【High Efficiency】Our magnetic drill is suitable for drilling on any metal surface and Rack and pinion gear system for exact drilling depth.Bit size is etched on each cutter.The pilot pin helps locate the center of the hole location.
【Annular Cutter】SDT annular cutters will drill large holes up to ten times faster than regular drill bits.Machine-finish hole with no reaming needed when using a lubricant.Make overlapping holes, slotting holes, and edge cuts.
【Advantages】During the drilling process, the pilot pin will retract into the cutter allowing lubrication to reduce heat gain in the slug.e pilot pin helps eject the slug after drilling is complete.
【Wide Applications】Applicable to steel structure, shipbuilding, equipment manufacturing, equipment installation, bridge engineering, wind power, drilling rig, power construction, railway manufacturing, etc.
