What it is
The Fervi A014/03-14 tapered hole reamer is a cutting tool designed to enlarge and deburr holes in sheet metal and thin materials. Thanks to its tapered profile, it covers a diameter range from 3 to 14 mm, making it possible to obtain holes of different sizes with a single tool. Made in Italy, it complies with the Machinery Directive 2006/42/EC with CE marking, guaranteeing safety and build quality.
The step drill bit, or conical drill, is a cone-shaped cutter with steps that drills thin sheet metal and enlarges existing holes to the required diameter.
What it is for
Used for drilling steel, stainless steel and aluminium, on a pillar drill or with a hand-held drill, in metalworking and for deburring metal after cutting and drilling.
How to use it
Fit it in the drill and work at low speed on well-clamped sheet, advancing until the step reaches the desired diameter. Lubricate on metal and keep light pressure so that the hole does not go out of true. Remove the burrs after drilling. Not suitable for thick materials.
