Drill size:
-
diameter D: 1.70 mm
-
total length L: 40 mm
-
spiral length F: 15 mm
-
sharpening angle: 135 °
Twist drill from high-speed tool steel HSS-Co M35 according to DIN 338 (domestic steel marking - P6M5K5).
Complies with GOST 10902-77.
High cobalt contentCoin the alloy (about 5%) significantly increases the productivity and durability of the drill even when compared to a titanium coated surface. Alloying with cobalt also increases the red hardness (the ability to withstand overheating without degrading properties).
Without additional hardening coating.
Right-hand cutting, sharpening 135 °, i.e. for hard materials.
Sanded.
Two cutting edges, two spirals.
The shank diameter corresponds to the drilling diameter.
The 135°angle sharpener defines the recommended application for drilling the following materials:
-
alloyed and unalloyed steel
-
non-ferrous metals
-
cast iron of different grades

cermets
-
hard plastic, including fiberglass

Attention!
Drilling of stainless steel must be done at the required drilling speeds, it is imperative to use coolant (cutting fluid). The use of coolant on any metal multiplies the service life of the drill.
