Rubber Drill Bits
ERB Tubular Rubber Drills are seamless tubes with an extremely thin wall.
They are made of an alloyed special tool steel, hardened and precisely grinded. ERB heavy-duty rubber drills guarantee a long lasting cutting because of the special tool steel used.
All tubular drilling holders are equipped with a No. 2 morse taper for direct mounting to conventional metal drilling machines as well as a side-on ejection-opening which guarantees perfect emptying of drilled parts.
Of course other attachments are possible as well.
ERB tubular drilling holders are staggered in sizes and will accept rubber drills in 10 mm range of steps in cutting diameters.
Example: Tubular drilling holder No. 1 = 1 – 10 mm drilling diameter
Tubular drilling holder No. 2 = 11 – 20 mm drilling diameter
Tubular drilling holder No. 3 = 21 – 30 mm drilling diameter
Tubular drilling holder No. 4 = 31 – 40 mm drilling diameter
