This means a higher cutting performance, low pressure and vibration- free working as well as low wear! Three flutes DRILLS, HOLE SAWS, DIAMOND TOOLS Each step has a radial and axial back taper, whereby the blade represents the highest point in diameter and in the cutting step – ensuring the utmost in cutting performance and complete smoothness! Back taper The drill bit shaft has three clamping surfaces. This ensures a solid hold in the chuck and prevents slipping in the machine, even when dealing with severe loads. Three drive surfaces Each hole diameter can be accurately read in the flutes. Laser-inscribed drilling steps drilling through the transition and into the next drill bit step in the same work stage prevents sharp edges. Automatic deburring The double-edged drill bit shape guarantees accurate centring and drilling, even when dealing with thin-walled material – no punch- marking or pre-drilling required and it is not possible to slide away. Special centring point design On a step drill, the tapping device is the part that is under the most stress. Therefore, CIMCO step drills have exchangable centring drill. Once the centring drill become worn, it is only these drill that are replaced within in a matter of seconds and not the entire drill bit– which saves a lot of money.
