Dormer A920 short drill bit is available in an extensive range of fractional and metric diameters. Part of the Dormer PFX range of drills, the A920 has a parabolic flute design, meaning deeper holes can be drilled in a single pass. The tool is made of high speed cobalt and can be used to drill a range of different materials such as aluminum, steel and stainless steel, while the bright surface means that the workpiece material does not stick to the cutting edge of the tool. The A920 has a 130 degree point angle that helps center the tool itself onto the hole and means less force is needed to drill into the workpiece. The A920 PFX drill bit is a powerful tool and produces good quality and accurate holes (up to H10 hole tolerance) even at high speeds and feeds.
