About this product
The Dormer A777 is a heavy-duty jobber drill bit made from HSS-E cobalt steel (8% cobalt), giving high hardness and resistance to heat and wear. This makes it suited to professional and industrial drilling, including tougher, higher-tensile materials such as those used in aerospace work.
It features a 135° split point ground to NAS907 type P3 specification, which reduces walking and improves precision, along with a standard right-hand spiral flute and thick web design. The bit has a bronze finish and conforms to DIN338.
This 7.50mm bit has an overall length of 109mm and a working length of 69mm.
