Twist drill from high-speed tool steel HSS-Co M42 according to DIN 338 (domestic steel marking - P2M10K8-MP).
Also, this steel has a commercial name "Super Cobalt"
Complies with GOST 10902-77.
High cobalt contentCoin alloy (about 8%) and molybdenumMo(about 9%) significantly increases the productivity and durability of the drill even when compared to a titanium coated surface. Alloying with cobalt and molybdenum also increases the red hardness (the ability to withstand overheating without degrading properties).
Recommended for machining high-strength stainless and heat-resistant steels and alloys in conditions of increased heating of the cutting edge.
High abrasion resistance.
Without additional hardening coating.
Right-hand cutting, sharpening 135 °, i.e. for hard and soft 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
Characteristics:
drill type: twist
direction of rotation: right-handed
sharpening angle: 135 °
DIN steel grade: HSS-Co M42
steel grade according to GOST: P2M10K8-MP
cobalt content: ~ 8%
hardening surface coating: no
color: dark bronze
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.
