Set of 3 pcs with step drills HSS-Co. TiAlN

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

Pre-drilling and punching are completely eliminated

Included diameters: 4-12 mm (at 1 mm intervals), 4-20 mm (at 2 mm intervals) + 4-30 mm (at 2 mm intervals)

Design:

• cobalt content 5%
• Titanium-Aluminum-Nitride (TiAlN) coated
