OSG 17551511 | V-SERIES 27/64" Drill Size x 0.422" Shank x 145.00mm Flute Length x 205.00mm OAL x 120 Degree Point Angle 2 Flute WXL Coated HSS-CO 1750 Extra Long Drill Bit

The V-Series HELIOS is the 1st drill to process deep holes 10X-20X diameter, without pecking and without the use of internal coolant supply. Flute form, point thining and compound lead construction are all patented technologies developed by OSG to make this drill do what no other parabolic HSS-Co drill can. The addition ofexclusive WXL coating technology makes non-peck drilling repeatable, even in the longest of production runs.

Features & Benefits:

• Pat Low-resistance web thinning: Reduces penetration force by as much as 35%
• OSG WXL Nano Coating: Higher coating oxidation temperature & hardness dramatically improve wear resistance
• Pat Flat Flute Form: Looks like parabolic, but isn't! This flute form ensures extra space while increasing chip evacuation velocity
• Pat Compound Flute Contruction: Ensure chips curl tighly and move freely through the flutes to ensure stable evacuation
