Product Description

Karnasch POWER-MAX Hole Saws offer best flexibility because it's :


"Easy-Change" quick-change arbour / holder system for almost unlimited use on hand-drilling machines, pillar drilling machines, radial drilling machines, turning machines and core drilling machines.


The POWER-MAX hole saw range permits processing of almost every steel type, from construction steels to stainless steels. It is also great for drilling in non-ferrous metals such as aluminium, copper and brass and ideal for drilling in plastics, CFK / GFK and sandwich-material. POWER-MAX Hole Saws are available in the diameter range of 14 - 150mm, at cutting depths of 12 - 60mm.


With an optimised design specifically for hand drilling machines, Karnasch offers Carbide Tipped Hole Saws from the EASY-CUT series. The thin cutting width of only 1.8mm enables fast and smooth drilling at low cutting pressure, excellent guidance and control. Applications include drilling in steel, stainless steel, non ferrous-metals such as aluminium and copper, as well as plastic, GFK / CFK, cast iron and sandwich material. Available in diameter 14-150mm


The EXTRA-EASY-CUT Hole Saw has special smooth-running properties for perfect use on cordless drilling machines even with limited battery power. Available in diameter 14-38mm


Also new are the DIAMOND-GRIT Hole Saws for use in abrasive and very hard materials such as glass, fibre-glass and carbon-reinforced plastics, ceramics, stone, porcelain, brick and masonry. Heavy design with solid base plate for extra stability and best concentricity. Available in diameter 14-152mm.


Of course, the BI-METAL Hole Saws M42 are part of the delivery range as well now with an enlarged diameter range (14 - 305mm) and an enlarged range of Hole Saw kits. Now with a new designed HEAVY-DUTY arbour for large Hole Saws 32-305mm. Also available finally a Rim Countersink for perfect assembly of sockets in e.g. gypsum, plaster board, wood and similar materials.


Suitable for drilling in steel, thin metal sheet, sandwich materials, non ferrous-metals such as alu, copper, brass, wood and wooden materials, plastics and many others.


The Hole Saw range is completed by MINI Cut HSS M2 Hole Saws for hand-guided machines and cordless drills. The very thin cutting width of only 2.3 mm generates little cutting pressure, avoids deformation of the sheets and thus is the ideal drill for electricians, sanitary and heating installers, sheet processing, maintenance installations, automotive aftermarket, conduit work and many others. The MINI CUT Hole Saws produce extremely fast, clean and almost burr-free holes in the thinnest of sheets up to plates with a thickness of 13mm. Excellent also for removing spot welds (automotive sheets). All MINI-CUT Hole saws comes with TIN-GOLD coating for best performance also in stainless steel and extended service life. Available from diameter 6-25mm.
