3pc cone countersink made of baked steel, finely ground CBN
wheel
Number run: 3
A …AAhel bA… â „c itA… —: 90st.
Maximum diameter: 31 mm
Minimum diameter: 4, 2 mm
Clamping shank: 12mm
Total length: 71mm
Coating: BLUE-TEC, increases service life countersink when cutting with very limited cooling(spray, paste), so cutting cutting dry
Material: HSSE-PM(baked powder cobalt high speed steel)
Standard: DIN335 C
Application:
Alloy steel with tensile strength up to 1400N / mm2
Stainless steel steel with tensile strength up to 900N / mm2
Gray cast iron
Alloy aluminum containing silicon> 10%
Copper, brass, plastics
Hardox, Hastelloy, Inconell, Nimonic and other special alloys
Properties:
Excellent drainage, run, run not guesses, the resulting surface without scratches, great centering tools-holes
