Features & Benefits
Eccentric 4-Margin Design
- A unique coolant channel design allows repositioning of the trailing margins for improved stability over conventional two and four margin drills.
- Eccentric style clearance reduces margin contact with the workpiece without reducing strength.
End Geometry
- The primary only relief allows the trailing margins to help stabilize the drill up to three times sooner than conventional designs.
- High shear corner geometry minimizes exit bur.
- Computer controlled edge hone protects against edge chipping in difficult applications.
Coolant Channels (146U Only)
- The two-channel design provides additional coolant in the hole when thru-tool coolant is not available.
Carbide & Coating
- Proprietary SGS Ti-Namite-X coating and post-coat polishing combine to minimize material adhesion and maximize wear resistance in a wide range of workpiece materials.
- All Series 136U and 146U drills are manufactured from lab certified premium quality carbide.
