7.8mm HSS Cobalt TiAlN Coated Blue Band Twist
Bordo Metric Blue Band HSS-Co TiAlN Coated Twist Drills for Stainless Steel.
DIN338
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.
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.
