BORDO Screw Extractor 10 Piece Set Nos 1-5 & Left Hand Stub Drills
- Screw Extractor 10 Piece Set Nos 1-5 & Left Hand Stub Drills
- 10 Piece Set, includes HSS-Co5 (Cobalt) Left Hand Stub Drills.
- Chrome alloy spiral screw extractor.
- Coarse-pitched tapered screw thread.
- Spiral flute screw extractors 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.
