Description

The HSS step drill bit for step-by-step reaming and deburring of metal and plastic is valued for its high heat resistance and long service life. With the ground centring tip, you can pilot drill the workpiece at the exact point needed. The 90° countersinking angle means that you can easily transition from step to step until you reach the desired diameter, while deburring the edges of the cut simultaneously. The special 3-edge cutting geometry ensures very quiet running and fast work progress. Chips that form are optimally transported away via the straight chip grooves. The step drill bit is available in different sizes and with different steps. Thanks to the ¼" hexagon shank, it is quickly ready for use. The step drill is produced in Germany – that means you are investing in a high-quality, durable product.
