Design:
HSS-Co, AlTiN coated surface, with Weldon shank ∅ 19 mm,
2 carrier surfaces and 1 countersink for Rota-Quick
®
.
Inner hole 6.35 mm.
Application:
For use in magnetic base drills and column drills with MK
mount. The core drill only machines a thin material ring. The remaining
drill core is ejected by a guide and ejector pin using spring force.
The chips are quickly moved up for disposal and the risk of breakage
minimised. Even large drilling diameters require relatively low amounts
of energy. The core drill machines only a small part of the overall area
in comparison to the spiral drill. This results in huge savings in power
and time.
