SET OF 3 HSS CONICAL DRILL BITS 4 - 32 mm

Cone drill bits are made of high-quality steel high-speed cutting HSS and covered shell With titanium, which ensures durability and sharpness for a long time of use. This makes them ideal for drilling in various materials, ensuring precise and effective drilling without the need to pre-drill and deform the material.

Gradation every 2 millimeters allows you to obtain holes of different diameters without having to change the drill. Laser cut numbering on allows precise control of the hole size during work, which translates into accurate and professional results.

MAIN ADVANTAGES

• Durable construction : High-quality HSS steel and titanium coating ensure long-term use and wear resistance.

• Universal application: Perfect for drilling in thin-walled and soft metals (copper), sheets, profiles (e.g. aluminum), as well as plastics (acrylic, PVC).

• Precise drilling: Thanks to graduated sizes every 2 mm and laser-cut numbering, it is possible to precisely control the size of the hole while drilling.

• Fast and smooth cutting : Thanks to two drill blades and a special groove design, the drilling process runs quickly and smoothly, without the risk of the tool jamming or material jamming.

• They are perfect for: home workshops and craft workshops.

• Universal hex shank (hex) 1/4" suitable for any screwdriver.

The set includes 3 drills:

• 4 - 12mm (4 – 6 – 8 – 10 – 12 mm)

• 4 - 20mm (4 - 6 – 8 – 10 – 12 – 14 – 16 – 18 – 20 mm)
