Product information
Carbide 3-blade cone countersink
Number run: 3
angle run: 90st
Maximum diameter: 20.5 mm
Minimum diameter: 3.5 mm
Clamping shank: 10mm
Total length: 63mm
Coating: BLUE-TEC, increases life of the countersink at cutting with very limited cooling(spray, paste), so i cutting dry dry
Material: carbide(pr. 4,3 to 11,5 all-hard design, 12,4-31mm carbide head with soldered shank made of tool steel)
Standard: DIN335 C
Application:
Hardening steel up to 50 HRC
Alloyed steel with tensile strength up to 1400N / mm2
Stainless steel with tensile strength up to 900N / mm2
Gray cast iron
Alloy aluminum with silicon content> 10%
, brass, plastics - Hardox, Hastelloy, Inconell, Nimonic and other special alloys
Properties:
Excellent drainage chip, run not tipped, resulting surface without scratches, great centering tools-holes
The grooves of the countersink are cut with a fine diamond wheel, thanks to what is to run sharper and smoother in comparison with common countersinks, where the grooves are milled.
The is always the highest Â!A… Â!Afm point diameter, ie when countersinking the material does not rub against the wall of the countersink, Af AfmAfÂ3 se decreases necessary cutting force and decreases also generated heat -> which increases life of the countersink.
