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.
