Designed to be used in magnetic drilling with HSS Weldon Shank cutters above 11mm.
Designed to be used in magnetic drilling with HSS Weldon Shank cutters above 11mm. They are available in 25mm to fit HSS Cutters of the same length.
For best results use a centre punch to create a small impression in your workpiece. The pin should be placed in this indentation surrounded by the drill bit ready for cutting. The pin is spring-loaded so that once the cut has been completed the waste piece inside the cutter is ejected. During drilling, the pilot pin retracts and allows internal coolant to reach the cutting teeth bits.
It is strongly recommended to use a cutting and tapping spray on the dill bit.
This will not only increase the lifespan of your cutters but will ensure an increased cutting speed.
