Product information
Designed for long lifetime and high cutting performance / Always use the recommended operating speed, speed to be increased slowly till a slight cutting is noticed; to avoid overheating, abrasive or breaking out of cutting teeths. / When drilling in metals (except cast iron) always use sufficient cutting-oil / Remove regularly drilling chips from the cutting spiral / Do not use high working pressure and assure that the saw does really cut. / The centre drill must exceed the saw teeth by approximate 3 - 4 mm but no more than the thickness of the workpiece / Make sure that the hole saw always is in vertical position to the work piece surface
