BORDO Red Band HSS-Co TiAlN Tough Treatable Steel Drilling

Bordo Metric Red Band HSS-Co TiAlN Coated Twist Drills for Tough Treatable Steel.
DIN338
130Â° UX point with two helical parabolic flutes with 33 degrees of helix angle.
The mechanical properties of materials are influenced diversely by the addition of alloying elements and heat treatment processes, resulting in some high-strength, quenched and tempered steels or hardened steels.
This range has its own unique set of machining requirements which are satisfied by the Red Band – Tough Treatable Steel – Series.
TiAlN coating increases tool surface hardness to 87Rc.
For machining materials with Hardness < 470 HB : Tensile Strength <1500 N/mm2.

BORDO Bright HSS Jobber Drill Set

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.

Delta Point drills have a multi-faceted cutting tip.
Rather than try and modify existing point types, or tweak the grind angles, Delta Point tip design required a revolutionary re-think of drill tip function.
The overall length of the cutting edge significantly exceeds that of conventional drills.
This means more edge doing the cutting and the results are simply extraordinary.
Drilling times for a range of split point and Delta Point drills consistently showed that Delta Point bits were twice as fast in mild steel.
During independent lifetime testing Delta point drill bits averaged 609 holes in 20mm mild steel, ten times more holes than split point drills.
DRILLS FASTER LASTS LONGER.
