Solid carbide deep-hole drills

KN25™ Grade (B27_HPS)
• Sharp cutting edge enables higher tool life
in aluminium and other non-ferrous materials.
• The uncoated grade helps to prevent built-up
edge in drilling aluminium and high-temp alloys.

New KCMS20 Grade (B27_SGL)
• Monolayer PVD AlTiN coated ultra-fi ne grain carbide with
superior surface finish.
• First choice for deep hole drilling of stainless steel and
high-temperature resistant materials. Due to the coatings
enhanced high temperature properties, this grade can also
be applied for MQL applications in steel.
