2.5mm HSS Cobalt TiAlN Coated Blue Band Stub Drill

About this item:

• 2.5mm HSS Cobalt TiAlN Coated Blue Band Stub Drill
• 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.
