Quattro cutting edges, unequal pitch

Countersinking reimagined. The unequal pitch of the Quattro countersink elevates universal, precise and fast countersinking to a new level. Whether using a cordless driver, box column drill or machining centre, the extremely smooth running and perfect countersinking pattern are impressive across the board. The Quattro countersink geometry, proven HSSX base material and oxide surface treatment make this tool unique.

Field of Application:

Universal use in steel (up to 1,100 N/mm²), stainless steel, up to Hardox 450, cast materials, plastics, non-ferrous base metals and light metals.

Advantages:

Quattro countersink geometry
- Unequal pitch of the Quattro cutting edges - extremely smooth running and therefore a perfect countersinking pattern without chatter marks
- More cutting edges in use - significantly faster and more precise countersinking results
- Distribution of the acting forces over more cutting edges - gentle on materials and conserves energy
- Lower feed forces required - easy working

Latest generation - HSSX base material
- Maximum heat strengthening for a longer service life
- Universal - can also be used in stainless steel and Hardox 450

Surface
- The multifunctional steam oxide (Fe2 O4) surface is an adhesive oxide coating with a thickness of 0.010 mm and offers the following advantages:
- Improved adhesion of cooling lubricant on the tool surface prevents built-up edges and cold welds.
- Improves chip removal from the cutting edge - reduces heat development in the critical zone.
- Increased surface hardness - therefore improved wear resistance.

TRICON shank
- Prevents spinning in the drill chuck - therefore no damage to the countersink
- Mechanical interlock in the drill chuck - securely and firmly clamped, particularly in the quick-action drill chuck
- Optimal power transmission
