Description

• DIN338
• 118° Split Point (crankshaft point).
• Split point is self centering and reduces the need for end thrust. Friction at workpiece is reduced.
• 118° point angles are ideal for use in materials such as mild steel and cast iron.
• The 118° point creates easily controlled chips which are wide and thin.
• Bright Finish Twist Drills have no surface treatment and are supplied in the as-ground condition.
• These tools are suitable for general purpose use, particularly for non-ferrous applications.
