Characteristics
Assembly
Detachable head type drill using a radial
serrated connection design for high precision and strength.
The exchangeable drill head provides a
new cutting edge, higher productivity and
cost efficiency with easy tool management.
Regrinding allowance of 1,5mm to 3,0mm
makes further tool cost reductions possible.
Front screw clamp design
MultiDrill design +
special coated carbide
Radial serration provides steady and
precise clamping
Oil holes are directed at cutting lip

Characteristics of DEX Coating
Sumitomo Electric Hardmetal‘s next-generation drill coating utilises nano-coating technology to provide
more than double the tool life of conventional coatings.
Silicon and chrome improve wear, heat and adhesion resistance.
New super multi-layered structure offers significantly improved chip resistance (coating strength).

DEX Coating
Overlap Thinning
Large thinning angle
Cutting edges perform superbly with SUS and soft steel
Large thinning angle solves the convex R part breakages peculiar to
soft steel and reduces adhesion breakages with SUS.
Improves chipping resistance around hole openings in Cast Iron
Small edge treatment
Sharp peripheral cutting edge
Edge sharpness improvements in peripheral areas prevent chipping
around hole openings in cast iron.
