KWB 513050 Set de 3 avellanadores de punta cónica 4/5/6 mm HSS con vástago hexagonal

This KWB countersink set combines three common sizes in one compact blister pack, so you can switch quickly between 4 mm, 5 mm and 6 mm countersinks without hunting for separate bits. The high-speed steel cutting edges are matched with a 1/4-inch hex shank, which locks into standard drill chucks and quick-change holders for fast bit swaps.

Highlights

• Three countersink sizes: 4 mm, 5 mm, 6 mm
• High-speed steel (HSS) for clean cuts in wood, plastic and non-ferrous metals
• 90-degree countersink angle for standard flat-head screws
• 1/4-inch hex shank with quick-change compatibility
• Blister pack keeps the set organised

In daily use

The set covers countersinking, deburring and chamfering tasks in soft materials. The hex shank prevents slipping in the chuck and allows one-handed bit changes in drills and impact drivers that accept 1/4-inch hex accessories.
