Dormer 7189840 | 4.20mm Drill Size x 4.20mm Shank x 14.00mm Flute Length x 55.00mm OAL x 120 Degree Point Angle Steam Tempered Coated HSS A119 Stub Drill

The A119 is a short drill designed primarily for drilling holes through sheet metal. It is manufactured from high speed steel, making it suitable for drilling in many materials including steel, aluminium and stainless steels. The steam oxide finish helps stop workpiece material from sticking to the cutting edge of the drill. The A119 has a 120 Degree conventional point to aid self-centering, and the core of the drill is thinner than normal which helps reduce the amount of force needed when drilling. The drill comes in a number of metric diameters and is designed without the normal body clearance to improve hole roundness when drilling sheet metal. Finally, the drill is actually double ended, so you can use either end to drill, giving you twice the tool life! .
