About this item:
- 6.8mm 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.
