Hole machining
Deep-hole Drilling Product Introduction
Achteck has general-purpose deep-hole drilling inserts, which offer high productivity for many industries: energy, engineering machinery, injection molding, aircraft, shipbuilding, military, etc. It can achieve good hole straightness in deep hole drilling and good surface finish. Existing geometries and grades cover steel, stainless steel and heat resistant alloy drilling.
Product application and features ● The inserts can be mounted on the deep-hole drilling head. ● AP301U(N) is the first choice for drilling steel and stainless steel ● All geometries offer good chip-breaking result ● Increased efficiency due to high feed rate ● Reduces the cost per hole
