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 of our exclusive WXL coating technology makes non-peck drilling repeatable, even in the longest of production runs.
- 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.
Application: Cast Aluminum, Aluminum Alloy, Cast Iron, Carbon Steel, Alloy Steel, Die Steel, Staineless Steel, Hardened Steel < 45 HrCAny deep hole application where coolant-through is not an option, but cycle time and tool life are important.
