Magnetic Drills for Tapping

CS Unitec offers a line of electric and hydraulic magnetic drills that can tap holes up to 1-5/8" diameter in steel, stainless steel, aluminum, and other metals. Our accurate and portable tapping drills can thread blind holes and thru-holes on the job site or in the shop.

Using a powered tapping drill rather than hand-tapping holes reduces the risk of tool breakage and produces more accurate holes with cleaner threads.

To achieve perfect, straight threads when using a magnetic tapping drill:

  • Use coolant
  • Apply a light feed pressure
  • Choose the drill's lowest gear (if the drill you are using for tapping has more than one gear option available)
