Bordo Jobber Drill Set HSS Cobalt 1/16 - 3/8", 21pieces

Product Features

• Bordo Fractional Cobalt Tough HSS-Co5 Twist Drills.
• 135° 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 135° 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.
