Solid drill bit 0694453 series

multi-purposeHSSstep

The latest generation of Performance stepped drill bits for longer service lives, significantly faster drilling with smooth running and greatly reduced formation of burrs when processing thin workpieces made from conventional steel with a strength of up to 900 N/mm2, aluminium, cast iron, brass, bronze, wood and plastics. Type description: HSS (plain) Surface: Plain Description 4 times longer service life Compared to comparable bare stepped drill bits Improved centring and up to 100% faster spot drilling Exclusive Speed grinding Acceleration of the overall drilling process Significantly lower feed forces Optimised cutting geometry Completely smooth running without getting caught in the workpiece No distortion of sheet metal Improved roundness of the hole Greatly reduced formation of burrs on the edges Up to 80% reduction in force exerted on the tool during the drilling process Optimised cutting profile with smoother transitions between the individual stages 3-face shank No twisting in the drill chuck: faster, more comfortable working Optimum transmission of forces Protection of the drill chuck from damage Little effort required to open and close the drill chuck Notice For the stepped drill bits/material assignments, see the overview tables
