Bordo Metric Red Band HSS-Co TiAlN Coated Twist Drills for Tough Treatable Steel.
DIN338
130° 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 Metric Blue Band HSS-Co TiAlN Coated Stub Drills for Stainless Steel.
DIN1897
Multi-faceted point with two helical flutes with 35 degrees of helix angle.
The machining of stainless steels is difficult due to its work hardening properties, toughness and poor thermal conductivity, which places high demands on the cutting tools.
They are designed primarily for machining operations in lathes (screw machines) but can also be used in manual hand held drills.
The Blue Band – Stainless Steel – Series has been specifically designed to suit these difficult machining requirements.
TiAlN coating increases tool surface hardness to 87Rc.
For machining materials with Hardness < 350 HB : Tensile Strength <1250 N/mm2.
