SUTTON Jobber Drill Sets – Heavy Duty Cobalt
Sutton Tools Heavy Duty Cobalt jobber drills are industrial quality for drilling materials that have high hardness and tensile strength such as cast iron, bronze, hard steel & stainless steel. These drill bits feature a thick core for increased rigidity in hard materials.

- 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.

- DIN338
- 135º Split Point (crankshaft point).
- Split point is self centering and the short distance from the drill axis to the outer corners results in faster penetration, reducing the need for end thrust.
- The 135º point should be used to cut harder steel materials especially in deep hole applications.
- In these situations it will produce thicker chips minimising work hardening of the cavity.
- Faster penetration reduces abrasion and friction along the cutting edges.
- Cobalt HSS Twist drills are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
- Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.
