RUKO VOB set da 6 pezzi di frese a tazza HSS con gambo Weldon, 12-22 mm

This RUKO VOB set bundles six HSS annular cutters with Weldon shanks, covering the most common hole diameters from 12 to 22 mm. The 3/4-inch shank fits directly into magnetic drilling machines and, with a suitable adapter, into pillar drills. Each cutter is ground from high-speed steel and has a 30 mm cutting depth, making the set a practical choice for steel, stainless steel, non-ferrous metals and light alloys.

Highlights

• Six core drills: 12, 14, 16, 18, 20 and 22 mm diameter
• Weldon shank, 19 mm (3/4 inch), for secure tool holding
• High-speed steel, ground, with multi-tooth cutting geometry
• 30 mm cutting depth for sheet and profile work
• Supplied in a robust plastic case

In daily use

The set covers the most frequently needed diameters, so you can switch quickly between hole sizes without changing the tool holder. The Weldon shank transmits torque reliably and prevents the cutter from slipping, even under high feed pressure. The bright, uncoated surface allows easy inspection of the cutting edges and keeps the cutters ready for resharpening.
