Bordo No. 1 Square Screw Extractor | AIMS Industrial

Bordo MTS Adaptor for Annular Cutter

• Chrome Molybdenum square screw extractor.
• Square screw extractors feature four sided sharp undercut edges to provide a solid grip and will not expand damaged fastener during extraction.
• They are ideally suited for removing broken bolts, studs & socket screws from medium to hard metals.
• Typically the required screw extractor will be approx. 2/3 the diameter of the fixing you are extracting.
• Use a centre punch to mark the centre of the fixing before drilling to prevent the drill bit wandering.
• Select a drill bit that is suitable for drilling into the specific material - typically HSS or HSS-Co5.
• Ideally the drill should be "Left Hand" which will prevent further tightening of the fixing during drilling.
• When using left hand drills ENSURE THE DRILL IS SET TO REVERSE.
• Drill pilot hole in centre of broken bolt, screw or stud.
• Lightly tap screw extractor into hole and turn anti-clockwise with a tap wrench or spanner.
• Damaged bolt, screw or stud will unwind out of the hole.
• Avoid excessive lateral loads - breakage could result.
• Wear eye and hearing protection.
