FLAT BOTTOM
HOLEMAKING
Hi-PerCarb® | Series 146U / 136U
The SGS Hi-PerCarb® Series 146U and 136U flat bottom drills provide a robust solution to a variety of challenging holemaking applications in the automotive, agriculture, oil and gas, and general machining industries. Whether drilling conventionally, on angled or curved surfaces, cross or intersecting holes, unique features of the SGS design combine to produce precise, high-quality holes, with minimal breakout bur.
Features
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 faster than conventional designs
- High shear corner geometry minimizes exit bur
- Computer controlled edge hone protects against edge chipping in difficult applications
COOLANT CHANNELS
- The two-channel design provides additional coolant in the hole when thru-tool coolant is not available
Coating
Combine to minimize material adhesion and maximize wear resistance in a wide range of workpiece materials.
