Step drill OREN with spiral flute, HSS 6-30 mm, 2 mm steps

Step drills are used for drilling cylindrical holes, which edges are at the same time knocked down by the next step.

Design:

• Drilling diameters are clearly marked on the individual steps
• Equipped with a spiral groove and deburring zone
• The spiral groove ensures better chip removal and faster and more stable drilling
• The deburring part is used to deburr the underside of the processed material
• The tip is with a split point - punching and pre-drilling is completely eliminated
