has been making cutting tools since 1957. This experience allowed us to design a new type of drill that stands out for its drilling performance, durability and quick-change fixing – making work easier and faster.
